Embodiment Construction

[0027] The following describes the data in accordance with a method for utilizing the 3D acquisition and pre-scan method to generate a 2D image pre-scan the region of interest for scanning protocol / tissue based on a scan protocol being utilized for pre-scan image planning 2D the volume of interest scan region / tissue. In one example, this allows the display of different draw 2D 2D pre-scanned image to enhance pre-scanned image of the region of interest / tissue visually.

[0028] image 3 It illustrates such a computer tomography (CT) scanner imaging system 302. The illustrated imaging system 302 includes a stationary gantry 304 and a rotating gantry 306, the rotating gantry 306 is rotatably supported by the stationary gantry 304. Rotation of gantry 306 about the longitudinal axis ( "Z") 308 rotating about the examination region. Subject support member 310 (such as a couch) supporting the examination region of an object or target 308, and the guide or target or target for loadi...

Abstract

An imaging system (302) includes an X-ray radiation source (312) configured to emit radiation that traverses an examination region, a detector array (314) configured to detect radiation that traverses an examination region and generate a signal indicative thereof, wherein the detected radiation is for a 3-D pre-scan, and a reconstructor (316) configured to reconstruct the signal to generate a 2-D pre-scan projection image. The imaging system further includes a console (318) wherein a processor thereof is configured to execute 3-D volume planning instructions (328) in memory to display the 2-D pre-scan projection image (402, 602, 802, 1002) and a scan plan or bounding box (404, 604, 804, 1004) for planning a 3-D volume scan of a region / tissue of interest based on a selected protocol for a 3-D volume scan of a region / tissue of interest being planned and receive an input confirming or adjusting the scan plan box to create a 3-D volume scan plan for the 3-D volume scan of the region / tissue of interest.

Description

Technical field [0001] The following generally relates to imaging, and more particularly relates to a protocol based on a three-dimensional (3D) volume of pre-scanned image data relating to a two-dimensional (2D) projection image pre-scan and using a computer tomography (CT) in the particular application described. Background technique [0002] Computed tomography (CT) scanner includes an X-ray tube, the X-ray tube is rotated around the examination region and emits X-ray radiation passing through the examination region. A detector array detects through the examination region, and wherein a target or object (which attenuate X-ray radiation) and X-ray radiation incident thereon. The detector array generates projection data indicative of the incident X-ray radiation. A reconstructor reconstructs the projection data to generate a three-dimensional examination region, and wherein an indication of a target or object (3D) volumetric image data. [0003] Before performing volume scanning...
