What does im74 mean?

im74 means image in Chinese.

Generally, small nodules with a diameter less than 5mm in the lungs are found to only occupy one level, because some clinicians are not good at reading films, and the images on CT films are small and may not be visible. Therefore, the diagnostic imaging doctor will indicate in the report which layer the lesion is located, usually expressed by im, such as im35, indicating that the small nodule is on the 35th layer.

Image is also called image:

Refers to the imaging method of non-photographic imaging sensors, which is essentially an extension of photographic images. Photos usually refer to optical photography and are recorded on photosensitive film, which is passive remote sensing imaging. Images can receive visible light, infrared, thermal infrared and microwave information from ground objects through optical-mechanical, optical-electronic or antenna scanning.

Recorded on magnetic tape or recorded on photosensitive film through electro-optical conversion. Compared with photographs, it has a wider range in content and form. Using "image" to include (rather than replace) "photograph" is the result of aerial photography and reconnaissance developing into remote sensing, and photography developing into imaging.
