''This article discusses CT radiation dose, the measurement of CT dose, and CT image quality. The most commonly used dose descriptor is CT dose index, which represents the dose to a location (e.g., depth) in a scanned volume from a complete series of ...'

''Screening heavy smokers with low-dose computer tomography (CT) instead of X-rays can reduce deaths from lung cancer by 20 percent, a massive US study released Thursday shows. Previous studies have shown that helical CT scanning can identify small ...'

''To compare the visibility of anatomic structures in direct-detector chest radiographs acquired with different tube voltages at equal effective doses to the ...'

''Dentists have been warned not to buy a handheld x-ray machine which exposes patients to 10 times the recommended dose of radiation. The cheap imported devices could also pose a significant risk to dentists and nurses, health officials said. The ...'

''PURPOSE: To determine the radiation dose to radiologists who perform computed tomographic (CT) fluoroscopic interventional procedures by using a quick-check method and a low-milliampere technique. MATERIALS AND METHODS: Two hundred twenty CT ...'

''X-ray computed tomography (CT) is one of the diagnostic procedures that can cause relatively high radiation exposure to the patient. In the last two decades, the increasing use of CT in clinical practice and the relatively high doses delivered to the ...'

''The plan for broad use of X-ray body scanners to detect bombs or weapons under airline passengers' clothes has rekindled a debate about the safety of delivering small doses of radiation to millions of people - a process some experts say is certain to ...'

''Scientists have developed a way to produce three-dimensional X-ray images of the breast at a radiation dose that is lower than the 2D radiographies used in clinics today. The new method enables the production of 3D diagnostic computed tomography (CT) ...'

''For decades GE Healthcare has invested in leading, state of the art technology for significantly lowering dose in computed tomography (CT) procedures. GE Healthcare's exclusive ASiR†(adaptive statistical iterative reconstruction) low dose reconstruction ...'

''There's a new modality in radiology, one that takes advantage of digital radiography (DR) and reflects the tenets of value-based medicine low cost, high information and low radiation dose to patients. The FDA has not cleared this modality, but ...'
