COLLIMATION VS CONVERSION

Limitations in Traditional Radiation Delivery

Traditional radiotherapy devices incorporate a diverging beam. This type of radiation beam is characterized by its decreasing intensity as the distance from the source increases. To achieve a thin beam, a collimator is used to limit the beam size. The beam continues to diverge and therefore, its intensity is low and decreases with distance.

A NOVEL APPROACH

The Lens Makes the Difference

The Convergent approach to delivering radiation therapy is fundamentally new because it leverages off-the-shelf X-ray tubes that deliver kV radiation in a converging beam. The Convergent Beam Technology incorporates a lens design that collects X-rays at a finite solid angle and converges them toward the target location. This convergence increases the energy density and delivers a relatively high dose at the target location, while the area farther from the target receives a lower dose.

MORE THERAPEUTIC DOSE

100x Lower Energy than Linear Accelerators

The lens simultaneously removes low energy photons that the patient’s skin would absorb. The convergence increases the therapeutic dose delivered at the tumor location, while the organs in the vicinity of the tumor receive a very low dose or no dose at all. The converging technology enables the use of photon energy X-rays 100 times lower than traditional linear accelerators.

REDUCED EXPOSURE

Limitless Possibilities

With the Convergent Beam Technology, the possibilities are limitless.

  • This innovative use of a standard imaging X-ray source opens a new form factor to radiotherapy systems, resulting in a cost-effective and compact design.
  • Latest studies show high potential of precise radiotherapy treatment for in-depth cancer tumors.
  • The design flexibility of the CRnR system allows a modular installation in almost every clinical setup while maintaining safety and accuracy.
