Detection of atrial fibrillation episodes in long-term heart rhythm signals using a support vector machine [PDF]

, 2020
Atrial fibrillation (AF) is a serious heart arrhythmia leading to a significant increase of the risk for occurrence of ischemic stroke. Clinically, the AF episode is recognized in an electrocardiogram.

IMU‐Based Respiratory Signal Processing Using Cascade Complementary Filter Method

Journal of Sensors, Volume 2022, Issue 1, 2022., 2022
The purpose of this paper is to propose a cascade complementary filter (CCF) for tracking abdominal or diaphragmatic movement induced by respiratory activity. An inertial sensor (3 DOF accelerometer and 3 DOF gyroscope) is mounted on the upper abdomen, allowing the tilt value of the upper abdomen to be measured.

An open-source deep learning framework for respiratory motion monitoring and volumetric imaging during radiation therapy. [PDF]

Med Phys
Abstract Background Real‐time image‐guided radiation therapy (IGRT) was first clinically implemented more than 25 years ago but is yet to find widespread adoption. Existing approaches to real‐time IGRT require dedicated or specialized equipment that is not available in most treatment centers and most techniques focus exclusively on targets without ...
