Patent number: 11501451Abstract: Presented are concepts for detecting subject motion in medical imaging of a subject. One such concept obtains a motion classification model representing relationships between motion of image features and subject motion values. For each of a plurality of medical slice images of an imaged volume of the subject, an image feature of the medical slice image is extracted. Based on the extracted image feature for each of the plurality of medical slice images, motion information for the image feature is determined. Based on the motion information for the image feature and the obtained motion classification model, a subject motion value is determined.Type: GrantFiled: July 11, 2019Date of Patent: November 15, 2022Assignee: Koninklijke Philips N.V.Inventors: Dinesh Mysore Siddu, Krishnamoorthy Palanisamy, Christopher Stephen Hall, Nagaraju Bussa

Patent number: 8447081Abstract: A method for automatically detecting pulmonary embolism (PE) candidates within medical image data using an image processing device includes administering radiocontrast into a patient. A sequence of computed tomography (CT) images is acquired. A level of radiocontrast at a pulmonary artery trunk of the patient is determined. One or more PE candidates are detected within a pulmonary artery tree of the patient based on the determined level of radiocontrast at the pulmonary artery trunk. The one or more detected PE candidates are displayed.Type: GrantFiled: October 14, 2009Date of Patent: May 21, 2013Assignees: Siemens Medical Solutions USA, Inc., Siemens Information Systems, Ltd.Inventors: Sarang Lakare, Dinesh Mysore Siddu

Patent number: 8090178Abstract: A medical imaging system is used to recognize an internal structure from a three-dimensional image. The image includes image sub-volumes. An image sub-volume is selected using a non-linear search pattern. The selected image sub-volume is analyzed for the presence of the internal structure. The steps of selecting an image sub-volume using the non-linear search pattern and analyzing the selected sub-volume for the presence of the internal structure are repeated until the internal structure is found in an image sub-volume. Bounds of the internal structure are identified based on the location of the image sub-volume within which the internal structure is found.Type: GrantFiled: March 30, 2007Date of Patent: January 3, 2012Assignee: Siemens Medical Solutions USA, Inc.Inventors: Dinesh Mysore Siddu, Mausumi Acharyya, Jonathan Stoeckel
