PURPOSE: The purpose of this study was to develop PC-based perfusion software using Microsoft Windows. This software was developed to reformat perfusion maps including CBV (Cerebral Blood Volume), MTT (Mean Transit Time), and CBF (Cerebral Blood Flow) maps and to analyze perfusion quantitatively. MATERIALS AND METHODS: Windows-based perfusion software was developed using IDL (Interactive Data Language) as the development tool. The perfusion software was written to load the source image from dynamic first-pass cerebral perfusion CT and to reformat perfusion maps. Mean perfusion values in gray matter and white matter were calculated and compared to previously calculated data reported in literature. RESULTS: This software reformatted first pass perfusion maps in a user-friendly PC and calculated CBV, MTT, and CBF values. The values were within the normal range of the mean values when compared to previous studies. CONCLUSION: CT perfusion maps and perfusion values can be obtained by using the newly developed PC-based perfusion software. Further study is needed to achieve more precise values. However, we believe that in the future, this program may be used in various clinical settings.

8.The Normal Value of Amplitude of Accommodation in Koreans.
Journal of the Korean Ophthalmological Society 1979;20(2):153-157
The amplitude of accommodation of 490 normal Koreans aged 6 to 70 was measured with minus lens to blur technique. Duane's single, fine thread target was used. The result was divided into 13 age-groups as follows: 1. The age group of 6 to 10: The range was 16.25 D to 11.50 D, the median 14.50 D and mean 14.55 D. 2. The age group of 11 to 15: The range was 16.25 D to 11.00 D, the median 12.5O D and the mean l2.36 D. 3. The age group 16 to 20: The range was 13.5O D to 8.75 D, the median 10.50 D and the mean 10.75 D. 4. The age group of 21 to 25: The range was 12.00 D to 5.5O D, the median 9.00 D and the mean 8.86 D. 5. The age group of 26 to 30: The range was 9.25 D to 6.00 D, the median 7.5O D and the mean 7.25 D. 6. The age group of 31 to 35; The range was 7.5O D to 4.75 D, the median 6.00 D and the mean 6.10 D. 7. The age group of 36 to 40: The range was 6.00 D to 4.00 D, the median 5.00 D and the mean 4.9O D. 8. The age group of 41 to 45: The range was 5.25 D to 2.00 D, the median 3.75 D and the mean 3.81 D. 9. The age group of 46 to 50: The range was 4.75 D to 1.75 D, the median 2.75 D and the mean 2.84 D. 10. The age group of 51 to 55: The range was 3.00 D to 1.00 D, the median 2.00 D and the mean 2.06 D. 11. The age group of 56 to 60: The range was 2.00 D to 0.5O D, the median 1.50 D and the mean 1.34 D. 12. The age group of 61 to 65. The range was 1.55 to 0.00 D, the median 0.75 D and the mean 0.72 D. 13. The age group of 66 to 70. The range was 0.5O D to 0.00 D, the median 0.25 D and the mean 0.21 D. Amplitude of accommodation is found to be gradually decreasing with the advancing age and no sudden decrease was noted. The results are similar to those of Donder's. Compared with Duane's, my results showed a slightly higher value below age of 10 and slightly lower value above age of 15.

The quality correction in the air kerma dosimetry for Ir-192 using farmer type ionization chambers calibrated by Co-60 quality is required. In this study we determined quality factor (kappa u) of two ionization chambers of PTW-N30001 and N23333 for Ir-192 source using dosimetric method. The quality factors for energy spectrum of microSelectron were determined as kappa u=1.016 and 1.017 for PTW-N30001 and N23333 ionization chambers respectively. We applied quality factors in air kerma dosimetry for microSelectron source and compared with reference values. As a results we found that the differences between reference air kerma rate and measured it with and without quality correction were about -0.5% and -2.0% respectively.
