Description

Abacos-2000 brings the power and flexibility of the world�'s most widely used Whole Body Counting software �- the ABACOS family �- to systems based upon the cost-effective Genie 2000 platform. The result of combining the proven capabilities of VMSbased ABACOS with the unique benefits offered by the Windows NT�®-based Genie 2000 is a flexible yet easy-to-use menu-driven program capable of meeting all of your Whole Body Counting needs.

ROUTINE COUNTS - JUST LOG ON AND GO

Routine counting operations provided by ABACOS allow the user to run a simple command to perform an entire count sequence, complete with data acquisition, analysis, and reporting.

Routine Operations

Routine operations are easy to use tasks with all of the parameters preset so the technician only has to choose a Counter (e.g. FASTSCAN) and Count Type (e.g. Individual - 60 sec), start the count, and then enter the subject ID.

Since all of the tasks and parameters needed to start, stop, transfer data, perform analysis, and generate reports have been set up as defaults previously, Abacos-2000 takes it from there.

Relational Database for Subject Demographics

Default personnel information is maintained in a relational database. Subjects are identified by name or ID number. Data entry screens with pre-defined personnel information from the database are automatically displayed during Routine Counts. The predefined information may be accepted for storage with the count data, or may be modified for storage with the count file. Simple fill-in-the-blank dialogs prompt the operator for the needed information.

This input process runs in parallel with the Routine Count for maximum system throughput.

Analysis and Reporting

At the completion of the Routine Count the results may be displayed on the CRT, or a hard copy may be generated.

The Analysis Sequence File defined for the Routine Count Type determines which analyses are performed and which reports are generated.

Relational Database for Count Results

Routine Count results are sent to the Logbook Database. The results are then readily available for screening, batch analysis and reporting, and electronic review using the Manual and Utility functions of Abacos-2000.

In Vivo Counter Configurations

Abacos-2000 has the flexibility to handle a wide variety of in vivo counting systems, including static and scanning counters and single or multiple (summed) Germanium or NaI(Tl) detector based systems. Multiple systems of varying types and detector configurations are supported by the same software.

The secret to this flexibility is the use of user-definable Counters, Arrangements, and Groups to handle the interface between the Abacos-2000 acquisition and analysis logic and the physical characteristics of the various types of systems.

Counters

Abacos-2000 provides simple fill-in-the-blank dialogs to establish the hardware controlled by a Counter. Each Counter is given a unique name within Abacos-2000. When that name is used to specify a Counter, the control and acquisition logic is automatically tailored to the system�'s detectors and electronics.

Arrangements

Arrangements provide a definition of the count parameters to be used. Each Arrangement is given a name within Abacos-2000. All control and positioning parameters are defined within an Arrangement, and handled automatically during a count. Each Counter may have more than one commonly used Arrangement.

Count Types (e.g. Individual - 60 sec) are also defined under each Arrangement. Multiple Count Types may be defined for each Arrangement, with each Count Type having its own Detector Group and Live Time associated with it.

Detector Groups

Detector Groups are used to define the spectral data analysis parameters. A Group may be defined to contain one or more Detectors. Detector summing is defined at the Group level, as is the default analysis and reporting sequence. Calibrations are defined either for single Detectors or for Groups.

Analysis and Reporting Sequences

Analysis Sequence Files (ASF) define the analysis and report sequences and parameters which are used as the defaults with a particular Detector Group. A menu driven editor makes it easy to create new ASF files or modify existing ones. A set of standard whole body counting ASF files is provided with Abacos-2000.

LOGBOOK DATABASE - COUNT RESULTS STORAGE

All results are automatically stored in Abacos-2000�'s Logbook Database. These results can then be retrieved, reviewed, edited, and reported using a variety of selection criteria.

Select Entries by Count Type, Subject Name, ID, and/or Date

A flexible Count Selection Filter makes retrieving specific results of interest a simple �"point and click�" job. Drop down selection lists and editable criteria limits give you the flexibility to select entries from the Logbook based upon:

1. Specific count types of interest (e.g. Subject Counts, Calibrations, Background Checks, etc.).
2. One (or a range of) specific Name(s) or ID Number(s).
3. One (or a range of) specific Date(s)/Time(s).

Additionally, you can restrict the selection to only those entries that have not yet been through the Data Review process, a feature that is especially useful when using the AutoScan Option for unattended operation.

Database Edit/Report

Once the selection of Logbook entries has been made, editing and report generation dialogs provide the flexibility to tailor the results to site-specific needs. Four predefined report types are offered, with both hard copy and disk file outputs. One of the reports is an ASCII output file compatible with import file formats for CINDY (Computer-based INternal DosimetrY System). Simple SQL queries can be used to generate any custom reports required by the facility.

Batch Functions

The Logbook Database makes it possible to have batch functions which make the job of data reporting and reviewing easier. Using the Logbook selection filters, the manager can batch reanalyze, report, and electronically review groups of files.

TASK BASED SECURITY ON AN INDIVIDUAL BASIS

Abacos-2000 has a unique security structure that both improves the integrity of the system and at the same time makes the software easier to use.

User Name and Password for Basic Access

A traditional User Name/Password combination is used to gain access to Abacos-2000 functions, with the System Manager having complete control over the authorization list. Once a user is logged on, his or her ID is stored as part of the data file, improving traceability and accountability for all counts.

Selective Security on a Functional Basis

Just because a user is logged on to the system doesn�'t mean that full access is available. An overall security level assigned on an individual basis acts as a �"filter�" to limit the user�'s access in general terms. In addition, specific tasks can be selectively allowed or disallowed for that individual, further tailoring the user�'s access to the specific requirements of his or her job.

Security selection screens.

Better Security and Easier to Use

The net result is both better system security and improved ease of use, for Abacos-2000 automatically tailors all of its menus to show only those choices for which the current user has been authorized access. With no �"grayed out�" menu choices to confuse the issue or �"Access Denied�" warnings to worry about, the system�'s operator interface is always optimized to the needs of the user who is currently logged on.

WITH THE POWER OF GENIE 2000 BEHIND THE SCENES

Since Abacos-2000 is built upon the powerful Genie 2000 platform, there are a host of additional powerful tools available as part of the Abacos-2000 package. Additional Genie 2000 tools which are not part of the standard Abacos-2000 package are also available.

Certificate Files for Simplified Energy and Efficiency Calibration

Certificate files containing complete data on the calibration sources greatly simplify the calibration process. Since certificate files eliminate complex manual data entry when a calibration is performed, they improve system integrity by eliminating a potential source for error.

Calibration Plots and Reports for Instant Verification

When a calibration is performed the curves are displayed both numerically and graphically, allowing for quick verification of the results. Data for the calibration can come from a single mixed nuclide acquisition or from several different calibration acquisitions and then combined to yield a single optimized curve.

Nuclide Library Editor for Easier Library Customization

A simple fill-the-blank library editor makes it easy to have multiple radionuclide libraries, each custom-tailored to a specific location, unique environmental setting, or a particular type of analysis.

QA System for Tracking System Performance Over Time

The Genie 2000 Quality Assurance System is used by Abacos-2000 to track the performance of the system over time. Variations in background levels, the impact of ambient temperature changes, and the effect of aging of the system�'s components are among the many parameters that can be monitored. Any information accessible to the computer may be stored and trended. All information goes into a QA database, and a flexible reporting mechanism is provided for trend analysis.

UNATTENDED OPERATION - AUTOMATED FASTSCAN OPTION

Abacos-2000 is also completely compatible with the Model 2252 AutoScan Option, providing the flexibility of automatic self-service operation with any Fastscan Whole Body Counting System. Using a barcode reader and keypad for input, the AutoScan makes WBC as easy as a simple gross counting, with the added benefits of:

• The low MDAs of a true spectrographic WBC
• The full legal and regulatory protection of a gamma spectrographic record

WINDOWS NT FOR SYSTEM CONTROL AND NETWORK ADMINISTRATION

All Genie 2000 software runs under the multi-tasking Windows NT Operating System. With its sophisticated networking capabilities you are assured that you can expand your system to meet most any level of need. Multiple whole body counting systems, traditional sample assays stations, dedicated file and print servers, and supervisory control and monitoring stations - both local and remote - can all be networked together into an integrated Health Physics Laboratory  System.
