Abstract

PURPOSE:To make unnecessary a trouble to stick a bar code, and to simplify a hardware constitution by making the code into a 'CALRA' code or a block code instead of the bar code. CONSTITUTION:The data such as a patient ID number, etc., inputted by a keyboard 1 are converted into the 'CALRA' code or the block code by a converter 2, transferred to a controller 5, and the controller 5 displays it on a liquid crystal display part 3 according to the 'CALRA' code. Here, when the photographing of an X-ray film is completed in a fast photographing part 12, light is generated from a light source 4, the code on the liquid crystal display plate 3 is regulated to a size conforming to the size of an optical fiber light receiving part 7 by an optical system 6, and an image is obtained on a surface. Further, the image is transmitted through an optical fiber 9 to an optical fiber light receiving part 10 in the fast photographing part 12 in an original film, the code is photographed on a film 11 surface, and the film with the written 'CALRA' code is obtained. Thus, the hardware constitution can be simplified, and the trouble to stick a bar code seal can be eliminated.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the digitization of X-ray film, and in particular to the digitization of
The present invention relates to an X-ray film digitizing device suitable for reading and writing information.

[Conventional technology]

Conventionally, a bar code shown in FIG. 4(a) has been used to add ID information when digitizing X-ray film. This is done by outputting the ID number in the ID information as a barcode using a barcode printer, and printing the sticker manually on the X-star film KIII! i#), and its readout was performed using a dedicated barcode league, and ID information other than the number (name, date, etc.) was stored together with the image data.

[Problem to be solved by the invention]

The above conventional technology does not take into consideration the accuracy of the barcode in the X direction shown in FIG. In order to receive this information, these are printed out using a special barcode printer, and then manually pasted onto the film one by one (it must be read using a code league). There was also the problem that it was time-consuming.

The purpose of the present invention is to eliminate the trouble of pasting barcodes;
Moreover, the purpose is to simplify the hardware configuration.

[Means to solve the problem]

The above object can be achieved by replacing the bar code with a Carla code as shown in FIG. 4(b) or a blocked code as shown in FIG. 4(C). In other words, unlike barcodes, Carla codes and blocked codes determine the 0N10FF state of bits based on the brightness and darkness of each block, so they do not require as much precision as barcodes in the X direction as well. Therefore,
The ID number is not affected by the MTF of the device when writing or reading it on the film, so it can be written directly onto the X-ray film without using a special device such as a barcode printer or barcode league. It is possible to read the image data in the same way as image data.

[Effect]

Carla code and blocked code are
D information is written directly onto the X-ray film at a certain position by the information writing device. This eliminates variations in the positions of the Carla codes and blocked codes on the film and saves time and effort.

Furthermore, since reading can be done by determining whether the bit is ON10 F F based on the brightness or darkness within the area where the code is located, it is possible to read an accurate ID number even if the film is slightly misaligned in both the X and Y directions. can.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a block diagram of an apparatus for writing Carla codes and blocking codes onto film. 1 is a keyboard for inputting external information, 2 is a converter that converts numerical data such as a patient ID number into a Carla code or a blocked code, 3 is a liquid crystal display board that displays the converted code, 4 is a light source, and 5 is a liquid crystal display 0N10FF't-controller for the board and light source; 6 is an optical system lens for making the code on the liquid crystal display board an appropriate size; 7 is an optical fiber bundle for reading the image onto the imaging plane; 8 numeral 9 is an optical fiber receiver, and numeral 10 is an optical fiber receiver, where the sent code is written on the film. Reference numeral 11 represents an X-ray film, and 12 represents a snapshot photographing section.

Next, the operation will be explained. In FIG. 1, data such as a patient ID number inputted on a keyboard is converted into a Carla code or a blocked code by a converter 2, and then transferred to a controller 5. The controller 5 displays the Carla code on the liquid crystal display board 3 according to the code. When the quick-shooting section 12 finishes photographing one piece of X-ray film, the light source 4
An artificial light is generated and the cord on the liquid crystal display panel 3 is passed through the optical system 6 and adjusted to a size that matches the size of the optical fiber light receiving section 7 to form an image on the surface. This image is then transferred to the optical fiber 9.
The code is transmitted as it is to the optical fiber light-receiving section 10 in the quick-shooting section 12 via the camera, and the code is imprinted onto the surface of the film 11 to obtain a film with the Carla code written thereon as shown in FIG.

Furthermore, if the information to be imported is only numerical data such as an ID number, it is also possible to use a block code as shown in FIG. 4(C). The blocking code is 1 block as 1
0N10F of 1 bit
Ft - Represents the brightness of the block. Therefore, 4 blocks = 4 bits can represent values from 0 to 15, and 27 blocks can represent a 9-digit ID number.

Next, the reading operation when digitizing the X-ray film photographed by the above method will be explained using the block diagram of FIG. 13 is a reading optical system, 14 is a laser tube,
15 is a vibrating mirror for scanning the laser onto the film; 16 is the photographed film shown in FIG. 2; 17 is a cylindrical mirror for condensing the transmitted laser light; 18 is a detector for reading the laser light; 19 is a A code detection unit extracts the Carla code area from the read image data and distinguishes it from the image data; 20 is the read image data and ID;
An external storage device 21 stores information, etc., which converts the read Carla code into numerical data and stores the corresponding I from the external storage device.
23 is an input device for offline inputting ID information into an external storage device such as a floppy disk or optical disk; 24 is an input device for online inputting ID information; 22 is C for displaying ID information, etc.
It is RT. Next, the operation will be explained. The laser light emitted from the laser tube 14 is scanned on the X-ray film 16 by the vibrating mirror 15, and the transmitted light is focused on the detector 18 by the F cylindrical mirror 17. From the data focused on the detector 18, the code detection unit 19 detects code data corresponding to the area of the Carla code determined at a certain position, and sends it to the converter 21.Other image data is sent to the external storage device 21. Forward. Also, at this time, the position of the Carla cord is 3rd.
As shown in the figure, the position is not set at the upper left of the film, but the position is determined when the system is installed, and from then on, writing and reading are performed at the determined position.

Next, depending on the brightness and darkness of each block of the Carla code input to the converter 21, one pit is ON10.
FF is determined and converted into numerical data.

Furthermore, the converted numerical data (ID number) is searched against the previously input IDi # information table, select all the relevant ID information, and enter the ID number number 1, 1, 1, and 1 'J. It is possible to store the included ID information together with the image data in an external storage device or to display it on a CRT.

〔Effect of the invention〕

According to the present invention, ID information can be set without using dedicated equipment such as a barcode printer or a barcode reader, and the hardware configuration can be simplified. Furthermore, there is no need for a person to affix a barcode sticker, which saves time and effort.
