![]() ![]() The x-ray light valve: a potentially low-cost, digital radiographic imaging system-concept and implementation considerations. However, even with this limitation the XLV system is able to meet or exceed the resolution requirements for chest radiography. The Modulation Transfer Function was measured and the limiting factor was seen to be the optical scanner. A prototype XLV was made and a typical office scanner was used for image digitization. Due to the close electrostatic coupling in the XLV, it can be expected that the spatial resolution of this system will also be very high. Both a-Se and LC cells have both been shown separately to have inherently very high spatial resolution. Here we investigate the spatial resolution possible with XLV systems. The XLV concept combines three well-established and hence lowcost technologies: an amorphous selenium (a-Se) layer to convert x-rays to image charge, a liquid crystal (LC) cell as an analog display, and an optical scanner for image digitization. The XLV has the potential to achieve the immediate readout in an integrated system with image quality comparable to AMFPIs. We have identified a new approach - the X-ray Light Valve (XLV). These approaches suffer from either high cost or high mechanical complexity and do not have the image quality of AMFPIs. Different approaches have been considered to make lower cost, integrated x-ray imaging devices for digital radiography, including: scanned projection x-ray, an integrated approach based on computed radiography technology and optically demagnified x-ray screen/CCD systems. Thus there is a need for a low cost digital imaging system for general applications in radiology. However, these active matrix flat panel imagers (AMFPIs) are extraordinarily expensive compared to the systems they are replacing. ![]() ![]() In recent years, new x-ray radiographic systems based on large area flat panel technology have revolutionized our capability to produce digital x-ray radiographic images. ![]() We take pride in our 100% rating and hope to keep it that way.PICTURES:We take our own pictures.What you see in the pictures is what you will be receiving.DESCRIPTIONS:We do our best to accurately describe each item, the condition and anything else that might pertain.If you have any questions please contact us and we will do our best to answer.PAYMENT:We only accept PayPalIf payment is not made within 3 days we will open an unpaid item case with Ebay.FREIGHT:We offer FLAT RATE SHIPPING on this item.We ship out the most economical method possible.We use USPS, Federal Express or UPS of our choose.We take extra care in packaging each item.We normally ship within 3 days of PaymentLocal pickups - Please Contact us to arrange.International Shipments - Please use the EBAY Global shipping program.RETURNS:We offer a 30 day return policy on all our items and BUYER pays for the return shipping.If the item was damaged via shipping, we will file a claim with the shipping company.If the item does not meet the item description or is defective, we will pay for the return shipping.ISSUES:We strongly urge buyers to contact us first if a problem arises.We will do our best to ensure that everything goes smoothly, but mistakes can happen.The x-ray light valve: a low-cost, digital radiographic imaging system-spatial resolution Our items comes from a few different sources but we personally clean, test, list, package and ship each item ourselves.
