Display Of Radiological Information Software [DORIS]

The DORIS Software System provides real-time data reporting and control through a user-friendly graphics display with an easy to use operator interface system. Data is collected, analyzed, displayed and recorded in real-time while posting alarms for operator notification. The operators will be able to display and perform the following at either the RDM series display unit or DORIS hardware platform in real time:

(a)	Current readout of background or gaseous activity
(b)	Detector information (type, SCA set-points, etc.)
(c)	High/Alert/Fail alarm status
(d)	Detector status (fail, normal, etc)
(e)	Keypad status
(f)	Trend information
(g)	Graphic representation of trending data

DORIS functions include:

	Collecting, converting, storing, integrating, and analyzing data from all monitors.
	Detecting, annunciating, and storing alarm conditions.
	Providing current, as well as historical, displays of any channels on operator request.
	Generating system and graphic displays.
	Providing on-line data base and display generation and modification capability.
	Providing on-line diagnostic displays.

Some Examples of DORIS Screens

Display II (Real Time Single Channel Trace)

Selecting a channel (by double clicking the appropriate display box in Display I), will display the Real Time Single Channel Trace. The Real Time Single Channel Trace display provides the user with three options for data presentation for the selected channel. The first (and default) view of the data is the Instantaneous Data view in a columnar format. By selecting this tab, the user can view the real time data for the channel as it is received from the monitor. Data is displayed in table type format showing various metrics such as date/time stamp, value, validity flag, etc. The second view presents the data in a graphical format. As with most DORIS functions, the user has extensive control over details of the display. For example, the user selects the graph type (i.e. line, bar, chart, etc.). Additionally, the graph area can be panned (left, right, up or down) and zoomed (in/out). Other controls for graph color, tick line indication, point display style, line display style, etc., are available on the Graph Configuration tab. One minute average data is shown in the third view of the data. This data is displayed in table type format showing various metrics such as date/time stamp, average value, maximum value, minimum value, validity flag, etc.

Display IV (Historical Multi Channel Trace)

The Historical Multi Channel Trace display is similar to the Historical Single Channel Trace display. The display again provides tabular and graphical views of the data for a user selected period and averaging interval. For this Display IV, the difference from Display III lies in the Multi Channel versus Single Channel functionality. This Historical Multi Channel Trace display provides the user the ability to view data from a group of channels simultaneously. The data groups (or templates as they are referred to in DORIS ) are previously defined via a Template Library. The number of templates maintained by DORIS as well as the number of channels contained within each template or group is a function of hardware and aesthetic limitations.

DORIS Tools Menu and Functions

In addition to the more commonly used displays as described above, DORIS provides a number of tools and library functions to further maintain and configure DORIS for optimal use. A partial list of these tools and functions follows:

	User Authorization and Password Maintenance
	Site Sensor Library
	Site RAM Library
	Template Library
	Period Library
	Color Code Library
	Event Library
	Measurement Units Library

PET Libraries

The DORIS PET library data is easily accessible and includes: Isotope Library, PET Target Library, PET Tracer Library, Release Point Library, Release Point Sensor Library, Release Point Limit Library, Sensor Isotope Calibration Library.

PET Alarm Surveillance Function

The Alarm Surveillance function provides the ability to associate the occurrence of the various alarm events with the corresponding rate information stored in the DORIS database DORIS can be used to monitor the entire cyclotron facility including the cyclotron vault and control room, the hot cells and hot cell room, target preparation and recovery rooms, the radiochemistry laboratory and radio-pharmacy, the waste water storage room, all corridors surrounding these areas and the door-ways that exit from the cyclotron complex. In addition, all exhaust stacks serving the cyclotron facility can be continuously monitored. Each computer & monitor is equipped with an 8 hour battery back-up in the event of a power failure. All of the Digital Area Rate-meters, that feed information from their associated detectors back to the computers, can be wired in such a manner that the loss of any single Rate-meter will not interrupt the flow of data from the remainder of the installation. These signals, available from the computers or the area rate-meter, can be used to activate or de-activate various fan motors, dampers, door interlocks or any other electrically powered device in the facility.
