A comparative investigation on the resolution of angio-tomography and cut-film changer technique, standard views and direct geometrical radiographic magnification were carried out, using a phantom. Catheters of varying calibre and contrast were tested. The most significant result was the finding that lower concentrations of contrast were necessary to demonstrate small vessels or catheters when using angio-tomography or magnification, than with conventional techniques. It was also shown that angio-tomography and a magnification technique are able to show smaller and less contrasty vessels.
使用体模对血管断层摄影术与断层换片技术、标准视图及直接几何射线照相放大的分辨率进行了对比研究。测试了不同管径和对比度的导管。最显著的结果是发现，与传统技术相比，使用血管断层摄影术或放大技术时，显示小血管或导管所需的造影剂浓度更低。研究还表明，血管断层摄影术和放大技术能够显示更小且对比度更低的血管。
