ZDi has created the only product line (Z-System) which ensures that a patient is accurately positioned within 2mm of the original treatment plan, thereby assuring precise dose delivery to the tumor target site. The system works through a series of interlocking units operating in conjunction with the foam immobilization mold to securely position the patient for each treatment. The Z-System is constructed with a universal indexing system to fit any treatment or CT table top. With accuracy, consistency, and efficiency in mind, the system was created to standardize and optimize Proton Therapy and conventional Radiation Therapy treatments.


Positioning the industry of patient immobilization for proton and conventional radiation therapy to establish the world-wide standard in treatment techniques and consumer quality.
