МРТ для DataScience. Часть 4

Продолжаем разбираться со особенностями МРТ-данных для обучения нейронных сетей. Содержание и первые части цикла статей здесь.

4. Геометрия МРТ изображений

4.1. Размеры и значения пикселей\вокселей

Дискретность К-пространства естественным образом влечет за собой обобщение реальных данных в пределах одного элемента матрицы и, в последующем, в пределах одного пикселя итогового изображения. Реальные размеры пикселей задаются в миллиметрах.

Однако сигналы объединяются не в плоскости, а по объему, третьим измерением которого является толщина слайса. Даже если рассматривать отдельные слайсы, т.е. 2D-изображения, каждый пиксель все равно будет иметь значение, соответствующее совокупности всех сигналов вокселя.

Для достаточно крупных однородных органов или тканей такая дискретизация несущественна. Однако для мелких объектов и в случае попадания границы между разными тканями внутрь одного вокселя могут возникать искажения, которые затрудняют диагностику. Например, если раковый узел имеет диаметр 2 мм, а толщина слайсов выбрана 3 мм или более.

Рисунок 24. Изображения для толщины слайса в 3 мм (слева) и 10 мм (справа) [7]
Рисунок 24. Изображения для толщины слайса в 3 мм (слева) и 10 мм (справа) [7]

Ситуацию может усугубить еще один параметр исследования – расстояние между слайсами. Это реальное расстояние в мм между центрами слайсов по соответствующей оси. Если оно больше толщины слайсов, то образуются зазоры, информация из которых потеряна. Если меньше, то слайсы частично перекрывают друг друга. Потерянную информацию полностью восстановить невозможно, хотя существует множество способов 3D-реконструкции с интерполяцией промежуточных данных (например).

При интерпретации значений пикселей нужно иметь в виду еще один важный параметр исследования – количество усреднений, т.е. количество повторов ИП, сигналы которых усредняются. При неоднократном повторе сигнал от одной и той же области будет одинаковым, а шум каждый раз разным, и при усреднении соотношение сигнал\шум будет выше. Но и время исследования это увеличивает кратно количеству повторений.

При компьютерном анализе изображений необходимо понимать специфику значений пикселей\вокселей. Например, если при сегментации на слайсах с границей органа\ткани модели начинают вести себя нестабильно (здесь выделяют, а здесь нет). Или если речь идет об обнаружении мелких объектов, изображения которых могут сильно отличаться в разных исследованиях и даже в разных сериях одного исследования из-за суммирования с сигналами от разных объемов соседних тканей внутри одного вокселя. Или при использовании в датасете слайсов с разным размером вокселей… И т.д. И т.п.

Реальные размеры пикселей, толщина слайсов и расстояние между ними (все в миллиметрах) сохраняются в тэгах DICOM-файлов:

  • (0028,0030) Pixel Spacing

  • (0018,0050) Slice Thickness

  • (0018,0088) Spacing Between Slices

Что касается самих значений, то они обычно представляются в целочисленной шкале от 0 (самый темный пиксель, самая низкая интенсивность сигнала) до N (самый светлый, самая высокая интенсивность). Максимальное значение может составлять от нескольких сотен до десятков тысяч. К сожалению, в МРТ нет единого стандарта, поэтому исследования, проведенные на разных МР-томографах, нельзя сравнивать друг с другом по абсолютным значениям. И даже разные серии одного исследования могут иметь разное распределение значений, т.к. интенсивность сигнала увеличивается с размером вокселя. При иной толщине слайса или размерах пикселей яркость и контраст изображений будет другим.

Целочисленные шкалы вызывают и другие проблемы в DS-задачах. Например, затруднительно использовать аугментации и предобученные нейронные сети, которые имеют дело со значениями в диапазоне от 0 до 255. Простое преобразование исходной шкалы к этому диапазону приведет к потере данных, которая может оказаться существенной. Особенно, если распределение сильно скошено, а шкала достаточно длинная.

Таким образом, для DS-задач, особенно использующих разнородные данные, остро стоит проблема выравнивания распределений.

4.2. Поле зрения (FOV)

Поле зрения (Field of View, FOV) – это часть тела пациента, представленная на слайсе.

Во время исследования задается FOV, размер К-пространства и итоговые размеры слайсов, из которых потом рассчитываются реальные размеры пикселей. Для получения изображения с высоким разрешением нужны маленькие пиксели, т.е. FOV должен быть меньше и\или матрица К-пространства больше.

Ограничения на время исследования, мощность аппаратуры и интенсивность сигналов из маленьких вокселей ограничивают и размер К-пространства сверху. А FOV не может быть меньше исследуемой области. К тому же, выбор параметров операторами томографов не всегда оптимален с точки зрения качества данных для DS. Поэтому в обучение и, затем, в инференс нейронным сетям попадают изображения с разным, иногда достаточно низким разрешением.

Рисунок 26. Большой FOV и маленькое К-пространство приводят к низкому разрешению изображений [4]
Рисунок 26. Большой FOV и маленькое К-пространство приводят к низкому разрешению изображений [4]

В тэгах DICOM-файлов размер К-пространства присутствует не всегда, но даже если он есть, последующий ресайз слайсов до целевого размера делает это значение не столь важным. Информации о FOV обычно там нет, но его можно оценить, умножив размеры пикселей на высоту и ширину слайса. Это может оказаться полезным, например, при балансировке датасета по масштабу представленных изображений.

Также величину FOV можно использовать в препроцессинге для ресайза слайсов до единых размеров пикселей, чтобы уменьшить разнообразие по этому параметру. Искажения при масштабировании с учетом уже имеющихся могут оказаться менее важными для нейронных сетей, чем разнородные размеры пикселей.

4.3. Системы координат

В МРТ-исследованиях применяются 3 системы координат (СК):

  • Глобальная (World Coordinate System) – декартова СК, которая привязана к томографу. Единая СК для всех данных исследования. Единицы измерения – миллиметры.

  • Анатомическая (например, LPS - Left, Posterior, Superior или RAS - Right, Anterior, Superior) – привязана к пациенту, предназначена, в первую очередь, для определения плоскости и направления сканирования: Right:Left, Anterior:Posterior, Superior:Inferior. LPS и RAS – разные СК, которые отличаются только направлением осей. LPS используется, например, в формате DICOM и библиотеке ITK toolkit (см. далее). RAS используется, например, в 3D Slicer.

  • СК изображения (IJK Coordinate System – pixel(I,J) & slice K, или IRC Coordinate System – Index, Row, Column) – привязана к конкретному слайсу или 3D-объему, предназначена для идентификации положения пикселей\вокселей относительно данных.

В разных публикациях и документациях можно встретить различные названия систем координат, что может вызвать путаницу. Однако для DS-задач важно не их название, а суть и содержащие нужную информацию DICOM-тэги.

Можно упрощенно считать, что для каждого исследования существуют 2 системы координат:

  • Глобальная – единое пространство, в котором «существуют» все серии исследования. Начало координат задается оператором в привязке к исследуемой области тела пациента. По умолчанию оси направлены по схеме LPS. Единицы измерений – миллиметры.

  • Локальная – система координат каждого слайса каждой серии. Ее начало координат (левый верхний угол изображения) и направления осей относительно глобальной СК содержатся в тэгах каждого DICOM-файла. Единицы измерений – пиксели.

Область в пространстве глобальной СК, которую занимает отдельный слайс, определяется следующими параметрами изображения:

  • Начало координат (Origin) – координаты центра левого верхнего вокселя слайса в глобальной СК. DICOM-тэг (0020,0032) Image Position (Patient).

  • Интервалы (Spacing) – вектор расстояний между центрами пикселей вдоль каждого из измерений в единицах глобальной СК. DICOM-тэг (0028,0030) Pixel Spacing.

  • Размер (Size) – количество пикселей в каждом измерении. DICOM-тэги (0028,0010) Rows и (0028,0011) Columns

  • Матрица направляющих косинусов (Direction cosine matrix) — косинусы углов между осями локальной и глобальной СК. DICOM-тэг (0020,0037) Image Orientation (Patient). Хранится как одномерный вектор.

Рисунок 28. Геометрические параметры изображения [источник]
Рисунок 28. Геометрические параметры изображения [источник]

Начало координат локальной СК соответствует центру пикселя с координатами (0, 0). В отличие от представленного выше рисунка, такой пиксель обычно расположен в левом верхнем углу изображения. И соответствующие оси направлены вдоль первой строки (слева направо) и первого столбца (сверху вниз). Также на этом упрощенном рисунке не представлены z-координаты и направляющие косинусы с осью Z.

Объемность пикселя\вокселя приводит к тому, что реальная область пространства, которую занимает изображение, выходит за координаты крайних точек на полуинтервал по каждой оси. Это важно при расчетах и преобразованиях, где требуется высокая точность или точное сопоставление разных изображений в едином пространстве глобальной СК.

Указанные параметры часто применяются на практике, например, для решения следующих задач:

  • Расчет FOV по размерам слайса и расстоянию между центрами пикселей.

  • Упорядочивание слайсов в серии, например, для прямой аксиальной проекции – по z-координате начал отсчета слайсов.

  • Определение проекции по направлению осей локальной СК по отношению к осям глобальной.

  • Отбор серий и балансировка датасетов по, например, размерам вокселей и проекциям.

  • Сопоставление разных серий и интерполяция пикселей для полного совпадения слайсов (регистрация серий – см. далее).

  • Расчет реальных размеров органов, их зон и патологий.

  • И т.д.

Перевод координат из локальной в глобальную СК осуществляется по следующей формуле:

[источник]

где:

  • [i, j] – координаты пикселя в локальной СК,

  • [x, y, z] – координаты того же пикселя в глобальной СК,

  • [Xx, Xy, Xz, Yx, Yy, Yz] – вектор направляющих косинусов (Direction cosine matrix),

  • [Dr, Dc] – вектор интервалов (Spacing) для строки и столбца соответственно,

  • [Ox, Oy, Oz] – вектор начала координат (Origin).

Все вышеописанное в полной мере относится к случаю, когда слайсы сохранены в 2D, т.е. каждый в своем DICOM-файле. Для данных, сохраненных в 3D в едином DICOM-файле, ситуация несколько иная – начало координат локальной СК задается для всего объема, а начало координат каждого слайса определяется исходя из других параметров.

Да и в 2D не все так просто и логично, как могло показаться. На практике можно столкнуться, например, с сильно «косыми» сериями, для которых алгоритм упорядочения по координатам не так тривиален. Другой случай – непараллельные слайсы, которые создают множество проблем, начиная от дробления одной серии на несколько с разными идентификаторами, заканчивая сохранением результатов разметки в едином 3D-объеме, как этого требует формат DICOM SEG.

В любом случае, как и ко всем DICOM-тэгам, к этим значениям нужно относиться настороженно и перед использованием проверять все, что только можно.

    "In the crypto world, this is great news I want to share. Last year, I fell victim to a scam disguised as a safe investment option. I have invested in crypto trading platforms for about 10yrs thinking I was ensuring myself a retirement income, only to find that all my assets were either frozen, I believed my assets were secure — until I discovered that my BTC funds had been frozen and withdrawals were impossible. It was a devastating moment when I realized I had been scammed, and I thought my Bitcoin was gone forever, Everything changed when a close friend recommended the Capital Crypto Recover Service. Their professionalism, expertise, and dedication enabled me to recover my lost Bitcoin funds back — more than €560.000 DEM to my BTC wallet. What once felt impossible became a reality thanks to their support. If you have lost Bitcoin through scams, hacking, failed withdrawals, or similar challenges, don’t lose hope. I strongly recommend Capital Crypto Recover Service to anyone seeking a reliable and effective solution for recovering any wallet assets.

    Writing this review is a joy. Marie has provided excellent service ever since I started working with her in early 2018. I was worried I wouldn't be able to get my coins back after they were stolen by hackers. I had no idea where to begin, therefore it was a nightmare for me. However, things became easier for me after my friend sent me to [email protected] and +1 7127594675 on WhatsApp. I'm happy that she was able to retrieve my bitcoin so that I could resume trading.

    God bless Capital Crypto Recover Services for the marvelous work you did in my life, I have learned the hard way that even the most sensible investors can fall victim to scams. When my USD was stolen, for anyone who has fallen victim to one of the bitcoin binary investment scams that are currently ongoing, I felt betrayal and upset. But then I was reading a post on site when I saw a testimony of Wendy Taylor online who recommended that Capital Crypto Recovery has helped her recover scammed funds within 24 hours. after reaching out to this cyber security firm that was able to help me recover my stolen digital assets and bitcoin. I’m genuinely blown away by their amazing service and professionalism. I never imagined I’d be able to get my money back until I complained to Capital Crypto Recovery Services about my difficulties and gave all of the necessary paperwork. I was astounded that it took them 12 hours to reclaim my stolen money back. Without a doubt, my USDT assets were successfully recovered from the scam platform, Thank you so much Sir, I strongly recommend Capital Crypto Recover for any of your bitcoin recovery, digital funds recovery, hacking, and cybersecurity concerns.

    Hi. Please be wise, do not make the same mistake I had made in the past, I was a victim of bitcoin scam, I saw a glamorous review showering praises and marketing an investment firm, I reached out to them on what their contracts are, and I invested $28,000, which I was promised to get my first 15% profit in weeks, when it’s time to get my profits, I got to know the company was bogus, they kept asking me to invest more and I ran out of patience then requested to have my money back, they refused to answer nor refund my funds, not until a friend of mine introduced me to the NVIDIA TECH HACKERS, so I reached out and after tabling my complaints, they were swift to action and within 36 hours I got back my funds with the due profit. I couldn’t contain the joy in me. I urge you guys to reach out to NVIDIA TECH HACKERS on their email: [email protected]

    CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time.
