Background: Application of Dose-area product (DAP) quantity has been increased in the clinical practice. DAP is relatively easy to measure. DAP has been shown to correlate well with the total energy imparted to the patient, which is related to the effective dose. Material and Methods: In this study, measurements of DAP were carried out in a sample of 421 adult patients who underwent convention...

Computed Tomography (CT) scans promote a higher dose deposition than conventional radiology exams. These tests contribute significantly to the increase in patient and collective dose, being public health concern worldwide.

background: the shielding methods in radiotherapy due to delivering an accurate radiation dose to cancer tissues and avoiding unnecessary dose to normal tissues are very important. these methods include lead standard blocks, individual molding and multi leaf collimator (mlc). the mlc method is not still common in iran radiotherapy centers. individual molding is better than the lead block shield...

PURPOSE To present the experience in patient dose management and the development of an online audit tool for digital radiography. MATERIALS AND METHODS Several tools have been developed to extract the information contained in the DICOM header of digital images, collect radiographic parameters, calculate patient entrance doses and other related parameters, and audit image quality. RESULTS Th...

The use of image-guided interventional radiological techniques is increasing in prevalence and complexity. Imaging system developments have helped improve the information available to interventionalists to plan and guide procedures. Information on doses to patients resulting from alternative imaging techniques or protocols is useful for both the process of justifying particular procedures and i...

CONTEXT Computed tomography (CT) exams are increasingly common and account for a significant portion of individuals' mounting exposure to medical radiation. OBJECTIVE To explore issues surrounding patient radiation dose, including techniques for minimizing dose and the feasibility of tracking lifetime exposure to medical radiation from CT and other imaging exams. METHODS The authors conduct...
