Flexible die body suitable for performance evaluation of magnetic resonance and CT imaging equipment

Abstract

The invention discloses a flexible die body suitable for performance evaluation of magnetic resonance and CT imaging equipment. The flexible die body comprises a flexible die body main body, wherein the flexible die body main body comprises a cylindrical cavity layer, the top of the cylindrical cavity layer is provided with an open type wire pair, and the open type wire pair comprises a cavity cylinder array module. According to the invention, the open wire pair and the cylindrical cavity module are arranged; the spatial resolution and the image uniformity of magnetic resonance and CT equipment can be met at the same time; density resolution, low contrast resolution capability, measurement requirements of key performance parameters such as an image signal-to-noise ratio and the like are satisfied; meanwhile, the spontaneous movement condition of human organs can be simulated; and the possible images of the spontaneous motion on the image quality are obtained, so that the stability of the imaging quality in the actual clinical diagnosis application of the magnetic resonance and CT equipment is ensured, and more accurate magnetic resonance and CT images are provided for the clinicaldiagnosis of doctors. The flexible die body has wide popularization value and good social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of medical measurement and detection equipment, and in particular relates to a flexible phantom suitable for performance evaluation of magnetic resonance and CT imaging equipment. Background technique [0002] Medical imaging technology represented by magnetic resonance and CT imaging has become a routine diagnostic technology in hospitals or other medical institutions. Most tertiary hospitals are equipped with magnetic resonance and CT equipment for clinical diagnosis. Both magnetic resonance and CT imaging techniques can provide a three-dimensional computer model of the human body. Among them, the soft tissue resolution of magnetic resonance technology is high, which can realize functional imaging, but its application is limited when there are metal implants; CT technology can be used without geometric distortion. It accurately reflects the three-dimensional structure of the human body, and the scanning is...

Problems solved by technology

[0004] The existing MRI and CT phantoms have two main limitations in application: (1) MRI and CT require phantoms of different materials, and it is impossible to directly compare the performance indicators between MRI and CT equipment, and increase (2) The phantom is generally made of hard material and cannot be deformed, so it cannot simulate the spontaneous movement of the organs in the human body, and it is different from the actual clinical diagnosis, so it cannot truly reflect the actual patient diagnosis.
