Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is applicable to medical applications, particularly for text input of biological phenomenon waveforms during imaging, digitized data thereof, imaging conditions, etc. This relates to a device that simultaneously imprints images on film.

[Conventional technology]

Conventional XvA 35mm continuous photography devices, etc., only have the ability to count up and display biological phenomenon data and the number of frames from the start point.

Therefore, there is a problem that sufficient information cannot be read from the imprinted photograph because it does not have the function of displaying the input numerically or displaying the setting conditions.

[Problem that the invention seeks to solve]

The present invention aims to solve the conventional problem of not being able to obtain sufficient information from photographs.
In addition to information on waveforms and numbering, the objective is to provide a device that can display digital data related to waveforms, character input from the keyboard, etc. on the CR7 screen, and also imprint such data on photographs. It is something to do.

[Means for solving problems]

The present invention provides a frame image that integrates electrocardiograms, biological phenomenon waveforms such as electrocardiograms, data obtained by converting the waveforms into three-digit decimal numbers, character data input from a keyboard, and cine pulses (X-ray continuous photographic shutter trigger signals). This allows four types of numbering data for number display to be recorded on an X-ray film at the same time as an X-ray image.

The following description will be made based on the embodiments shown in the drawings.

The drawing is a block diagram showing the configuration of the present invention, and the device includes an A/D converter (5) including a sweep trigger, a D/A
Conversion unit (12), address counter (18), CRT
(14), a character generator section based on ROM (25), a power supply section (38), and a high voltage generation section (39).

The input signal is amplified by the analog amplifiers (1+, +21) and then converted into an 8-pin binary code by the A/'D converter (5).The digitized signal is input by the write-side address counter (18). , are stored in sequence at the specified addresses.

When the read-side address counter (18) inputs a cine pulse, the signals in RAM+91 are read out in the order of the 1-channel waveform and the 9-character 2-channel waveform. It takes about 4 to 5 hours to read out the cine pulse, and after reading it, wait for the next cine pulse and repeat the same operation again.

The display screen is, for example, 500mm horizontally. It is composed of 250 vertical coordinate points, and the human waveform is displayed as sampled at the corresponding coordinate points.

The time axis sweep is independent of the CRT sweep and is determined by the conversion speed of the A/D converter (5). This speed is configured to be continuously variable from 1 to 10 seconds per screen.

The cine pulse, which is the shutter trigger signal for the X-ray series, is integrated by a numbering counter (30), and the signal provides an address input for the ROM (25).

Further, character data inputted by the keyboard (35) passes through the buffer (36) and becomes the address input of the same <ROM (25).

These character signals are converted into characters by a ROM (25) having a character generator function, and displayed on a CRT using brightness modulation.

Description of each block> The A/D converter (5) has a function of converting an input analog signal into a digital signal and transferring it to memory. C
Analog signals coming in from HI and CH2 are sent to the preamplifier +11. +21, selected by the multiplexer (3) and sample hold (4), converted into a digital signal by the A/D converter (5), and written to RAM +91.

This device (7) RAM (91 is composed of, for example, 8xl 024 bits, and the memory output is from the D/A converter (12)
is converted into analog data and extracted.

It is configured such that 10H data is stored at addresses 0 to 511 on RAM 91, and 2CH data is stored at addresses 512 to 1023.

Input data is taken into the latch (7) in synchronization with the AC signal, and is stored in RAM +91 when the signal (2) is low.

The read signal launches (1) at the timing of signal R3.
0) and through the selector (11), the D/A
It is input to a converter (12).

In addition to blanking, a CG signal is input to the selector (11), and during this period, read address counter output CAO~2 is selected and becomes input to the D/A converter (12).

Input signals MAO-9 to RA and M191 are address inputs, and read and write addresses are alternately input.

The D/A converter (12) converts the 8-bit digital signal into an analog signal, outputs it, and supplies the signal to the deflection amplifier (13).

The address counter (18) includes a clock signal generator, a read address counter, a write address counter,
It consists of a comparator and a multiplexer.

The clock signal ordering unit is a part that generates timing signals necessary for memory writing, and creates six timings from the 2.4Mflz original oscillation, decodes them, and outputs Wl,
π1. X and AS signals are output.

The cine pulse input is applied to the numbering counter (3o) through the interface section (29) and integrated. If this counter (3o) is reset using the number reset button on the panel before shooting the film, the value accumulated thereafter will represent the number of frames on the film.

The output data of the numbering counter (30) and the numerical data of the binary coded decimal encoder (17) are stored in the buffer (22).
), (31) are applied to the character bus CSO~3 to provide the address input for the ROM (25).

Data in the ROM is serially transferred using an AC signal as a clock, and is transferred to a CRT (1) through a luminance amplifier (27).
4) is added to the luminance axis.

When the shutter for continuous X-ray photography is activated and the cine pulse is input to this device, the CRT (14) lights up and displays biological phenomenon waveforms, waveform data, character data, and numbering data. The image displayed on the CRT screen passes through the optical system and is refocused onto the film. As a result, the above four pieces of data are simultaneously printed onto the film along with the X-ray fluoroscopic image, creating a single sheet of film. The intended purpose of having all the data on the film can be achieved.

The part on the right side of the block diagram is the CR7671 part used for printing onto film, and is equipped with a high pressure generating section (39).

〔Effect of the invention〕

As described above, according to the present invention, necessary data can be transferred to a CRT.
The Xta
Since it can also be imprinted on film, it has the effect that sufficient information can be read from the imprinted photograph.
