Abstract

For today's and tomorrow's high developed imaging systems CT, MR, DSA, NM, US, DR we need equally highly developed recording equipment to produce high-grade quality "hard copies" at the end of the image transfer chain. For this reason we present a new laser image recording technique with Laser Imager and its operational principle. The Video Imagers (multiformat cameras) used until now are no longer up to date due to their disadvantages for imaging documentation of high-resolution imaging systems. The direct exposure of a single-emulsion-silver-halogenide transparency film with laser light, produces low-noise distortion-free and homogeneous documentation images. The size of the matrix of 4000 x 5000 pixel and 12 bit image depth guarantees the use of the Laser Imager also for future imaging systems with a higher size matrix than is now usual. The modulated accessories such as Multi-Modality Unit (MMU) and Multi-Console Laser Switch (MCLS) guarantees a flexible and more economic use of the Laser Imager.

摘要

对于当今和未来高度发达的成像系统,如CT、MR、DSA、NM、US、DR,我们同样需要高度发达的记录设备,以便在图像传输链的末端生成高质量的“硬拷贝”。因此,我们介绍一种采用激光成像仪的新型激光图像记录技术及其工作原理。到目前为止所使用的视频成像仪(多格式相机),由于其在高分辨率成像系统的成像记录方面存在缺点,已不再适用。用激光直接曝光单乳剂卤化银透明胶片,可产生低噪声、无失真且均匀的记录图像。4000×5000像素的矩阵尺寸和12位图像深度,确保了激光成像仪也可用于未来具有比目前常见尺寸更大矩阵的成像系统。诸如多模态单元(MMU)和多控制台激光开关(MCLS)等调制配件,保证了激光成像仪的灵活且更经济的使用。
