Patent number: 8700126Abstract: Certain embodiments of the present invention provide systems and methods for detecting septal defects. In an embodiment, the method may include acquiring gated MRI data and heart atlas data. A registration of the gated MRI data and the heart atlas data may be performed as well as a flow-balance measurement. An atrial septal detection and ventricular septal detection may be performed, as well as a septal measurement. A diagnostic report may be generated detailing the location and properties of the septal defects. A physician may utilize the diagnostic report for surgery planning. After surgery, the diagnostic report may be compared with a post-surgery diagnostic report to determine the success of the surgery.Type: GrantFiled: January 11, 2007Date of Patent: April 15, 2014Assignee: General Electric CompanyInventors: Shou Li, Sukhdeep Gill, Prakash Mahesh, Dave Roeder

Patent number: 8639060Abstract: Certain embodiments of the present invention provide a system and method for temporally aligning a plurality of cardiac image sequences. The method includes performing a locally linear embedding algorithm on a first set of cardiac image sequences and on a second set of cardiac image sequences. A graphical representation is created for the first set of cardiac image sequences and the second set of cardiac image sequences. A determination is made whether the first set of cardiac image sequences and the second set of cardiac image sequences were generated from a similar point of view. If a similar point of view is found, the first graphical representation and the second graphical representation are aligned using a minimization function. If a similar point of view is not found, the graphs are aligned with a template and then aligned with each other using the minimization function.Type: GrantFiled: March 15, 2012Date of Patent: January 28, 2014Assignee: General Electric CompanyInventors: Shuo Li, Prakash Mahesh, Dave Roeder, Richard Rankin

Patent number: 8224052Abstract: Certain embodiments of the present technology provide systems, methods and computer instructions for computer aided analysis of images. In certain embodiments, for example, such a method includes: isolating a motion area in an image; segmenting the image; utilizing a support vector machine to identify a region of interest in the image; utilizing a graph-cut algorithm to refine the region of interest; and verifying the region of interest. In certain embodiments, for example, such a method further includes: aligning a set of images and/or outputting a set of aligned images sequentially. In certain embodiments, the systems, methods and computer instructions disclosed herein can be used to aid analysis of cardiac images, for example. In certain embodiments, the systems, methods and computer instructions disclosed herein can be used to aid analysis of four dimensional images, for example.Type: GrantFiled: January 11, 2012Date of Patent: July 17, 2012Assignee: General Electric CompanyInventors: Prakash Mahesh, Shuo Li, Dave Roeder, Ian Ross

Patent number: 8009886Abstract: Certain embodiments of the present invention provide for a system and method for performing medical image registration. Pixel and voxel correspondences are formulated as energy minimization problems and are optimized with graph cuts. The method includes processing a first set of data and a second set of data using a graph cuts algorithm to determine a minimum value of an energy function. The energy function has a data term and a smoothness term. The method also includes performing registration for the first set of data and the second set of data based on the data term and the smoothness term of the energy function. The system includes a computer system for performing medical image registration. The computer system comprises a processor and a memory in communication with the processor. The memory includes program code executable by the processor for executing a medical image registration algorithm.Type: GrantFiled: January 3, 2008Date of Patent: August 30, 2011Assignee: General Electric CompanyInventors: Shou Li, Prakash Mahesh, Dave Roeder, Greg Garvin
