| Abstract:: |
| On the basis of phantom experiments, patient doses from radiography at different tube voltages were estimated, and effect of elevated tube voltages on quality of film image was studied. The results show that the use of high voltage in chest radiography is conducive to reduction of patient dose as compared with lower voltage, and it has major advantages in obtaining more diagnostic information and facilitating detection of lesions in rib shadow area and mediastinal area. Besides, the high voltage technique is instrumental in lengthening the service life of X-ray tubes. |
