Patent number: 10010308Abstract: An image-guided system and method for performing needle biopsy on a moving lung nodule of a body is provided. CT images of the lung nodule are obtained to generate a motion model, based on which an optimal needle advancing path is determined. The motion of the lung nodule and the motion of a fiducial marker attached to the body are correlated. The motion of the fiducial marker is tracked and monitored by a camera to determine a position of the lung nodule based on the correlation. A time for advancing the needle is determined based on a motion attribute of the reference. The needle is advanced by a robotic needle manipulator at the predetermined time along the path to accomplish the needle placement.Type: GrantFiled: July 20, 2012Date of Patent: July 3, 2018Assignee: The Research Foundation for The State University of New YorkInventors: Yu Zhou, Kaarvannan Thiruvalluvan, Lukasz Krzeminski, William H.

Patent number: 10004425Abstract: A method of optimizing scan parameters for LGE-MRI. At least one cardiac MRI TI scout scan is performed by applying an inversion pulse every predetermined heartbeat of a patient. An initial value of an inversion time TIinitial is determined by assessing a set of images generated from the scout scan. A first multiple of a duration between successive indicia of ventricular depolarization is selected, and a relaxation time T1 is determined based on the initial value Tinitial and the first multiple of duration. An optimized inversion time TIoptimal for LGE-MRI is determined based on the relaxation time T1 and a second multiple of a duration between successive indicia of ventricular depolarization. A correction factor is determined based on the optimized inversion time TIoptimal from the initial value of the inversion time TIinitial.Type: GrantFiled: July 25, 2017Date of Patent: June 26, 2018Assignee: University of Utah Research FoundationInventors: Nassir F.

Patent number: 9924926Abstract: An ultrasonic diagnostic imaging system is operated to acquire an ultrasound image of a region of the body containing suspect anatomy such as a suspected lesion. A body marker template (104, 106) of the region of the body is displayed on a touchscreen display of the imaging system. The operator records the location of the suspect anatomy by touching a corresponding point on the body marker template displayed on the touchscreen display. The mark (120 a, 120 b) on the template can be finely adjusted by one or more controls on the imaging system control panel. The body marker template can also record a graphic indicating (120 c) the orientation of the ultrasound probe relative to the body when the suspect anatomy was imaged. A report generator produces a report containing both the ultrasound image of the suspect anatomy and the body marker template with the indicated location of the suspect anatomy.Type: GrantFiled: July 11, 2017Date of Patent: March 27, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Patty Jackson, Cedric Chenal
