Patent number: 9848835Abstract: In one embodiment of the invention, a method for obtaining a tomogram of an anatomical structure is disclosed. In one step, an anatomical structure is scanned using a scanning source and a scanning detector. Both the scanning source and detector are connected to a gantry. In another step, the speed of the gantry is altered during the scanning process. Additionally or optionally the frame rate of the scan can be modified in such step. In a particular embodiment of the invention, the speed of the gantry is altered in synchronicity with the respiratory signal of a patient. Using such a method, a tomogram of an anatomical structure is obtained.Type: GrantFiled: August 16, 2010Date of Patent: December 26, 2017Assignee: Varian Medical Systems International AGInventors: Timo Berkus, Xiu Ting Zhuang, Andres Graf, Markus Oelhafen, Patrik Kunz

Patent number: 9579526Abstract: Embodiments of the claimed subject matter provide a radiation therapy system for the acquisition of volumetric imaging with advanced trajectories. Embodiments include a device for applying diagnostic and therapeutic radiation to a target volume disposed in a patient subject, wherein volumetric imaging is acquired with advanced trajectories without displacing the patient subject. In one embodiment, a radiation therapy device is provided comprising: a gantry with a radiation source and a plurality of independent robotic arms mounted to the gantry, wherein an X-ray source is attached to an end of one robotic arm; and an imager attached to an end of another second robotic arm.Type: GrantFiled: February 2, 2009Date of Patent: February 28, 2017Assignee: Varian Medical Systems International AGInventors: Patrik Kunz, Timo Berkus, Markus Oelhafen, Reto Filiberti

Patent number: 8983161Abstract: A method for correcting a volumetric image to address error due to deflection of a patient support is provided. The method includes obtaining a first set of projection data and a second set of projection data. The first and second sets of projection data are generated when the patient is at a first position and a second position, respectively, and are usable to reconstruct a first volumetric image and a second volumetric image, respectively. A corrected volumetric image is then determined based on the first and second sets of projection data.Type: GrantFiled: November 9, 2011Date of Patent: March 17, 2015Assignee: Varian Medical Systems International AGInventors: Timo Berkus, Katharina Quintus, Markus Oelhanfen, Patrik Kunz

Patent number: 8938104Abstract: A system for obtaining an image includes a processor for receiving a projection image, processing the projection image to obtain a filtered image, applying a first factor for the projection image to obtain a first weighted image, applying a second factor for the filtered image to obtain a second weighted image, and obtaining a corrected image using the first and second weighted images, and a medium for storing the corrected image. A method of processing an image includes receiving a projection image, processing the projection image to obtain a filtered image, and determining a corrected image by applying a first factor for the projection image and applying a second factor for the filtered image. A method for obtaining an image includes determining a factor, using the factor to control a radiation source, and using the factor to reduce noise in an image generated using the radiation source.Type: GrantFiled: August 29, 2008Date of Patent: January 20, 2015Assignee: Varian Medical Systems International AGInventors: Timo Berkus, Patrik Kunz, Markus Oelhafen, Marc Kachelrieβ
