An m-health system for real-time wireless communication of medical video based on open-source software is presented. The\r\nobjective is to deliver a low-cost telemedicine platform which will allow for reliable remote diagnosis m-health applications such\r\nas emergency incidents, mass population screening, and medical education purposes. The performance of the proposed system is\r\ndemonstrated using five atherosclerotic plaque ultrasound videos. The videos are encoded at the clinically acquired resolution, in\r\naddition to lower, QCIF, and CIF resolutions, at different bitrates, and four different encoding structures. Commercially available\r\nwireless local area network (WLAN) and 3.5G high-speed packet access (HSPA) wireless channels are used to validate the developed\r\nplatform. Objective video quality assessment is based on PSNR ratings, following calibration using the variable frame delay (VFD)\r\nalgorithm that removes temporal mismatch between original and received videos. Clinical evaluation is based on atherosclerotic\r\nplaque ultrasound video assessment protocol. Experimental results show that adequate diagnostic quality wireless medical video\r\ncommunications are realized using the designed telemedicine platform. HSPA cellular networks provide for ultrasound video\r\ntransmission at the acquired resolution, while VFD algorithm utilization bridges objective and subjective ratings.
