  • Patent number: 8016760
    Abstract: 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.

  • Patent number: 7998072
    Abstract: Methods, systems and probes communicate signals from a transducer for imaging or connection with an imaging system. Beamforming-related electronics are positioned in the connector housing of the transducer probe assembly. For example, analog-to-digital converters are positioned in the connector housing. Power is provided through connection with the ultrasound imaging system. Fans or other heat-dissipating structures are also positioned within the connector housing. Other beamformer electronics, such as delays and sums, are positioned in the imaging system, partly in the connector housing or entirely in the connector housing. Since the analog-to-digital converters are provided in the connector housing, partial digital beam forming may be provided in the transducer probe assembly. The length of the transducer cables is held constant to avoid interference and transmission line effects due to line-length variation.

  • Patent number: 7983733
    Abstract: A system for controlling a medical device in a patient. A display system displays an image of a volume of the patient in a virtual three-dimensional space. A stylus is controllable to actuate a virtual element in the virtual space. A navigation system controls the medical device in the patient volume based on a position of the actuated virtual element. This inherently three-dimensional interface allows a physician to actuate the medical device more intuitively than possible using a two-dimensional interface.

  • Patent number: 7937132
    Abstract: This invention discloses a method and apparatus to deliver medical devices to targeted locations within human tissues using imaging data. The method enables the target location to be obtained from one imaging system, followed by the use of a second imaging system to verify the final position of the device. In particular, the invention discloses a method based on the initial identification of tissue targets using MR imaging, followed by the use of ultrasound imaging to verify and monitor accurate needle positioning. The invention can be used for acquiring biopsy samples to determine the grade and stage of cancer in various tissues including the brain, breast, abdomen, spine, liver, and kidney. The method is also useful for delivery of markers to a specific site to facilitate surgical removal of diseased tissue, or for the targeted delivery of applicators that destroy diseased tissues in-situ.

  • Patent number: 7914454
    Abstract: A method and apparatus for electronic volume data acquisition using ultrasound generates image data in a scanning and imaging process known as coherent aperture combining beamforming (CAC-BF). The CAC-BF technique can be applied in an azimuth dimension and/or an elevation dimension, to form an ultrasound image line, image plane, or image data cube. Several innovations relating to the design and ordering of shots and efficient weighting algorithms that address various performance issues associated with B-mode and other modes such as Doppler, and harmonic imaging are disclosed. The invention has significant advantages over other synthetic aperture imaging techniques and conventional imaging techniques by supporting higher resolution, larger volumes and/or shorter acquisition times than comparative techniques, using similar system hardware complexity.

A processor is provided with a three-dimensional imaging algorithm and a three-dimensional image segmentation algorithm for at least the specific organs within the anatomical portion and the needles. The processor converts the image data into a three-dimensional image of the anatomical portion using at least one single or multi-objective anatomy based genetic optimization algorithm. The processor determines in real time the optimal number and position of the hollow needles, the position of the energy emitting source within each hollow needle and the dwell times of the energy emitting source at each position. For post planning purposes, the processor determines, based on three-dimensional image information in real time, the real needle positions and the dwell times of the energy emitting source for each position.
