Ultrasonic reflection tomography and tomographic parameter extraction for post-discotomic scarring diagnostics

An ultrasonic imaging system is presented for diagnostics of post discotomic scarring. The system consists of a conventional B-mode imaging system, using a 5 MHz sector scanner. The scanner is laterally moved over the patients back along a linear line. Thus several images of the same cross sectional plane are acquired by sampling the RF echo data. This data has been used for both, spatial compounding of the B-mode images and multidirectional extraction of the spectral parameters attenuation and backscattering
