Abstract

On radiographic examination of the vertebrae, the difference in the thickness of the thoracic vertebrae causes differences in the intensity of radiation reaching the detector so that the image quality and the dose received by the patient is different in the superior and inferior parts. The difference in radiation intensity can be reduced by using the heel effect anode technique. Anode Heel Effect is the intensity of radiation emitted from the cathode end of the x-ray tube is greater than that emitted at the anode end. The arrangement of the anode and cathode location is rarely considered so that the anode is more often in the inferior part resulting in a low density radiograph of the inferior part. In addition to affecting the image, of course, the anode hell effect affects the radiation dose produced because of the different density intensities. The research design is descriptive research with quantitative data types. The location of data collection was carried out at the Radiology Laboratory of the University of ‘Aisyiyah Yogyakarta. In this study, the whole body anthropomorphic panthom was used. The results of measurements of radiation dose and contrast with 70 kV and 10.5 mAs settings, obtained a higher dose and contrast value on thoracolumbar radiographic examination with the location of the cathode with an average dose rate of 55.93 µGy/s whereas if the cathode is in the distal the average radiation dose rate is 49.66 µGy/s. This is due to the anatomical shape of the thoracolumbar itself which is larger in the distal part than proximal so that the radiation intensity that reaches the detector is greater.
