- Special x-ray applicators that provide visual verification and margin clearance of the treated areas, including safety disposal tips.
- Automatic Warm-Up Modes
- Automatic Filter Selection
- Standard Wall Socket Plug-in Operation
- Specially designed control console for physicists and service technicians providing integrated safety and back-up timer controls, automatic system conditioning procedures, calibration, x-ray output verification and system parameters including last treatment status information.

- Compact mobile design with a 29"X30" footprint and unique scissor x-ray tube arm movements providing a large range of motion for patient access and treatment.
TOPEX technology is based on several needs requirements. The most prevalent is the need for a current dedicated skin cancer treatment device. There have been little to no new developments in superficial radiation therapy systems in recent years. The earlier devices were developed to provide therapeutic services for treating a number of cancer conditions and have been replaced by other modalities and/or specialized procedures. However, the primary use for these older systems today is skin cancer treatment. Consequently, many systems still in operation are antiquated by today's standards in terms of system operation, long set-up procedures, large space requirements, parts availability and ongoing costly maintenance to insure continued operation and that product safety requirements are met for both the patient and clinician.
