Hexapods Enable Precise 6-Axis Patient Positioning Couches For Radiotherapy

Radiation therapy is becoming a more mainstream way to treat tumors, not only because advances have made it more cost efficient and less intrusive than the classical treatments of surgery and chemotherapy but also because it performs better for many types of tumors.

External beam radiotherapy is mainly applied to tumors located in the head, breast, lung, and prostate.  Since the goal is to destroy the tumor cells without harming the healthy tissue around it, positioning the patient precisely relative to the beam is crucial. Based on the average size of human cells, a positioning resolution up to 0.03mm is recommended.
