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 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.

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: The presented invention aims to address these and/or additional issues by providing a tracked grid for brachytherapy applications that can adjust to changes in the prostate between original image acquisition. The grid is allowed to be moved around and even rotated under tracked conditions, such that it can be maneuvered to align with any target region. A virtual 3-D grid is displayed on a computer with respect to the actual anatomy of the patient. The tracked grid can be moved relative to the virtual 3-D grid, such that the brachytherapy, cryo therapy or any other type of image guided therapy may be performed in real 3-D or even 4-D, when motion compensation is embedded during the procedure.

摘要: Provided herein is a medical imaging system that allows for real-time guidance of, for example, catheters for use in interventional procedures. In one arrangement, an imaging system is provided that generate a series of images or frames during a dye injection procedure. The system is operative to automatically detect frames that include dye (bolus frames) and frames that are free of dye (mask frames). The series of images may be registered together to provide a common reference frame and thereby account for motion. Sets of mask frames and bolus frames are averaged together, respectively, to improve signal to noise qualities. A differential image is generated utilizing the average mask and average bolus frames. Contrast of the differential image may be enhanced. The system allows for motion correction, noise reduction and/or enhancement of a differential image in real time.

摘要: Presented are systems and methods that allow for interpolation of a 3-D volume from arbitrarily oriented 2-D medical images. The interpolation of 3-D volume from arbitrarily oriented 2-D images reduces or eliminates most constraints on image acquisition thereby allowing for, inter alia, freehand manipulation of an image acquisition device (e.g. an ultrasound transducer). Related utilities involve the use of prior information about a specific object of interest to interpolate a surface (e.g., 3-D surface) of the object from limited information obtained from very few 2-D images.
