What is conventional simulator in radiotherapy?

Conventional 2-D simulators consist of a diagnostic x-ray tube that is able to image in both static and fluoroscopic modes, while reproducing the radiation properties and geometric movements of the radiotherapy treatment unit.

What is conventional simulation?

Conventional simulation implies the use of a machine capable of the same mechanical movements as treatment units. Images obtained from these machines are essentially two dimensional with the facility to acquire a limited number of axial slices to provide patient contours and tissue density information.

What is CT simulation in radiotherapy?

A CT simulator (CT-S) is a real-time, CT-linked, 3-D treatment planning system, which consists of a CT scanner, a multi-image display, a treatment planning device with real-time visual optimization, and a laser beam projector.

What is the purpose of CT simulation?

CT simulation combines some of the functions of an image-based, 3D treatment planning system and conventional simulator. A CT simulator software system re-creates the treatment machine and allows import, manipulation, display, and storage of images from CT.

How are CT simulators used in radiation therapy?

Commercial CT simulators are available and provide three-dimensional (3D) volumetric radiation therapy techniques to be used on a routine basis in clinical departments.24–31 CT simulation combines some of the functions of an image-based, 3D treatment planning system and conventional simulator.

What is the difference between conventional and CT simulation?

Conventional simulation implies the use of a machine capable of the same mechanical movements as treatment units. Images obtained from these machines are essentially two dimensional with the facility to acquire a limited number of axial slices to provide patient contours and tissue density information.

Can a CT scanner be combined with a physical simulator?

A CT scanner can be combined with a conventional simulator (physical simulation) or used alone for so called virtual simulation (VS), a term coined by Sherouse et al. about 20 years ago [6]. CT simulation and the development of the concept of VS have rendered faster and more precise this procedure than physical simulation [7, 8].

How is a radiation therapy preclinical core simulation done?

Radiation Therapy Preclinical Core Simulation is a critical preparation step before radiation treatment. It is performed at the simulation room equipped with a dedicated big-bore CT scanner. During the simulation, the treatment setup will be simulated by positioning the patient on the flat couch immobilized by specially designed devices.
