International Classification:

G01N 23/04

US Classification:

378 62, 378 968

Abstract:

A method for imaging an object includes radiating the object of interest and sensing the radiation that penetrates through the object using a detector having at least one active area and at least one inactive area, determining when the radiation is completed using information received from the inactive area of the imaging detector, and reconstructing an image of the object using information received from the active area of the imaging detector. A medical imaging system and a computer-readable medium are also provided.

Appl. No.:

12/637069

Inventors:

James Zhengshe Liu - Glenview IL, US
Feng Gao - Naperville IL, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

G01T 1/20

US Classification:

25037009

Abstract:

A system and method for eliminating image artifacts caused by electromagnetic interference (EMI) on a digital x-ray detector. The system and method includes a digital x-ray detector panel having an array of pixels in rows and columns, with a plurality of data lines coupled to the columns of pixels and a plurality of scan lines coupled to the rows of pixels. The system and method uses certain photodiodes in a row of the pixel array for measuring EMI with corresponding scan line and FETs deactivated and eliminating the EMI and image artifacts with the remaining photodiodes in the row with corresponding scan line and FETs activated.
