Radiation therapy is one of the established modes of cancer treatment. Radiotherapy Simulator helps to diagnose the physical extent of the tumor and its relation to the surrounding tissues for proper selection of the size and orientation of the radiotherapy beams. It is also useful to verify a treatment plan. Radiotherapy simulator is an essential tool for improving the quality of radiotherapy for the treatment of cancer patients.
Major sub-systems in the radiotherapy simulator are gantry, collimator, x-ray tube, imaging unit, patient support/positioning system (couch), and remote control console. It is similar to a external beam radiotherapy machine except that diagnostic x-ray is used as source of radiation. The variable focus to axis distance makes it suitable for therapy simulation for a number of teletherapy machines. The collimated x-ray beam passes through the patient (lying on the couch) from one side and the attenuated beam is converted to digital image by an image intensifier coupled with CCD camera system located on the other side. The image intensifier support arm has motorized motions for remote and interactive positioning of the image intensifier at the region of interest. All the motions of the gantry, collimator, and the image intensifier support arm can be controlled through these keypads (on the couch) as well as from the remote control console.
The captured image can be processed / analyzed almost instantly to extract detail information about the tumor location, its volume, and closeness to critical structures. These images will be transferred into the treatment planning computer system for formulating actual radiation dose delivery plan. Immobilization device may be fabricated during this procedure.
- In the conventional form, a radiotherapy simulator is geometrically similar to isocentric external beam therapy machines to reproduce field arrangements for different teletherapy machines.
- All the motions in the main unit and the treatment table are motorized. This ensures faster patient positioning, and no unnecessary burden on the operator.
- It is a computer-controlled system. All motions of the main unit and the patient couch are monitored continuously. A database for the patient and simulation is maintained.
- Digital technology for fast and filmless operation. DICOM compatibility facilitates transfer of simulation plans to other equipments in the network.
- Advanced tools for image processing, annotations, contouring, displaying etc. to assist accurate planning.
- Dedicated collision avoidance system to reduce the risk of patient injury.
- User-friendly user-interface and operations- The operator interacts with the system using the mouse and keyboard located at the control console.
- Enhanced Security: In addition to physical key, selective access to operation, machine parameters, and patient/treatment data through password protection.
