Description

Technical Field

[0001] This invention relates to the field of medical imaging equipment technology, and more specifically to a medical image processing device. Background Technology

[0002] To better utilize the penetrating power of X-rays in the medical field, existing technologies have developed X-ray machines that use X-rays to observe lesions inside the human body. The imaging principle is as follows: First, an X-ray tube generates X-rays. After the X-rays pass through a filter to remove soft rays, they irradiate the object being examined. After passing through the object, the X-rays are filtered out by a grid before reaching a fluorescent plate. The fluorescent plate generates a fluorescent image after being irradiated by X-rays. At this time, the fluorescent image is visible light. After being focused by a lens, it is projected onto a CCD chip. The CCD chip converts the visible light image into an electrical signal, which is then displayed on a screen to obtain a digital image. However, the above-mentioned X-ray image processing device still has the following shortcomings.

[0003] First, the X-ray filters used in current technology include different types, so changing the filters often requires manual operation. In addition to being inconvenient, this process can easily expose workers to X-rays by accident, which can cause damage to their health over time. Furthermore, when filtering soft X-rays, the filters themselves can generate heat by absorbing these rays over a long period of time. This means that the filters themselves can easily generate high temperatures, which can affect the filtering performance of the filters for specific soft X-rays. Traditional X-ray image processing devices do not have a device that can effectively absorb the heat energy of the filters.

[0004] Secondly, existing X-ray image processing devices need to beam the generated X-rays, that is, to control the size of the area of ​​the X-rays being irradiated. Traditional beaming devices use lead plates as X-ray shields, but after prolonged exposure to X-rays, the surface of the lead plate will also generate high temperatures, which will affect the normal operation of some electrical components in the machine. The beaming structure of traditional X-ray image processing devices does not have the function of preventing high temperatures.

[0005] Therefore, there is a need to provide a medical image processing device to solve the above problems. Summary of the Invention

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention includes a filter assembly. When the device is operating, the X-ray tube generates X-rays that irradiate downwards. The X-rays pass through a window and are filtered by a filter placed on the left side of the turntable. The filtered X-rays then irradiate downwards through a light-transmitting port. The turntable can hold four different types of filters, with the filters at the front, back, and right sides positioned at the bottom of a storage box and covered. A first servo motor drives the turntable to rotate, controlling the movement of different types of filters above the left light-transmitting port for filtering X-rays. This method replaces the manual replacement of filters. The replaced filters... Prolonged exposure to X-rays generates heat. Due to the change in position, the material is stored at the bottom of the storage box. At this time, the barium sulfate suspension is pumped into the cavity of the storage box through the injection pipe. Under the action of liquid pressure, the telescopic sleeve is stretched downward, and the heat exchange plate contacts the filter at the corresponding position at the bottom. The heat on the filter is absorbed by the heat exchange plate and carried into the flowing barium sulfate suspension. After reaching a certain hydraulic pressure, it is discharged through the pressure valve and the drain pipe. Since the downward moving heat exchange plate enters the circular slots opened at the front, back and right sides of the turntable, it also provides a certain limiting effect on the turntable.

[0016] 2. This invention includes a beam-beaming assembly. The second servo motor drives the drive linkage, and through the meshing transmission of the left and right gears, the left and right baffles on both sides can block the light-transmitting port to different degrees, thereby achieving beam-beaming of the X-rays irradiated at the light-transmitting port. The blocked parts of the left and right baffles generate heat energy due to the irradiation of X-rays. At this time, barium sulfate suspension is pumped into the internal cavities of the left and right baffles through the inlet pipe and the injection connecting pipe, respectively. Because the barium sulfate suspension has X-ray... The barium sulfate suspension has the ability to absorb X-rays, thus improving the X-ray shielding effect of the left and right shielding plates. The barium sulfate suspension will be discharged from the left and right corrugated telescopic drain pipes on both sides, and discharged from the outlet pipe through the drain connecting pipe. The flowing barium sulfate suspension will carry away the heat generated on the left and right shielding plates, thereby achieving a cooling effect on the left and right shielding plates. Moreover, the barium sulfate suspension filling the cavities of the left and right shielding plates will enhance their X-ray shielding effect. Attached Figure Description

[0030] In this embodiment, the X-ray tube 1 generates X-rays and irradiates downwards.

[0037] The working principle and beneficial effects of this invention are as follows: When the device is working, the X-ray tube 1 generates X-rays and irradiates downwards. The X-rays pass through the window 201 and are filtered by the filter 209 placed on the left side of the turntable 208. The filtered X-rays then irradiate downwards through the light-transmitting port 204. Four different types of filter 209 can be placed on the turntable 208, while the filter 209s on its front, back, and right sides are located at the bottom of the storage box 211 and covered. By driving the turntable 208 to rotate via the first servo motor 207, the different types of filter 209 can be moved to the top of the left light-transmitting port 204 to filter X-rays. This method replaces the manual replacement of the filter 209. The replaced filter 209 is then... Prolonged exposure to X-rays generates heat. Due to the change in position, the solution is stored at the bottom of the storage box 211. At this time, the barium sulfate suspension is pumped into the cavity of the storage box 211 through the injection pipe 216. Under the pressure of the liquid, the telescopic sleeve 212 extends downwards, bringing the heat exchange plate 213 into contact with the corresponding filter 209 at the bottom. The heat on the filter 209 is absorbed by the heat exchange plate 213 and carried into the flowing barium sulfate suspension. After reaching a certain hydraulic pressure, the solution is discharged through the pressure valve 218 and the drain pipe 217. Since the downward-moving heat exchange plate 213 enters the circular slots at the front, back, and right side of the turntable 208, it also provides a certain limiting effect on the turntable 208. The second servo motor... Driven by linkage 304, the left gear 307 and right gear 310 engage to transmit power, causing the left and right shielding plates 302 and 303 to block the light-transmitting port 204 to varying degrees. This achieves beaming of X-rays irradiated through the port 204. The shielding portions of the left and right shielding plates 302 and 303 generate heat due to X-ray irradiation. At this time, barium sulfate suspension is pumped into the internal cavities of the left and right shielding plates 302 and 303 respectively through the inlet pipe 316 and the injection connecting pipe 315. Because barium sulfate suspension has X-ray absorption capabilities, it enhances the X-ray shielding effect of the shielding portions of the left and right shielding plates 302 and 303. The barium sulfate suspension is discharged from the left corrugated telescopic drain pipe 317 and the right corrugated telescopic drain pipe 318 on both sides, and then discharged from the outlet pipe 320 through the drain connecting pipe 319. The flowing barium sulfate suspension carries away the heat generated on the left shield 302 and the right shield 303, thereby achieving a cooling effect on the left shield 302 and the right shield 303. Moreover, the barium sulfate suspension filling the cavities of the left shield 302 and the right shield 303 will enhance their X-ray shielding effect. The first liquid pump 408 and the second liquid pump 409 inject barium sulfate suspension into the left shield 302, the right shield 303 and the storage box 211, respectively. Due to the two major characteristics of barium sulfate suspension, namely fluidity and X-ray absorption,Therefore, X-rays can be shielded and heat generated in the left baffle 302, right baffle 303, and storage box 211 can be removed. The returned barium sulfate suspension is reinjected into the storage tank 407 through the cooling tubes 401 and the outlet pipe 320. The cooling tubes 401 are evenly distributed on the base plate 402, and the airflow is enhanced by the blower 404, thereby accelerating the cooling rate of the liquid in the cooling tubes 401. The airflow is discharged from the exhaust grille 405. In this way, the barium sulfate suspension can be cooled quickly and further recycled.
