Noun interpretation:
1. Radiation field: X-ray incident in the exposed area of the limb
Listen to the canthus: external ear canal and lateral canthus
Sagittal plane: two parts of the human body are broken and left in front and back, and the cross section is sagittal plane
Direct introduction method: the contrast agent is introduced into the an through the natural channel mouth, or through the skin puncture, from the needle tube or the connective guide
The injection contrast agent, which is introduced into the lumen an of the external isolation, is called direct introduction
5 pixels: the smallest unit that forms a digital image
1 window width: the scope of CT values represented by the 16th grade on CT image:
2 grid ratio: the ratio between the height of the filter grid lead bar and the width of the lead bar
3 right anterior oblique position: the right front of the body is close to the dark box, the X ray ing from the left behind the body, and the right front is ejected
Effective focus: the actual focus is projected in different directions
The digital matrix digital image all pixel arrays are called digital image matrix
1 photo contrast: the optical density of the tissue image in the image
Image: fluorescence in the fluorescence image indicates that the amount of x rays that are absorbed by the body of the body that is being detected by the body of the body is more than that
The dark parts indicate that the amount of x rays being absorbed by the limb is less than that of the x rays. The image of the fluorescence image is described
For just as the
Practical focus: the impact area on the X-ray tube anode is called the actual focal point when the electron from the filament is focused.
Center line: the X line at the center of the X ray is called the center line
5DSA: digital subtraction angiography
1 negative as: use of light to observe X-ray image, through strong visible part of the said inspection b
