Embodiment Construction

[0021] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 and figure 2 As shown, the present invention is a stereotaxic frame for fusion of PET, CT and MR images in the abdomen and pelvis, including a first bracket, a second bracket and a bracket.

[0023] The first bracket and the second bracket are U-shaped frames respectively, and the basic structure of the first bracket and the second bracket is the same, as figure 2 As shown, the first bracket consists of a sleeve 1 and right-angled plates 6, 7 inserted on both sides of the sleeve 1, and the second bracket consists of a sleeve 3 and right-angled plates 8, 9 inserted on both sides of the sleeve. constitute. In the first support and the second support, the opening width of the U-shaped frame is determined by adjusting the relative positions of the right-angle plates on both sides and...

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...
