Abstract: A device, system, and method for volumetric ultrasound imaging is described. The device and system include an array of transducer elements grouped in triangular planar facets and substantially configured in the shape of a hemisphere to form a cup-shaped volumetric imaging region within the cavity of the hemisphere. A plurality of data-acquisition assemblies are connected to the transducers, which are configured to collect ultrasound signals received from the transducers and transmit image data to a network of processors that are configured to construct a volumetric image of an object within the imaging region based on the image data received from the data-acquisition assemblies. A control module includes a firmware module, a low-level operating-system device driver and an application programming interface library for processes ultrasound signals transmitted and received from the array of transducer elements.

Abstract: Periodic displacement occurs in body tissue due to heartbeat. A peak level D of the movement distance of the body tissue is detected (Step 21), and a heartbeat cycle T is calculated from a frequency spectrum (Steps 22 and 23). By dividing twice the peak level D by the heartbeat cycle T, the moving velocity of the body tissue in a unit heartbeat cycle is calculated (Step 24). By dividing the moving velocity by a frame rate r, an average movement distance of the body tissue between frames is calculated (Step 25). In a case where the average movement distance is smaller than a predetermined threshold value, a time interval between the frames used for the calculation of the movement distance is extended (being Step 26 NO, Step 27).

Abstract: HIFU (High-Intensity Focused Ultrasound) sometimes FUS or MIFUS is a highly precise medical procedure using high-intensity focused ultrasound to heat and destroy pathogenic tissue rapidly in the brain for neurosurgical purposes, by causing coagulation necrosis. Here we have described a system that uses specially designed micro-transducer heads that are placed inside the later ventricles for the purposes of MIFUS lesioning of brain targets under real time MRI, endoscopic and Doppler guidance. A minimally invasive approach using Kocher's point allows small incisions with little bleeding, recovery time, infection risk and surgical time. This approach allows insertion of the micro-ultrasound transducers into the lateral ventricles of the brain avoiding skull bone attenuation of the ultrasonic waves and unnecessary heating of brain tissues in the process.

Abstract: An anatomical structure is detected (110) in a volume of ultrasound data by identifying (150) the anatomical structure in another volume of ultrasound data and generating (155) an image of the anatomical structure and an anatomical landmark. A group of images are generated (130) of the original volume and compared (140) to the image of the other volume. An image of the group of images is selected (150) as including the anatomical structure based on the comparison.

Abstract: The invention relates to a temperature distribution determining apparatus for determining a temperature distribution within an object caused by applying energy to the object. A temperature distribution measuring unit (6, 7) measures a spatially and temporally dependent first temperature distribution in the object (3), while the energy is applied to the object (3) such that the object (3) is heated to a temperature within a first temperature range, and a temperature distribution estimating unit (5) estimates a spatially and temporally dependent second temperature distribution in the object (3) within a second temperature range, which is different to the first temperature range, based on the spatial and temporal dependence of the measured first temperature distribution. Since temperature distributions can be obtained not only in the first temperature range, but also in the second temperature range, the overall temperature range, in which the temperature distribution can be determined, can be increased.

Abstract: A computer implemented method, a computerized system and a computer program product for automatic image segmentation. The computer implemented method comprises obtaining an image of a tissue, wherein the image is produced using an imaging modality. The method further comprises automatically identifying, by a processor, a tissue segment within the image, wherein said identifying comprises identifying an artifact within the image, wherein the artifact is a misrepresentation of a tissue structure, wherein the misrepresentation is associated with the imaging modality; and searching for the tissue segment in a location adjacent to the artifact.
