radiation doseBackground: Radiation dose administration and its associated risks when performing computed tomography (CT) has been increasingly scrutinised in the recent past. The absorbed dose to organs and tissue in CT is high, therefore risks must be outweighed by benefit when considering a CT ...
in Cleveland, OH. Researchers evaluated 29 patients who underwent prospectively-gated 100 kV whole chest CT for preoperative cardiothoracic surgery. The meanradiation dosewas determined and compared to a group of regular dose prospectively-gated exams. "The most significant aspect of our...

Thin-section, high-resolution (1.0/1.5 mm thick slices), low-dose chest CT scans were performed in 55 infants and children. The studies were carried out with 1-and 2-s scan (data acquisition) times using a high-resolution (bone) algorithm. Although there was some motion artifact, the stu...

Objective To assess the program of low dose chest CT screening with iterative reconstruction technique(iDose4).Methods Totally 120 subjects who underwent chest CT screening were divided into 3 groups according to body mass index(BMI): Group A(BMI≤22),group B(22BMI26) and group C(BMI≥26)...
Fig. 1. (a, standard dose image; b, low dose image) 75 year-old-male (body weight 46 kg) who had a chest CT examination for a suspected lung tumor in the right upper lobe. Visualization of a tumor with partially irregular margin and spicula (arrow) is clear in both images. Downloa...
Three CT scans were obtained at each dose level using both rings. Regions of interest for each material in the test object scans were automatically extracted. The Hounsfield unit values of each material using weighted filtered back projection (WFBP) at 1.5 mGy was used as the reference value ...
试验详情 试验目的 This study aims to develop a novel ultra-low dose chest CT technology for use in Hereditary Hemorrhagic Teleangiectasia (HHT) patients and to determine the lowest possible radiation dose that is achievable without sacrificing the diagnostic quality. 试验详情 ...
