    Intuitive Operator Interface and Expert Mode
    Renaissance has two distinct interface modules to manage Supervisory/Expert functions from those associated with routine measurement operations.

    The Supervisor module is used for the initial system configuration, setting Operator permissions, and more detailed spectrum analysis evaluations. This module can also be used for customized measurement processes using automation Jobs similar to ORTEC’s flagship GammaVision application with the ability to analyze High and Low resolution spectra.

    The Operator module provides a simple and intuitive interface for all routine operations including personnel measurements and instrument checks with minimal experience or training.

    Spectrum Analysis and Reporting
    Renaissance provides accurate identification and quantification of radioactive material using high and low resolution gamma spectroscopy in personnel monitoring systems. These systems can be supplied in a variety of physical and operational configurations with different combinations of High Purity Germanium and Sodium Iodide detectors that can be analyzed as a group or individually.

    Analysis reports are highly customizable with Crystal Reports using results stored in a Microsoft Access database, and these reports are easily accessed from the Operator module.

    When more detailed spectrum analysis evaluation is warranted, the Supervisor module can be used to graphically display peak fits and adjust analysis settings as necessary to optimize results.

    Quality Assurance

    Periodic instrument performance checks are necessary to ensure that the system is operating properly when samples are analyzed. These checks may be required by regulations, standards, or other governing bodies that may audit the results. The minimum performance measures should include validation of the system calibration parameters, limits that define acceptance and a warning when these limits are exceeded. Control charts for trending is also desirable and formally required for some applications.

    Instrument Control
    The interface between instrumentation and software is provided through the ORTEC CONNECTIONS framework which supports up to 250 detectors across a local network. This application layer encompasses all of the hardware drivers and communication protocols that are necessary for software applications to control the MCB (Multi-Channel Buffer) instruments. Instrumentation controls are accessed through MCB Property pages that are integrated with Renaissance and other standard ORTEC applications.

    Windows 8.1 and 7 64-bit hardware compatibility is available for all ORTEC instruments that use USB and TCP/IP connectivity. These instruments, as well as other legacy hardware, are also supported with Windows 71 and XP 32-bit operating systems. Instruments that are dependent on a host computer, such as plug-cards or USB devices, can be shared on a network through the MCB Servers running on each computer. This process allows Windows 8.1/7 64-bit computers to operate instruments that are not 64-bit compatible through their 32-bit host.

    g List Mode Data Acquisition2
    g High Voltage Bias Control
    g Course and Fine Gain Adjustment

    Further details for hardware functions are provided in the relevant product literature.

    Motor Control
    Renaissance enables automated scanning systems through standard Galil Motor Controllers. These scanning systems are calibrated for the start (HOME) position, scan length, scan speed, return speed, and maintenance positions to optimize system operation and ensure that measurements are consistent with the configuration implemented with system calibration.

    Scanning systems are typically configured at the factory for Turn-Key operation. Adjustments to the position and speed calibrations are then easily implemented at the customer site with the comprehensive Motor Control Setup program included with Renaissance.

    1. Instruments using the IPX/SPX protocol require Windows XP. This may be accomplished on a Windows 7 computer using the XP Mode Virtual Machine. Instruments that have a Dual-Port Memory option can take advantage of the DPM-USB to communicate over a USB connection in the Windows 8.1, 7 or XP environments.
    2. List Mode Data Acquisition is available for specific instrumentation, such as the DSPec-50/502, DSPec-Pro, and others.
