Abstract

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.

Claims

1. A medical image data managing system, comprising:

a plurality of modality units, each for producing medical image data in accordance with a type of said each modality unit;

a plurality of database units, connected to said plurality of modality units, for storing at least said medical image data produced by said modality units, each of said plurality of database units storing a group of related medical image data from said medical image data producing by said modality units;

directory managing means for storing directory information indicating where the medical image data produced by the modality units is stored in said database units;

workstation means for issuing a demand, to the directory managing means, to fetch desired medical image data, which corresponds to the demand, from said database units and for displaying the fetched medical image data; and

,

wherein said directory managing means includes at least a first directory managing unit associated with a first of said plurality of database units and a second directory managing unit associated with a second of said plurality of database units, whereby when said demand issued from said workstation means is supplied to one of said first and second directory managing units within the directory managing means and said one directory managing unit determines that the desired image data corresponding to said demand is not contained in said database associated with said one directory unit, said one directory managing unit retrieves the image data corresponding to said demand from the database unit associated with the other of said first and second directory managing units, if said other of said directory managing units contains directory information corresponding to said demand.

2. A medical image data managing system as claimed in claim 1, further comprising:

a local area network for mutually connecting said modality units, database units, workstation means, and directory managing means so as to establish medical image data communication therebetween.

3. A medical image data managing system as claimed in claim 2, wherein said workstation means includes at least a command process unit for automatically supplying said demand issued therefrom via the local area network to said directory managing means.

4. A medical image data managing system as claimed in claim 1, wherein said directory managing means includes:

a directory filing/processing unit for instructing said database units to file said produced medical image data produced by said modality units, into said database units; and

a directory retrieving/processing unit for instructing said database units to retrieve said desired medical image data therefrom thereby to receive said retrieved medical image data.

5. A medical image data managing system as claimed in claim 1, wherein said modality units includes at least one of an X-ray computerized tomographic apparatus, and a magnetic resonance imaging apparatus.

6. A medical image data managing system as claimed in claim 1, wherein said database units each include at least a database retrieving/processing unit, a database filing/processing unit and a database data unit, whereby said medical image data produced by said modality units is filed in said database data units under control of the database retrieving/processing unit thereof and the database filing/processing unit thereof.
