Embodiment Construction

[0046] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0047] The DICOM image and the vector diagram in DXF format are two independent and intersecting images based on the current window as the reference coordinate system. DXF images are displayed on top of DICOM images.

[0048] In order to measure the size of the bone, we load the vector map and move and rotate the loaded vector map to match the bone to be operated on. In order to make the matching results easier to observe and more accurate, we have added the function of synchronous movement and synchronous scaling of DICOM images and vector graphics.

[0049] We assume that the DICOM image pixel f(x i ,y i )(0≤ii ,y i ), where N is the number of medical image pixels. Assuming that the loaded DXF vector image is displayed in the image pixel f of the client area 1 (x1 i ,y1 i )(0≤ii ,y1 i ), where N1 is the number of image pixels of the vector graph...

Abstract

The invention provides a method for displaying a vector graph on a medicinal image. According to the relative change of boundary rectangles of the medicinal image and the vector graph, the method enables the vector graph to change together with the medicinal image. After the method is used, a medicinal digital imaging and communications in medicine (DICOM) image and an artificial joint industrialtemplate file of a graphics interchange format (DXF) in accordance with industrial standards can be displayed on the same coordinate system through a doctor, and accurate matching of type and size isperformed by the operations such as movement and rotation of an artificial joint graph and the like. Therefore, the method is convenient and quick, is greatly convenient for the doctor to select the type of the artificial joint, and plays a role in assisting and planning the operation of the doctor.

Description

technical field [0001] The invention provides a method for displaying vector graphics on medical images, in particular to a method for displaying vector graphics on medical images that can be moved and scaled together. Background technique [0002] Definition of vector graphics: A vector image, also known as an object-oriented image or a drawing image, is defined mathematically as a series of points connected by lines. Graphical elements in vector files are called objects. Each object is a self-contained entity with attributes such as color, shape, outline, size, and screen position. Since each object is a self-contained entity, it can be moved and changed multiple times while maintaining its original clarity and curvature without affecting other objects in the legend. These characteristics make vector-based programs particularly suitable for illustration and 3D modeling, since they often require the ability to create and manipulate individual objects. Vector-based drawin...
