| 20080242985 | 3D ULTRASOUND-BASED INSTRUMENT FOR NON-INVASIVE MEASUREMENT OF AMNIOTIC FLUID VOLUME - A hand-held 3D ultrasound instrument is disclosed which is used to non-d invasively and automatically measure amniotic fluid volume in the uterus requiring a minimum of operator intervention. Using a 2D image-processing algorithm, the instrument gives automatic feedback to the user about where to acquire the 3D image set. The user acquires one or more 3D data sets covering all of the amniotic fluid in the uterus and this data is then processed using an optimized 3D algorithm to output the total amniotic fluid volume corrected for any fetal head brain volume contributions. | 10-02-2008 |
| 20080249414 | SYSTEM AND METHOD TO MEASURE CARDIAC EJECTION FRACTION - A system and method to acquire 3D ultrasound-based images during the end-systole and end-diastole time points of a cardiac cycle to allow determination of the change and percentage change in left ventricle volume at the time points. | 10-09-2008 |
| 20090112089 | SYSTEM AND METHOD FOR MEASURING BLADDER WALL THICKNESS AND PRESENTING A BLADDER VIRTUAL IMAGE - 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. | 04-30-2009 |
| 20100036252 | ULTRASOUND SYSTEM AND METHOD FOR MEASURING BLADDER WALL THICKNESS AND MASS - An ultrasound transceiver scans an organ and processes the echogenic signals to produce three-dimensional, two-dimensional, and one-dimensional information of the organ. The 3-D, 2-D, and 1-D information is utilized to determine the thickness, surface area, volume, and mass of the organ wall. | 02-11-2010 |
| 20100204581 | SYSTEMS AND METHODS FOR DETERMINING ORGAN WALL MASS BY THREE-DIMENSIONAL ULTRASOUND - 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. | 08-12-2010 |
| 20110004101 | SYSTEM AND METHOD TO IDENTIFY AND MEASURE ORGAN WALL BOUNDARIES - Systems and methods are described for acquiring, processing, and presenting boundaries of a cavity-tissue interface within a region-of-interest in an ultrasound image based upon the strength of signals of ultrasound echoes returning from structures within the region-of-interest. The segmentation of boundaries of cavity shapes occupying the region-of-interest utilizes cost function analysis of pixel sets occupying the cavity-tissue interface. The segmented shapes are further image processed to determine areas and volumes of the organ or structure containing the cavity within the region-of-interest. | 01-06-2011 |
