Abstract :
Doppler Tissue Imaging (DTI), as used at present, is angle-dependent. in that it only measures the velocity component along the ultrasound beam direction. There is an ongoing need in cardiology for imaging and measurement techniques which are angle-independent. Bandwidth Doppler techniques as have been described for blood flow have potential for angle-independent tissue motion measurement. Results are presented of BDTI signals from a tissue phantom and in vivo myocardium.
