20090316975 | ANATOMIC ORIENTATION IN MEDICAL IMAGES - A method of constructing a navigation table relating a set of images representative of a region of interest in a subject to a reference system with reference positions indicating known anatomic landmarks of a reference subject comprising providing reference positions for two or more images identified with two or more anatomic landmarks indicative of the region of interest with reference positions of known anatomic landmarks corresponding to the identified anatomic landmarks, and determining reference positions for the remaining images by interpolation. | 12-24-2009 |
20100054562 | SYSTEMS AND METHODS FOR ADAPTIVE FILTERING - 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. | 03-04-2010 |
20100195792 | RADIATION THERAPY DEVICE WITH FREELY CUSTOMIZABLE SOURCE AND IMAGER MOTION TRAJECTORY - 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. | 08-05-2010 |
20110080990 | SYSTEMS AND METHODS FOR OBTAINING RECONSTRUCTED IMAGES DURING A TREATMENT SESSION - A medical system includes a treatment radiation source configured to deliver treatment radiation during a treatment session, an imaging system configured to obtain image data during the treatment session, and a processor configured to determine a beam break, and automatically operate the imaging system to obtain the image data during the beam break. A medical system includes a treatment radiation source, an imaging system configured to automatically obtain image data in a beam break that occurs during a treatment session, and a processor configured to automatically operate the treatment radiation source to deliver treatment radiation during the treatment session after the beam break ends. | 04-07-2011 |
20120039433 | VARIABLE-SPEED COMPUTED TOMOGRAPHY SCANNING - 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. | 02-16-2012 |
20120041773 | COMPUTERIZED SYSTEM FOR ADAPTIVE RADIATION THERAPY - In one embodiment of the invention, a computerized method for producing a treatment decision for adaptive radiation therapy (ART) is disclosed. The method comprises several steps. First, patient specific input data regarding a patient and general patient population data are input into a treatment decision engine. Next, this data is analyzed in order to adjust a set of interrelationships and thresholds to fit the ART regimen for which a decision is being processed. In a third step, the interrelationships and thresholds are applied to the data using a processing module which formulates a decision regarding the current ART regimen, and metadata regarding the medical condition of the patient. Finally, the decision and metadata are outputted such that they are accessible to a user. Using such a method, a treatment decision for ART is produced. | 02-16-2012 |
20130114871 | AUTOMATIC CORRECTION METHOD OF COUCH-BENDING IN SEQUENCE CBCT RECONSTRUCTION - An imaging method includes obtaining a first set of projection data when a patient support is at a first position, wherein the first set of projection data is usable to reconstruct a first volumetric image, obtaining a second set of projection data when the patient support is at a second position, wherein the second set of projection data is usable to reconstruct a second volumetric image, and determining a corrected volumetric image using the first set of projection data and the second set of projection data to correct for deflection of the patient support. In some embodiments, the method may involve obtaining additional set(s) of projection data. | 05-09-2013 |
20130251099 | METHOD AND SYSTEM FOR AUTOMATIC PATIENT IDENTIFICATION - In a method of verifying patient identity, an image of an individual who is to receive radiotherapy is obtained and compared with a reference image of a patient to whom the radiotherapy is intended. Confirmation or negation of the individual to be the patient intended can be made based on the comparison of the image of the individual with the reference image of the patient. | 09-26-2013 |
20130259338 | 4D CONE BEAM CT USING DEFORMABLE REGISTRATION - A method of obtaining a volumetric image includes obtaining a plurality of volumetric images, the volumetric images generated using respective sets of projection images, wherein the volumetric images and the respective sets of projection images correspond with different respective bins for a physiological cycle, and determining an additional volumetric image using one or more of the projection images from each of the sets that correspond with the different respective bins for the physiological cycle, wherein the act of determining the additional volumetric image is performed using a processor. | 10-03-2013 |
