Reflex transmission imaging improves ultrasonic visualization and characterization of calculi for lithotripsy applications.
A new ultrasound technique combining reflex transmission imaging (RTI) and integrated reflection C-scan (IRCS) imaging is being developed to enhance visualization of calculi for lithotripsy applications. Reflex transmission imaging/integrated reflection C-scan ultrasound produces orthographic images (similar to flat-field x-ray films) that improve the delineation of stone from soft tissue. Integrated reflection C-scan imaging is based on reflectivity while RTI is based on transmissivity of structures (stones) in the focal plane. Quantitative measurements of reflectance (IRCS) and attenuation (RTI) show potential for stone characterization and assessment of the degree of fragmentation. In vitro and in vivo images are presented.
