21 May 1986TL;DR: In this paper, the position of the document image data with memo is brought into alignment with the original document image and correlated to extract only that memo data which has been written by hand.
Abstract: In order to utilize memo data written by hand for purposes of retrieving a document, the original document image data is stored and, thereafter, a document image data with memo is separately input, the document image data with memo being comprised of the original document image onto which is additionally written memo data by hand. The position of the document image data with memo is then brought into alignment with the original document image data and is correlated to extract only that memo data which has been written by hand. Then the kind of memo is discriminated, the process is effected depending upon the kind of memo, and the memo data is stored in a secondary data file for retrieval. To retrieve the document, the memo data of a plurality of documents is read out from the secondary data file depending upon the kind of memo that is designated, and is displayed as a look-up table. If the operator designates any one of them, the image of the corresponding original document is read out from the original document image file and is displayed.

TL;DR: The Utah Raster Toolkit is a set of programs for manipulating and composing raster images based on the Unix concepts of pipes and filters, and operates on images in much the same way as the standard Unix tools operate on textual data.
Abstract: The Utah Raster Toolkit is a set of programs for manipulating and composing raster images. These tools are based on the Unix concepts of pipes and filters, and operate on images in much the same way as the standard Unix tools operate on textual data. The Toolkit uses a special run length encoding (RLE) format for storing images and interfacing between the various programs. This reduces the disk space requirements for picture storage and provides a standard header containing descriptive information about an image. Some of the tools are able to work directly with the compressed picture data, increasing their efficiency. A library of C routines is provided for reading and writing the RLE image format, making the toolkit easy to extend. This paper describes the individual tools, and gives several examples of their use and how they work together. Additional topics that arise in combining images, such as how to combine color table information from multiple sources, are also discussed.

TL;DR: In this paper, the authors proposed an image storage means which reproduces an input image hierachically in order, a storage means that stores file control information on the input image, a means which allows said storage means to perform registration processing and retrieval processing, and a means that displays a title image consisting of an original image and part of said reproduced image.
Abstract: PURPOSE: To improve the use efficiency of storage capacity by providing an image storage means which reproduces an input image hierachically in order, a storage means which stores file control information on the input image, a means which allows said storage means to perform registration processing and retrieval processing, and a means which displays a title image consisting of an original image and part of said reproduced image. CONSTITUTION: When registration is performed, input image data is stored temporarily in an image memory 33 and then transferred from the memory part 53 to a data storage part 36 with a registration command from a main control part 30, and this original image data 4 is recorded hierachically in a data storage part 1 in the storage part 36 after hierachic sequential recording and reproduction processing 2. The file control information consists of recording position information on the data, control data, and an image number and is recorded every time the hierachic data is recorded. When retrieval is performed, the main control part 30 reads the file control information on the title image out of the storage part 36 in response to its indication to obtain the storage position of hierachic data to be reproduced from reproduced hierachic data of the control information, reads its reproduced data out of the storage part 1, and reproduces the corresponding image data hierachically by recording and reproduction processing 2. Thus, the image data is recorded hierachically and successively so that it can be reproduced, and consequently the title image consists of part of its reproduction data, so that the title image need not be recorded individually.

TL;DR: The goal of this project was to develop a prototype to demonstrate the use of video and graphic techniques applied to the human-machine interface for data retrieval from a typical computerized database.
Abstract: The goal of this project was to develop a prototype to demonstrate the use of video and graphic techniques applied to the human-machine interface for data retrieval from a typical computerized database. Data is presented to a user via video and graphic means; queries are formulated in one of several graphic formats; control operations are handled through joystick, touch panel, or single-keystroke maneuvers. To accomplish this, we made use of videodisc, interactive computer graphics, and relational database technologies. Still pictures, video segments, and pictures of text are used as visual cues to a user who indicates interest in a data item in a pointing gesture by touching the panel through which the item may be seen. The user may find the actual data item s/he desires, then pose a query for additional information in one of four graphic query formats. A specially designed database was developed to handle the video and graphic data needed for this user facility.

TL;DR: The main purpose of this paper is to describe what a raster display looks like from the point of view of the programmer and to define the specific hardware and software data about the rasterdisplay that must be known in order to implement the small set of primitives.
Abstract: Two major difficulties associated with medical image processing are the diverse image formats that must be dealt with because of the differences in image sources and the number of incompatible display systems available for viewing images both before and after processing. We describe a very small set of primitives that need to be defined to utilize any raster display. When these primitives have been implemented for a particular device, then a standard set of image display programs can be compiled and images and the results of image processing can be displayed. The main purpose of this paper is to describe what a raster display looks like from the point of view of the programmer and to define the specific hardware and software data about the raster display that must be known in order to implement the small set of primitives.

Abstract: PURPOSE:To input an image information and check the image in parallel by transmitting the image information inputted from an image input device to an image information recording means and an image forming section simultaneously by an image information transmitting control means. CONSTITUTION:A CPU40 discriminates whether an inputted command from a keyboard 39 is a registering command of an image information or a retrieving command. If it is the retrieving command, a retrieval code of the image information from the keyboard 39 is waited, whether the image information coinciding with the inputted retrieval code exists in the image files 24, 27 or not is examined, and if it is present therein, the image information is read from the files 24, 27 to do a CRT display 28. If the inputted command is registering command, a reading of the image information is started from a copy reader 22, a read image information is fed to a RAM42 and together to a soft display 26 and the read image information is displayed on the soft display 26. Then, whether a density of the image on the display 26 is proper or not is judged, and if it is proper, the retrieval code relative to the image information inputted from the keyboard 39 is inputted to complete a registration control.

TL;DR: This report focuses on the developmental work on the image file indexing subsystem and its communications protocol with the image filing subsystem, which comprises what will become the central element of the in-house PACS.
Abstract: We are developing an in-house Picture Archiving and Communication System (PACS) targeted to the centralized storage of images acquired from our computer-assisted imaging modalities and to the display of these images on multi-modality viewing stations. The central image database is distributed between two system modules with image processing capabilities located at the viewing stations. The first module of the image database is an image filing subsystem used for the storage and retrieval of complete image files. In our initial work, this module consists of a Data General MV/6000 computer system with 1.16 Gbytes of on-line disk storage. However, more efficient dedicated filing systems may be substituted for this general purpose computer in future revisions. The second module is an image file indexing subsystem which has been implemented on a DEC PDP-11/44 computer and is tightly integrated with our MARS II (ADAC Laboratories) Radiology Information System. These two image database modules communicate via low-speed, serial communications lines. This report focuses on our developmental work on the image file indexing subsystem and its communications protocol with the image filing subsystem. The image file indexing subsystem automatically inserts image file locators for studies referenced by patient when an image is transmitted from the acquisition device (eg, CT) to the image filing subsystem. It also locates image files at the request of a viewing station user based on patient name, physician name, or study type for either read or unread studies. Other capabilities include cross-referencing patient attributes with the MARS II system, deleting studies based on predefined criteria, storing requests for hard copy, storing user selected image processing attributes for individual images, flagging the archival status of an image, and complete managerial functions. This central-ized image filing and indexing system comprises what will become the central element of our PACS.

TL;DR: In this article, a registerable data per unit medium, and to execute easily a registering work by reading an original of plural pages by once, registering a read data as one file of a fundamental constitution of a file, and giving index information at every one page of the original.
Abstract: PURPOSE:To increase registerable data per unit medium, and to execute easily a registering work by reading an original of plural pages by once, registering a read data as one file of a fundamental constitution of a file, and giving index information at every one page of the original. CONSTITUTION:A book registering mode, a size of an original and a position for diving the original are set by an operating part of a keyboard 31 or an original reader 2. The original which has been read by the reader 2 is developed on a RAM34 by having a continuous address as a serial data. In order to divide a page, an (n) address of the head address in which the second page begins is divided by a CPU32, and thereafter, index information for calling separately the data of the first page and the second page is registered in an image file 4. Subsequently, the data of the first page and the second page on the RAM are registered in the image file 4 as continuous image information, and also as the same file. In this way, one page each can be called separately and directly, and also the number of registerable sheets per unit recording medium is improved.
