Patent number: 11950967Abstract: A system for planning and performing a repeat interventional procedure is provided which includes a registration device and an image generation device which map current targets in a reference image for a first interventional procedure to at least one guidance image acquired from a different imaging modality. Biopsy locations are recorded to the guidance images during the first interventional procedure and the biopsy locations are mapped to the reference image to provide a planning image for use in a subsequent interventional procedure on the patient. In a subsequent interventional procedure, the prior planning image (124) may be registered to a current reference image and the prior biopsy locations and prior and current targets are mapped to a guidance image acquired from a different imaging modality. Biopsy locations are then mapped to the guidance image and mapped back to the current reference image.Type: GrantFiled: May 25, 2021Date of Patent: April 9, 2024Assignees: KONINKLIJKE PHILIPS N.V., THE UNITED STATES of AMERICA, as Represented by the Secreatary, Dept. of Health and Human ServicesInventors: Jochen Kruecker, Pingkun Yan, Amir Mohammad Tahmasebi Maraghoosh, Peter A Pinto, Bradford Johns Wood

Patent number: 11766244Abstract: The present disclosure describes ultrasound systems and methods configured to determine the elasticity of a target tissue. Systems can include an ultrasound transducer configured to acquire echoes responsive to ultrasound pulses transmitted toward the tissue, which may include a region of increased stiffness. Systems can also include a beamformer configured to control the transducer to transmit a push pulse into the tissue, thereby generating a shear wave in the region of increased stiffness. The beamformer can be configured to control the transducer to emit tracking pulses adjacent to the push pulse. Systems can further include a processor configured to determine a displacement amplitude of the shear wave and based on the amplitude, generate a qualitative tissue elasticity map of the tissue. The processor can combine the qualitative map with a quantitative map of the same tissue, and based on the combination, determine a boundary of the region of increased stiffness.Type: GrantFiled: May 1, 2019Date of Patent: September 26, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Faik Can Meral, Shriram Sethuraman, William Tao Shi, Pingkun Yan, Jochen Kruecker

Publication number: 20200151882Abstract: The following relates generally to image segmentation. In one aspect, an image is received and preprocessed. The image may then be classified as segmentable if it is ready for segmentation; if not, it may be classified as not segmentable. Multiple, parallel segmentation processes may be performed on the image. The result of each segmentation process may be marked as a potential success (PS) or a potential failure (PF). The results of the individual segmentation processes may be evaluated in stages. An overall failure may be declared if a percentage of the segmentation processes marked as PF reaches a predetermined threshold.Type: ApplicationFiled: January 8, 2020Publication date: May 14, 2020Inventors: PINGKUN YAN, CHRISTOPHER STEPHEN HALL, KONGKUO LU
