General Information
Section 2: General Information Overview of the DRX-Ascend System This manual provides information for the operation of the DRX-Ascend System, which is a communications interface between the CARESTREAM DRX-1 Digital Radiographic Imaging Workstation and Quantum Medical Imaging HF Series X-ray Generator.
Note The user should read this manual in its entirety prior to using this equipment. It should be kept in a location near the equipment and be readily accessible to those who operate it. When the QG-DIG-DRX Integration System is installed, all user interaction with the HF Series X-ray Generator is accomplished via the Workstation’s touchscreen, thereby eliminating the need for a separate Operator Control Panel for the generator. In addition, Quantum’s optional TechVision Control Panel can be installed and synchronized with the DRX-1 Workstation to optimize operator efficiency.
Note TechVision is a functional operator interface control panel providing access to generator controls and visual presentation of the exposures taken in the current study. TechVision is designed for installation in the patient area, and has full programming/editing capability, but it cannot activate an exposure. Once the patient is registered in the DRX environment and the appropriate body part examination procedure is selected, the generator control parameters are uploaded prior to performing the exposure. DRX-Ascend System technology is available for DRX-1 Series digital detectors, in applications where a DRX-Ascend System, including an HF Series X-ray Generator, is installed. The QG-DIG-DRX System software resides on the DRX-1 Workstation computer hard disk, and is automatically loaded whenever the workstation computer is powered up. Combining the image acquisition capacity of the DRX-1 digital detectors with QG-DIG-DRX System software controlling an HF Series Generator, worklists compiled from stored patient profiles, or those manually entered, are displayed for immediate disposition in the DRX operating environment. Operation of the DRX-Ascend System software is accomplished through a touch-sensitive operator control panel screen integrated with the DRX-1 Workstation screen. Once the DRX Software is installed and a Service Technician has completed the system and generator setup, it is not necessary for the operator to access and adjust the Service Options.

Electrical power to the generator is controlled via a Power/Expose Control Box, which houses an ON/STBY rocker switch and indicator LED. The Power/Expose Control Box also serves as an interface for the two-stage Expose switch, which enables the operator to trigger the exposure (“one-button” exposure, or “prep” exposure). The Expose Switch is hard-wired to the Power/Expose Control Box, with an expansion cable which allows the operator to move about the area.

General Information
Key Features of the QG-DIG-DRX Integration System It is imperative that all safety procedures described in this manual be strictly adhered to in order to ensure the safety of both patient and user. The key features of the DRX-Ascend System are as follows: • Elimination of separate control units for each operating environment. • Transparent upload and translation of selected Patient Procedure List and Patient Data from the DRX environment to the generator. • Integrated touchscreen, presenting DRX Radiographic Imaging screens and menus, and adjacent to that is Quantum’s Generator Control Panel, with several adjustments. – exposure settings – receptor selection – manual or AEC mode of operation – Generator status – Tube Heat and Post Time/mAs callouts • Power/Expose box with generator ON/STBY switch, and two-stage Expose Switch, including expansion cable. • Three Standard Receptor groups (Wall, Table, and None), with the capacity to define multiple “named” receptors and calibrations for Wall and Table (e.g., Wireless1, Wireless2, etc). • The "None" Workspace enables exposures without a digital receptor present, such as when seasoning the X-ray tube, or for calibrating the generator (service function only). • Universal AEC option for expanded AEC capability • Multi-language display capability
Intended Use The DRX-Ascend System provides diagnostic quality images to aid the physician with diagnosis. It can be used to perform radiographic exposures of the skeleton (including skull, spinal column, and extremities), chest, abdomen, and other body parts. This System is not indicated for use in mammography.
Main Components of the System Successful integration of the QG-DIG-DRX System requires the following hardware components, provided with the DRX and Quantum Medical Imaging Radiographic Systems. 1. DRX-1 Workstation touchscreen display monitor-Provides visual display of various data modules, and supports the Quantum Generator Control Panel (a touchscreen occupying the area to the right of the DRX operating screen). 2. Workstation computer-Provides operational capability for DRX-1 Workstation, and supports Ethernet communications between the workstation (running Quantum’s QG-DIG-DRX Integration Software) and the generator. 3. Power/Expose control box-Provides control of the generator’s main power, and interfaces the two-stage Expose Switch to the generator. 4. Ethernet switch to interface the generator to the workstation and peripherals.
Note The Power/Expose control box must be securely mounted in a location where the operator can hear the audible alarm output during exposure cycles, and where the operator can see the exposure icons displayed on the workstation screen.

System Operation
Section 3: System Operation Overview This chapter provides the information necessary to operate DRX-Ascend System Software to obtain images with Quantum Medical Imaging equipment and DRX-1 Digital Radiography Systems. The following operating procedures are outlined and described in detail: • Distinctions between the DRX-1 operating environment and the Quantum QG-DIG-DRX operating environment as encountered on the workstation touchscreen • QG-DIG-DRX Integration System Software control of the generator when synchronized with the DRX-1 Workstation • Operating instructions
WARNING This equipment must be operated with reasonable care. The manufacturer’s equipment recommendations described in this manual must be observed.
QG-DIG-DRX Integration Screen QG-DIG-DRX Software initializes automatically when the DRX-1 Workstation is powered up. The workstation touchscreen presents a single (visually integrated) screen which includes the DRX-1 and Quantum operating environments. The screen for both operating environments is touch-sensitive. The operator can utilize the preprogrammed examination profiles and access the generator controls at any time via the Generator Control Panel, which resides on the right side of the screen. This eliminates the need for a separate Generator Operator Control Panel, and manual generator setting input for examinations associated with a predetermined patient profile. Because the Integration Software operates in sync with the DRX-1 Digital Radiographic System, the operator is provided with not only the convenience of handling all preparatory activities, such as those designed into the DRX-1 system regarding patient information and examination profiles, but also the convenience of adjusting the generator power settings while operating from the workstation area.
