Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to storing image data, such as medical images, in an image storage and retrieval device, searching and transmitting the same, and displaying face image information on an image display terminal device. The present invention relates to a management system, and particularly to an image information management system that can improve the transmission efficiency of a data transmission line.

2. Description of the Related Art Conventionally, medical images obtained using, for example, an X-ray imaging device, an X-ray tomography device, a digital subtraction angiography device, etc., have been developed and stored on film. However, especially in the case of medical uniforms, the number of images involved is enormous, and the storage space becomes large. Furthermore, it takes a lot of effort and time to extract a desired image from the huge number of images d. Therefore, images obtained with the various devices mentioned above are digitized and stored in a storage device without having to be developed on film one by one. When necessary, desired image data can be retrieved and the image displayed on an image display device. Now you can think of a display system.

In this case, data is transmitted and received between each device in order to store, search, and display image data, but in the conventional data transmission system, each of the above devices was connected by a single data transmission line. Image data itself and data other than image data, such as an image search request message and an identification code corresponding to the image, are commonly transmitted and received through this single data transmission line. That is, as shown in FIG. 4(,).

First search request message 2 on one transmission line 1
a is followed by the corresponding image data 3a, then the second search request message 2b, the corresponding image data 3b, and then the third search request message 2C, and so on. was being transmitted to.

Problems to be Solved by the Invention However, in such a data transmission system, image data, which has an order of magnitude larger data amount and a longer packet size, and non-image data, which has an extremely smaller amount of data and a shorter packet size, are separated. are transmitted and received in series over a single data transmission line 1, so when image data 3a, 3b with a long packet size is being transmitted, the data transmission line 1 is monopolized by the image data 3a, 3b, and during that time the packet size is Even short search request messages 2a to 20, etc., could not be transmitted. Therefore, the time required to transmit all of the data other than the image data (2a to 2c) and the image data 3a and 3b is equal to the time T required to transmit and receive each data in series. From this,
When image data with a long packet size is being transmitted, other data cannot be transmitted, resulting in poor transmission efficiency of the data transmission line 1 and a long response time of the system. Therefore, it takes time to search and display a desired image. Therefore, an object of the present invention is to solve such problems.

Means for Solving the Problems The means of the present invention for solving the above problems includes an image measurement device that digitizes and measures images, and image data measured by this image measurement device that is stored in a large-capacity storage device. an image storage and retrieval device that searches the stored image data, an image display terminal device that displays images searched by the image storage and retrieval device, and a data transmission line that connects each of the above devices to transmit and receive data. In the image information management system having the above-mentioned data transmission line, two systems are provided which are independent of each other, one data transmission line is configured to transmit only image data, and the other data transmission line is configured to transmit only data other than image data. This is done by making the transmission possible.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of an image information management system according to the present invention. This image information management system digitizes, for example, medical images, stores them in a storage device, searches for desired image data as needed, and displays the images on an image display device.One image measurement device 5 and 1 image storage and search device 6, image display terminal devices 7a and 7b,
First data transmission line 8a and second data transmission line 8
b. The image measurement device 5 measures one image by digitizing it, and is, for example, an xH tomography device,
Digital Subtraction Angiography (D
SA) equipment, nuclear magnetic resonance tomography equipment, etc. In addition,
Although only one image measurement device 5 is shown in FIG. 1, the present invention is not limited to this, and a plurality of various image measurement devices 5 may be connected.

The image storage and retrieval device 6 stores the image data measured by the image measurement device 5 and searches the stored image data, and as shown in FIG. , a main memory 10, a magnetic disk 11, an optical disk 12, and two interfaces 1.
3a and 13b. The magnetic disk 11 stores an identification code for searching image data, and the optical disk 12
is designed to store image data as a mass storage device. This is because, at present, data reading and writing time is shorter on magnetic disks than on optical disks, so image searches can be performed at high speed using the magnetic disk 11. Note that the optical disk 12 as a mass storage device is not limited to this, and may be replaced with a mass storage unit or a large-capacity magnetic disk. Also,
One interface 13a is the first data transmission line 8
It is a connecting part to a, and the other interface 13
b is a coupling portion to the second data transmission line 8b. The CPU 9 separates data other than image data, such as an identification code, and image data, and sends and receives data to and from the first and second data transmission lines 8a and 8b. For example, data other than image data is communicated with the first data transmission line 8a via one interface 13a, and image data itself is communicated with the second data transmission line 8b via the other interface 13b.

The image display terminal devices 7a and 7b are used to request the image storage and search device 6 to search for images and to display images resulting from the search, and as shown in FIG. CPU) 14, main memory 15, image display memory 16, display 17, magnetic disk 18, console 19, and two interfaces 20a and 20b.
It consists of

The operation console 19 is used to input search request data and a search identification code when searching and displaying images. Further, one interface 20a is a coupling portion to the first data transmission line 8a, and the other interface 20b is a coupling portion to the second data transmission line 8b. The CPU 14, like the CPU 9 of the image storage and retrieval device 6, processes data other than image data.

The data is transmitted and received separately from the image data to the first and second data transmission lines 8a and 8b. For example, data other than image data is communicated with the first data transmission line 8a via one interface 20a, and image data itself is communicated with the second data transmission line 8b via the other interface 20b. In addition, in FIG. 1, only two image display terminal devices 7a and 7b are shown.

The present invention is not limited to this, and any number of devices may be provided depending on the need for image search and display.

Each of the devices 115, 6, 7a, and 7b is connected in parallel to a first data transmission line 8a and a second data transmission line 8b, which are provided independently of each other. There is. These first and second data transmission lines 8a and 8b are used to separately transmit and receive image data or data other than image data between the respective devices 51617a and 7b. The second data transmission line 8b is configured to transmit only image data.

Next, the operation of the image information management system configured as described above will be explained. First, digital image data measured by the image measuring device 5 is registered in the image storage and retrieval device 6 via a data transmission line. At this time, the identification code of the image data is transmitted to the magnetic disk 11 of the image storage and retrieval device 6 via the first data transmission line 8a and registered at the corresponding address. Further, the image data itself is transmitted to the optical disk 12 of the image storage and retrieval bag fl16 via the second data transmission line 8b, and is registered at the corresponding address. Next, in order to search and display a desired image among the plurality of image data sequentially accumulated in the image storage and search device 6 in this way, first operate the operation console 19 of the image display terminal device 7a or 7b. and input the search request message and identification code for searching for the desired image. Then, this search request message and identification code are transmitted to the image storage and search device 6 via the first data transmission line 8a, decoded by the CPU 9, and the required search is performed. The identification code of the search result is also transmitted to the image display terminal device 7a or 7b via the first data transmission line 8a. Thereafter, the image data itself of the desired image retrieved and read out is transmitted to the image display terminal device 7a or 7b via the second data transmission line 8b, and the image is displayed on the display 17. .

The data transmission method of such an image information management system is
4(b) shows a comparison with the conventional data transmission method shown in FIG. 4(a).

That is, the first search request message 2a is transmitted via the first data transmission line 8a, and the corresponding image data 3a is transmitted through the second data transmission after decoding and searching the first search request message 2a. It is transmitted via line 8b. At this time, the above first search request message 2a
The second and third search request messages 2b and 2c following
Image data 3 corresponding to the first search request message 2a
Even if data a is being transmitted on the second data transmission line 8b, it can be transmitted continuously through the first data transmission line 8a without any time interval.

Further, the image data 3b corresponding to the second search request message 2b is decoded and searched while the image data 3a corresponding to the first search request message 2a is being transmitted, and the transmission of the image data 3a is completed. By the way, similarly, the data is transmitted continuously without any time interval via the second data transmission line 8b. Therefore, search request message 2a
, 2b.

Data other than image data such as 2c can be transmitted one after another through the first data transmission line 8a, and image data 3a and 3b can be transmitted one after another through the second data transmission line 8b. Data transmission is possible through parallel operation. From this, even when image data 3a and 3b, which have an order of magnitude larger data amount and longer packet size, are being transmitted, there is no waiting time for data other than image data (2a to 2c), which has a smaller data amount and shorter packet size. Can be transmitted. Then, data other than the above image data (2a to 2c
) and the entire image data 3a, 3b, the time required to transmit the entire image data 3a, 3b is reduced by the parallel operation (T2<TL), as shown by the symbol T2 in FIG. 4(b). Note that the single image display terminal devices 7a and 7b display the corresponding image data 3a.
Or, before 3b is transmitted, its identification code can be obtained via the first data transmission line 8a.

FIG. 5 is an explanatory diagram showing an example of the structure of a packet used for data transmission according to the present invention. FIG. 5(a) shows a packet of data other than image data such as search request messages 2a to 2c and identification codes, including a source address S, a destination address D, a data type α, a data order β, and an image. It is composed of data entities 21 other than data, error check codes 22 for checking these, and the like. Further, FIG. 5(b) shows a packet of one image data 3a, 3b, with a source address S, a destination address D, a data type X,
It consists of data order y, image data entity 23, error check code 24 for checking these, and the like. Incidentally, FIG. 5 shows an example of the packet structure; 1. Some packets are more complex than this.

FIG. 6 is a graph showing the optimum packet size for transmitting data in the shortest time when the data transmission error rate is constant on the data transmission line. However, it is assumed that the amount of data is sufficiently larger than the packet size. Note that a transmission error rate of 10" bits indicates the case of coaxial cable, and 10" bits indicates, for example, the case of optical fiber.This graph shows that the smaller the transmission error rate, the smaller the packet size. This shows that it is possible to increase the packet size, and it can be seen that it is advantageous to increase the packet size in the case of image data with a very large amount of data.In addition, in the present invention, it is advantageous to increase the packet size. Since the image data is transmitted separately through the data transmission lines 8a and 8b, the packet size of the image data can be made larger than in the past.

Effects of the Invention Since the present invention is configured as described above, 92 data transmission lines are provided independently from each other, and one data transmission line 8 is provided.
b transmits only image data.

By transmitting only data other than image data to the other data transmission line 8a, both of the data can be transmitted in parallel. Therefore, even when image data with an order of magnitude larger data amount and longer packet size is being transmitted, data other than image data with a smaller data amount and shorter packet size can be transmitted without waiting time. The time required to transmit the entire image data can be reduced. From this,
Data other than image data and image data can be transmitted one after another through the two data transmission lines 8a and 8b, and the transmission efficiency of the data transmission lines 8a and 8b can be improved, and the response time of the entire system can be reduced. Can be shortened. Therefore, the time required to search for and display a desired image can be reduced. Further, the optimum packet size can be determined for each of image data and data other than image data.
