Filed:

Sep 9, 2009

Appl. No.:

12/556270

Inventors:

Di Yan - Auburn Hills MI, US
Jian Liang - Troy MI, US
Alvaro Martinez - Bloomfield Hills MI, US

Assignee:

William Beaumont Hospital - Royal Oak MI

International Classification:

A61N 5/10

US Classification:

378 65

Abstract:

A system for radiotherapy includes a first imaging system and a second imaging system. The first imaging system generates projection images of an area of interest of an object, and the second imaging system generates portal images of the area of interest of the object synchronously with the generation of the projection images. The radiotherapy system further includes a processing system that receives data associated with the projection images and data associated with the portal images and reconstructs 3D and 4D portal images from the projection images and the portal images.

International Classification:

A61B 6/03
A61B 6/00

US Classification:

378014000, 378065000

Abstract:

A method of treating an object with radiation that includes generating volumetric image data of an area of interest of an object and emitting a therapeutic radiation beam towards the area of interest of the object in accordance with a reference plan. The method further includes evaluating the volumetric image data and at least one parameter of the therapeutic radiation beam to provide a real-time, on-line or off-line evaluation and on-line or off-line modification of the reference plan.

International Classification:

A61G 7/065
A61G 7/00

US Classification:

5601

Abstract:

A cradle for supporting an anatomical portion of a patient during radiotherapy includes a plurality of air chambers and at least one pressure regulator that adjusts the pressure in each air chamber. The cradle may be connected to an electronic control unit that sends instructions to the at least one pressure regulator to pressure each air chamber to a desired pressure.

International Classification:

A61B 6/03

US Classification:

378 9

Abstract:

A tetrahedron beam computed tomography system including an x ray source array that sequentially emits a plurality of x ray beams at different positions along a scanning direction and a collimator that intercepts the plurality of x-ray beams so that a plurality of fan-shaped x-ray beams emanate from the collimator towards an object. The system includes a first detector receiving a first set of fan-shaped x ray beams after they pass through the object, the first detector generating a first imaging signal for each of the received first set of fan-shaped x-ray beams and a second detector receiving a second set of fan-shaped x ray beams after they pass through the object, the second detector generating a second imaging signal for each of the received second set of fan-shaped x-ray beams. Each detector and source pair form a tetrahedral volume. In other embodiments, the system may also have more than two detectors arrays and/or more than one source array. Each pair of source array and detector array forms a tetrahedral volume. Using multiple detector arrays and source arrays can increase field of view, reduce the length of detector and source arrays so that the imaging system is more compact and mobile.
