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.
Claims36
A method to determine bladder wall mass, the method comprising:
- positioning an ultrasound transceiver exterior to a patient such that at least a portion of the bladder is within a field of view of the transceiver, the ultrasound transceiver configured to send radio frequency ultrasound pulses and to receive echoes of the radio frequency ultrasound pulses;
- sending the radio frequency ultrasound pulses from the ultrasound transceiver to a bladder wall surface;
- receiving echoes of the radio frequency ultrasound pulses reflected from the bladder wall surface;
- calculating the surface area of the bladder based on the received ultrasound echoes;
- calculating the thickness of at least a portion of the bladder wall based on the received ultrasound echoes;
- and
- calculating the mass of the bladder wall as a function of the calculated surface area and thickness.

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 and receive echoes of the pulses reflected from the organ;
- 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 of the organ and the thickness of the organ based on the echoes
- received by the transceiver, and further to calculate the mass of the organ as a function of organ thickness and area.
