Problems solved by technology

[0003] The analysis of this clinical phenomenon shows that after the addition of iodine contrast agent to the human tissue, the equivalent thickness changes, and the automatic mA inspection technology is used, the inspection conditions have changed unexpectedly, and then the CT value of the reconstructed image is shifted and distorted , cysts will shift in CT value; in addition, other lesions, such as tumor nodules, may also experience CT value distortion in enhanced scan reconstruction images

Abstract

The invention relates to the technical field of medical equipment, and particularly relates to an image quality control device and examination bed integrated technical method. The device comprises anexamination bed, wherein a fixed soft cushion, a replaceable human body liner or a replaceable covering object are arranged on the examination bed, calibration objects are arranged in the fixed soft cushion, the replaceable human body liner and the replaceable covering object, the spatial distribution of the calibration objects in the fixed soft cushion is that the longitudinal axis directions ofthe examination bed, the fixed soft cushion and the calibration objects are all consistent, and the spatial distribution of the calibration objects in the replaceable human body liner and the replaceable covering object is that when the replaceable human body liner or the replaceable covering object is located on the examination bed and in a working state, the longitudinal axis direction of the calibration objects is consistent with the longitudinal axis direction of the examination bed. The image quality control device and examination bed integrated technical method can correct data offset during in-vivo focus examination.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an integrated technical method of an image quality control device and an examination table. Background technique [0002] Current multi-slice spiral CT machines generally use automatic milliampere technology to reduce radiation dose. If enhanced examination is performed, cysts with no blood supply in the human body that should not be enhanced before and after injection of contrast medium often appear from several to dozens of Hu. The CT value changes. [0003] The analysis of this clinical phenomenon shows that after the addition of iodine contrast agent to the human tissue, the equivalent thickness changes, and the automatic mA inspection technology is used, the inspection conditions have changed unexpectedly, and then the CT value of the reconstructed image is shifted and distorted , cysts will shift in CT value; in addition, other lesions, such as tumor nodules, may...
