TOPEX SRT 100 Superficial Radiotherapy System is designed to meet today's needs of the medical practitioner for the treatment of skin cancer.
TOPEX has developed a totally unique SRT product design through consultation with the medical community and expertise from within the x-ray therapy industry. This new design provides a system with compact size, mobility, automated set-up controls, modular component electrical assembly platforms and a wide range of motion for patient treatment flexibility. The SRT 100 represents a culmination of "bottom-up" product design effort resulting in significant improvements compared to older bulky component system designs.
Advanced System Design for Treating Skin Cancer:
• Large Range of Motion
The unique positioning arm design has both horizontal and vertical range of motion.
• Sitting or Recumbent Patient Positioning
Flexible movement allows for clinical treatment with patients in sitting or recumbent positions.
• Compact Mobile Design
The unique mobile design requires only a 29” x 30" footprint saving space while providing treatment location flexibility.
• Pre-Treatment "RAD" Check
This unique feature verifies dose delivery required before the patient is treated, and is displayed on the control console.
• Automatic Warm-up
There are four-programmed x-ray tube warm-up sequences that are selected based on the time of last exposure.
• Automatic Al Filter Change (Patent Pending)
Upon kV mA selection, the system automatically changes the Al Filter eliminating the need for filter storage and manual procedures.
• Precise Dose Delivery
There are two x-ray beam energies used specifically for the treatment of skin cancer. The x-ray tube focal spot is 1mm x 1mm and reduces the penumbral effect providing a more uniform treatment field.
• Replaceable Visual Applicator Safety Contact Shields
The system includes three applicators: 1.5cm, 3cm and 5cm. Each applicator safety contact shield is replaceable and provides for 1.27cm visual verification and clinical margin clearance of the treated area.
