Planning System For Convergent Radiation Treatment
US Patent:
6782073, Aug 24, 2004
Filed:
Sep 23, 2002
Appl. No.:
10/252980
Inventors:
William F. Collins - Clayton CA
Assignee:
Siemens Medical Solutions USA, Inc. - Malvern PA
International Classification:
A61N 510
US Classification:
378 65, 378 84, 600431
Abstract:
A system includes determination of a treatment plan for delivering convergent radiation to a target based at least on a decrease in intensity of the convergent radiation due to material intercepted by the convergent radiation prior to reaching the target and on an increase in intensity of the convergent radiation due to a geometry of the convergent radiation. Some aspects include determination of a dose enhancement at the target over time due to contrast agent located at the target, wherein the determination of the treatment plan is based at least on the dose enhancement over time.

Integrated Automatic Exposure Control For Portal Imaging In Radiotherapy
US Patent:
6148060, Nov 14, 2000
Filed:
Oct 13, 1998
Appl. No.:
9/172709
Inventors:
William F. Collins - Clayton CA
Francis Cheng - Palo Alto CA
Francis Cheng - Palo Alto CA
Assignee:
Siemens Medical Systems, Inc. - Iselin NJ
International Classification:
A61N 510
US Classification:
378 65
Abstract:
Method and system aspects for integrated automatic exposure control for portal imaging in radiotherapy are described. In an exemplary method aspect, the method includes controlling scanning and blanking of a target of a camera pick-up tube to capture an initial image, and analyzing the initial image to establish an initial image intensity. The method further includes utilizing the initial image intensity to determine a time for scanning a next image, and combining a scan of the next image with the initial image to produce a portal image with a maximized signal to noise ratio.
X-Ray Therapy Electronic Portal Imaging System And Method For Artifact Reduction
US Patent:
7027558, Apr 11, 2006
Filed:
Nov 3, 2004
Appl. No.:
10/981223
Inventors:
Farhad Abbasi Ghelmansarai - Danville CA, US
William F. Collins - Clayton CA, US
William F. Collins - Clayton CA, US
Assignee:
Siemens Medical Solutions USA, Inc. - Malvern PA
International Classification:
G01N 23/00
US Classification:
378 65, 378 19, 25037011, 25037009
Abstract:
X-ray therapy EPI artifact reduction and control of imaging is provided. Scanning of images is synchronized with the pulse rate of the x-rays. The scanning period is longer than the pulse rate period, so artifacts are generated within the resulting images. Due to the synchronization, the pulse variation artifacts are aligned across multiple images. The synchronization and resulting alignment of linear artifacts allows for gain correction as a function of lines within the image. Such gain correction reduces or removes non-linearities associated with pulse rate variation.
Focused Radiation Visualization
US Patent:

Assignee:
Siemens Medical Solutions USA, Inc. - Iselin NJ
International Classification:
A61B 6/08
US Classification:
378206, 378 84
Abstract:
A system includes substantial focus of radiation on a focal area, the focused radiation following a radiation path from a lens to the focal area, and projection of light on a surface so as to substantially indicate an intersection of the radiation path with the surface. In some aspects, the light projected on the surface substantially indicates a distance between the surface and the focal area.
