International Classification:

G01D018/00
A61B006/04
US Classification:

378/207000, 378/037000
Abstract:

A method for calibration of an imaging system, the imaging system including a radiation source and a digital detector. The method includes providing a calibration phantom system including a first phantom element material block having a first surface at a first height, wherein the first phantom element material block at least partially includes a first material having a first attenuation coefficient. Providing a calibration phantom system also includes providing a second phantom element material block having a second surface at a second height different than the first height, the second phantom element material block at least partially including a second material having a second attenuation coefficient different than the first attenuation coefficient, wherein the first phantom element material block and said second phantom element material block are co-positioned on a detector. The method also includes imaging the calibration phantom system to obtain phantom images, processing the phantom images, and extracting a plurality of calibration values from the processed phantom images.

US Patent:

20030215057, Nov 20, 2003
Filed:

May 15, 2002
Appl. No.:

10/063806
Inventors:

Dinko Eduardo Trotter - Clifton Park NY, US
Serge Muller - Guyancourt, FR
Assignee:

GENERAL ELECTRIC COMPANY - Schenectady NY
International Classification:

G01B015/02
US Classification:

378/089000
Abstract:

A method of estimating an asymmetrical scatter signal distribution wherein asymmetry is introduced by angular incidence of radiation, which has been emitted from a source and transmitted through an object to be imaged, on a detector, is disclosed. This method includes, in an embodiment, modifying scatter that would be derived wherein the radiation is directly incident on the detector with zero degrees of inclination, using an asymmetry factor which indicates the shape and magnitude of the scatter signal distribution and which varies with an angle at which the radiation is incident on the detector, a mean attenuation coefficient of the object, and a distance the radiation has traveled through the object. The estimated scatter provides for correction of scatter in a image.

Sep 10, 2004
Appl. No.:

10/937433
Inventors:

Dinko Trotter - Clifton Park NY, US
International Classification:

A61K 51/00
C07K 16/46
US Classification:

424001490, 530391100
Abstract:

Disclosed are multispecific macromolecular constructs, blocking agents and radiolabeled effector molecules, as well as kits and methods for imaging tissue of interest in a mammalian subject. The multispecific macromolecular construct is capable of binding a radiolabeled effector molecule that can be imaged, as well as a disease marker such as for example a tumor specific antigen expressed on the surface of tumor tissue. The blocking agent comprises, or alternatively consists of, an unlabeled form of the radiolabeled effector conjugated to a carrier protein or polypeptide, said carrier protein or polypeptide preferably being non-immunogenic or having low immunogenicity. The invention further contemplates methods of imaging diseases or disorders in a mammalian subject using said compositions
