Description

Technical Field

[0001] The present invention relates to the technical field of radiological imaging, and in particular to a radiological imaging reading device and a radiological imaging reading method. Background Art

[0002] With the rapid development of my country's medical industry, radiology plays an increasingly important role in clinical diagnosis. As a key device for radiology diagnosis, the performance of the radiology image film reading device directly affects the accuracy of diagnosis and the work efficiency of doctors. During the use of traditional reading devices, due to the limitations of screen brightness, manual marking and other factors, it is easy to cause visual fatigue in doctors, affecting the reading effect. For example, in the radiology imaging diagnosis reading device disclosed in Publication No.: CN108732768B, when in use, a local magnification is performed by moving the bottom cover and the convex lens to improve the doctor's observation efficiency of the local radiology image film. However, only the local magnification is performed, and the screen brightness does not change, so that the local part of the radiology image film cannot be made clearer, and the magnified part cannot provide a more obvious prompt for the radiology image film. In addition, when the radiology image film is stored for a long time and observed many times, its edges and surfaces will produce slight curling, so that the radiology image film is partially unclear and cannot be observed.

[0013] A method for reading radiological images, which uses the above-mentioned device for reading radiological images, specifically includes the following steps: S1, start motor 1, screw 1 rotates and drives screw barrel 1 to slide upward along slide barrel 3, when screw barrel 1 drives the light box to slide to a position suitable for the user, turn off motor 1, fit the radiological image light sheet to the outer light board, and insert the light box and the top of the outer light board from bottom to top, then the clamp clamps the radiological image light sheet through spring 1, start the light source board, and the light source passes through the frosted plate to illuminate the side wall of the outer light board, so that the content of the radiological image light sheet is clear; S2, twist the knob forward, the two ends of the knob are respectively threadedly matched with slide barrel 1 and rubber pressure barrel, so that slide barrel 1 slides toward the outer light board, the rubber pressure barrel is separated from the side wall of the outer light board, and after slide barrel 1 drives magnetic ring 1 to approach the outer light board, magnetic ring 1 attracts the magnetic ring through magnetic force. 2. Slide 2 follows magnetic ring 2 to slide toward the outer light board, and the high-transmittance film follows slide 2 to separate from the frosted board; S3. When the high-transmittance film separates from the frosted board, start motor 2, motor 3 and motor 4, and two screws 2 drive movable frame 1 and movable frame 2 to move synchronously longitudinally, and screws 3 and screw 4 drive sleeve 1 and sleeve 2 to move synchronously horizontally, so that the extension component and the focusing component adjust the brightening position. When the adjustment of the extension component and the focusing component is completed, motor 2, motor 3 and motor 4 are turned off, and the knob is twisted in the opposite direction to return slide 1 to its original position, and the magnetic force between magnetic ring 1 and magnetic ring 2 is eliminated. Slide 2 returns to its original position through spring 2, so that the high-transmittance film is tightly attached to the side wall of the frosted board to increase the brightness of the covered position. The rubber pressure cylinder moves toward the outer light board, and is squeezed and stretched through the side wall of the rubber pressure cylinder, so that the covered radiographic light sheet is spread flat on the side wall of the outer light board.

[0014] Compared with the prior art, the advantages of the present invention are: 1. The present invention cooperates between the high-transmittance film, the frosted plate and the focusing lens. When the doctor needs to locally brighten the radiographic image sheet being viewed, the magnetic ring one attracts the magnetic ring two through magnetic force, so that the slide tube two follows the magnetic ring two to move toward the outer light board. When the high-transmittance film moves away from the frosted plate, the position of the slide tube two is controlled by the forward and reverse rotation of the motor two and the motor four. When it moves to the required position, the slide tube two drives the high-transmittance film to move toward the frosted plate through the spring two, so that the high-transmittance film is tightly attached to the side wall of the frosted plate. Through the adhesion of the high-transmittance film and the frosted plate, the high-transmittance film can eliminate the diffuse reflection phenomenon of the frosted plate, so that the brightness of the light source is improved after passing through the focusing lens, and the brightness of the covered position is increased, so that the radiographic image sheet at the covered position is more obvious.

[0015] 2. The present invention cooperates between the rubber pressure cylinder and the rotating knob. When the doctor needs to locally brighten the radiographic image sheet being viewed, the rotating knob is twisted in the forward direction. The slide cylinder 1 and the rubber pressure cylinder are respectively threadedly matched with the two ends of the rotating knob, so that the slide cylinder 1 and the rubber pressure cylinder move relative to each other. The rubber pressure cylinder moves away from the outer light panel. When the rubber pressure cylinder moves to the required position following the slide sleeve 1, the rotating knob is twisted in the reverse direction. The rubber pressure cylinder contacts and squeezes the radiographic image sheet. The end of the rubber pressure cylinder expands outward and stretches the covered radiographic image sheet, so that the covered radiographic image sheet is laid flat on the side wall of the outer light panel, thereby eliminating the slight curling at the edge and surface of the radiographic image sheet and improving the doctor's observation efficiency of the radiographic image sheet.

[0016] 3. The present invention cooperates between the magnetic sheet and the magnetic rod. During the movement of the magnetic ring, the magnetic sheet attracts the magnetic rod through magnetic force, so that the magnetic rod moves along the slide groove with the magnetic sheet. When the magnetic rod moves to the locking groove, the magnetic rod is locked. During the movement of the magnetic rod, the magnetic rod pulls the rubber on both sides to shrink the rubber pressure cylinder. When the knob is twisted in the opposite direction, the slide cylinder drives the magnetic ring to return to its place, and the rubber pressure cylinder contacts and squeezes the radiographic image sheet, so that the magnetic rod is unlocked and moves to the end of the slide groove. The contraction of the rubber pressure cylinder by the magnetic rod can effectively improve the effect of the rubber pressure cylinder on stretching the radiographic image sheet and the service life of the rubber pressure cylinder.

[0017] 4. The present invention cooperates between the lens holder and the vacuum pump. When the slide cylinder 2 follows the magnetic ring 2 to move toward the outer light board, the lens holder drives the focusing lens to slide inside the slide cylinder 2, and starts the vacuum pump. The focusing lens squeezes the space between the high-transmittance film and the high-transmittance film, so that the high-transmittance film is convex. When the slide cylinder 2 drives the high-transmittance film to move toward the frosted plate through the spring 2, the high-transmittance film contacts and squeezes the frosted plate. The vacuum pump draws air between the high-transmittance film and the frosted plate through the air pipe, so that the high-transmittance film and the frosted plate fit more closely. The squeezing of the focusing lens and the exhaust of the vacuum pump can effectively improve the fit between the high-transmittance film and the frosted plate, thereby increasing the brightening effect of the covered position.
