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.

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.

International Classification:

F02C 7/143
F02C 3/30
F02C 3/04

Abstract:

A combined water-wash and water injection cooling system for a gas turbine engine including a water delivery system, an air delivery system, and a controller configured to couple to the gas turbine engine, the water delivery system, and the air delivery system to access and execute one or more routines. The water delivery system includes one or more spray nozzles to spray water upstream and directly in front of a compressor of the gas turbine engine. The air delivery system is configured to provide air from the compressor to the water delivery system so that the one or more spray nozzles spray atomized water into the compressor of the gas turbine engine during a cooling mode to cool the compressor. During an on-line water wash mode, air from the air delivery system to the water delivery system is turned off to enable the one or more spray nozzles to spray non-atomized water into the compressor of the gas turbine engine to wash the compressor.
