| Research Abstract |
Comparisons of focal-spot size measurements with a direct-exposure X-ray film and an imaging plate (IP) were carried out for the slit and star resolution pattern camera techniques. As a result, compared with the direct-exposure X-ray film method, the measurements with IP were slightly large for large and small focal spots although the measurement of the micro focal-spot size was overestimated extending the tolerance level due to the sampling. For the star pattern camera technique, the differences by two kinds of detectors were little. Therefore, it was thought that the measurement of the focal-spot size with IP would become practical for the large and small focal spots if this method were aimed at the quality control in medical facilities.
