The X-ray detector is a core part of the X-ray imaging device that converts the invisible The quality of the final video is determined.

X-ray detectors are classified into analog and digital types depending on the detection method. The analog method uses film to detect X-rays and has the advantage of being cheaper than the digital method. The analog method has been widely used in various industrial fields, including the medical field, for over 100 years, but it has disadvantages such as limitations in the information that film captures, spatial constraints such as film storage, and the storage and acquisition of images can be separated, so the digital method has been used since the 2000s. method is rapidly being replaced.

The digital method converts the Radiography) detector. The CR detector is an intermediate step between analog and digital, and is a process of acquiring digital images using an image plate (IP), a plate coated with fluorescent material, and using a separate reader to detect X-rays absorbed and stored in the IP. must go through. Since CR detectors take about 5 to 10 minutes to obtain an image after shooting, their low efficiency in terms of productivity is also a disadvantage.

A DR detector is a detector that can acquire images by converting X-rays into electrical signals with just one detector without any separate image detection equipment. Depending on whether the It is divided into direct conversion method and indirect conversion method.

The direct conversion method has the advantage of being able to achieve high resolution by directly converting the

The indirect conversion method converts X-rays into visible light and then converts them into electrical signals using an optoelectronic panel or CMOS sensor. Depending on the components used, the indirect conversion method is divided into a method using a TFT (A-si) panel and a method using a CMOS wafer.

In the case of the CMOS Wafer method, the resolution is high, the image quality is excellent, and the shooting speed is fast at 240 frames per second, making it easy to create videos, so it is used in breast cancer diagnostic devices, PCB soldering condition inspection, etc., and the cost per area is high, making it suitable for small-area shooting, so it is suitable for dental use. Mainly used for x-rays.

FIG. 2 is a combined diagram of the display device 100 with an X-ray detection function in FIG. 1.

1 and 2, a display device (hereinafter referred to as display device) 100 with an X-ray detection function according to an embodiment of the present invention includes a panel assembly 130 and a housing 140 for storing the same, The panel assembly 130 is characterized in that it has a structure that allows storage and discharge from the housing 140. The panel assembly 130 is comprised of the

When the display device 100 is operated, the panel assembly 130 is taken out from within the housing 140, and when the operation of the display device 100 is terminated, the panel assembly 130 is stored back into the housing 140. You can. When stored in the housing 140, the panner assembly 130 is rolled into a roll shape and stored in the housing 140.

It may be configured to include a display panel 120. Accordingly, one side of the panel assembly 130 corresponds to the side to which X-rays are irradiated, and the opposite side corresponds to the display light-emitting side.

As a second embodiment, the panel assembly 130 may be configured to detect X-rays irradiated using only one of the two sides and output the detected X-rays. A detailed description of the second embodiment will be described later.

The display device 100 includes a panel assembly 130 that is flexibly configured to be rolled into a roll, a housing 140 that accommodates the panel assembly 130, and a variable frame that supports the edges of the discharged panel assembly 130. It may be configured to include (150). The panel assembly 130 may be configured to include both an X-ray detector 110 and a display panel 120.

The X-ray detector 110 has a function of detecting irradiated X-rays and outputting an electrical signal corresponding to the detected X-rays. And the display panel 120 has the function of displaying an X-ray image using electrical signals. The X-ray detector 110 and the display panel 120 are formed with similar areas to form each side of the panel assembly 130, and are made of a flexible material, so the panel assembly 130 can be rolled into a roll shape.

The variable frame 150 is stored in the housing 140 in a folded state when the panel assembly 130 is stored in the housing 140, and in an unfolded state when the panel assembly 130 is released outside the housing 140. It has the function of supporting the edge of the panel assembly 130.

Figure 3 is a configuration diagram of a panel assembly according to an embodiment of the present invention.

Referring to Figure 3, the components of the panel assembly 130 are depicted. The panel assembly 130 may be composed of multiple layers. The panel assembly 130 includes an X-ray detector 110 and a display panel 120 bonded together. According to the first embodiment, the X-ray irradiation surface of the X-ray detector 110 and the screen of the display panel 120 face opposite directions.

The X-ray detector 110 may be implemented using a semiconductor, for example, a semiconductor using an organic material, or a flexible material. The display panel 120 can be implemented using existing flexible materials and semiconductors.

The X-ray detector 110 may be configured to include a flexible cover 111, a scintillator 112, a pixel array 113, and a substrate 114.

The flexible cover 111 corresponds to the side on which X-rays are irradiated and is configured to cover the scintillator 112. The flexible cover 111 may be implemented with a bendable material, for example, a synthetic film.

The scintillator 112 is a fluorescent material and can be implemented using GaOxSy (Gadox), Gd2O2S (GOS), or cesium iodine (Csl). When used in an indirect manner, the scintillator 112 converts incident X-rays into visible light.

The X-ray detector 110 is also called a flat panel detector (FPD). The sensitive part of the FPD is the pixel array (113). The pixel array 113 is a rectangular or square area with an area ranging from a few centimeters in the case of dental X-ray imaging to up to tens of centimeters in the case of chest imaging.

The pixel array 113 contains thousands of pixels, and each pixel is a square with a side length of tens or hundreds of micrometers, depending on the required spatial resolution.

Each time an X-ray image is taken, the pixel array 113 is irradiated with radiation very briefly. The pixel collects this survey and stores it until it is read. Each pixel consists of a photodiode and a switch. Photodiodes are the basic building blocks that generate electric charges from impinging x-rays. Flat panel detectors (FPDs) can be implemented using direct or indirect conversion methods.

The switch, another element of the pixel, can be made of a thin-film transistor (TFT), a technology derived from the display industry. Switches can also be implemented with the recently developed indium gallium zinc oxide (IGZO), which offers better performance than TFTs, and IGZO is expected to become more commonly used in FPDs in the next few years.

The substrate 114 is electrically coupled to the pixel array 113. Substrate 114 may include control tracking and signal tracking grids. Each control trace is connected to the gate of every pixel switch in a row, and each signal trace is connected to every output node in a row. At each pixel, the input node of the switch is connected to a photodiode. Therefore, the photodiode can be connected to the signal trace through the switch.

When electricity is supplied to the gate control line, all switches are turned on and photodiodes in the pixel row are connected to signal tracking. This allows the charge from the impinging X-rays to flow to the readout node. As the switch is turned on one row at a time, the system reads all rows one by one. After this procedure, the FPD will read the entire pixel array. PixelArray is then ready to acquire another X-ray image.

To implement this readout system, two important integrated circuits (ICs) may be used in the substrate 114, namely, a readout IC (ROIC) and a gate driver IC.

Readout ICs are placed along one side of the pixel array, and for the largest FPDs, they can be placed on opposite sides to speed up the readout sequence. The input of the readout IC is the signal trace. Generally, a readout integrated circuit (ROIC) is a multi-channel device that supports 256 lines. Each channel has an analog front end to collect and amplify the charge on the read line. An integrated analog-to-digital converter (ADC) then generates a digital output corresponding to the energy emitted by the X-rays impinging on the pixel, ready to be processed by the computer.

The gate driver IC is arranged along a pixel array located at right angles to the pixel array where the ROIC is arranged. This IC drives the control lines and can therefore enable or disable all switches along each row of pixels. Because a relatively large voltage is required to turn on a TFT switch, the gate driver IC must be able to handle such high voltage. The gate driver must quickly transition between different voltage levels across the IC and beyond, and must produce a low-noise output that does not interfere with the operation of the ROIC.

The final image quality, and thus the accuracy of the medical diagnosis, may depend on several parameters of the FPD. The performance of ROIC and gate driver IC can affect most of these parameters. Therefore, it is important to select ICs that are specifically designed and manufactured for high performance. The most important performance parameters are:

Sensitivity of the detector to x-ray energy. This includes the quantum efficiency of the photodiode and, in the case of indirect conversion, the scintillator efficiency.

Spatial resolution, which depends on pixel size. This is also a challenge in ROIC and gate driver IC development because the channel must be designed small enough to match the required pitch.

For dynamic applications with high read times, especially frames per second (reading of the entire pixel matrix), the IC must be fast enough to handle these rates. The time it takes to convert a line during the read phase is called line time.

The more image noise there is, the less ability to discern details and the greater the amount of X-ray radiation the patient is exposed to in order to obtain a clear image. The noise added by the IC should be a very small fraction of the detector's inherent noise.

Power consumption, which affects not only electricity costs and the environment, but also battery size and cost, as well as the useful operating time of portable, battery-powered FPDs.

The disadvantages of amorphous silicon (a-Si) TFT are that it has a low electron movement speed and is vulnerable to noise such as afterimages, which reduces the accuracy of disease diagnosis. And there are limitations in surgical X-rays that require high-speed video recording.

Oxide TFT is a TFT made from IGZN, an oxide of indium (In), gallium (Ga), and zinc (Zn), and provides 100 times faster electron transfer speed, 10 times less noise, high-definition images, and high-speed video compared to existing TFTs. This makes it possible to use it as an optimal TFT for DXD in diagnostic and surgical situations.

A flexible material such as PEN (polyethylene naphthalene) or PET (polyethylene terephthalate) may be used as a material for the substrate.

According to the second embodiment, the display device 100 may be configured to detect X-rays irradiated using one side of the panel assembly 130 and display an X-ray image.

Among the flexible cover 111, scintillator 112, pixel array 113, and substrate 114 that constitute the X-ray detector 110, the flexible cover 111 and scintillator 112 may be made of a transparent material. And, although the pixel array 113 is not completely transparent, it can be configured to allow the display backlight to pass through by adjusting the arrangement of the pixels. And since a transparent display can be constructed using current technology, the flexible cover 111, scintillator 112, and pixel array 113 corresponding to the transparent layer constituting the X-ray detector 110 are placed on the front, and the transparent display is made. The panel 120 may be placed in the middle, and the substrate 114 may be placed at the rear. In this configuration, X-rays are detected through the scintillator 112 and the pixel array 113 placed on the front, the detected X-rays are converted into an X-ray image by the substrate 114 placed on the back, and the converted The image may be output to the side where the X-ray is detected through the display panel 120 disposed in the middle.

Figure 4 is an example of the housing in Figure 2 made transparent.

Depending on the folding and unfolding motion of the panel assembly 130, the variable shock absorber 159 changes length, absorbs vibration, and assists the unfolding and unfolding motion using elastic force.

In addition to the edge coupled to the variable frame 150, the remaining two edges, that is, the second end located at the center of the roll 133, are coupled to the bobbin 160, and the opposite first end is coupled to the base frame 132. Can be combined.

The second end of the panel assembly 130 may be designed not to be discharged from the inside of the housing 140. That is, the display device 100 may include a bobbin 160 around which the panel assembly 130 can be wound.

It can be configured as follows.

The housing 140 further includes a control board equipped with a battery, and the control board may be configured to be electrically connected to the X-ray detector 110 and the display panel 120 that constitute the panel assembly 130. Since the It can be placed on an interior wall.

Among the variable frames 150, the first variable frame 151 on the left has the function of fixing the left edge of the panel assembly 130 in a released state based on the base frame 132. In the same way, the second variable frame 155 on the right has the function of fixing the right edge of the panel assembly 130 in the released state based on the base frame 132.
