摘要:
A medical information system has a terminal device of a hospital information system for retrieving and displaying an examination list and a reading report and an image display terminal device for displaying an image. Both terminal devices are arranged to mutually transfer the identification information of an examination to enable their displayed contents to be changed interlockingly. Therefore, medical information, such as charts, medical images, reading reports and results of examinations, required to perform a diagnosis is formed into electronic data and electronic data is displayed on a screen to provide information for a doctor.

A computerized tomography apparatus comprises a source rotating about an object for directing fan-shaped beams of radiation towards the object, a detector for detecting the fan-shaped beams of radiation through the object and producing projection data representative of radiation intensity integrated along the beams at successive different views, and estimating circuitry for providing interpolated projection data between adjacent views in addition to projection data from the detector by using a pipeline process to increase the number of projection data.
摘要:
A medical information processing system for supporting diagnostic interpretation, featuring a data storage unit for storing an interpretation image and interpretation reference images for which a doctor will refer to interpret the interpretation image. A data loading unit loads the interpretation reference images from the data storage unit into a workstation unit according to a predetermined priority order. The data loading unit loads the images into a workstation which is selected from the workstation unit according to workstation vs. interpretation examination modality information. A diagnostic information creation unit creates diagnostic information relative to the image by inputting the doctor's findings or computerizing with a computer unit. Positions of abnormalities and degrees of the abnormalities are determined, and positions in association with the images are calculated. A diagnostic information comparing unit compares the diagnostic information with each other and creates differences between the diagnostic information as time-sequential abnormality change data. A diagnostic information output unit outputs the diagnostic information or results of comparing the diagnostic information with each other and superimposes the contents of the time-sequential abnormality change data on the associated image. The diagnostic information output unit also outputs predetermined contents for an inconsistency of the diagnostic information for the doctor's findings with the diagnostic information for the results of computerizing and includes a plurality of displays and automatically determines relational positions in which the images are displayed on the displays according to a predetermined relational information.

An image processing apparatus includes a memory for storing image data, a loss-compression circuit for loss-compressing the image data, an expansion circuit for expanding the loss-compressed image data, and a difference circuit for calculating a difference between the original image data of the image memory and the expanded image data of the expansion circuit. A lossless compression circuit lossless-compresses the difference image data obtained by the difference circuit. A multiplexer multiplexes the loss-compressed image data output from the loss-compression circuit, with the lossless-compressed difference data obtained by the lossless-compression circuit.

A data processing device applied to a computed tomography system which examines a living body utilizing radiation of X-rays is disclosed. The X-rays which have penetrated the living body are converted into electric signals in a detecting section. The electric signals are acquired and converted from an analog form into a digital form in a data acquisition section, and then supplied to a matrix data-generating section included in the data processing device. By this matrix data-generating section are generated matrix data which correspond to a plurality of projection data. These matrix data are supplied to a partial sum-producing section. The partial sums respectively corresponding to groups of the matrix data are calculated in this partial sum-producing section and then supplied to an accumulation section. In this accumulation section, the final value corresponding to the total sum of the matrix data is calculated, whereby the calculation for image reconstruction is performed.

In a medical image data managing system, a directory managing unit is employed so as to manage directory data on overall medical image data. The medical image data managing system comprises: a plurality of modality units for producing medical image data in accordance with sorts of the modality unit a plurality of database units for storing at least the medical image data produced from the modality units: workstation units for issuing a demand to fetch desirable medical image data from the database units and for displaying the fetched medical image data; and, a directory managing unit for storing directory information about to which database units the desirable medical image data has been stored and for outputting the directory information upon receipt of the demand issued from the workstation means.
摘要:
A picture archiving and communication system comprises an image data output section, a terminal station, and a plurality of data bases. The image data output section produces diagnostic image data in accordance with examination requests made at a plurality of diagnosis departments, and outputs the diagnostic image data together with appendant data (which includes destination data indicating where the image data should be sent). From the terminal station are entered specific data used for specifying the image data produced by the image data output section, and destination data representing where the image data should be sent. The data bases are located at various diagnosis departments. On the basis of the data entered from the terminal station, a register list is prepared at each of the data bases, and the appendant data supplied from the image data output section is collated with the data recorded in the register list. In accordance with the results of the collation, image data is selectively stored in the data bases.
摘要:
A database system is provided in a network system capable of exchanging medical data, including at least image data and key data associated therewith, and can store and retrieve the medical data via the network system. The database system has first and second data file devices and a file management device. The first data file device stores image data supplied via the network system in a first rewritable storage. The second data file device stores image data transferred from the first storage in a non-rewritable second storage. The file management device has an index data storage for storing the key data, supplied via the network system, and memory addresses of image data, which correspond to the key data, on the first and second storages in correspondence with each other, and manages storing and reading of the image data in and from the first and second data file devices.
摘要:
An auto changer apparatus for an optical disk, having a large number of optical disks which are contained in a shelf, and one of which is selected and picked up by an arm mounted at a disk installment unit, and is installed in a disk drive unit, includes a defect control memory and a directory memory. The defect control memory stores defect control data of each optical disk as a table. Upon an initial operation. initial defect control data is transferred from a control block of the optical disk to the defect control memory, and an initial defect control table is made. If a defective block is found in a write mode or a read-after-write mode, data associated with the defective block is stored in the defect control memory, and the defect control table is updated. The directory memory stores a correspondence table of a logical address of the auto changer apparatus and a physical address of each disk. The auto changer apparatus performs a pre-process such a substitute processing for a defective block and making of a directory in accordance with the data in the defect control table and the data in the directory memory upon access to the disk.
