What does the direction of coronal photography mean?

Refers to the shooting direction in X-rays, that is, the left and right directions.

According to the location where we usually shoot, I roughly sum up the shooting directions of X-rays into sagittal direction (front-back/front-back direction, also called ventral/abdominal direction), coronal direction (left/right/left direction), oblique direction (left front/right front direction, left back/right back direction, head side/foot side oblique direction) and up-and-down direction (jaw/collar direction).

Digital radiography (DR) is also a newly developed digital imaging technology, which is similar to computerized radiography (CR), but its basic principle and structure are different. DR is developed on the basis of digital fluorescence photography (DF). It takes the image intensifier tube as the information carrier, receives the X-ray information transmitted through the human body, converts it into digital signals after being collected by the camera, and then carries out digital processing.
