Problems solved by technology

At the same time, for the geometrically calibrated tube-beamer-detector combination, under different tube heat capacity conditions, due to the heel effect caused by the thermal expansion and contraction of the anode target surface, the focus drift will also bring the radiation area changes, so that the umbra area cannot completely cover the sensing area of ​​the detector, resulting in the occurrence of occlusion

Embodiment 1

[0087] Please refer to Figure 1 to Figure 3 , Embodiment 1 of the present invention is:

[0088] An imaging method for medical imaging, such as figure 1 shown, including the following steps:

[0089] S1. Obtain the basic information of the patient. The basic information of the patient includes height, weight and age, etc.

[0090] S2. Acquire initial exposure parameters and select a beamer according to the basic information. Exposure parameters include selectable tube current, voltage, filter material and thickness, etc. The current and voltage in the initial exposure parameters can be set smaller. In this embodiment, in principle, the light beam device can be in any shape, such as a one-dimensional narrow slit, a two-dimensional rectangle or square, circular hole or polygon. For a one-dimensional narrow slit, the beamer consists of two long metal baffles that can move in opposite or opposite directions. For two-dimensional rectangular or square openings, the beamer con...

Embodiment 2

[0108] Please refer to Figure 5 , the second embodiment of the present invention is:

[0109] An imaging terminal 100 for medical imaging, corresponding to the method in Embodiment 1, includes a memory 1, a processor 2, and a computer program stored in the memory 1 and operable on the processor 2, the processing Implement the following steps when the device 2 executes the computer program:

[0110] Obtain basic information of patients;

[0111] Acquiring initial exposure parameters and selecting a beamer according to the basic information;

[0112] Perform initial exposure to the patient's part to be diagnosed according to the initial exposure parameters and the selected beam device to obtain an initial image;

[0113] acquiring a region of interest on the initial image;

[0114] adjusting the initial exposure parameters according to the image quality of the region of interest to obtain secondary exposure parameters;

[0115] adjusting the shape and size of the beamer ac...

Abstract

The invention discloses an imaging method of a medical image and a terminal. The imaging method comprises the steps of acquiring basic information of a patient; according to the basic information, acquiring initial exposure parameters and selecting a light bundle device; according to the initial exposure parameters and the selected light bundle device, exposing a to-be-diagnosed part of the patient for the first time, and obtaining an initial image; acquiring an interested region on the initial image; according to the image quality of the interested region, adjusting the initial exposure parameters, and obtaining secondary exposure parameters; according to the shape and size of the interested region, adjusting the shape and size of the light bundle device; according to the secondary exposure parameters and the adjusted light bundle device, exposing the to-be-diagnosed part of the patient for the second time, and obtaining the medical image. The imaging method has the advantages of being simple in operation and high in flexibility and effectively lowering the radiation dose.

Description

technical field [0001] The present invention relates to the field of imaging technology, in particular to a medical imaging imaging method and terminal. Background technique [0002] X-rays have been widely used in medical diagnosis, which is mainly based on the penetration, differential absorption, photosensitivity and fluorescence of X-rays. When X-rays pass through the human body, they are absorbed in different degrees. For example, the amount of X-rays absorbed by bones is more than that absorbed by muscles. Then, through the information of the density distribution of various parts of the human body, the fluorescence effect or There is a big difference in the strength of the photosensitive effect, so shadows of different densities will be displayed on the fluorescent screen or on the photographic film. According to the comparison of shadow shades, combined with clinical manifestations, laboratory results and pathological diagnosis, it can be judged whether a certain par...
