Assessment of an Instrument for Calibrating
Dose Area Product (DAP) Meters
Radcal Corporation (California, USA) have developed a "Patient
Dose Calibrator", (PDC) designed to allow quick and easy
calibration checks of installed DAP meters.
The PDC method of calibration is significantly quicker than our
traditional method, and allows a full check of the DAP meter
calibration over a range of field sizes and shapes and beam
quaities. |
| The Route To Patient Dose Control |
| |
|
|
| • |
The PDC solves much publicized problems relating to variation of DAP, Patient Dose system and AEC calibration. |
|
| • |
Measures DAP, DAP-rate, Dose and Dose-rate. |
| • |
Ideally suited to aid the setting of reference doses. |
| • |
Widespread use of the PDC by equipment manufacuturers, x-ray service organizations, physicists and radiation technologists will help acheive consistent patient dose levels. |
| • |
Ion chamber performance. |
| • |
Optical and radiographic alignment markers. |
| • |
Simple to use with optional computer control. |
 |
• DAP and dose linearity with dose and field size.
• Sensitivity testing.
• DAP and dose calibration at the patient plane or at a reference distance.
|
 |
• Entrance surface dose calibration for different examinations using a phantom.
• Establishing examination related reference DAP and dose levels. |
 |
• Image receptor dose measurement.
• AEC linearity testing. |  |
