The Precise Answer to Stereotactic Radiation Therapy

Continued technical evolution has expanded stereotactic treatment to both intracranial and extra-cranial sites. It is developing rapidly, particularly in developed radiation therapy markets such as North America and Europe. Stereotactic Radiation Therapy (SRT) has the potential to reduce fractions and improve survivorship. Stereotactic Body Radiation Therapy (SBRT) for lung cancer is an example of an alternative to surgery.

The capability of linear accelerators to deliver higher doses for SRT is increasing and it is expected that this technique will be applied more widely in clinical settings. To deliver even higher doses, new technology must be provided that is compatible with stereotactic delivery, namely high-precision patient positioning and intra-fraction motion management.

Catalyst HD offers a complete Surface Image Guided Radiation Therapy (SIGRT) solution on SRT for online patient tracking before and during treatment delivery, thus ensuring the best possible treatment outcome without non-prescribed doses. The Catalyst HD can also be used for VMAT, IMRT and 3D CRT delivery.
