To compare the amount of scatter produced by titanium plates versus Vitallium (Howmedica, Rutherford, NJ) plates. Software was also evaluated to determine its effectiveness in removing the scatter and clarifying the underlying anatomy.
Miniplating and microplating systems composed of Vitallium or titanium were placed on the nasal and frontal bones of three adult pig heads. A computerized axial tomography (CAT) scan was then performed and a three-dimensional CAT scan was reconstructed using MediCad software (MediCad Inc, Cedar Knolls, NJ). The amount of scatter for each plating system was quantitated using the MediCad software measuring tool. The scatter was removed and the three-dimensional CAT scan was reconstructed to assess the clarification of the underlying anatomy.
No scatter was found with either the miniplating or the microplating system composed of titanium. The Vitallium plates did show significant amount of scatter with the mini, micro, and micromesh system. Removal of the scatter resulted in slight improvement in the anatomic detail.
Titanium plating systems do not cause any radiation scatter. The MediCad software system allows removal of the scatter found with the Vitallium plates, which helps clarify the underlying anatomy.
比较钛板与维他灵板（Howmedica公司，新泽西州卢瑟福）产生的散射量。还对软件进行了评估，以确定其在去除散射和清晰显示深层解剖结构方面的有效性。
将由维他灵或钛制成的微型钢板和微型钢板系统放置在三个成年猪头的鼻骨和额骨上。然后进行计算机断层扫描（CAT），并使用MediCad软件（MediCad公司，新泽西州锡达诺尔斯）重建三维CAT扫描图像。使用MediCad软件测量工具对每个钢板系统的散射量进行定量。去除散射后，重建三维CAT扫描图像以评估深层解剖结构的清晰度。
由钛制成的微型钢板或微型钢板系统均未发现散射。维他灵板在微型、微型和微型网状系统中确实显示出大量散射。去除散射后，解剖细节略有改善。
钛钢板系统不会产生任何辐射散射。MediCad软件系统可以去除维他灵板产生的散射，这有助于清晰显示深层解剖结构。
