Quality-control multi-parameter model for magnetic resonance imaging system and CT equipment

Abstract

The invention provides a quality-control multi-parameter model for a magnetic resonance imaging system and CT equipment. The quality-control multi-parameter model comprises a box body and multiple test blocks; the test blocks comprise test layers and supporting layers for stacking and positioning the test blocks, the multiple supporting layers are sequentially stacked and arranged in the box body,and the test layers are arranged in the supporting layers; the multiple test layers comprise image geometric distortion test layers, low-contrast-resolution test layers and uniformity and signal-to-noise-ratio test layers, or the multiple test layers comprise any two of image geometric distortion test layers, low-contrast-resolution test layers and uniformity and signal-to-noise-ratio test layers. The quality-control requirement of the MRI and the quality-control requirement of the CT equipment can be simultaneously met, the product function is diverse, different test requirements can be met,multiple parameters can be simultaneously measured, the accuracy and modularization are high, and the test layers can be flexibly combined.

Description

technical field [0001] The present invention relates to the neighborhood of magnetic resonance imaging system and CT equipment quality control, in particular to a magnetic resonance imaging system and CT equipment quality control multi-parameter phantom Background technique [0002] With the development of the economy, people pay more and more attention to their own health, and the requirements for the quality of life are also increasing, so the demand for medical imaging equipment continues to grow. Therefore, ensuring the safe operation of medical imaging equipment has become an essential task. [0003] Both magnetic resonance imaging (MRI) systems and CT equipment are large-scale medical imaging equipment, with complex structures, sophisticated devices and no versatility, which increases the difficulty of maintenance work. Once these equipment fails, it may cause harm to medical staff. Personal injury, and equipment downtime for maintenance will cause huge economic losse...
