Patent number: 9373167Abstract: A machine-implemented display method that, with respect to a volume dataset being rendered, enables a user to navigate to any position in space and look in any direction. Preferably, the volume dataset is derived from a computer tomography (CT) or magnetic resonance imaging (MRI) scan. With the described approach, the user can see details within the dataset that are not available using conventional visualization approaches. The freedom-of-motion capability allows the user to go to places (positions) within the volume rendering that are not otherwise possible using conventional “orbit” and “zoom” display techniques. Thus, for example, using the described approach, the display image enables a user to travel inside physical structures (e.g., a patient's heart, brain, arteries, and the like). In this approach, a display image includes information visually representing an amount of difference between a current pixel and its neighbor pixels.Type: GrantFiled: October 15, 2013Date of Patent: June 21, 2016Assignee: Intrinsic Medical Imaging, LLCInventors: Lee R.

Patent number: 9342920Abstract: A GPU-based cloud computing platform is used to facilitate data computations on behalf of requesting users. In this embodiment, a user of a thin client has an associated dataset that requires computation. That dataset is adapted to be delivered to a computing platform, such as the GPU-based cloud, for computation, such as to facilitate a 3D volume rendering. The result of the computation is then returned to the user. Multiple such users may be operating clients and requesting computations from the cloud in a similar manner, possibly concurrently.Type: GrantFiled: November 15, 2012Date of Patent: May 17, 2016Assignee: Intrinsic Medical Imaging, LLCInventors: Lee R. McKenzie, Mark C. McKenzie

Publication number: 20160098531Abstract: A method of assessing stenosis severity for a patient includes generating a three dimensional model of a lesion specific vessel tree of the patient. A plurality of inlet and outlet positions are identified in the lesion tree. A total flow rate from the vessel tree model is estimated. A processor and task specific software are utilized to perform computational fluid dynamic simulation on the vessel tree. A flow rate and apparent flow resistance for each of the outlets is then determined. At least one ideal model is generated. A computational fluid dynamic simulation is performed on the at least one ideal model. A level of stenosis severity is determined for each of the outlets.Type: ApplicationFiled: December 10, 2015Publication date: April 7, 2016Applicant: INTRINSIC MEDICAL IMAGING LLCInventors: Zhongle Wu, Jorey Chernett

Patent number: 9237849Abstract: A machine-implemented display method that, with respect to a volume dataset being rendered, enables a user to navigate to any position in space and look in any direction. An enhanced display method for this type of dataset improves upon known Maximum Intensity Projection (MIP) techniques. The enhanced method, “Relative MIP,” uses a different approach to pixel value rendering. Relative MIP draws information from an amount of difference present between a current pixel and its neighbors, and then visualizes the maximum intensity of this difference.Type: GrantFiled: May 23, 2013Date of Patent: January 19, 2016Assignee: Intrinsic Medical Imaging, LLCInventor: Lee R.

Publication number: 20160000397Abstract: A method of assessing stenosis severity for a patient includes obtaining patient information relevant to assessing severity of a stenosis, including anatomical imaging data of the patient. Based on the anatomical imaging data, the existence of any lesions of concerns may be identified. A three dimensional image can be generated of any irregular shaped lesion of concern and a surrounding area from the patient anatomical imaging data. A plurality of comparative two dimensional lesion specific models may be created that have conditions that correspond to the three dimensional model. The comparative two dimensional models may represent vessels having regular shaped lesions with each of the comparative two dimensional models represents a different stenosis severity. The three dimensional model can then be mapped to one of the plurality of comparative two dimensional models. After this mapping, a diagnosis of whether the patient has coronary artery disease may be made.Type: ApplicationFiled: March 10, 2015Publication date: January 7, 2016Applicant: INTRINSIC MEDICAL IMAGING LLCInventors: Zhongle Wu, James Jacobs
