Abstract

The purposes of this study were to invent a pelvic x-ray imaging device in the Inlet and outlet positions, and to determine the optimal operating distance of the device as well as evaluation of device used by students and radiological technologists. We studied using pelvis phantom in the pelvis inlet and outlet x-ray to determine the criteria. Then let the third-year radiological technology students (n=30) and the radiological technologists at Songklanagarind Hospital (n=9) used the innovation with pelvis phantom to compare the repeated rate before and after using the innovation along with a satisfaction assessment after use the device. We found that the setting criteria of this innovation for pelvis inlet x-ray were the top border at 1 inch above iliac crest and the bottom border at level of groin or 5 inches under anterior superior iliac spine (ASIS). For pelvis outlet x-ray is sets the top border at 1 inch above Iliac crest and the bottom border at 1 inch below the groin. Then set the center ray between the top and bottom border of the device. After the radiological technologists have used the device with pelvis phantom, the results showed that the repeated rate of pelvis inlet x-ray decreased from 64.00% to 0% and pelvis outlet x-ray decreased from 47.06% to 0% with cover the desired area.
