Abstract
Tele-sonography works on inherent assumption that the transmitted medical ultrasound videos scanned from remote patients contain the representative data for doing the diagnosis. Due to the high subjectivity involved in scanning and semi-skilled nature of the operating person, this assumption may not always be valid. The remotely scanned ultrasound video contains a lot of redundant information, which is not useful for diagnosis. Transmitting redundant and large volumes of medical data to the expert end for analysis may lead to faulty diagnosis, associated with high transmission cost, and also poses serious challenges on data storage, processing, infrastructure, etc. Addressing these issues, we propose a novel WebRTC based framework to detect representative frames in the ultrasound video and transmit only those frames to the remote sonographer for getting a diagnosis. Detection of representative frames in ultrasound video is done with invariant scattering convolution network. The entire framework is developed using WebRTC, which enables the browser to browser communication thus reducing the computation on end ultrasound scanner and ensures ubiquitous and secured connectivity between technician and the sonographer. The proposed video validation algorithm achieved an accuracy of 96.5% in classifying the representative frames and nonrepresentative frames in the ultrasound video.
