Skilled cardiologists probe heart sounds by electronic stethoscope through human ears, but interpretation of heart sounds is a very special skill which is quite difficult to teach in a structured way. Because of this reason, automatic heart sound analysis in computer systems would be very helpful for medical staff. This paper presents a complete heart sound analysis system covering from the segmentation...
Ultrasound machine has been a useful diagnosis tool for several decades, and many researches tried to use computerized algorithms to help physicians diagnose diseases according to the ultrasound texture patterns. However, the effects of sampling format and the sampling rate on the texture feature were not treated properly. In this paper, the authors try to evaluate the effects of the scan conversion...

Ultrasound is an important way of physical examination nowadays. Many literatures tried to find a quantified standard for diagnosing ultrasonic images; however, they neglected the effect of scan-conversion on image textures. This paper provides a preprocessing method, which practically conforms to the ultrasound image formats, and then compares the effect of the preprocessing method. Several images...
