Abstract
An apparatus/method for measuring the volume of urine in a human bladder, including a scanhead and transceiver for transmitting a plurality of ultrasound signals (10, 24) into the bladder and for receiving the returning ultrasound signals (10,24). The apparatus further includes a signal processor for automatically processing the received signals (26), a digitizer for converting the analog signal into a series of digital data elements (28) and a CPU and signal processing software for processing the data elements (12,34) so as to determine the distance between the front and rear of the bladder or the area of the plane of the ultrasound signals, and for computing the volume of the bladder and hence the volume of urine in the bladder from the distance or area information (12, 34).
