Digital Processing for Modifying and Rearranging Rectilinear and Section Scan Data under Direct Observation

Abstract

Our digital processor for scan data is an on-site instrument that is intermediate in complexity between conventional optical processing devices and large digital computers. It is designed to provide for a wide and flexible range of secondary data operations, direct picture display on a CRT screen, and full operator control of both processing and display operations at the time of viewing. The instrument does not require the user to learn complicated programing schemes. The operator is expected to be a physician who will control the parameters of interest by punching preset buttons on a keyboard while observing changes displayed on a CRT screen. The system functions primarily as an investigative tool for studying perception of scan information and ways of making this information more meaningful. Data operations include data bounding, spatial averaging, iso-count line generation, image addition and subtraction, and several forms of quantitative read-out for analysis of regional data. The instrument is intended to serve as a central processor and reader for data from several units. Investigations with this processor have served as a source of information leading to the design of more simple processing devices suitable for wider acceptance. For example, the Mark III rectilinear and transverse section  More>>

Investigations with this processor have served as a source of information leading to the design of more simple processing devices suitable for wider acceptance. For example, the Mark III rectilinear and transverse section brain scanner that has evolved from this project is expected to be a practical improvement of the brain study method. This instrument is designed especially for rapid brain scanning using {sup 99m}Tc pertechnetate. It has a self-contained computer, integrated digital circuits for compactness and economy, and provision for transverse section scanning. The advantages of this system are that it provides a more thorough study using both transverse section and rectilinear modes, rapid performance, precise orientation of section and rectilinear views to the patient position, efficient transfer of information between physician and machine during studies, and economy of design which should encourage wide application.
