Performance Evaluation and X-ray Dose Quantification for Various Scanning Protocols of the GE eXplore 120 Micro-CT The aim of this paper was to evaluate the performance of the General Electric eXplore 120 micro-CT regarding image quality and delivered dose of several pr... Bretin, F,Warnock, ...
A meta-analysis of the published literature on low-dose occupational radiation exposure and leukemia risk was also conducted. Results The incidence rates of leukemia in X-ray workers and the control group were 6.70 and 3.39 per 100,000 person-years, respectively. Among X-ray workers, the ...
Radiation was administered by using the Precision XRAD 225Cx (Precision, North Branford, CT) with X-ray setting to 225kvp, 13 mA, cone 4 × 4 cm, beam time 267.78 s for 10-Gy treatment, while twice 10-Gy administration for 20-Gy treatment. Figure 7 Rat irradiation, ...
In cone-beam computed tomography (CBCT) for image-guided radiation therapy (IGRT) of the head, we evaluated the exposure dose reduction effect to the crystalline lens and position-matching accuracy by narrowing one side (X2) of the X-ray aperture (blade) in the X-direction. We defined the...
Single-photon emission computed tomography combined with X-ray computed tomography (SPECT/CT) improves diagnostic accuracy by allowing better localization
A chest X-ray is the first tool used in approaches to RP. Radiographic lung damage sees in lung volumes irradiated at doses under 20 Gy. Newer techniques like VMAT or IMRT have the potential to deliver lower doses of radiation distributed in lung volumes. V5, V10, and V15 dose ...
