Abstract

Background: In the CTA examination of cerebral angiography at the Radiology Installation of Salatiga Hospital, the flow rate used was 5 ml/s, bolus tracking contrast media was placed in 2 different places, some radiographers used the internal carotid artery and some used the aortic arch as an indicator of ROI tracking. Image acquisition is done by adjusting the scan delay post injection of contrast media and pre bolus tracking, so that the difference in the placement of the tracking affects the scan delay time and the dose given to the patient. The purpose of this study is to determine the location of accurate tracking in terms of image information and radiation dose given to the patient.Methods: This type of research is descriptive with qualitative data. The research object is the patient who performs Cerebral CTA examination with tracking location on the interna carotid artery(ICA) and aortic arch. The research subjects were 2 radiographers and 1 radiologist. Data collection was done by interview observation method.Results: Research shows that in Cerebral CTA examination using ROI tracking in the ICA area, there is a risk of contrast media entering the blood vessels if the scan delay time setting is not right, while the ROI tracking setting in the aortic arch is safer if the patient moves the tracking location is still around blood vessels but the radiation given to the patient tends to be larger as the scanning area increasesConclusions: The use of tracking ROI in the area of the internal carotid artery and aortic arch on CTA Cerebral examination can be used according to the radiographer's expertise in finding these blood vessels, the use of the right scan delay time affects the scanning results produced.

Abstract

Background: Phantom radiology is used as a medium of learning as a substitute for human bones. In its use this phantom radiology has economic value high enough to be an obstacle to the learning process. Therefore, it is necessary to make a phantom with basic materials that are easily accessible and have the same density value as human bones.Methods: the method used throughout this study is through an experimental approach. The research stage involves testing the density of wood by comparing the density value of the sample used, determining the composition of the mixture between wood, contrast media and adhesives that produces phantom with the density that most closely resembles bone phantom.Results: From the results of the research, the density value of the anthropomorphic phantom humerus was 9034, and the information obtained for the density value of the four wood phantoms with basal values. Based on the results of the calculation of the density value obtained the highest value on phantom 1 with a density value of 12775, phantom with the lowest density value of 7682, namely the second phantom, the value of wood phantom density is quite close to the density value of anthropomorphic humerus phantom, namely phantom 3 with a density of 8986 and Phantom 4 density which is slightly above the wood Phantom 2 density value is 7773.Conclusions: In this study to produce wood phantom with a density that resembles bone phantom is carried out with local wood base material mixed with BaSO4 contrast media, so that the average density value is 8986 close to the density value in anthropomorphic bone phantom humerus.
