Initial assessment of the DSI unit proved the ergonomic advantages of the system compared with a conventional fluoroscopic/fluorographic system. Also, a decrease in radiation dose levels proved encouraging. Savings in respect of hard copy expenditure and higher patient throughout area which the DSI technique can exploit. However, spatial resolution is still not equal to that of conventional film/screen imaging, but the 1024 matrix option and the facility for post-processing of the images in terms of contrast, brightness and edge enhancement have produced diagnostically acceptable images for all examinations undertaken (see figures 4 and 5).
对数字减影血管造影（DSI）设备的初步评估证明，与传统的荧光透视/荧光摄影系统相比，该系统具有人体工程学优势。此外，辐射剂量水平的降低令人鼓舞。在硬拷贝支出方面有所节省，并且DSI技术可以利用更高的患者检查区域通量。然而，空间分辨率仍不及传统的胶片/屏幕成像，但1024矩阵选项以及在对比度、亮度和边缘增强方面对图像进行后处理的功能，已为所有进行的检查生成了诊断上可接受的图像（见图4和图5）。
