Patent number: 10405834Abstract: An anatomical structure is segmented from images generated in an anatomical scan. A user input device is configured for manually identifying two or more seed points on a plurality of the images. An image processor is configured to identify an optimal path through seed points on the plurality of images with a graph search. The optimal path between corresponding seed points on different images defines a boundary contour, and the anatomical structure includes two or more boundary contour. The image processor is further configured to interpolate the boundary contours over a three-dimensional volume using cardinal splines.Type: GrantFiled: May 31, 2016Date of Patent: September 10, 2019Assignee: The Governors of the University of AlbertaInventors: Jacob Lester Jaremko, Abhilash Hareendranathan, Myles Mabee, Richard Thompson, Pierre Boulanger, Kumaradevan Punithakumar

Publication number: 20180368686Abstract: An apparatus and method for generating a fused scan image from a plurality of anatomical scan images of a patient. A tracking system is used to track the physical position and orientation of a scanner transducer, such as an ultrasound probe, which is used to obtain the anatomical scan images. The tracking system may also be used to track markers positioned on the patient for tracking anatomical movement of the patient. An image-processing based fusion is applied to the plurality of anatomical scan images based on the tracked position and orientation of the scanner transducer and the tracked patient anatomical movement to generate a fused scan image. The anatomical movement may comprise respiratory movement of the patient. An electrocardiogram (ECG) signal from the patient may be used to time synchronize tracking information generated by the tracking system with the plurality of anatomical scan images.Type: ApplicationFiled: December 14, 2016Publication date: December 27, 2018Inventors: Kumaradevan PUNITHAKUMAR, Harald BECHER, Pierre BOULANGER, Michelle NOGA, Abhilash Rakkunedeth HAREENDRANATHAN

Patent number: 9886546Abstract: Methods and apparatus are disclosed to label radiology images. An example system includes a processor and a database. In response to receiving a first user input via a data input, the processor is to generate first annotations on a spinal image. The processor is to cause the spinal image having the first annotations to be displayed at a user interface. The processor is to prompt a user to provide second user input identifying an error in the first annotations. In response to receiving the second user input, the processor is to generate second annotations on the spinal image. The second annotations is to correct the error in the first annotations.Type: GrantFiled: June 26, 2013Date of Patent: February 6, 2018Assignee: General Electric CompanyInventors: Ismail Ben Ayed, Dmitry Pavlov, Kumaradevan Punithakumar, Seyed-Parsa Hojjat, Gregory Garvin

Patent number: 9824456Abstract: A time series of image frames in an anatomical scan is segmented. An image frame k in the time series of image frames is manually segmented. A non-rigid registration is then performed between the image frame k and a next image frame k+1 in the time series of image frames. A segmentation on the image frame k+1 is computed based on the non-rigid registration. Each subsequent image frame k+n in the time series of image frames is iteratively segmented using non-rigid registration with the segmented previous image frame k+(n?1) in the time series of image frames.Type: GrantFiled: June 26, 2015Date of Patent: November 21, 2017Assignee: The Governors of the University of AlbertaInventors: Michelle Noga, Kumaradevan Punithakumar
