Interactive 2D and 3D medical image registration parameter automatic generation method

Abstract

The invention relates to an interactive 2D and 3D medical image registration parameter automatic generation method. Compared with the prior art, the method solves the defects that initial registration parameters are poor in search precision and low in search efficiency. The method comprises the following steps: loading three-dimensional image data; rendering and reconstruction of a three-dimensional model are realized on the window, two-dimensional mapping is performed on the three-dimensional model, and an image after real-time mapping and an X-ray image to be registered are aligned and displayed; loading a two-dimensional image to be registered and drawing the two-dimensional image on a window in a two-dimensional texture form; and dragging the mouse to align the three-dimensional model and the two-dimensional image so as to obtain proper registration parameters. According to the method, the difference between the quality of the image drawn on the window and the quality of the X-ray image needing to be registered after the three-dimensional body data is subjected to maximum density projection is comprehensively considered, alignment of the two images can be completed with high quality, and a group of proper initial registration parameters can be obtained and printed and output on a console.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to an interactive 2D and 3D medical image registration parameter automatic generation method. Background technique [0002] With the advancement of medical imaging equipment, for the same patient, images containing accurate anatomical information such as CT and MRI can be collected; at the same time, images containing functional information such as SPECT can also be collected. However, making a diagnosis by observing different images requires spatial imagination and the doctor's subjective experience. With the correct image registration method, a variety of information can be accurately fused into the same image, making it easier and more accurate for doctors to observe lesions and structures from various angles. At the same time, through the registration of dynamic images collected at different times, the changes in lesions and organs can be quantitatively analyze...
