Бесконтактная ЭКГ: биорадиолокация и ИИ в действии

Привет, Хабр!

Сегодня говорим про мониторинг жизненно важных показателей (ЖВП) человека. ЖВП — это метрики, по которым можно понять, всё ли в порядке с нашим организмом: температура тела, давление, дыхание, ну и наш сегодняшний герой — пульс.

Когда речь заходит о мониторинге сердечной активности, первое, что приходит в голову — это ЭКГ. Электрокардиография уже давно считается золотым стандартом в медицине. Однако при всех её достоинствах у ЭКГ хватает минусов: запись короткая, провода и датчики сковывают движения, есть риск раздражения и даже заражения при повреждении кожи, да и ощущения от процедуры так себе — в целом комфорт сомнительный.

Пора применять более современные методы. Речь идет о биорадиолокации (https://habr.com/ru/companies/etmc_exponenta/articles/859448/) — есть радар, направляя который на человека мы ловим отражённые волны от его грудной клетки. Затем полученные данные прогоняем через нейросеть и получаем полноценную ЭКГ.

Такой подход не требует контакта с телом, не ограничивает подвижность пациента — а значит, уменьшает артефакты и шумы, которые бывают при съехавших датчиках.

Всю эту красоту реализовал на нашем родном ресурсе Engee. Так что, если тема зацепила, то все демки, которые проводились над этой темой, можно почитать тут и тут

СНОВА ЭТИ НЕЙРОСЕТИ

Нейросети теперь везде и медицина не исключение. Нейросети используются для синтеза белков, точной сегментации раковых опухолей на снимках МРТ, помогают улучшать качество речи людям с нарушениями и дефектами разного рода и множество иных вещей.

Они отлично подходят для обработки сигналов ЭКГ. В нашем случае нейросеть решает задачу регрессии — реконструирует чистый сигнал из зашумленного. Биорадар, когда направлен на человека, улавливает не только сердечные сигналы, но и активность лёгких, плюс всевозможные шумы. А нейросеть превращает механическую активность в электрическую, понятную врачу.

С КАКИМ ДАННЫМИ МЫ РАБОТАЕМ?

Чтобы биорадар мог выдавать ЭКГ, необходимо обучить входящую в него нейросеть для реконструкции I/Q эхо-сигнала, отражающегося от грудной клетки. Для этого необходимы эталонные и измеренные данные.

В качестве эталонных сигналов является ЭКГ, в качестве измеренных – радарные сигналы. Оба типа сигналов сняты с одного человека при подключении электродов и направленного излучения радара. Важно, чтобы сигналы отображали одинаковую фазу работы сердца, для этого оба прибора работают одновременно. После получения сигналов, данные были оцифрованы и синхронизированы.

О том, как происходил сбор данных, можно почитать тут.

Визуализируем данные, чтобы понять с чем имеем дело:

df09ab8a6e55ad4c6b6b6316ee96f997.png

Визуализация показывает, что ЭКГ сигнал достаточно сильно зашумлен — а работать с необработанными квадратурной и синфазной составляющими нецелесообразно.

НАЧАЛО РАБОТЫ — ФИЛЬТРАЦИЯ ДАННЫХ

Первым делом обработаем сигналы. Начнем с ЭКГ.

Сначала сделаем фильтрацию на низких частотах для удаления дрейфа. Для этого применяем фильтр ФВЧ с аппроксимацией Баттерворта 5 порядка, где частота среза 0.5 Гц.

Далее выполняем фильтрацию режекторным БИХ фильтром для очистки сигналов от шумов сети переменного тока на частоте 50 Гц.

После фильтрации сигнал выглядит так:

a4ca529d820611b2c9673e2342c1236b.png

ФИЛЬТРАЦИИ ЭХО-СИГНАЛА

За счёт разделения радарного сигнала на I и Q каналы такие системы надёжно ловят слабые колебания грудной стенки. Но встречается проблема разбалансировки амплитуды и фазы между каналами.

Сначала с радарного приёмника снимается сырой I/Q-сигнал. Далее выполняется калибровка. В пространстве I–Q точки образуют эллипс. По его центру, полуосям и углу поворота оцениваются параметры амплитудного и фазового дисбаланса, после производится их компенсация. Для калибровки применяется метод алгебраической оценки параметров эллипса.

В идеальном случае сигнал от радара должен давать круг в I–Q плоскости, если цель двигается периодически.

МЕТОД ОЦЕНКИ ЭЛЛИПСА

Оценка параметров эллипса основывается на методе наименьших квадратов. Нужно найти параметры эллипса, которые наилучшим образом аппроксимируют заданный набор точек. В результате рассчитываются координаты центра, длины полуосей и угол поворота эллипса относительно осей координат.

НОРМАЛИЗАЦИЯ И ОБРАБОТКА I/Q-СИГНАЛА

На этапе обработки эхо-сигнала крайне важна его нормализация. Это необходимо для переноса эллипса, описывающего амплитуду и фазу сигнала, в начало координат. Такой перенос упрощает последующие операции — поворот и масштабирование, необходимые для приведения эллипса к единичному кругу.

Ниже отображается сигнал на комплексной окружности до всех преобразований.

4c5c7f2e36e860bc85674208ff3df305.png

Сначала выполняется центрирование сигнала.

Q = \operatorname{Im}\{IQ\} - y_cI = \operatorname{Re}\{IQ\} - x_ccf445d21c6d8b63a91de28aa2d2a50fc.png

Затем координатная система поворачивается так, чтобы полуоси эллипса стали параллельны осям.

\begin{pmatrix} I' \\ Q' \end{pmatrix} = \begin{pmatrix} \cos(\theta) & \sin(\theta) \\ -\sin(\theta) & \cos(\theta) \end{pmatrix} \cdot \begin{pmatrix} I \\ Q \end{pmatrix}fc216321bde78a4d721d60197be1c0a6.png

После этого сигнал масштабируется.

I_{final} = \frac{I'}{a}Q_{final} = \frac{Q'}{b}ea33bf879c7fe41fbd52a8b79a43b37d.png

В идеальном состоянии нужно получить окружность одного радиуса. Но мы и так неплохо отмасштабировали и отцентрировали данные.

ВЫДЕЛЕНИЕ ФАЗЫ И ОЦЕНКА ПЕРЕМЕЩЕНИЯ

Из нормализованного сигнала извлекается фаза, которая связана с микродвижениями грудной клетки.

\varphi = \operatorname{arctg} \left( \frac{Q_{final}}{I_{final}} \right)ed73b063cdd5aea6cfcf04623658fd07.png

Далее фаза преобразуется в линейное смещение грудной клетки. При этом исключается постоянная составляющая, чтобы смещение на начальном этапе считалось нулевым.

R = \frac{\varphi}{4 \pi} \lambda - R_07a071ae8ff762863bfbdca9338577cc4.png

Такой подход позволяет отслеживать изменения положения, игнорируя абсолютную дальность до объекта.

ВЫДЕЛЕНИЕ ЖИЗНЕННО ВАЖНЫХ ПОКАЗАТЕЛЕЙ ПЕРЕД ПОДАЧЕЙ В ИНС

После получения смещения нужно выделить такие показатели, как пульс и дыхание. Для этого используем фильтры, настроенные на тот диапазон частот, в котором находится тот или иной показатель.

Диапазон частот от 0.05 Гц до 0.5 Гц выбран для дыхания, так как частота дыхания у человека обычно находится в пределах 12–30 вдохов в минуту. Полосой от 1 Гц до 6 Гц выделяется пульсовой сигнал, отражающий сердечные сокращения.

Построим выделенные с помощью фильтров графики.

85fd1ae376ab1af8a761c47d06cd3371.png5ef4222510c9e39bf1f9b1e5b22ccca8.png

Для получения сердечного сигнала рассчитывается вторая производная от смещения — ускорение грудной стенки — позволяющая лучше выявлять резкие изменения в пульсовом сигнале. Вычисляется по формуле ниже.

a(t) = \frac{d^2 R(t)}{dt^2}74f73607b1e8dc6a8a47c3ec1d1ac6b0.png

НЕЙРОСЕТЬ

В качестве нейронной сети рассматривалась UNet модифицированная. Ее архитектура представлена на рисунке ниже.

d911e6c1731b67f8fb3481505ddbe7db.jpg

Как видно, она состоит из расширяющихся в ширину сверточных слоев ConvBlock и сужающихся транспонированных сверточных слоев – UpBlock. Далее представлена архитектура отдельного блока.

99a54f57dabc4d1f39e522344ff13737.png

Как видно на рисунке, в ConvBlock есть блок сжатия-расширения (SEBlock), который отвечает за выделение на картах признаков полезных признаков. Ниже ее архитектура.

Данная модель ИНС реализована на ЯП Julia – основная рабочая лошадка среды Engee. Модель была обучена на данных и переведена в формат ONNX.

ПАРАДИГМА МОП

Я также не обошел стороной парадигму МОП и реализовал модель ИНС в виде блоков в Engee.

Концепция остается той же. На входе источник данных – блок FromWorkspace – аналог радара. Данные поступают от источника необработанные, далее стоит блок обработки данных радара, где делается реконструкция эллипсом, масштабирование и все вышеперечисленное. Этот блок реализован через «Engee Function», который позволяет использовать пользовательский код.

Выделение ЖВП осуществляется через блок «Дискретный фильтр», которые реализует поведение КИХ фильтра. Коэффициенты фильтра были получены через встроенное приложение «Дизайнер фильтров», который позволяет в удобном режиме вычислить те самые коэффициенты числителя и знаменателя для необходимой частотной избирательности.

После этого следует еще один блок Engee Function в котором реализуется расчет ускорения смещения грудной клетки и срез — из поступающего вектора длинны N он выдает несколько окон длинны L. Далее окна передаются в блок с ИНС.

Блок ИНС также реализован через Engee Function, он работает с нейросетью через ONNX библиотеку на языке С (ЯП Julia позволяет такие обращения).

Итоговая модель представлена на рисунке внизу.

РЕЗУЛЬТАТЫ

Теперь пришло время оценить способности нашей сети в работе. Посмотрим, как она ведет себя на данных, которые еще никогда не встречала.

На рисунках выше видно, что из шумного радарного сигнала сеть получила ЭКГ, где наблюдаются повторения PQRST комплексов.

Также при обучения нейронной сети велось логирование данных, поэтому можно оценить рассчитанные метрики.

0106717f06d7872ff5fde217560375a1.png

С ростом числа эпох MAE и RMSE быстро уменьшаются. Сначала они падают (RMSE с ~0.25 до ~0.10, MAE с ~0.18 до ~0.05), а после пятидесяти эпох почти выровнялись и держатся на минимальных значениях. Коэффициент детерминации стабилизируется примерно в районе 0.85. Это говорит о том, что модель всё лучше объясняет поведение данных. Точность достигает около 0.85–0.9, то есть в 85–90% случаев модель предсказывает значение с ошибкой меньше, чем 0.05.

Конечно, для того, чтобы данную систему биорадара применять в реальной жизни необходимо обучать нейронную сеть на максимально разнообразных данных, где присутствуют тысячи человек как со здоровым сердцем — так и с различными патологиями.


ЗАКЛЮЧЕНИЕ

Данная статья рассказывает как обучить нейронную сеть для реконструкции ЭКГ и радарных данных, а также наглядно показывает возможность внедрения всего цикла работы системы – предобработку и инференс модели – в блочную систему отечественного продукта Engee. Результаты работы положительные.

    Don’t be deceived by different testimonies online that is most likely wrong.

    "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.

    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.
