System Overview

Typical Room Layout for the DR 7500 System

See the Kodak DirectView DR 7500 Safety and Regulatory Guide for Safety and Regulatory information for the DR 7500 System.

Digital Radiography Digital radiography captures and converts X-ray energy into digital electrical signals. • The captured signals (14-bit image data) are immediately transmitted into the Array Controller. The 14-bit linear data is converted into 12-bit log data. • An Image Processing Library (IPL), associated with the radiographic procedure and position, is used to create a look-up table (LUT) for the image. • The LUT is applied to the 12-bit log data to optimize the image data prior to viewing on the Operator Console. If the user accepts the image, the LUT and the image data are sent to the selected output devices. CAUTION:

Follow all safety labels on the equipment.

Indication for Use

1-2

The Kodak DirectView DR System is a permanently installed diagnostic system intended to generate and control X-rays for examination of various anatomical regions. The Operator Console for the DR System is used whenever generation and transmission of radiographic images and associated patient data is desired to take place from the DR System, to any output device, such as hard copy, soft copy or archive devices.

X-ray Generator

The DR 7500 System may be set at any level up to the maximum settings for a given kV and mA. The maximum power (kV* mA) must never exceed 80 KW. Exposures near the 80 KW power level may also be limited to less than the maximum exposure times. • 80 KW high frequency One Tube Generator • Operator control through the Operator Console

Timing and Distribution Unit (TDU)

The TDU is the focal point for both system communications and power distribution. The TDU is divided into 2 sections: • The upper section houses the System Control Unit (SCU) board. The SCU handles all of the timing and communications between the major assemblies of the DR System. The SCU provides the interface for communications to the X-ray Generator via the Generator Personality Module, also housed in the SCU section of the TDU. • The lower section houses the Power Control Unit (PCU). The PCU area provides the connection for the incoming 480 V AC Mains power provided by the facility. The PCU transforms and distributes power to the rest of the system. The PCU powers a UPS (housed in the PCU section of the TDU), which in turn provides 240 V AC to the Operator Console. In the event of power loss, the UPS provides power to the Operator Console and to the SCU. The PCU allows all of the power requirements of the DR System to be satisfied by the single connection of the 480 V AC Mains power. The UPS Power switch controls power to the Operator Console. The TDU controls power to the Wall Stand, Overhead Tube Crane, and the Table. To turn off the system, see “Turning off the System Completely (All AC Power Off)” on page 1-17.
