Strictly speaking, any imaging equipment that can perform simulated positioning work can be called a simulation positioning machine, including but not limited to: X-ray simulation positioning machine (X-sim), CT simulation positioning machine (CT-sim), MR simulation positioning machine (MR-sim), and even PET-CT/PET-MR simulation positioning (PET-CT/MR-sim).
As a radiotherapy technician, physicist or doctor understands, simulation scan mainly means simulation localization scan, the first point is that it is used to obtain images before treatment, simulation localization and verification of positional information; the second point is because the simulation scan is a scan that has not been implemented during treatment as opposed to in the treatment state.
Extended information:
For this reason, X-ray simulation positioning machine frame, diagnostic bed and other mechanical components in the physical geometry parameters and precision requirements and treatment equipment is consistent. Here especially the precision is the main concern of the radiotherapy department, which can be said to be the key?point core point.
Particularly diagnostic beds, and radiology X-ray equipment is different, X-ray analog positioning machine for diagnostic beds, the range of motion, precision requirements are very high.
