[OA135] Current pediatric radiation doses from a computed tomography (CT) dose registry

Radiation Doses from Computed tomography in Iraq

Radiation doses to Patient during CT scanner and the radiological risk are significant. Patient dose survey has been conducted toinvestigate the Iraq patient radiation dosesreceived in CT scanners in order to established reference dose levels. These doses are Entrance Surface Dose (ESD),computed tomography dose index(CTDI)), and dose length product (DLP). Two CT scanner were investigated in thi...

Estimating the Radiation-Induced Cancer Risks in Pediatric Computed Tomography

Introduction One of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. Therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...

Template-Driven Computed Tomography Radiation Dose Reporting

Imaging dose from cone beam computed tomography in radiation therapy.

Imaging dose in radiation therapy has traditionally been ignored due to its low magnitude and frequency in comparison to therapeutic dose used to treat patients. The advent of modern, volumetric, imaging modalities, often as an integral part of linear accelerators, has facilitated the implementation of image-guided radiation therapy (IGRT), which is often accomplished by daily imaging of patien...

Patient radiation dose and protection from cone-beam computed tomography

After over one decade development, cone beam computed tomography (CBCT) has been widely accepted for clinical application in almost every field of dentistry. Meanwhile, the radiation dose of CBCT to patient has also caused broad concern. According to the literature, the effective radiation doses of CBCTs in nowadays market fall into a considerably wide range that is from 19 µSv to 1073 µSv and ...
