Accurate high activity brachytherapy measurements present new challenges in Radiation Therapy, the CRC-15BT easily overcomes these challenges.
Both HDR and LDR brachytherapy sources are quickly and precisely measured by the CRC®-15BT.
The console of the CRC®-15BT is designed for ease and efficiency. There are 14 nuclide keys that can be programmed to meet the users needs. The unit has a large LCD display that will show the isotope name, activity (in Ci or U) and calibration number. A custom alphanumeric keyboard drives all of the menus and functions.
The chamber of the CRC®-15BT has 1/8” (3.2 mm) mechanically reinforced lead shielding. The chamber is a sealed thin wall, deep well design with 2.5 atmospheres of Argon gas and a 500 V bias in order to achieve optimal response time (within 2 seconds) without temperature or pressure corrections.
ADCL Calibration is available with the CRC®-15BT to ensure maximum accuracy. Calibrated with the specific brachytherapy source(s) utilized in your department, activity can be measured precisely in either Curies (Ci) or Air Kerma strength (U).
The CRC®-15BT software is a menu driven design that will allow the user to move rapidly through all of the system functions. The Daily QC protocol will perform zero adjust, background subtraction, system test, accuracy (with a deviation percentage) and constancy. The nuclide library is programmed with more than 80 nuclides and half-lives, plus available space for 10 additional nuclides. The system memory can also support up to 20 brachytherapy sources with isotope name, calibration number, Air Kerma strength and ADCL factor.
