Patent number: 8734349Abstract: A method (50) for quantitative 3D contrast enhanced ultrasound (CEUS) analysis includes acquiring (54) an initial pair of ultrasound contrast and tissue images of an anatomy. A region of interest (ROI) or volume of interest (VOI) is established (56) in the initial acquired tissue image, which becomes the baseline tissue image. The established ROI/VOI is automatically registered (58) from the initial tissue image to the initial contrast image, which becomes a baseline contrast image. Quantitative analysis is performed (60) on the ROI/VOI of the baseline contrast image. The method further includes acquiring (62) a next ultrasound contrast and tissue image pair, corresponding to an i th current contrast and tissue image pair.Type: GrantFiled: November 5, 2008Date of Patent: May 27, 2014Assignee: Koninklijke Philips N.V.Inventors: Jochen Kruecker, Sheng Xu

Publication number: 20130039555Abstract: A 3D ultrasound image from a memory (20) is compared with a 3D diagnostic image from a memory (12) by a localizer and registration unit (30) which determines a baseline transform (Tbase) which registers the 3D diagnostic and ultrasound volume images. The target region continues to be examined by an ultrasound scanner (22) which generates a series of real-time 2D or 3D ultrasound or other lower resolution images. The localizer and registration unit (30) compares one or a group of the 2D ultrasound images with the 3D ultrasound image to determine a motion correction transform (Tmotion). An image adjustment processor or program (32) operates on the 3D diagnostic volume image with the baseline transform (Tbase) and the motion correction transform (Tmotion), to generate a motion corrected image that is displayed on an appropriate display (74).Type: ApplicationFiled: October 20, 2008Publication date: February 14, 2013Inventors: Sheng Xu, Jochen Kruecker, Luis Felipe Gutierrez

Patent number: 8267927Abstract: In planning an ablation procedure, a planned target volume (PTV) is imported, which is typically selected by a doctor but may be computer-identified. An ablation solution comprising a plurality of ablation volumes is generated or selected using a lookup table. Ablations sharing a common axis along a line of insertion are grouped into blocks. Alternatively, the PTV is enveloped in a sphere, and a pre-computed ablation solution (e.g., a 6- or 14-sphere solution) is identified to cover the PTV sphere. Optionally, a mathematical algorithm is executed to increase an axis through the ablation spheres to generate ellipsoidal ablation volumes that envelop the PTV.Type: GrantFiled: February 22, 2010Date of Patent: September 18, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Sandeep Dalal, Karen Irene Trovato, Jurgen Jan Rusch, Jochen Kruecker

Patent number: 7933007Abstract: An electro-magnetic tracking system includes a system controller having a sensor interface, a generator, and a positioning and angular orientation configuration. The generator is responsive to the system controller for generating an electro-magnetic field that includes a tracking volume of highest accuracy. The highest accuracy corresponds to an accuracy of the sensor interface and system controller to detect a sensor physically located within the tracking volume versus a lesser accuracy of the sensor interface and system controller to detect the sensor if the sensor is located outside of the tracking volume. The positioning and angular orientation configuration is coupled to the field generator for visibly optimizing (i) a positioning and/or (ii) an angular orientation of the electro-magnetic field generator such that the tracking volume lies within a centroid of a physical volume of interest, thereby enabling a detection of a sensor within the tracking volume with a highest accuracy.Type: GrantFiled: December 8, 2006Date of Patent: April 26, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Douglas Stanton, Jochen Kruecker

Publication number: 20100249595Abstract: A system and method of tracking ultrasound transducers or probes (12) with spatial localizers (16) achieves automatic calibration with a minimum addition of hardware to that required by earlier systems. An image-based tracking algorithm localizes control points in an image space (I). An unlimited number of points can then be used for ultrasound calibration, allowing for high calibration accuracy. The proposed calibration system (10) is simple and low cost. The calibration is fast and can be carried out automatically.Type: ApplicationFiled: November 5, 2008Publication date: September 30, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Sheng Xu, Jochen Kruecker
