Abstract
High kilovoltage radiography had its beginning with supervoltage technique and is presently accomplished with the 350 kV Chest X-Ray System. The physical reasons to explain the improved visibility with this technique are: (a) absorption coefficients of bone and soft tissue, (b) more uniform bone visibility, (c) x-ray spectrum, (d) visual responses, and (e) depth resolution. In our study, 350 kV and 120 kV chest x-ray techniques are compared by evaluating some 15 parameters. Based on our data and the results of previous large clinical studies, a list of disadvantages and advantages if offered. The entrance dose for an average 350 kV PA chest radiograph is 8 mR, which is about 1/3 that with 90 kV technique.
