Abstract
The wireless transmission of medical video is expected to see significant growth in the coming years. This is primarily due to the expected availability of significant bandwidth in the next-generation of wireless communications networks, and the emergence of effective wireless video-compression standards. The design of wireless medical video transmission systems presents unique requirements for error-resilience and clinical validation. We present a tutorial introduction to the most important components of a wireless medical video transmission system. We focus on video-encoding requirements for error resilience, quality-of-service transmission, and diagnostic validation. Whenever possible, we give references to open-source software and provide references to the literature. We demonstrate the basic principles through the use of simple examples of stroke ultrasound videos.

This paper introduces a new clinical distortion index able to measure the decrease in diagnostic content in compressed echocardiograms. It is calculated using cardiologists' answers to a clinical testbed composed of two types of tests: one blind and the other semi-blind. This index may be used to compare clinical performance among video codecs from a clinical perspective. It can also be used to classify compression rates into useful and useless ranges, thus providing recommendations for echocard...

H.264 is the ITU-T's new, nonbackward compatible video compression Recommendation that significantly outperforms all previous video compression standards. It consists of a video coding layer (VCL) which performs all the classic signal processing tasks and generates bit strings containing coded macroblocks, and a network adaptation layer (NAL) which adapts those bit strings in a network friendly way. The paper describes the use of H.264 coded video over best-effort IP networks, using RTP as the r...

The aim of this paper is to present a novel platform for advanced transmission of medical image and video, introducing context awareness in telemedicine systems. Proper scalable image and video compression schemes are applied to the content according to environmental properties (i.e., the underlying network status, content type, and the patient status). The transmission of medical images and video for telemedicine purposes is optimized since better content delivery is achieved even in the case o...

Abstract H.264/AVC is a new standard for digital video compression jointly developed by ITU-T’s Video Coding Experts Group (VCEG) and ISO/IEC’s Moving Picture Experts Group (MPEG). Besides the numerous tools for efficient video coding, the H.264/AVC specification defines some new error resilience tools. One of them is flexible macroblock ordering (FMO) which is the main focus of this paper. An in-depth overview is given of the internals of FMO. Experiments are presented that demonstrate the bene...

In real-time remote diagnosis of emergency medical events, mobility can be enabled by wireless video communications. However, clinical use of this potential advance will depend on definitive and compelling demonstrations of the reliability of diagnostic quality video. Because the medical domain has its own fidelity criteria, it is important to incorporate diagnostic video quality criteria into any video compression system design. To this end, we used flexible algorithms for region-of-interest (R...

Efficient medical video transmission over 3G wireless is of great importance for fast diagnosis and on site medical staff training purposes. In this paper we present a region of interest based ultrasound video compression study which shows that significant reduction of the required, for transmission, bit rate can be achieved without altering the design of existing video codecs. Simple preprocessing of the original videos to define visually and clinically important areas is the only requirement.

This paper introduces a cost-effective portable teletrauma system that assists health-care centers in providing prehospital trauma care. Simultaneous transmission of a patient's video, medical images, and electrocardiogram signals, which is required throughout the prehospital procedure, is demonstrated over commercially available 3G wireless cellular data service. Moreover, the physician can remotely control the information sent from the patient side. Such a technology will allow a trauma specia...

Abstract In ultrasound imaging and video visual perception is hindered by speckle multiplicative noise that degrades the quality. Noise reduction is therefore essential for improving the visual observation quality or as a pre-processing step for further automated analysis, such as image/video segmentation, texture analysis and encoding in ultrasound imaging and video. The goal of the first book (book 1 of 2 books) was to introduce the problem of speckle in ultrasound image and video as well as t...

In this study, we investigate how the recently introduced high efficiency video coding (HEVC) standard can be used in the design of reproducible medical ultrasound video diagnosis systems. We introduce a set of clinical criteria that are used to validate the clinical capacity of HEVC encoded atherosclerotic plaque ultrasound videos. The clinical criteria include the assessment of atherosclerotic plaque geometry, morphology, and motion. The efficiency of HEVC compared to prior video coding standa...

Employing multipath routing with video transmission can improve reliability and end-to-end delay. Many prior works investigate this combination in the scenario of wireless ad hoc networks, considering that at least two paths can be found. Nevertheless, the number of available paths is highly dependable on network topology and density. Thus, link-disjoint paths may not be available at a number large enough for exploring path diversity. A path selection strategy over source routing is proposed tha...

End-to-end delay is an important consideration of the design of wireless tele-ultrasonography systems because such systems support delay-sensitive applications and require critical delay constraints. This paper addresses the characterisation and estimation of end-to-end delay distributions by using the Effective Capacity (EC) technique. A cross-layer simulation platform is built to 1) represent a scenario of remote medical ultrasound video streaming over fixed WiMAX networks, 2) transmit a real ...

The application of advanced error concealment techniques applied as a postprocess to conceal lost video information in error-prone channels, such as the wireless channel, demands additional processing at the receiver. This increases the delivery delay and needs more computational power. However, in general, only a small region within medical video is of interest to the physician and thus if only this area is considered, the number of computations can be curtailed. In this paper, we present a tec...

Abdominal Aortic Aneurysm (AAA) is responsible for approximately 1.3% of all deaths among men over the age of 65. Given the fact that once an aortic rupture occurs mortality rates are estimated between 80%–90%, national AAA population screening programs are currently established as an effective prevention policy. Driven by the latest advances in mobile-health (m-health) systems and services, and more specifically medical video transmission telemedicine systems, the current study is directed towa...
