Truebeam Stx Technology

Truebeam Stx Technology

TrueBeam STx is a radiotherapy system developed by Varian Medical Systems. It is a versatile platform designed for advanced image-guided radiotherapy and radiosurgery treatments. TrueBeam STx integrates imaging, beam delivery, and motion management technologies to provide precise and accurate radiation therapy. This system is capable of delivering a wide range of treatment techniques, including intensity-modulated radiation therapy (IMRT), stereotactic body radiotherapy (SBRT), and stereotactic radiosurgery (SRS). TrueBeam STx is used in the treatment of various cancers, offering clinicians the tools to deliver tailored radiation therapy with enhanced precision and efficiency.

What are the features of Truebeam Stx?

TrueBeam STx features advanced imaging capabilities such as cone-beam CT for on-board imaging, high-resolution kV imaging, and respiratory gating to ensure accurate patient positioning and tumor targeting. It incorporates dynamic multileaf collimator (MLC) technology for precise beam shaping and intensity modulation, enabling highly conformal dose delivery. The system also includes real-time tumor tracking and motion management tools to account for tumor motion during treatment. TrueBeam STx offers a high dose rate and fast treatment delivery times, enhancing patient comfort and treatment efficiency. Additionally, it provides a wide range of treatment techniques, including IMRT, SBRT, and SRS, making it a versatile platform for delivering personalized and effective radiation therapy.

In which diseases can it be used?

TrueBeam STx can be used in the treatment of various cancers, including but not limited to:

  1. Brain tumors (e.g., gliomas, meningiomas)
  2. Head and neck cancers
  3. Lung cancer
  4. Breast cancer
  5. Prostate cancer
  6. Liver cancer
  7. Pancreatic cancer
  8. Spinal tumors
  9. Bone metastases
  10. Pelvic tumors

These are just a few examples of the diseases for which TrueBeam STx can be utilized to deliver precise and effective radiation therapy.

How is it applied?

TrueBeam STx is applied through a series of steps in the radiation therapy process. Initially, the patient undergoes a simulation session where imaging scans are obtained to define the treatment area. During treatment planning, radiation oncologists delineate the target volume and organs at risk. The treatment plan is optimized using specialized software to determine the appropriate beam angles and dose distribution.

When the patient is positioned on the treatment couch, the system utilizes onboard imaging to verify the target location. The treatment beam is then delivered with high precision and accuracy, utilizing advanced features such as dynamic MLC for beam shaping and respiratory gating for motion management. Throughout the treatment session, real-time monitoring ensures that the radiation is delivered to the intended target while minimizing exposure to surrounding healthy tissues.

By following this comprehensive process, TrueBeam STx enables clinicians to apply tailored radiation therapy with enhanced precision and efficiency, ultimately improving treatment outcomes for patients with various types of cancer.
