Using an asymmetrical screen-film-grid combination with an ITC-VHC special grid (Kodak), the effect of the individual components was evaluated with regard to detail in the lungs and mediastinum as well as patient dose.
The system was compared with the Curix Ortho screen film system (Agfa L-film) using phantoms and 62 patients in an intensive care unit. The results were analysed by three independent observers. Dose measurements on phantoms were carried out with a WD 10 (Wellhoefer) dosimeter and with a thermoluminescence dosimeter for patients.
Both phantom and patient images showed improved demonstration of mediastinal structures with similar details of lung structure. Details in the peripheral lungs are significantly better shown with the ITC-VHC system with the special grid than they are without the grid. However, there is an increase about three to four times in radiation dose when using the grid.
Our trial shows that the use of the ITC-VHC grid system is to be recommended for routine clinical use because of the better demonstration of details, but one must be aware of the increased radiation dose to the patient.
使用非对称屏-片-格栅组合以及ITC-VHC特殊格栅（柯达），评估各个组件在肺部和纵隔细节以及患者剂量方面的效果。
使用模型和重症监护病房的62名患者，将该系统与Curix Ortho屏片系统（爱克发L胶片）进行比较。结果由三名独立观察者进行分析。使用WD 10（韦尔霍费尔）剂量仪对模型进行剂量测量，对患者使用热释光剂量仪进行测量。
模型和患者图像均显示纵隔结构的显示得到改善，肺部结构细节相似。使用带有特殊格栅的ITC-VHC系统时，外周肺部的细节显示明显优于不使用格栅时。然而，使用格栅时辐射剂量会增加约三到四倍。
我们的试验表明，由于能更好地显示细节，ITC-VHC格栅系统推荐用于常规临床使用，但必须意识到患者的辐射剂量会增加。
