Patent number: 12280274Abstract: A method of calibrating a monitoring system (10,14) is described in which a calibration phantom (70) is located with its center located approximately at the isocenter of a treatment room through which a treatment apparatus (16) is arranged to direct radiation, wherein the surface of the calibration phantom (70) closest to an image capture device (72) of the monitoring system (10,14) is inclined approximately 45° relative to the camera plane of an image capture device of the monitoring system. Images of the calibration phantom (70) are then captured using the image capture device (72) and the images are processed to generate a model of the imaged surface of the calibration phantom.Type: GrantFiled: April 19, 2024Date of Patent: April 22, 2025Assignee: VISION RT LIMITEDInventors: Edward William Mead, Ivan Daniel Meir

Publication number: 20250114118Abstract: A tissue-removing catheter for removing tissue in a body lumen includes an elongate body and a tissue-removing element mounted on a distal end portion of the elongate body. The tissue-removing element is configured to remove the tissue as the tissue-removing element is rotated by the elongate body within the body lumen. An inner liner is received within the elongate body. The inner liner defines a guidewire lumen. The inner liner isolates an interior of the guidewire lumen from the elongate body and tissue-removing element such that rotational forces are not transferred from the elongate body and tissue-removing element to the interior of the guidewire lumen when the elongate body and tissue-removing element are rotated during removal of tissue from the body lumen.Type: ApplicationFiled: October 14, 2024Publication date: April 10, 2025Inventors: Aram Jamous, John Kelly, Matthew William Fleming, Colin William Meade, Grainne Teresa Carroll

Publication number: 20240216716Abstract: Some embodiments are directed to an image director of a patient monitoring system to obtain calibration images of a calibration sheet or other calibration object at various orientations and locations. The images are then stored and processed to calculate camera parameters defining the location and orientation of the image detector and identifying internal characteristics of the image detector, and the information are stored. The patient monitoring system can be re-calibrated by using the image detector to obtain an additional image of a calibration sheet or calibration object. The additional image and the stored camera parameters are then used to detect any apparent change in the internal characteristics of the image detector (10)(S6-4).Type: ApplicationFiled: March 20, 2024Publication date: July 4, 2024Applicant: VISION RT LIMITEDInventors: Edward William MEAD, Ivan Daniel MEIR
