For new applications of computer graphics to be developed and used, the graphics terminal must meet the requirements of users and applications. Because many of the users will be nonprogrammers and the interactions will involve pictures, the applications are significantly different from those currently supported by batch computing or alphanumeric terminals. Studies of users, applications, and implementations of interactive computer graphics systems have resulted in thirty specific requirements for the display screen, the associated hardware for input, output, processing and storage, the interaction rates, the terminal packaging, and the support of the applications programmer. Comparison of existing graphics terminal alternatives in terms of the requirements indicates that eighteen of the thirty requirements are provided inadequately. Comparison of the relative importance of the requirements for different classes of applications indicates that color, image mixing, hard copy output, portability, upward compatibility, and reduced reflection, glare, and noise would be the most useful terminal improvements for developing new applications of computer graphics.","PeriodicalId":160433,"journal":{"name":"Proceedings of the 3rd annual conference on Computer graphics and interactive techniques","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128181933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes a computerized method for obtaining images of the dynamic spatial distribution of x-ray attenuation throughout multiple parallel cross-sectional planes bisecting the intact thorax, with 1-mm spatial resolution and 60-per-second temporal resolution, and for generating time delay video and cine displays of the spatial and temporal sequences of these cross-sectional images. Operator-interactive computer programs facilitate the dynamic display of reconstructed cross sections of the heart and lungs, with or without dynamic background subtraction, and permit calculation and display of any desired single or spatially related set of coronal, sagittal or obliquely oriented sections. Such displays permit viewing of the temporal and spatial distribution of contraction, expansion, and perfusion of these organs over their full anatomic extent in various orientations and in variable time-base modes ranging from stop-action to real-time. The results achieved with this computerized system for three-dimensional reconstruction and display of moving organs, particularly the heart, lungs, and circulation, demonstrate the potential for providing greatly improved techniques for investigation of the relationships of the dynamic three-dimensional anatomy and blood-tissue exchange properties of moving organ systems to their regional and integrated function, and ultimately for providing powerful new clinical diagnostic methods for elucidation of abnormalities of the heart, lungs and circulation in man.","PeriodicalId":160433,"journal":{"name":"Proceedings of the 3rd annual conference on Computer graphics and interactive techniques","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122563307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The terminal comprises an integrated of hardware and software. While various choices are available for the actual input and output devices, the present prototype utilizes video display for both devices and a \"cross-wire\", touch-sensitive input panel. The EITS allows an \"author\" to define an essentially infinite set of symbols, and an infinite variety of \"keyboard\" formats. Chord inputs (i.e., simultaneous, multiple-\"key\" combinations) are also supported. Symbols can be defined in terms of dot matrices, generalized graphics, symbol strings, and functional operations. In spite of the complete generality afforded, the integrated system develops a standard-type of binary-bit-coded input stream, in which the individual symbols are uniquely and canonically represented, and which is amenable to all of the usual \"text-file\" operations, such as character manipulation, editing, transmission and re-display.","PeriodicalId":160433,"journal":{"name":"Proceedings of the 3rd annual conference on Computer graphics and interactive techniques","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121188525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
