Three-dimensional directional frame for abdominopelvic PET (Position-emission Tomography), CT (Computed Tomography) and MR (Magnetic Resonance) images fusion

Abstract

The invention discloses a three-dimensional directional frame for abdominopelvic PET (Position-emission Tomography), CT (Computed Tomography) and MR (Magnetic Resonance) images fusion. The three-dimensional directional frame comprises a first U-shaped bracket, a second U-shaped bracket and a support; the width of openings of the U-shaped frames can be adjusted; the first bracket is parallel to the second bracket; the space between the first bracket and the second bracket can be adjusted; the support is vertically intersected with the two brackets; a pointed jackscrew is arranged on one bracket and jacks toward the inner side from the outer sides of the U-shaped frames; more than three locating bars are connected between the first bracket and the second bracket; at least two locating bars are intersected; the locating bars are detachable, each one comprising three sets of locating bars which are respectively filled with a PET imaging agent, a CT imaging agent and an MR imaging agent; the locating bars are used for respectively adding locating information for PET image data, CT image data or MR image data. The three-dimensional directional frame is simple and convenient to operate, can be applied to PET, CT or MR machines of any brand and mode, plays the main functions of expensive PET / CT or PET / MR machines, and increases the application value of single device.

Description

technical field [0001] The invention relates to an auxiliary device for medical imaging diagnosis and treatment, in particular to a stereotaxic frame for the abdomen and pelvis. Background technique [0002] With the continuous advancement of modern medicine, radiology and computer technology, the development of medical imaging technology is changing with each passing day, and various medical imaging examination methods based on different imaging principles emerge in endlessly. So far, the imaging modes of medical imaging can be divided into two categories: anatomical structure imaging and functional metabolic imaging. Among them, CT (Computed Tomography) and MR (Nuclear Magnetic Resonance) can reflect the anatomical structure information of the human body and can perform three-dimensional imaging. CT has fast scanning speed, high spatial resolution, and clear imaging of rigid body (bone, joint, etc.) lesions, but the imaging of soft tissue (vascular, nerve, prostate, joint...
