New & Used Radiotherapy Simulator

Tips for buying Radiotherapy Simulator

1. Radiotherapy simulator buyers must make sure that the patient can be positioned with respect to the beam in such a way that radiotherapy is simulated as close as possible to the patient.
2. The radiation treatment simulation system should, therefore, have a SAD ranging from 80 to 150 cm and a source-to-image distance (SID) ranging from 80 to 200 cm.
3. The gantry should be able to rotate ±150° above and ±180° below 100 cm SAD.
4. To allow for proper patient positioning, the patient table should be capable of a wide range of translations and rotations.
5. The radiotherapy simulator should be capable of ±90° collimator rotations and image intensifier translations of ±20 cm laterally, ±20 cm longitudinally, and 60 cm radially.
6. To enhance details and minimize the image width of the treatment area, smaller focal spot sizes of 0.6 mm or 1 mm are preferred.
7. To meet minimum recommendations, the radiotherapy simulator should have an image x-ray field of 45 cm² at 100 cm SAD, a 12° anode angle, a 23 cm image intensifier with a coverage area of 70 cm².
8. CT-based RF radiotherapy simulation systems should include the following standard system components: CT gantry, laser alignment, control console, and workstation. If the CT scanner is not included, the radiotherapy simulator system should be able to interface with any DICOM-compatible CT scanner.
9. The scanner should have a large bore diameter of 70-80 cm, a 60 cm maximum field of view, and multislice capability with 0.5, 1, 2, 4, 5, and 10 mm slice widths.
10. The radiation treatment simulation system should be able to reconstruct 20 images per second, digitally reconstruct radiographs in less than 1 second, and instantaneously reconstruct with beam's-eye-view.
11. Networking and system interfacing are important considerations.
12. The radiotherapy simulator suite should include a shielded room for the simulator and x-ray generator, as well as separate control and treatment planning rooms. The control room should be separated from the simulator room by a large lead glass or plate-glass window.
13. Some radiotherapy simulator systems may require the use of a pit for installation. This provides both an anchor for the base of the simulator and a conduit for cables and wiring.
