T his 2D water-scanning phantom was developed by CRS based upon the realization that physicists often need a convenient, full-function quality control device that meets all the requirements for external beam quality control and calibration – without the bulk, cost and complexity of large water phantoms.
The QuickScan is a smaller version of the full-size CRS 2-axis scanner, specifically designed for use with the MED-TEC water tanks. Other tanks of similar dimensions may also be used.
The QuickScan employs the same durable, high-precision mechanical components and electronic assemblies as the regular CRS scanners. However, the drive mechanisms are scaled down to suit smaller tanks, making the system ideal for consulting physicists who need a portable system.
A dedicated QuickScan software package caters to the needs of the physicist for quick, accurate, and easy quality checks of radiation therapy treatment machines.
Depth dose, flatness, symmetry, cumulative display of continuously-scanned profiles (to allow real-time adjustments of the radiation beam in an oscilloscope-type fashion), as well as positioning of the probe to any point within the tank for manual measurement, are software-supported. Beam data can be stored and archived for later retrieval and comparison with currently-displayed beams. A unique dosimetry technique allows for dynamic/virtual wedges to be scanned using a single probe moving at high speed.
The QuickScan is indeed quick: the maximum scanning speed is 150mm/second. Maximum scanning dimensions are 285mm horizontally and 215mm vertically. The QuickScan weighs only 11kg, including an empty MT-100 water tank. It is also convenient – no tools are necessary to mount the scanning mechanism onto the tank. The tank does not have to be leveled on the treatment couch, since the scanning mechanism is leveled on top of the water tank. This eliminates an additional leveling platform for the tank. When not in use, the QuickScan mechanism can be quickly disassembled and safely stored in the special container, provided.
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: QuickScan utilizes components of the basic CRS 3D and 2D scanners. Unnecessary duplication of parts keep 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, QuickScan is designed to provide years of dependable service with a minimum of maintenance.
