System Description6H4866-02 15Section 2: System DescriptionIntroductionThroughout this manual the Kodak Point-of-Care CR 120/140 Systems will be referred to as thePoint-of-Care CR 120/140.The Point-of-Care CR 120/140 is designed for the reading of phosphor x-ray screens (CR) by medical professionals.The system consists of the Point-of-Care CR 120/140 unit and the software package that includes:• The Kodak QC software that operates the unit.• An image viewing and archiving software package that supports the DICOM 3.1 standard and was approved byCarestream Health.• The system features 8 x 10 in.; 10 x 12 in.; 14 x17 in.; 9.5 x 9.5 in. digital image reading and viewing archive.Operational PrinciplesThe Point-of-Care CR 120/140 is a digital imaging system for image acquisition and processing of static projectionradiography that uses a phosphor screen with energy storage capability as an x-ray image receptor.After exposure, a laser beam, which stimulates luminescence proportional to the local x-ray exposure, reads thescreen. The luminescence signal is digitized. The data is then subjected to digital image processing.The Point-of-Care CR 120/140 enables the user to read a screen quickly, and erase it to be ready for the next scan.The unit is compact and easy to use.Using the Point-of-Care CR 120/140 enables medical professionals to “go digital” without changing their workpractices or x-ray equipment.System OverviewSystem ComponentsThe Point-of-Care CR 120/140 consists of 17 major assemblies as well as sensors, which may be replaced in thefield:USB Board Erase Lamps AssemblyMotion Board Erase Lamps Inverter AssemblySensor Board Sensors:Photo Multiplier Assembly W0 SensorOptic Head Assembly Z0 SensorRoller Motor Assembly Rollers SensorLinear Slide Assembly Screen Size SensorsLoader Stepper Motor Assembly R-Limit (Home) SensorKey Assembly and Tray Assembly L-Limit SensorPower Supply Assembly Loader Back SensorCassette Lock Cassette PresentAuto-loop
