LOGISTIC BENEFITS - COMPACTNESS WITH UPRIGHT CHAIR Or robotic couch
Upright patient positioning system features
"LEO CancerCare is the most advanced chair, upright with rotational capability"
The Linear Beam ERHA system is capable of proton beam size significantly smaller than with legacy systems, offering the best-in-class proton spot size, therefore providing the maximum realization of treatment conformity for static and moving tumors.

In addition, unlike other systems, the ERHA ultra-fast energy changes serve to preserve treatment quality even for moving tumors.
The use of a small spot size in PBS and IMPT is especially important, as it enables the beam to conform closely to the tumor’s shape, ensuring that the highest dose is concentrated within the cancerous tissue while minimizing exposure to surrounding healthy tissues.

This high level of precision, combined with the Bragg peak effect, reduces the risk of toxicities and improves the therapeutic window, making proton therapy an invaluable tool in the pursuit of safer and more effective cancer treatments.
