Confusion and Direction in Diagnostic Doppler Sonography

Spectral and color sonographic Doppler information has become critical to medical imaging and diagnosis. However, there are no standards for the display of the Doppler frequency-shifted sonographic directional information. The display of the spectral and Doppler directional information is arbitrary and under operator control. The authors discuss the current situation of the Doppler directional displays and the problems that may be caused by this confusion.

Developing an automatic brachial artery segmentation and bloodstream analysis tool using possibilistic C-means clustering from color doppler ultrasound images
A software that is noise tolerant and fully automatic in segmentation of brachial artery from color Doppler ultrasound images is proposed and successfully extracts the target area in 59 out of 60 cases with field expert’s verification. Expand
Evaluation of the median nerve within the wrist during functional hand activity using ultrasonography
The findings from the studies show that the dynamic ultrasonographic technique can be used to image the median nerve during physical activity of the hand and that the novel quantification method can be use to measure the change in the parameters of the median nerves during physical hand activity and distinguish significant differences between the non-symptomatic median nerve and those symptomatic of an median nerve disorder.
