MT-CRS-3D CRS 3D RADIATION BEAM SCANNERThe CRS Radiation Beam Scanner is a low-cost, lightweight water phantom for comprehensive QA testing of external beam quality. Its fully modular design allows for the addition of a number of add-on accessories, including a Film Densitometer. The software package, included, allows for easy, intuitive scan data analysis including beam flatness, symmetry, percent depth dose, isodose curves, TMR tables, and more.

The system consists of precision motorized drive mechanisms for 3D beam mapping, a water tank, a dual channel electrometer, and a comprehensive software package. All components are made of the highest quality materials available including anodized aluminum, stainless steel, plated steel, and high impact plastics. All the mechanical drives and scanning mechanisms are precision machined and designed for long life and trouble free operation in ordinary tap water.

Variable scanning speeds of 0 to 150mm/sec make this one of the fastest scanners on the market today. Due to the high-precision stepping motors, a high degree of positioning accuracy and reproducibility are assured at any scanning speed. The system will perform a 20cm scan in less than 10 seconds with 800 data points with better than 0.13mm accuracy. The external electrometer for single-channel or dual-channel applications collects measurement signals from the ion chambers and transmits them directly to the PC. All scanning functions are controlled via the PC from the convenience of the control room. Thick transmission cables and cable clutter is eliminated.

The water-scanning and film-scanning software is designed for manual and fully-automated beam data acquisition for both photon and electron energies. The comprehensive software package offers measurement and analysis of beam profiles and depth dose including flatness, symmetry, PDD, generation of isodose curves, and TMR (with optional lift table). The software also allows for direct interfacing and data transfer to numerous treatment planning systems.

The system is available in two dimensional and three dimensional configurations to suit any facility’s needs and budget.

Installation and training available.

Features:

  • Rugged construction: Most parts are anodized aluminum or plated steel, designed to withstand the rigors of commercial shipping and to prevent deterioration while operating in ordinary tap water.
     
  • Inexpensive, modular design: Exchange components of the basic 2D scanner. Quickly converts to a 3D scanner, a densitometer, or an in-air scanning bridge. Unnecessary duplication of parts keeps the system cost to a minimum.
     
  • Efficient and portable: Lightweight, minimum size, simple assembly and disassembly, rugged construction and durable shipping containers make the system easily and safely transportable. It is accurate, reliable, and easy to operate. Complete product and operator manuals are supplied with each unit.
  • Simple setup: Place the tank on the treatment couch and fill with water. Two large adjusting screws assemble the separate scanning mechanism and level it with the water surface. No tools required. Attach the motor and data cables to the external electrometer placed inside the treatment room. Only one extension cable is required to connect to the computer outside the room.
     
  • Universally adaptable: Minor variations to key components allow the system to function with a variety of existing equipment and offer the flexibility to operate within individual requirements. Control it with any IBM-compatible PC, including notebook and laptop models. The system interfaces with most treatment planning systems and can be made to match others on request.
     
  • Excellent value: Very affordable and portable, the CRS 3D scanner is designed to provide years of dependable service with a minimum of maintenance.
