- W4307737245 abstract "When compared to other radiological examinations, computed tomography has a significantly higher radiation exposure and employs ionizing radiation to make an image of a slice or cut of tissue and to learn about the patient's sickness. The current studies' objectives were to determine image quality and radiation dose from the 16-slice Philips CT scanner in order to identify the radiation dose delivered accuracy and the acceptable image quality parameter of CT scanner. The current investigation was carried out using quality assurance CT phantom, Image software, CT dosimeters PMMA phantom coupled with a 100mm pencil chamber. The image quality performance parameters that were tested were image noise, uniformity, CT number accuracy, and resolution. The radiation dose performance parameters that were evaluated were volume computed tomography dose index (CTDIvol), weighed computed tomography dose index (CTDIw), and dose length product (DLP). The results of the present study were measured CTDIvol was 10.01mGy, and the displayed was CTDIvol was 10.2mGy for the head scan technique, 5.8mGy, and 6.1 mGy for the body scan technique respectively. The image quality parameters were 4.4HU, 2.3HU, and 10 8HU for uniformity, contrast to noise ratio, and CT number accuracy for PMMA Quality assurance phantom respectively. The image quality parameter tests were accepted because they were within the tolerance values and the CT radiation dose parameters were not accepted within the international dose reference level. All CT scanners must pass the CT quality control test with respect to image quality and radiation dose for their performance to be improved." @default.
