摘要： 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. To 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.

摘要： An image guidance system is provided for improving tissue culture extraction where the tissue is extracted under the guidance of first and second knowledge-based systems. The first knowledge-based system provides initial suggested regions of interest for tissue biopsy in an internal organ. These regions of interest are then confirmed as being of interest of being benign by the second knowledge-based system. Information from two different sources may provide a more accurate, intelligent and robust method that helps in selecting biopsy sites accurately, such that suspicious regions are not overlooked and the benign regions are not unnecessarily operated upon. This not only helps in better diagnosis and treatment, but also helps reduce pain to the patient, in addition to reducing wastage of resources and invaluable time.

摘要： Systems and method are provided for registering medical images to reduce movement between the images. In one arrangement, a hierarchical image registration is performed where regions of the largest differences between images are identified and utilized to drive the deformation of one of the images. Such regions are identified in one arrangement by determining intensities and gradient magnitudes for corresponding regions of the images. In another arrangement, a multi-resolution registration strategy is applied.

摘要： Provided herein are improved biopsy systems and methods (i.e., utilities), which among other benefits, assist physicians with the selection biopsy sites based on temporally distinct images. More generally, the utilities allow for registering medical images such that information associated with a medical image obtained at a first time may be mapped to a subsequent medical image obtained at a subsequent time. This may result in improved diagnosis, better planning, better treatment delivery and/or follow-up.

摘要： Provided herein are devices and methods for mounting variously configured medical imaging probes to a tracker assembly for imaging applications. In one aspect, a tracker assembly provides multiple degrees of freedom for positioning a probe relative to a patient and/or maintaining a probe in a desired location for imaging purposes. The tracker generates location information that may be utilized as frame of reference information for acquired images. In another aspect a holding device allows for interfacing/holding differently configured probes in a common orientation to a predetermined frame of reference.

摘要： Guided biopsy is a commonly used method to remove suspicious tissues from an internal organ for pathological tests so that malignancy can be established. Provided herein are systems and methods (i.e., utilities) that allow for automated application of one or more predefined biopsy target plans to an acquired medical image including without limitation, an ultrasound prostate image. Due to different shapes and sizes of prostates as well as orientation of prostate with respect to an ultrasound probe during image, acquisition a simple prostate model (e.g., ellipse) with a fixed plan may not be sufficient. Accordingly, it has been determined that a deformable shape model with integrated biopsy target locations/sites may be fit to a prostate image to provide improved automated biopsy targeting.
