Bone segmentation applying rigid bone position and triple shadow check method based on RF data.

Noninvasive 3D reconstruction of a bone requires very accurate 2D navigated scans of bone. The use of brightness-mode ultrasound seems to be promising, if some 2D scans of bone are obtained in a fully automatic manner. This paper presents a rapid and fully automatic method for segmenting bone in a standard 2D ultrasound image (B-mode image).

Localization of significant coronary arterial narrowings using body surface potential mapping during exercise stress testing.

The ability of body surface potential mapping to localize coronary arterial narrowings during exercise stress testing was investigated. An array of 48 chest wall electrodes, simultaneously recorded, was used. Digital filtering and signal processing, data reduction techniques and discriminant analysis were applied to process the information.
