Abstract:

In some embodiments, a method includes receiving, in a processor, information indicative of (i) a treatment plan defining planned treatment beams, (ii) a patient volume relative to a reference, (iii) ideal intersections of the planned treatment beams with the patient volume at the time the patient is to be treated, (iv) any constraints that prevent achievement of the recommended repositioning using only the patient support, (v) an allowable change to a gantry position from a planned value and an allowable change to a collimator position from a planned value; defining, in the processor, a plurality of alternatives based at least in part on the information indicative of any constraints of the patient support and the information indicative of allowable movement of the gantry and collimator, each alternative defining a modified patient support position and modified beams, each modified beam being based at least in part on a respective one of the planned treatment beams, the change to the position of the gantry for the respective planned treatment beam and the change to the position of the collimator for the respective planned treatment beam; determining, in the processor, for each modified beam of each alternative, an intersection of the patient volume and the modified beam, with the patient volume positioned on the patient support and the patient support having the modified patient support position defined by the alternative; and defining, in the processor, for each alternative, a measure of difference between the ideal intersections and the intersections for the modified beams of the alternative.

378207
Abstract:

Some embodiments include determination of a first projection image of a phantom based on first imaging geometry parameters associated with a first radiation-based imaging system and on a virtual model of the phantom, acquisition of a second projection image of the phantom based on radiation emitted from the first radiation-based imaging system, the phantom located at a first position and determination of a difference between the first projection image and the second projection image. Second imaging geometry parameters are determined based on the first imaging geometry parameters and the difference between the first projection image and the second projection image, a third projection image of the phantom is determined based on the second imaging geometry parameters and on the virtual model of the phantom, and a fourth projection image of the phantom located at the first position is acquired based on radiation emitted from the first radiation-based imaging system. A difference between the third projection image and the fourth projection image is determined and it is determined that the difference between the third projection image and the fourth projection image is less than a threshold.

Method For Reconstructing An Object Subject To A Cone Beam Using A Graphic Processor Unit (Gpu)
view source
US Patent:

20080043024, Feb 21, 2008
Filed:

May 8, 2007
Appl. No.:

11/745535
Inventors:

Thomas Schiwietz - Munchen, DE
Supratik Bose - Concord CA, US
Assignee:

SIEMENS CORPORATE RESEARCH, INC. - Princeton NJ
International Classification:

G06T 11/20
US Classification:

345442000
Abstract:

A method for reconstructing an object subject to cone beam passing through the object and generating projection images of the object using a graphic processing unit (GPU). The method applies a non-linear curvature-based smoothing filter to the projection images. The method applies a high-pass filter to the curvature-smoothed images. The method backprojects the projection images into an output volume using voxel driven backprojection. The method removes cupping artifacts from the output volume convolving every slice with a Butterworth kernel and adding the result to the slice weighted by a scaling factor.
