This study was function experiment or inspection of diagnosis x-ray unit at the hospital. It's how many changes tube voltage, tube current, DOSE value through the experiment depending on temperature increasing. The study want to know whether which parameter shown out of range or not how about image quality and so on. Increasing tube current and DOSE were not only too many radiation to the patient and radiation workers and make bad images but also the tube should be damaged by heat. This study was recommended proper exposure at intervals of seconds because passed inspection, reduced radiations for patient and the tube used long term. This results in the hospital`s finances will be very helpful.
