Internal noise degrades the quality of a medical ultrasound imaging and thus, reduces its usefulness as a diagnostic tool. We study the effect of fusing multiple ultrasound pings on improving the quality of the ultrasound image. This approach is limited by the relative motion between the sensor array and internal organs, a problem which reduces the effect of the fusion. We present a robust moti...

Three-dimensional (3D) ultrasonography has been shown to be an accurate and appropriate tool for measurement of gallbladder volume in humans. Therefore, we applied this novel technique for the first time to study fasting and postprandial gallbladder volume in 10 healthy dogs and compared the results with those of 2-dimensional (2D) ultrasonography. Fasting gallbladder volumes determined by 3D u...
