Publication number: 20220241613Abstract: Devices and methods that allow a user to elect between performing treament planning by inverse planning or to be accomplished by utilizing one or more parameters input that are typically associated with forward planning are described herein. The systems can be configured to produce a treatment plan in a single iteration upon initiation of treatment planning or in response to determining or receiving a target geometry. While the system may be used iteratively in an extensively interactive fashion, viable inverse plans can be generated with a single user interaction, such as a single click, or optionally with no click at all. Advantageously, the system can optionally allows a clinnician to add or adjust parameters or constraints, for example in another iteration, to provide additional autonomy if desired.Type: ApplicationFiled: February 1, 2022Publication date: August 4, 2022Applicant: Zap Surgical Systems, Inc.Inventors: Radhika Mohan Bodduluri, Thibaut Loysel, Achim Schweikard, John R.

Patent number: 7260426Abstract: A method and apparatus for locating an internal target region during treatment without implanted fiducials is presented. The method comprises producing a plurality of first images that show an internal volume including the internal target region, then producing a live image of the internal volume during treatment and matching this live image to one of the plurality of first images. Since the first images show the internal target region, matching the live image to one of the first images identifies the position of the target region regardless of whether the second image itself shows the position of the target region. The first images may be any three-dimensional images such as CT scans, magnetic resonance imaging, and ultrasound. The live image may be, for example, an x-ray image. The invention may be used in conjunction with a real-time sensor to track the position of the target region on a real-time basis.Type: GrantFiled: November 12, 2002Date of Patent: August 21, 2007Assignee: Accuray IncorporatedInventors: Achim Schweikard, John R.

Patent number: 7167738Abstract: A method is described for navigating in the interior of the body using three-dimensionally visualized structures. In a first step of the method, at least two two-dimensional images of the same anatomical object are provided from different perspectives, and also items of information that make it possible to draw conclusions about the respective spatial position of an imaging system relative to the anatomical object. The projections of a geometrical structure to be visualized are then created in every two-dimensional image, wherein a geometrical structure to be visualized is created in each two-dimensional image, wherein the geometrical structure to be visualized is different from the anatomical object.Type: GrantFiled: July 31, 2001Date of Patent: January 23, 2007Assignee: Stryker Leibinger GmbH & Co., KGInventors: Achim Schweikard, Manfred Doetter, Michael Roth, José-Luis Moctezuma de la Barrera
