Abstract: An interactive 3D cursor facilitates selection and manipulation of a three-dimensional volume from a three-dimensional image. The selected volume image may be transparency-adjusted and filtered to remove selected tissues from view. Qualitative and quantitative analysis of tissues in a selected volume may be performed. Location indicators, annotations, and registration markers may be overlaid on selected volume images.

Abstract: A method and apparatus for improvement of spatial resolution in molecular and radiological imaging is presented. System equipment includes bed with either flat or cylindrical detectors large detector arrays with collimator(s), lens(s), mirror(s) and/or shutter(s). This system utilizes magnification principles with large detector arrays. There is error reduction by reduction of non-collinearity error as seen in current PET scans by determination of the trajectory of the photons and accurate localization of the annihilation event of a positron. Additional error reduction of random coincidence and scatter coincidence is seen. Overall, this method and apparatus affords improved spatial resolution and higher efficiencies, which would allow for lower cost and dose reduction to the patient.

Abstract: Systems and a method for improved 3D visualization on a head display unit are presented herein. Exemplary features include filtering of the volume of interest and viewing the filtered volume of interest via a head display unit with a left eye display and a right eye display. Additional options include zooming and rotating. These features at least improve display of the 3D images to a user.

Abstract: An intra-cardiac device component (ICDC) is inserted into one to four chambers of the heart. The ICDC in the right atrium and left atrium expands while the tricuspid and mitral valves are open during the first-time epoch. The expansion in the right atrium and left atrium pushes blood from these atriums into their respective ventricles. The ICDC in the right ventricle and left ventricle contracts at this time epoch and the pulmonary and aortic valves are closed. In the succeeding time epoch, the ICDC in the right atrium and left atrium contracts while the tricuspid and mitral valves are closed, and the right atrium and left atrium are filling with blood. The ICDC in the right ventricle and left ventricle expand in this time epoch while the pulmonary and aortic valves are open. This sequence increases blood flow into the pulmonary artery and aorta and helps to remedy the decreased ability to pump blood in heart failure patients.

Abstract: A simulation is performed by assigning tissue type properties to voxels of a medical image and manipulating the voxels based on the assigned tissue type properties and an input that prompts voxel manipulation. Voxels may also be created and eliminated in response to the input. Tissue type properties may include elasticity, ductility, hardness, density, and thermal conductivity. Manipulation may include changing at least one of voxel size, location, orientation, shape, color, grayscale, and tissue type property value. The input may include insertion of a virtual volume-subtending surgical or anatomic object. Simulations may include virtual motion, deformation of tissue, and radiological dissection for pre-operative planning.

Abstract: An interactive placement of a digital representation of a surgical device or anatomic feature into a radiologic 3D medical image that contains a feature of interest is described. Integration of the digital representation of the surgical device or anatomic feature with the radiologic 3D medical image facilitates pre-operative surgical planning and surgical device selection. Location indicators, annotations, and registration markers may be overlaid on selected volume images.

Abstract: A 3D image processing system includes voxel adjustments based on radiodensity, filtering and segmentation, each of which may be selected, configured, and applied in response to controller-entered commands. Voxel adjustments based on radiodensity may include changes to grayscale values and color, e.g. to enhance selected tissues or to emphasize differences between tissues of similar radiodensity. Voxel adjustments based on radiodensity may include demarcation, and changes to voxel size, shape, and orientation. Filtering may include removing a portion of voxels of a selected radiodensity from a presented image. Segmentation may characterize voxels based on nearest neighbors, and grow features or fill gaps. Multiple images may be generated with different configuration settings and be combined into a composite image.

System equipment includes bed with either flat or cylindrical detectors large detector arrays with collimator(s), lens(s), mirror(s) and/or shutter(s). This system utilizes magnification principles with large detector arrays. There is error reduction by reduction of non-collinearity error as seen in current PET scans by determination of the trajectory of the photons and accurate localization of the annihilation event of a positron. Additional error reduction of random coincidence and scatter coincidence is seen. Overall, this method and apparatus affords improved spatial resolution and higher efficiencies, which would allow for lower cost and dose reduction to the patient.
