Returning to FIG. 5, when the MO disk device 95 is notified that the MO disk is mounted, as will be described below,
The CPU 86 reads the directory information from the MO disk device 95 and stores it in the DRAM 91.

At the time of recording, the patient ID is input with the ten key 22 of the remote control unit, and the ID recording key 35 is pressed. Further, the capacity selection key 30 is pressed to select the capacity mode, that is, large capacity (mode 4), standard (mode 3), semi-high image quality (mode 2), or uncompressed (mode 1).

By the above key operation, the CPU 86 generates a character video signal for displaying the disk ID, the input patient ID, and the capacity mode, supplies the character video signal to the character mixing circuit 79, and displays it on the monitor 43. The character display according to such a key operation is similarly performed at the time of a search described later.

Further, the CPU 86 starts the recording process shown in FIG.

In FIG. 8, the patient ID number input in step S2 is registered in the SRAM 88, and the serial number of the SRAM 88 is initialized to 1 in step S4. Then step S
At 6, the key input from the remote control unit 97 is determined. When the record key 36 is pressed, the process proceeds to step S8, and the directory information of the image to be recorded such as the input patient ID number additional number, date and time, time is stored in the SRAM8.
Register at 8. Next, in step S10, the image data from the A / D converter 56 is written in the input image memory 73 (freeze). Thereafter, in step S12, it is determined whether or not it is the compression mode. If it is the compression mode, the compression / expansion circuit 75 compresses the image data in the input image memory 73 in step S14.

In step S16, the compressed image data or the image data from the input image memory 73 is transferred to the DRAM 9

The directory information registered in 8 updates the directory information corresponding to the recorded image in the DRAM 91. At this time, the FAT start number image, the file data size, the actual file size, etc. are also written, and the updated directory information (DIR) of the DRAM 91 and the FAT corresponding to the area in which the image data is recorded are written and updated in the MO disk device 95. After that, in step S22, the table element of the ID table in the SRAM 88 is added and the table element of today's date in the date and time table is added, or if there is a table element of today's date, the final address of the directory is rewritten. Update and add 1
Only increments and proceeds to step S6.

In this way, a plurality of images are recorded in the MO disk device 95 as shown in FIG. 9 (A). At this time, the address number of each image in the directory information increases in the order of recording. Images recorded consecutively with the same date form a date block, and images recorded consecutively with the same patient ID and date form a block. Within each block, the serial number of each image is in the recording order. Increase from 1.

The CPU 86 also creates a search ID table and date table in the SRAM 88 based on the directory information in the DRAM 91. Figure 9 shows the ID table
As shown in (B), the table element is configured in block units, and each element is composed of the start address (start address) in the DRAM 91 of the directory information of the image whose serial number is 1 in the block and the number of images. In other words, even if the patient ID is the same, if the dates are different, a plurality of table elements are arranged in the table in ascending order of date.

In the date table, as shown in FIG. 9C, table elements are composed in units of dates, and the start address (head address) in the DRAM 91 of the directory information of the leading image on the same date and the date. It consists of the start address (final address) in the DRAM 91 of the directory information of the final image. This table element is ordered by date.

If it is determined in step S6 in FIG. 8 that the stop key 27 has been pressed, the pointer instructing the registration position of the table element of the ID table is incremented in step S24, and the process ends.

By the way, in the case of a patient such as an emergency patient whose patient ID number has not been decided, the ID record key 35 is pressed without inputting the patient ID. In this case, the CPU 86 inputs the patient ID
Is all "9" and monitor display and image recording are performed.

In the direct search, the address number is input with the ten key 22 of the remote control unit and the address search key 33 is pressed. As a result, the CPU 86 is a DRAM

Read data and DR
Write to AM91. Next, the image data read from the DRAM 91 is passed through the image data interface 76, or decompressed by the compression / decompression circuit 75 at a ratio according to the attribute of the directory information and written in the display image memory 74. The image data read from the display image memory 74 is converted into an analog composite video signal by the D / A converter 70, output from the terminal 81, and displayed on the monitor 43.

10 and 11 are flowcharts of the ID list search process. In FIG. 9, step S30
When the ID list key 31 is pressed in step S32, the directory (DIR) head address is fetched from all the elements of the ID table in step S32, and the patient ID number is fetched from the directory information designated by the respective head addresses in the DRAM 91 in step S34. Next, the patient ID numbers extracted in step S36 are sorted in ascending order in the SRAM 88, and in step S40, a list of patient ID numbers is displayed with a block number (NO) in the sort order as shown in FIG. It is displayed by the controller 92.

The desired patient ID number is searched from this list, and the block number is input in step S42 to input I

As shown in FIG. 2 (B), a block number is added and a list of dates and the number of sheets is displayed on the display controller 92.

When a desired date is searched from this list and the block number is input in step S50 and the search key 34 is pressed, the ID table is referred to by the date of the block number and the patient ID number designated in step S52. , Get the directory start address from the referenced table element. In the next step S54, the DRAM 91
The FAT start number image and the file data size are extracted from the directory information designated by the top address of the F disk, and in step S56, the F disk from the MO disk device 95 is read.
The image data of the image designated by the AT start number image and the file data size is read out and stored in the DRAM 91.

Next, in step S58 of FIG. 11, it is judged from the directory information referred to in step S54 whether or not the image data is compressed, and if it is compressed image data, it is expanded by the compression / expansion circuit 75 in step S60. . In step S62, the expanded image data or D
The image data stored in the RAM 91 is written in the display image memory 74. In step S64, the display image memory 7
The image data is sequentially read from 4 and this image data is D
The analog / analog converter 70 converts the analog signal into a composite video signal, which is output from the terminal 81 and displayed on the monitor 43.

13 and 14 are flowcharts of the date list search process. In FIG. 12, step S7
When the date list key 32 is pressed at 0, the directory (DIR) is selected from all the elements of the date table at step S72.
The head address is taken out, and the DRAM 9
The date is extracted from the directory information designated by each of the above-mentioned start addresses of 1. Next, in step S76, FIG.
As shown in (A), a block number (NO) is added and a list of dates is displayed by the display controller 92.

When a desired date is searched from this list, the block number is input in step S78 and the date list key 32 is pressed, the date is obtained by referring to the date table with the date of the block number designated in step S80. The directory start address and the directory end address are extracted from the table element. The start address and the final address are compared with the directory start address of the ID table to find a matching table element, and from the table element of the ID table matching the starting address to the table element of the ID table matching the final address. The directory start address and the number of sheets of each included table element are extracted.
In step S82, the patient ID number is taken out from the directory information designated by each of the above-mentioned head addresses of the DRAM 91, and in step S84, a block number is added as shown in FIG. Is displayed on the display controller 92.

When a desired patient ID number is searched from this list, the block number is input in step S86 and the search key 34 is pressed, the ID table is displayed with the date of the block number and the patient ID number designated in step S88. The directory start address is extracted from the referenced table element. DR in next step S90
The FAT start number image and the file data size are extracted from the directory information designated by the head address of the AM 91, and the image data of the image designated by the FAT start number image and the file data size is read from the MO disk device 95 in step S92. It is stored in the DRAM 91.

Next, in step S94 of FIG. 14, it is judged from the directory information referred to in step S90 whether or not the image data is compressed, and if it is compressed image data, it is expanded by the compression / expansion circuit 75 in step S96. . In step S98, the expanded image data or D
The image data stored in the RAM 91 is written in the display image memory 74. In step S100, the image data is sequentially read from the display image memory 74, and this image data is output from the terminal 81 which is analogized by the D / A converter 70 and converted into a composite video signal and displayed on the monitor 43.

By the way, at the time of diagnosis by the ultrasonic diagnostic apparatus, ten or more images are recorded by one diagnosis, and these images form a block. The dozens of images are diagnostic images obtained at a plurality of positions determined for each part on the body to be diagnosed, and the order of diagnosis is also determined. Therefore, the order in which the images forming the block are reproduced and viewed is often the same as the order in which they are recorded, and a function of locating the first image in the block, that is, the image with the additional number 1 is required.

FIG. 16 shows a flowchart of a block search process for locating the first image in a block.

In the figure, in step S110, the key input from the remote control unit 97 is determined.
If the preview key 25 is pressed for 1 second or longer, the process proceeds to step S112, and if the next key 26 is pressed for 1 second or more, the process proceeds to step S114.

In step S112, the ID of SRAM 88
On the table, the directory start address is extracted from the table element of the block containing the image currently being reproduced. In step S114, the ID of SRAM 88
An address of directory information (DRAM 91 corresponding to the last (end) image of this block is referred to by referring to the directory start address and several images from the table element of the block including the image currently reproduced on the table.
Calculate). Since the directory information for one image is constant at 64 bytes, the above address calculation does not require any time. Step S112 or S114 above
D in step S116 using the address obtained by
The FAT start number image and the file data size are retrieved by referring to the directory information in the RAM 91, and the image designated by the FAT start number image and the file data size, that is, the head or last image of the block is fetched from the MO disk device 95 in step S118. The image data is read out and stored in the DRAM 91.

In the next step S120, step S11
It is determined from the directory information referred to in step 6 whether or not the image data is compressed, and if it is compressed image data, it is expanded by the compression / expansion circuit 75 in step S122. In step S124, the expanded image data or D
The image data stored in the RAM 91 is written in the display image memory 74. In step S126, the image data is sequentially read from the display image memory 74, and this image data is output from the terminal 81 which is analogized by the D / A converter 70 and converted into a composite image signal and displayed on the monitor 43.

Next, the change of the patient ID number in the directory information recorded with all the patient ID numbers being "9" will be described.

When the patient ID number of the emergency patient is determined, the renumbering process of FIG. 17 is executed.

In FIG. 17, in step S130, an image whose patient ID number is not changed is searched and reproduced. This may use either a direct search, an ID list search, or a date list search. Next, in step S132, the patient ID to be changed is input using the ten-key pad 22, and in step S134, the ID EDIT key 21 is pressed.

This operation causes the CPU 86 to execute step S1.
By 36, the patient ID number of the directory information of the image currently reproduced on the DARM 91 is rewritten with the input patient ID, and the serial number is rewritten with 1. Further, regarding the directory information of the image subsequent to the image currently being reproduced among the images forming the block having the same patient ID and date as the image currently being reproduced, the patient ID number is input.
And rewrite so that the serial numbers are serial numbers, that is, 2, 3, 4, ...

Next, at step S138, the changed directory information on the DRAM 91 is transferred to the MO disk device 95.
To rewrite the directory information of the MO disk. Further, in step S140, the table element in which the patient ID has been rewritten in the ID table in the SRAM 88 is changed, and the process ends.

By the way, assuming that there are, for example, 10 images constituting a block having the same patient ID and date, if the renumbering process is executed in the state where the image with the serial number 5 is being reproduced, the above 10 images will be obtained. The images of which the serial numbers are 5 to 10 form the new patient ID block, the number of blocks is increased by 1, and the number of table elements on the ID table is increased by 1.

In this way, the image data and the directory information are recorded in the same MO disk device, and the system can be integrated into a single device, and the configuration can be simplified.

Further, since a series of a plurality of images related to each other obtained by one diagnosis for one patient are divided into blocks and managed by the ID table, the blocks can be formed by referring to the ID table. By obtaining the directory information of the first image of the created multiple images,
The first image can be reproduced, that is, the cue reproduction can be performed.

[0067]

As described above, according to the image filing apparatus of the present invention, the first image of a plurality of images obtained in each diagnosis can be searched for and reproduced, which is extremely useful in practice.
