GAMMA-11

This document is the Operator's Guide for the GAMMA-11 system, dated January 1978. GAMMA-11 is a software application designed for the acquisition and analysis of gamma-camera data in nuclear medicine departments.

The manual provides comprehensive instructions for operating the system, which runs under the RT-11 operating system. Key sections include:

• System Overview: An introduction to study types (Static, Dynamic, List, Gate-Synchronized, Gated-List, Flood, and Predefined) and hardware requirements.
• Software Environment: Explanation of RT-11 foreground/background (F/B) operation and how GAMMA-11 utilizes these resources.
• Starting Procedures: Step-by-step instructions for loading GAMMA-11 for both single-job and foreground/background configurations, including command usage and keyboard/control character protocols.
• Data Acquisition: Procedures for setting up and acquiring patient studies, managing disk space, and using the "Predefined Study" feature to standardize workflows.
• Data Analysis: A detailed reference for commands used to analyze data, including image enhancement, region of interest (ROI) selection, slicing, frame algebra, and macro usage for automation.
• Color Display: Specialized commands for managing color tables, interpolated displays, dual-screen overlays, and dynamic playback.
• Utilities: Procedures for file deletion and study transfers between storage media (e.g., disks and magnetic tapes).
• Flood Correction: Methods for correcting gamma camera field non-uniformities.

The guide concludes with appendices covering startup procedures for specific hardware (PDP-11/40), a summary of commands in alphabetical order, and a glossary of terms.
