Patent number: 8221321Abstract: Ultrasound imaging systems and methods are disclosed. In one embodiment, an ultrasonography method includes creating a database that is representative of a tissue, a fluid, or a cavity of a body, and transmitting ultrasound pulses into a region-of-interest in a patient. Echoes are received from the region of interest, and based upon the received echoes, compiling an ultrasonic pattern of the region-of-interest is compiled. The pattern is processed by comparing the region-of-interest patterns to the pattern information stored in the database. A composition within the region-of-interest of the patient is then determined.Type: GrantFiled: August 26, 2005Date of Patent: July 17, 2012Assignee: Verathon Inc.Inventors: Gerald McMorrow, Vikram Chalana, Jongtae Yuk, Henri Baartmans, Nicolaas Bom, Charles Theodoor Lancee, Egon J.

Patent number: 8016760Abstract: An ultrasound system and method to measure an organ wall weight and mass. When the organ is a bladder, a bladder weight (UEBW) is determined using three-dimensional ultrasound imaging that is acquired using a hand-held or machine controlled ultrasound transceiver. The infravesical region of the bladder is delineated on this 3D data set to enable the calculation of urine volume and the bladder surface area. The outer anterior wall of the bladder is delineated to enable the calculation of the bladder wall thickness (BWT). The UEBW is calculated as a product of the bladder surface area, the bladder wall thickness, and the bladder wall specific gravity.Type: GrantFiled: April 21, 2010Date of Patent: September 13, 2011Assignee: Verathon, Inc.Inventors: Vikram Chalana, Stephen Dudycha, Jongtae Yuk, Gerald McMorrow
