Description

[Detailed Description of the Invention] [Technical Field] The present invention records medical image information obtained from, for example, an endoscope device on a first medium with a small storage capacity, and reproduces the stored information on these media. The present invention relates to a medical image information recording and reproducing device f which records this information on a second medium having a large recording capacity.

[Prior art]

Conventionally, in this type of medical image information recording and reproducing device, for example, when recording all medical image information (optical image) obtained from an endoscope device, it is recorded (photographed) on a silver halide film.
This is then developed and printed, stored, and reproduced (projected) as needed to obtain medical information.

Storage and retrieval of records using this method has the following problems. That is, a long time is required from recording to storage by printing.

Therefore, there is a drawback that the contents of the recorded image information cannot be confirmed for a long time until it is played back.

Furthermore, there is a problem in that image information is lost due to inappropriate processing during chemical processing steps such as photographing, developing, and printing such images. Furthermore, there is also the drawback that searching requires complicated work.

Recently, various electronic file systems for image information have been proposed. However, no recording/reproducing device having an information file function suitable for medical use has been proposed.

〔the purpose〕

A first object of the present invention is to provide image information that is edited and then recorded when all medical image data stored in a first recording medium with a small storage capacity and a second recording medium with a large storage capacity is recorded. An object of the present invention is to provide a recording/playback device.

A second object of the present invention is to provide an image in which auxiliary data such as identification data for identifying the image data is superimposed and recorded when the image data is recorded on the second recording medium. Our goal is to provide complete information recording and reproducing equipment.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows a medical image information recording and reproducing apparatus 100 of the present invention.
1 is a block diagram showing the entire system of one embodiment of the present invention.

This example shows a recording/reproducing apparatus 100'IH endoscope system f of the present invention.
It is a combination of llO.

First, the configuration of the endoscope device 10 will be briefly described.

This endoscope device 10 includes an image guide section 12, an operation section 14, a light guide section 16, a light source device 18, and a camera section 20. To explain the internal functions of this light source device 18, during normal diagnosis, a mirror (not shown) is tilted toward the collation lamp (not shown), and one end of the light guide section J6 made of glass fiber is opened. The collation light is emitted from the distal end portion 17 to the outside through a light guide optical path provided inside the operating portion 14 and the image guide portion I2.

On the other hand, when the image guide section 12 is inserted through its distal end 17 into the body cavity of a patient (not shown), an optical path separate from the fiber optical path of the light guide section 16 described above is formed. Fiber image guide part 1
An observed image of the inside of the body cavity irradiated with the collation light is introduced from the distal end portion 17 to the camera portion 20 through the optical path No. 2. Here, this observed image is converted into an electrical signal by a solid-state image sensor (not shown), and a first recording/reproducing device 3 with a small recording capacity, which will be described later,
It is designed to transfer to 0.

Next, the recording/reproducing apparatus 100 of the present invention will be described in detail.

This device 100 mainly includes a first recording/reproducing device 30 with a small recording capacity and a second recording/reproducing device 50 with a large recording capacity and incorporating a processing circuit 40 for processing a reproduction signal from the recording/reproducing device 30. ing.

First, the first recording/reproducing device 30 uses a small magnetic recording sheet 32.
The image information signal transferred from the camera unit 20 of the endoscope apparatus 10 is recorded on this sheet 32 using the . In this case, the site selection methane 21 to 23 provided in the camera section 20
Electrical signals selected by the patient and representing the entire duodenum, for example, are recorded in combination with the above-mentioned image information system. Generally, observation images of 50 still photographs (that is, equivalent to 50 TV frames) are used as this image information, to which a site group is added and recorded on the small recording sheet 32. Furthermore, the patient data input circuit 38 records auxiliary data such as a patient name and a search signal on the recording sheet 32.

Next, the image information signal reproduced by the first recording/reproducing device 30 is subjected to predetermined processing in a processing circuit 40 (described later), predetermined search data is added, and the image information signal is optically recorded by the second recording/reproducing device 50. The information is optically recorded on the disk 52. Generally this f
4 disk 52 is abbreviated as "P-optical disk", so this name will also be fully adopted for -C in this specification.This optical disk 52 has a considerably larger recording capacity than the above-mentioned small magnetic recording sheet 32. For example, about 10
There is a recording capacity of 0 sheets 32. In other words, image information for approximately 100 patients is recorded.

Next, the processing circuit 40 shown in FIG. 2 will be explained with reference to FIG. 1.

As described above, image data of, for example, the patient's duodenum has already been recorded on the image track 34 by the first recording/reproducing device 30 on the small magnetic recording sheet 32 . or,
Part information identification data indicating the part group "duodenum" selected by the button 21 of the camera unit 20 is similarly recorded on this image trunk 34 by the recording/reproducing device 30. The image data recorded through the first reading head 35 placed in contact with the image track 34 (during reproduction) is converted into an electrical signal (image information signal).

This image information signal is amplified by the full amplifier 41 to a predetermined level. Furthermore, the part data recorded on this track 34 is also converted into an electrical signal (part information signal), and this part information signal (=identification data) is amplified at a predetermined level 1. The region information signal amplified in this way is interpreted by the region reading circuit 42 and supplied to the disk controller 43 as a control H (M number, which will be described later).Furthermore, this control signal is supplied to the head drive circuit 44, where it is is applied as a head drive control signal to the actuator 45A of the head section 45. As a result, the laser diode 45 of the head section 45
B-1: It is possible to control loading and reading operations.

Furthermore, since the aforementioned auxiliary (search) data is recorded on the cue track 36 of the magnetic sheet 32, this is reproduced as an auxiliary (search) data signal via the second read node 37. This auxiliary data signal is amplified to a predetermined level by an amplifier 41B and supplied to an ID discrimination circuit 46, which identifies all necessary auxiliary data (search) signals. The identified auxiliary data signal is supplied to one input terminal of the full mixer 47. Further, the image information signal obtained from the amplifier 41 is supplied to the other input terminal. These signals are sent to the mixer 4
7 and supplied to a modulator 48 as a modulation signal. This modulator 48 modulates a carrier signal from a carrier signal generator (not shown) using the above-mentioned modulation signal, and applies the entire output of this modulation signal to the laser diode 45B of the head section 45.

On the other hand, the actuator 45A of the do portion 45 has
Since the region information signals supplied via the disk controller 43 and head drive circuit 44 are applied, each information signal is optically recorded on the optical disk 52 in the following recording state. That is, first, in terms of time and space, patient data is recorded on a predetermined track 54 of the light 73 disk 52, and then the corresponding auxiliary data (search signal) and image information signal are combined and recorded on this track 54. distributed above. Therefore, even for the same patient, the component force is recorded on the optical disk 52 in advance according to the A·+i Jlai of the site. As a result, a plurality of small magnetic recording sheets 32 can be reproduced as described above, processed by the processing circuit 40, edited on the optical disk 52, and then recorded. E+4 is also ``kou'', for example.
The patient's image data related to the above is such that auxiliary data and patient identification data (search information +-i) are added to each image data pqu.

Next, the reproduction of the optical disc 52 in which the image information signal has been completely edited and optically recorded in this manner will be briefly described.

As mentioned above, on the track 54 of this optical disc 52, auxiliary data (search signals) and image (stomach) information of a plurality of patients are serially recorded, for example, regarding the region of the "stomach". Therefore, by first specifying the region and then searching for the search signal, the head section 45 can perform optical reading to obtain the desired image information signal.In this case, the reproduction circuit is known. Therefore, I will not explain it further.

Next, a modification of the d-equipment processing circuit 4.theta. will be explained with reference to the third thread. [Cylinder] For the sake of simplicity, only the configurations that are different from those shown in Fig. 2 are shown.

In this example, the entire feature is that image data and body part data are recorded independently on the optical disk.

First, the image data reproduced by the magnetic recording/reproducing device 30 with a small recording capacity is supplied to the modulator 82, and is
It is supplied to a part I/u separation circuit 84 composed of a noise filter. As mentioned above, this image data also contains a region signal from the camera section 20 and region selection switch 2, so the modulation signal modulated by the modulator 82 contains not only the image information signal component but also the region signal component. Signal components are also present and these are optically recorded in image data tracks (not shown) on optical disk 52. On the other hand, only the part signal is separated/extracted by the part signal separation circuit 84,
It is supplied to a disk controller 86 and a mixer 88.

The part signal supplied to the disk controller 86 controls the actuator (5A) of the head section 45 via the head drive circuit 44. On the other hand, the mixer 88 receives not only this part signal but also search data (ID). Since the discriminating signal) signals are supplied, these signals are mixed and supplied to a separate laser diode (not shown).

and tv Separate laser diodes are placed on a search track (not shown) different from the image data track mentioned above, so that this search signal is recorded on this track.

Next, to explain the operation during reproduction, desired search data is extracted from the search track by a control command device (not shown). Based on this data, image data is extracted from the corresponding image data whole image data track.

In this case, since the above-mentioned region signal is added to this image data, this functions as an address signal at the time of data access.

The present invention is not limited to the embodiments described above, and it will be easy for those skilled in the art to make various changes.

For example, transfer image data etc. to the original disk.

When recording, it is also possible to further superimpose arbitrary data from the arbitrary data generator 49, as shown by the dashed line in FIG. This arbitrary data includes, for example, a disease name, a doctor's comment, and the like.

〔Effect of the invention〕

As described in detail above, according to the present invention, by making full use of a medium that is extremely quick and easy to record and reproduce, information can be electronically edited by a doctor 71; It has the advantage of being recordable.

Furthermore, when recording on a medium with a large recording capacity, there is an advantage that auxiliary data such as identification data can be arbitrarily superimposed and recorded.
