Abstract

PURPOSE:To easily record a necessary medical image on an optical disk without loading any load on a modality side by providing a control means which adds a recording table where a flag which indicates whether or not the same image is filed on the optical disk is set. CONSTITUTION:The control means 1 files the medical image on a magnetic disk 8 and also adds the recording table wherein the flag indicating whether or not the same image is filed on the optical disk 10 is set. Then a flag indicating whether or not the same image is recorded on the optical disk 10 is set on condition that the medical image is recorded on the magnetic disk 8 is set and this flag is confirmed to know whether or not the same image is recorded on the optical disk 10. Therefore, only the necessary medical image can be recorded on the optical disk on the side of the file device. Consequently, no load is placed on the modality side.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention 1 (Field of Industrial Application) The present invention relates to a medical image file device for filing medical images on an optical disk or a magnetic disk.

(Prior Art) A medical image file device that transmits medical images obtained by various image generating devices (modalities) such as a CT device or a CR device online from a mogrity side and is equipped with a storage medium such as an optical disk or a magnetic disk. Files (recordings) and management are performed. When storing medical images as files on optical disks or magnetic disks,
Optical disks are used for long-term storage, ie, databases, and magnetic disks are used for short-term storage.

(Problem to be Solved by the Invention) However, in conventional medical image file devices, when transmitting medical images to an optical disk, if the optical disk becomes unable to record for some reason, it is necessary to repeat the operation of transmitting the image again. Therefore, there is a problem that the operation becomes complicated. For example, if the optical disc is in a state where there is no empty area, it is being used by someone else, or it has not been set, it is in a recording impossible state and no medical images can be recorded, resulting in an error. For this reason, it is necessary to repeat the operation of transmitting online again after confirming that the recording is possible after a certain period of time. This places a burden on the modality side, and even if you try to transmit it again, the medical image that should be transmitted is not necessarily stored on the modality side, and may be lost due to operational error etc. . Furthermore, this will lead to a decrease in the reliability of the entire device.

The present invention has been made in response to these circumstances, and it is an object of the present invention to provide a medical image file device that can solve the conventional problems.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention files a medical image on a magnetic disk and files the same image on an optical disk.
7 is provided with a control means for adding a recording table in which a flag is set indicating whether or not the data has been filled.

(Function) In a medical image file device that manages images recorded on an optical disk as a database, a flag is set to indicate whether a medical image is recorded on a magnetic disk and the same image is also recorded on the optical disk. By checking this flag set on the magnetic disk, it is possible to know whether the same image has been recorded on the optical disk. As a result, if the medical image is not recorded, the medical image can be transferred from the magnetic disk to the optical disk. Therefore, only the necessary medical images can be recorded on the optical disk on the file device side, so there is no burden on the modality side.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the medical image file device of the present invention. A central processing unit (CPU) 1 consisting of a microprocessor is in charge of overall control operations. Various medical images obtained by various image generators (modalities) 2 are transferred to the transmission line 3.1/F.
(Interface)4. The image is recorded once in the image memory 6 via the data bus 5. Subsequently, under the control of the CPU 1, the medical images in the image memory 6 are output to the data bus 5, and are output to the magnetic disk 8 or the optical disk 10, respectively, or to both disks 8, 10 via the I/Fs 7, 9 as necessary. Will be recorded. FIG. 2 shows a case in which the medical images output from the image memory 6 are recorded on the necessary disks, and FIG. 2(a) shows the case where the medical images are recorded only on the magnetic disk 8. In this case, FIG. 2(b) shows a case where medical images are recorded only on the optical disk 10, and FIG. 2(C) shows a case where medical images are recorded on the magnetic disk 8 and the optical disk 10.

When medical images are recorded in this way, a PCB (file control block) record in the format shown in Figure 3 is added to the magnetic disk 8 corresponding to each image, and part of this PCB record is A flag section 13 indicating whether or not the image is recorded on the optical disc 10 is set. The flag section 13 is set to have a length of 1 byte between 7 and 8 bytes, for example. The contents of this flag are determined according to the recording results of medical images on the magnetic disk 8 and optical disk 10, as shown in Table 1 below.

On the other hand, if the recording to the magnetic disk 8 is successful and then the recording to the optical disk 10 is successful, O' is displayed, and if the recording to the optical disk 10 is unsuccessful, "F'or"■
' is displayed. Here, the pronunciation is the ID of the corresponding medical image.
, if the failure is due to a name mismatch, "[′" indicates a failure due to a cause other than "bi".

Table 1 Therefore, by checking the contents of this flag, it is possible to know whether each medical image is recorded on the optical disc 10 or not. For example, only cases where O' is displayed, such as in case No. 1, are recorded on the optical disc 10 (as well as on the magnetic disc 8). In this way, recording to optical disc 10 failed (Case No.
3), the corresponding medical image can be manually transferred from the magnetic disk 8 to the optical disk 10 later under the control of the CPU 1.

Incidentally, even when a medical image is recorded independently on the magnetic disk 8, the recording result can be shown as a flag as shown in Table 2 below.

For example, it can be seen that only cases where . . . are displayed, such as case No. 011, are recorded on the magnetic disk 8. Note that "" represents a blank character (space).

Also, * means that recording to the magnetic disk 8 has failed, so not only is the flag not set, but the PCB record itself is not set.

Figure 4 shows a PCB corresponding to one image as shown in Figure 3.
This table shows a table in which records are consecutively set in the magnetic disk 8, and Rec1, 2°3, . . . correspond to each of a plurality of images.

It should be noted that each medical image recorded on the magnetic disk 8 or optical disk 10 is read out under the control of cpul as necessary. /F11 to be displayed on the dayplay 12.

Next, the operation of this embodiment will be explained with reference to flowcharts 1 to 1 in FIG.

First, in step A, it is determined whether recording of medical images on the optical disk 10 is necessary, and if necessary, the process advances to step day. If not, jump to step D. Step B
The medical image taken out from the image memory 6 is recorded on the optical disc 10 via the I/F 9 under the control of the CPUI. Subsequently, in step C, it is determined whether the recording onto the optical disc 10 has been successful or not, and if the recording has been successful, the process proceeds to step D. If recording fails, jump to step E.

In step D, it is determined whether or not recording onto the magnetic disk 8 is necessary, and if so, the process proceeds to step E.

If not, jump after step J. Step F
The image is taken out from the image memory 6 under the control of the CPU 1 and recorded on the magnetic disk 8 via the medical image I/F 7. Subsequently, in step F, it is determined whether or not the recording to the magnetic disk 8 has been successful. If the recording has been successful, the process advances to step G. If recording fails, jump after step J.

In step G, the recording results on the optical disc 10 are determined based on Table 19 and Table 2 above. If recording to the magnetic disk 8 and optical disk 10 is successful, this corresponds to case 1 in Table 1, so proceed to step H. If recording to only the magnetic disk 8 is successful, but recording to the optical disk fails, then proceed to step H. Since this corresponds to case 3 in Table 1, proceed to step ■. If the recording is successful on the magnetic disk 8 alone, this corresponds to case 1 in Table 2, and the process proceeds to step J.

According to this embodiment, when a medical image obtained on the modality side is transmitted to the file device via the transmission line and recorded on the magnetic disk 8 and optical disk 10, the magnetic disk 8 is recorded as shown in FIG. Magnetic disk 8 as shown
By adding a recording table in which a flag is set to indicate whether or not the same image that was filed on the optical disk has been filed on the optical disk, it is possible to determine which image is recorded on the optical disk by checking the contents of this flag. You can easily find out if there are any. Therefore, images that are not recorded on the optical disk 10 can be manually transferred from the magnetic disk 8 to the optical disk 10 and recorded later. This allows only necessary medical images to be recorded on the optical disc 10 on the file device side, thereby eliminating any burden on the modality side. Furthermore, since retransmission from the modality side is unnecessary, there is no risk of the medical image being lost, and this prevents the reliability of the entire apparatus from being compromised.

[Effects of the Invention] As described above, according to the present invention, the magnetic disk is provided with a recording table including a flag indicating the recording result of medical images on the optical disk. It became clear that there was a failure in recording the
If recording to the optical disk fails, recording to the magnetic disk is performed, so necessary medical images can be easily recorded to the optical disk without placing any burden on the modality.
