Radiation dose reduction using a CdZnTe-based computed tomography system: Comparison to flat-panel detectors

Comparison of radiation dose in Multidetector computed tomography and Flat-panel computed tomography for imaging of the wrist

Dose Reduction Methods in Chest Computed Tomography

Introduction: Computed tomography is one of the most powerful tools for investigating thorax disease, because it shows progression of lung disease much clearer than chest radiography. Technical advances in CT scanners have led to some abilities for CT scanners such as coverage of larger volume, lower noise and ability for acquiring image in one respiratory phase. However, this will be accompani...

Radiation dose survey in a paediatric cardiac catheterisation laboratory equipped with flat-panel detectors.

Flat-panel X-ray detectors for fluoroscopy represent a modern imaging equipment that is being implemented in paediatric cardiac catheterisation laboratories. Infants and children represent a group of patients with a high radiosensitivity. A survey of 273 (126 diagnostic and 147 therapeutic) paediatric catheterisations was performed to investigate the radiation doses delivered by the new X-ray s...

Radiation dose evaluation in 3D rotation angiography and cone-beam computed tomography with a flat panel detector.

The aim of this study was to evaluate radiation dose in patients undergoing three-dimensional rotation angiography (3DRA) and cone-beam computed tomography (CBCT) using a flat panel detector (FPD). Radiation doses were measured for angiography equipment using small silicon-photodiode dosimeters that were implanted in various positions in tissues and organs within an anthropomorphic phantom of a...

Radiation dose from cardiac computed tomography before and after implementation of radiation dose-reduction techniques.

CONTEXT Cardiac computed tomography angiography (CCTA) can accurately diagnose coronary artery disease, but radiation dose from this procedure is of concern. OBJECTIVES To determine whether a collaborative radiation dose-reduction program would be associated with reduced radiation dose in patients undergoing CCTA in a statewide registry over a 1-year period and to define its effect on image q...
