UMD: Ultrasonic scanning systems consisting of an ultrasonic scanner, transducers (typically from 2 to 5 MHz), abdominal calculation package software (e.g., renal), an image recorder (e.g., videocassette), and a printer. Abdominal ultrasonic systems usually include linear array and mechanical and/or electronic sector scanning configurations. These systems are used for abdominal examination (e.g., cysts, tumors) and diagnoses (e.g., hernias).
