Radiation exposure during percutaneous nephrolithotomy; Is there a risk of the patient and the operating team?
Background: The aim of this study was to calculate the radiation amount exposed during percutaneous nephrolithototomy (PCNL) and to make the urologists and other staff sensitive about the radiation risk they were exposed to. Materials and Methods: We measured the radiation exposure during 114 cases of PCNL performed. Thermoluminescent dosimeters (TLD) were placed between the operation table and...
متن کاملIs Weight-Based Adjustment of Automatic Exposure Control Necessary for the Reduction of Chest CT Radiation Dose?
OBJECTIVE To assess the effects of radiation dose reduction in the chest CT using a weight-based adjustment of the automatic exposure control (AEC) technique. MATERIALS AND METHODS With Institutional Review Board Approval, 60 patients (mean age, 59.1 years; M:F = 35:25) and 57 weight-matched patients (mean age, 52.3 years, M:F = 25:32) were scanned using a weight-adjusted AEC and non-weight-a...
متن کاملEffect of the CT table strap on radiation exposure and image quality during cervical spine CT.
BACKGROUND AND PURPOSE The CT table strap may impair shoulder lowering during cervical spine CT. The purpose of this investigation was to evaluate the effect of the CT table strap on radiation exposure and image quality during CT of the cervical spine. MATERIALS AND METHODS Patients undergoing cervical spine CT were prospectively randomized to having the CT table strap placed around the torso...
متن کاملAutomatic exposure control in CT: applications and limitations.
Tube current (mA) is one of the key technical scanning parameters for adjusting radiation dose in CT. To optimize radiation dose in CT, users can adjust mA either with manually selected mA values or with the application of automatic exposure control (AEC). The latter technique refers to automatic adaptation of mA on the basis of userspecified image quality and x-ray attenuation characteristics ...
متن کاملAutomatic Camera Exposure Control
It is commonplace to use digital video cameras in robotic applications. These cameras have built-in exposure control but they do not have any knowledge of the environment, the lens being used, the important areas of the image and do not always produce optimal image exposure. Therefore, it is desirable and often necessary to control the exposure off the camera. In this paper we present a scheme ...
