In the analysis, the image quality, easiness to use, and cost-performance of the multi-format camera and the laser imager which are used for recording CT, MR and DSA images were compared. The dynamic range of CRT for the multi-format camera is not sufficient to reproduce the digital image and distortion of the image of it was frequently observed. However, high quality CRT provided an image of higher resolution than that of the laser imager. When the laser imager was connected to the diagnostic imaging system, the digital-analog image transfer caused the degradation of the image quality compared with the digital-digital image transfer. However, the laser imager showed some merits in image storage, image processing and image control. In addition, the magnification of the image caused the degradation of the image quality for the multi-format camera. However, the influence of the image size on the image quality was small as regards the laser imager. In conclusion, the laser imager was superior to the multi-format camera regarding CT and MR image while both recording device systems were equal in DSA images.
