Estimation of Operator Dose by Dose Area Product Meter

Japanese Journal of Radiological Technology, 2006
Because of the more advanced and more complex procedures in interventional radiology (IVR), longer treatment times have become necessary. Therefore, it is important to determine the exposure doses received by operators and patients. Operator doses arising from the use of X-rays are mainly due to scattered radiation.

Decadal Changes in Institutional Diagnostic Reference Levels for X-Ray Angiography: A Retrospective Comparative Study [PDF]

Journal of Imaging
Angiography is a key imaging modality for the diagnosis and treatment of vascular diseases, and the growing sophistication of interventional procedures has heightened the need for radiation dose optimization. Diagnostic Reference Levels (DRLs) are widely

No reduction of radiation dose following the introduction of dose–area product measurement in endoscopic retrograde cholangiopancreatography

European Journal of Gastroenterology & Hepatology, 2015
During radiological examinations such as endoscopic retrograde cholangiopancreatography (ERCP), it is recommended to record the dose-area product (DAP) to reduce the patient's and the physician's exposure to ionizing radiation. However, the effect of DAP measurement on the total radiation dose in ERCP procedures has never been assessed.This study ...

Measurement of dose‐area product with GafChromic XR Type R film

Journal of Applied Clinical Medical Physics, 2005
Many of the newer X‐ray machines are equipped with electronic means to provide dose–area product (DAP) information. For machines without that ability, an alternative method is to record radiation on a film that can handle a large amount of cumulative exposure. The use of GafChromic XR Type R film was investigated for this purpose by placing it at the X‐

Characteristic Evaluation and Clinical Usefulness of Dose Area Product Meter at Radiography

Japanese Journal of Radiological Technology, 2011
Philips DigitalDiagnost, a digital radiographic system mounting flat panel detector (FPD), can display dose area data (DiDi dose) calculated by examination parameters. We evaluated its fundamental characteristics and compared the values of DiDi dose andactual measured data obtained by the area dose product meter (PD-4100L). Tendency of varied values of
