1. A method to determine bladder wall thickness using an ultrasound transceiver, the method comprising:
- positioning an ultrasound transceiver exterior to a patient such that at least a portion of the bladder wall is within the range of the transceiver;
transmitting radio frequency ultrasound pulses to, and receiving those pulses echoed back from, the external and internal surface of the portion of the bladder wall; and
, based on those pulses calculating for the portion of the bladder wall (a) the surface area of the external and internal surfaces, and (b) the distance between the external and internal surfaces.

Abstract
An ultrasound transceiver scans a bladder in a three dimensional array to measure the thickness and surface area of the bladder to determine bladder mass. The bladder wall thickness and masses may be determined for anterior, posterior, and lateral locations of the bladder.

20. A system for determining the mass of an internal organ, the system comprising:
-
a transceiver configured to deliver radio frequency ultrasound pulses in a plurality of scanplanes to the organ of a patient, receive echoes of the pulses reflected from the organ, and process the echoes into horizontal and vertical components; and
a computer system in communication with the transceiver, the computer system having a microprocessor and a memory, the memory further containing stored programming instructions operable by the microprocessor to determine the surface area, thickness, and mass of the organ based on the horizontal and vertical components of the echoes. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
