Longport said it will extend its ultrasound and digitial technology to enable tumors in the breast and other regions to be visualized in real time. Longport's 20-MHz ultrasound technology enables imaging of the skin, including skin cancers, to very high resolutions (approximately 65 microns), to a depth of 3 centimeters (1 1/4 inches). The company said it is now believed possible to capture deeper sections of tissue (10 cm or 4 inches) with the same resolution, enabling breast tumors to be detected at an earlier stage and to be better monitored over the long term.
