| Abstract: | Objective To study the principle & application of linear scanning direct digital Xray radiography and its practical value.Methods The applicability of linear scanning for multiwire proportional chamber direct digital Xray radiography were analysed. Results The interference of scattered rays as eliminated by linear scanning imaging technique. The later had high detection sensitivity and density resolution.Conclusion Linear scanning imaging technique is suitable for all digital Xray radiography except the dynamic radiography .And it develops a bright future in gradually accomplishing the digitization of conventional Xray radiography. |
