The invention discloses a method and apparatus for acquiring a medical two-dimensional image and belongs to the image processing field. The method includes the following steps that: the rectangular coordinate system of a three-dimensional model is determined, wherein the three-dimensional model is a model generated by a plurality of computer tomographic (CT) images along a target direction, and the direction of one coordinate axis of the three-dimensional rectangular coordinate system is the same with the target direction; the cross section of the three-dimensional model, which is corresponding to the medical two-dimensional image, is determined according to user operation, wherein the cross section satisfies a three-variable linear equation that Ax+By+Cz+D=0; the intersection line of the cross section and the plurality of CT images is determined; corresponding CT image data of the intersection line on the CT images are obtained; and the medical two-dimensional image corresponding to the cross section is generated according to the corresponding CT image data of the intersection line on the CT images. With the method and apparatus of the present invention adopted, the flexibility of image dimensionality reduction is effectively improved. The method and apparatus are used for image dimensionality reduction.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a method and device for acquiring medical two-dimensional images. Background technique [0002] In the medical scene, multiple X-ray computed tomography (English: Computed Tomography; CT for short) images can be used to generate a three-dimensional model along the target direction (the target direction is usually the direction perpendicular to the plane where the CT image is located) through the medical device. Observe the lesion and plan the operation plan through the three-dimensional model. In the three-dimensional model, the distance between every two adjacent CT images (that is, the layer spacing) is equal, and each CT image can be regarded as a medical two-dimensional image. The 3D model is displayed in the form of a 3D image. When planning a surgical plan, medical personnel need to check the 3D model of the key surgical node (such as the position of the lesion approaching...
