20110081057 | APPARATUS FOR STENOSIS ESTIMATION - Digital Subtraction Angiography (DSA) is widely used in the diagnosis and treatment of coronary arterial diseases such as arterial stenosis. However, the application of DSA for the assessment of stenosis severity is limited by the high intraobserver and interobserver variabilities associated with the visual assessment of stenosis severity from a cineangiogram (e.g., a sequential series of images after injection of a contrast media). The advent of Quantitative coronary angiography (QCA) has significantly reduced this limitation. | 04-07-2011 |
20100004530 | APPARATUS AND METHOD FOR POSITION SENSING - An improved apparatus and method for position sensing of a medical tracker device are presented. The apparatus and method are designed to constrain, rotate, and track the position of a medical tool. o improve the position sensing of the tracker, a joint that provides two degrees of freedom may use a revolute gear pair together with a rotary sensor for angular motion sensing and a sliding/prismatic assembly together with a linear magnetic sensor for linear position sensing. Thus, the linear motion sensing and the angular motion sensing are decoupled. | 01-07-2010 |
20100001996 | APPARATUS FOR GUIDING TOWARDS TARGETS DURING MOTION USING GPU PROCESSING - A method and apparatus using a graphics processing unit (GPU) are disclosed for three-dimensional (3D) imaging and continuously updating organ shape and internal points for guiding targets during motion. It is suitable for image-guided surgery or operations because the speed of guidance is achieved close to video rate. The system incorporates different methods of rigid and non-rigid registration using the parallelism of GPU processing that allows continuous updates in substantially real-time. | 01-07-2010 |
20090326363 | FUSED IMAGE MODALITIES GUIDANCE - An improved system and method (i.e. utility) for registration of medical images is provided. The utility registers a previously obtained volume onto an ultrasound volume during an ultrasound procedure to produce a multimodal image. The multimodal image may be used to guide a medical procedure, In one arrangement, the multimodal image includes MRI and/or MRSI information presented in the framework of a TRUS image during a TRUS procedure. | 12-31-2009 |
20090324041 | APPARATUS FOR REAL-TIME 3D BIOPSY - A method and apparatus are disclosed for performing software guided prostate biopsy to extract cancerous tissue. The method significantly improves on the current system by accelerating all computations using a graphical processing unit (GPU) keeping the accuracy of biopsy target locations within tolerance. The result is the computation of target locations to guide biopsy using statistical priors of cancers from a large population, as well as based on previous biopsy locations for the same patient, and finally via mapping protocols with predefined needle configurations onto the patient's current ultrasound image. | 12-31-2009 |
