A scanning board for automatic registration and fusion of two body positions

Abstract

The invention discloses a double-position automatic registration and fusion scanning board and belongs to the technical field of medical instruments. The double-position automatic registration and fusion scanning board comprises a four-quadrant scanning board (1), a connecting board (2), oblique rods (3) and cavities (4). The four-quadrant scanning board (1) is a square thin board, and the two oblique rods (3) perpendicularly intersecting with each other are embedded in the middle of the four-quadrant scanning board. The point of intersection of the two oblique rods (3) is the center of the four-quadrant scanning board. The cavities (4) are formed inside the oblique rods (3) with the diameter of 3-5mm and are communicated with each other. The cavities are filled with fillers. Both ends of each oblique rod are sealed. The four-quadrant scanning board (1) is fastened with one side of a machine frame through the connecting board (2). According to the double-position automatic registration and fusion scanning board, position consistency in registration and fusion of scanned images of the two positions of MRI (magnatic resonance imaging) transverse position and sagittal position is achieved, fineness of MRI images is improved, and richer images are provided for information giving of clinical diagnosis.

Description

technical field [0001] The invention relates to a scanning board for automatic registration and fusion of double body positions, which belongs to the technical field of medical appliances. Background technique [0002] Image fusion technology can significantly improve the display information of a single image, which is of great value in clinical medicine. MRI transverse and sagittal scans can provide different image information respectively. If the information of the two body scans can be fused together, the Obtaining richer image information, thereby providing more detailed image information for clinical use, can effectively reduce the error rate of clinical diagnosis, but because the scanning parameters of MRI transverse and sagittal scan images are inconsistent, it is difficult to grasp the coincidence of the patient's body position. It is often difficult to find a consistent body position in the scanned images, which brings great difficulties and uncertainties to the sub...

[0002] Image fusion technology can significantly improve the display information of a single image, which is of great value in clinical medicine. MRI transverse and sagittal scans can provide different image information respectively. If the information of the two body scans can be fused together, the Obtaining richer image information, thereby providing more detailed image information for clinical use, can effectively reduce the error rate of clinical diagnosis, but because the scanning parameters of MRI transverse and sagittal scan images are inconsistent, it is difficult to grasp the coincidence of the patient's body position. It is often difficult to find a consistent body position in the images obtained by scanning, which brings great difficulties and uncertainties to the subsequent image registration and fusion

At present, most registration studies based on feature points use approximate body feature points for registration, and the approximate registered images are used for fusion, and the clinical application value of the results will be greatly reduced; It is not very convenient to determine the point, and the fusion of the two positions is still difficult to achieve
