Abstract

|
|
|
To be investigated and measures to reduce the medical exposure of patients to change the Epidural Injection time Fluoroscopy Pulse Rate in this study. Was conducted in 50 patients who underwent surgery Epidural Injection performed by interventional care of Konkuk University Hospital from January to April 2013. The treatment time with the change of Pulse rate, is measured in minutes fluoroscopy time, and measured the area dose (μGym2) and depth dose (mGy). Using the Image J program, to measure the PSNR and SNR. The fluoroscopy time as a result surgery, there was no significance in the statistical analysis, and depth dose is 34.3 to 34.9%, was reduced from 35.8 to 38.7% the area dose. It is possible to reduce the appropriate Pulse rate, to reduce the dose without statistical analysis significance fluoroscopy time.
