Data X-ray Image Intensifier HIDEQ 23-3 ISP
State-of-the-art Image Intensifier Technology HIDEQ 23-Mu Features and benefits HDQE cesium iodide input phosphor screen of very fine structure deposited on a highly transparent aluminium input window provides low quantum noise and excellent resolution and makes a significant reduction in X-ray dose possible Metal enamel technology providing high precision components with excellent X-ray transparency and negligible X-ray scatter Electron optical zooming for improved detail visibility and increased resolution properties HR output phosphor combined with a high contrast output window featuring an anti-glare screen and scattered light trap ensures high luminous efficiency and unsurpassed overall image definition with high contrast and high resolution HIDEQ 23-Min Automatic dynamic ion-getter pump to ensure the highest vacuum throughout tube life Mu-metal encapsulated tube for very low geometric distortion 9 /23 cm, three fields High DQE, resolution, contrast and conversion factor Low distortion Good luminance distribution HIDEQ 23-Lateral The products HIDEQ 23-Min and HIDEQ 23-Lateral bear a CE marking in accordance with the provisions of the 93/42/EEC directive dated June 14, 1993 concerning medical products, limited to the system component. The product HIDEQ 23-Mu does not bear a CE marking. Technology Image intensifiers from Siemens are renowned for their brilliant contrast and low geometric distortion. These are the results of continuous development in our product line. Blemish- and artifact-free Narrow process tolerances ensure constant electron-optical data, minimal disturbing blemishes and artifacts, resulting in excellent image quality. 2
