Versa HD Linear Accelerator: Targeting Tumors with Sub-Millimeter Accuracy Technology and Treatment Center


Versa HD is a unique and advanced radiotherapy platform that is designed to facilitate advanced radiation therapy procedures, such as intensity-modulated radiation therapy (IMRT), image-guided radiation therapy (IGRT), stereotactic radiotherapy (SRT), and stereotactic radiosurgery (SRS). These radiotherapy modalities demand superior precision in terms of tumor targeting and sparing surrounding critical structures and tissues.

Versa HD comes with 3D and 4D imaging features, which help radiologists visualize very small tumors and their movements. This feature largely helps in precisely targeting the tumor and positively impacting the overall treatment outcome.

Through its high-end features, such as advanced beam-shaping, superior imaging, and capability to deliver high-dose-rate radiation, Versa HD is especially helpful in the management of tumors located in critical areas.

How Does Versa HD Work?

Versa HD allows radiologists to treat a wide range of tumors throughout the body with extreme accuracy and efficacy. Through its flexibility and versatility, Versa HD aids radiologists in achieving positive clinical outcomes even in the case of the most complex cancer cases.

Radiation therapy on Versa HD begins with comprehensive imaging tests to precisely locate the tumor and study if it changes its position. If changes are observed, the system’s 6DOF couch is moved to realign the patient’s position for precise delivery of the radiation beams. Once the patient is in the right position, high-dose radiation is delivered to the tumor while limiting damage to the surrounding healthy tissues.

The treatment duration may vary from 10 to 20 minutes.

This radiation therapy platform facilitates the following radiotherapy modalities:

  • The machine can deliver very high-precision radiation treatments in the form of:
  • Volumetric Modulated Arc Therapy (VMAT/Rotational IMRT)
  • Stereotactic Body Radiotherapy (SBRT)
  • Image-Guided Radiotherapy (IGRT)
  • Intensity-Modulated Radiotherapy (IMRT)
  • Stereotactic Radiosurgery
  • Stereotactic Radiotherapy
  • Electron therapy

Advantages of Radiation Therapy with Versa HD

Versa HD helps specialists treat challenging cancers with sub-millimeter accuracy.

Through dual registration of target(s) and critical structures, Versa HD helps radiologists protect the critical structures close to the tumor while also achieving positive outcomes.

Versa HD can treat small and multiple targets in complex structures, namely the lungs.

Through high-dose-rate radiation delivery, Versa HD helps reduce the overall treatment duration.

Radiation therapy with Versa HD is a non-invasive procedure with relatively fewer treatment-related complications.

Frequently Asked Questions

This depends on the type and stage of cancer you are being treated for, along with the treatment plan that is recommended for you. Some may show side effects such as burning sensations, itching, and redness right away, whereas, for a few, it may take one to two weeks to start experiencing side effects.

Most of these side effects are temporary and can be easily managed. However, if they do not get better, you should immediately get in touch with your doctor.

Throughout the radiotherapy, you will need a lot of energy. So, you should avoid straining yourself. Simpler activities and exercises are fine. But it is better to avoid strenuous activities. You should also avoid planning weight loss during this period.

A few may experience a loss of appetite depending on the organ being treated; however, you cannot skip eating. Throughout the treatment, you should eat healthy and stay hydrated.

For information on diet and exercise, you can consult a certified onco-dietician who can help you with the right nutritional practices during and after treatment.

This again depends upon the type of cancer treated. Patients with brain cancer and head and neck cancer tend to lose hair. In most cases, this hair loss is temporary, and it grows back sometime after the treatment. However, in rare cases, if very high doses of radiation are used, the hair loss may be permanent.

You can always talk to your treating doctor about treatment-related side effects and the best ways to manage them.

There is a very small chance of this treatment causing secondary malignancies. However, regular follow-ups that will be scheduled after your treatment can help us reduce this risk for you.
