Image Processing Requirements and Distributed Networks in a Digital Imaging Environment
- 1982
-
Ingår i: Proceedings of Annual Symposium on Computer Application in Medical Care (SCAMC ’82). - : IEEE. ; , s. 923-
-
Konferensbidrag (refereegranskat)abstract
- This paper will discuss a unified digital image distribution and processing system linking various digital image sources through a broadband local area network and a comnon image format. Ultimately, the system allows for viewing and processing of all images produced within the complex, and for viewing stations at any number of convenient locations. The physical handling of storage media at image sources, can be totally eliminated. Complete archiving, file maintenance and large scale processing capabilities are provided by a central file server. This paper presents a concrete proposal for an initial system which has a central archiving facility for permanently storing and selectively viewing computed tomography (CT), nuclear medicine (NM) and ultrasound (US) images. The system proposed can then be slowly expanded to include all the digital images produced by the radiology the department, and ultimately to include all the images by digitizing those produced in an analog fashion.

Mätmetoder för att bestämma modulationsöverförningsfunktionen för radiologiska system
- 1981
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Detta kompendium är avsett att ge en kort beskrivning av några olika metoder att bestämma modulationsöverföringsfunktionen, MTF, för ett radiologiskt system eller del av radiologiskt system. Vidare försöker kompendiet beskriva en del av de praktiska svårigheter som är förknippade med att mäta MTF. Den matematiska bakgrunden finns kortfattat redovisad i appendix.

Resolution, unsharpness and MTF
- 1980
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Resolution: The ability of an imaging system to register separate images of two closelysituated objects. Unsharpness: The ability of an imaging system to reproduce a sharp edge. The resolving power of the radiological image depends on the combined effect of different kinds of unsharpness (see below), the number of X-ray photons to produce the image and the contrast. In other words, the resolving power depends on the MTF of the imaging system, the quantum noise and the contrast. The resolution of the imaging system is usually measured using a test object with alternating transparent and absorbing lines. The resolution power is then usually given in line pairs per millimeter (lp/mm), i.e., gives the number of "tops" and "valleys" that can be detected per millimeter.

A distribution system for digital images from diverse image sources : Incorporating a local area network in an imaging environment

Tidskriftsartikel (refereegranskat)abstract
- This paper proposes a unified image-processing and viewing system as a viewing station and initially as the central file server in a unified digital image distribution and processing network, linking various digital image sources through a high speed data link and a common image format. The network allows for viewing and processing of all images produced within the complex and for locating viewing stations in any number of convenient areas. The system proposed can be slowly expanded to include all the digital images produced within the department of institution.
