摘要：

Reflex transmission imaging (RTI) is a method for producing orthographic ultrasound transmission images, which depict focal-plane transmittance, by using a single transducer rather than an opposed transducer pair. RTI can be implemented using modified B-scan equipment, and a bidirectional scan probe. It has the further advantage of enabling simultaneous generation of integrated reflection C-scan (IRCS) images, which depict backscatter from the focal plane, in perfect registration with the transmission images. We describe these methods, demonstrate a new process by which the reflection and transmission images can be combined to produce a new image of superior quality, and demonstrate the applicability of this technique to improved visualization of kidney stones, with potential application to lithotripsy.
