Description

Technical Field

[0001] This invention relates to the field of contrast imaging technology, specifically to a contrast imaging device for cardiology. Background Technology

[0002] Cardiology contrast imaging involves enhancing the signal of the un-contrast image after it has passed through the body, and then scanning the enhanced image with a high-resolution camera. The digital information of the contrast image is subtracted from the digital information of the un-contrast image, and the difference is represented as different gray levels, forming a difference image on the monitor. Since the numerical values ​​of the bone and soft tissue images are the same in both images, they are eliminated during subtraction, leaving only the images of blood vessels containing contrast agent. The result is the elimination of structures other than the contrast vessels, highlighting the image of the contrasted organ. The image signal after subtraction is proportional to the thickness / density of the contrast agent and related to the absorption coefficients of the contrast agent and blood vessels, but independent of the background.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7 This invention provides a technical solution: a cardiac imaging device, comprising an imaging body 101 and an imaging bed 102. A C-frame 103 is mounted on the imaging body 101, with a collimator 104 and an image intensifier 105 respectively mounted at both ends of the C-frame 103. The imaging bed 102 is positioned between the collimator 104 and the image intensifier 105. A fixed frame 2 is fixed to one end of the C-frame 103, and a lifting plate 3 is slidably connected inside the fixed frame 2. A lifting assembly for raising and lowering the lifting plate 3 is mounted on the fixed frame 2. 4 and guide component 5 for guiding during lifting and lowering, the lower end of lifting plate 3 is connected to operation plate 7 via connecting plate 6, image intensifier 105 is located on one side of operation plate 7, operation plate 7 is provided with flip component 8 for flipping image intensifier 105 and push component 9 for pushing image intensifier 105 during flipping, bottom of image intensifier 105 is provided with dust removal component 10 for dust removal from mirror surface of image intensifier 105, and outer side of fixed frame 2 is provided with sealing component 13 for sealing image intensifier 105;

[0028] The flipping assembly 8 includes a mounting box 801 fixed to one side of the operation plate 7. A spline shaft 802 is slidably connected inside the mounting box 801. A spline sleeve 803 is slidably connected to the spline shaft 802. The spline sleeve 803 is slidably connected to the operation plate 7, and one end of the spline sleeve 803 is fixed to the outside of the image intensifier 105. A mounting motor 804 for driving the spline shaft 802 is mounted on the outside of the mounting box 801. After the test is completed, the spline shaft 802 is driven to rotate by the mounting motor 804. During the rotation of the spline shaft 802, the image intensifier 105 is driven to rotate through the transmission between the spline shaft 802 and the spline sleeve 803. Through the rotation of the image intensifier 105, the lower end of the image intensifier 105 is flipped to face upward.

[0029] After the cardiac imaging system completes the examination of the patient, the image intensifier 105 is flipped and sealed off by the flipping component 8 to reduce the chance of damage to the image intensifier 105. During the flipping process, the image intensifier 105 is shaken by the transmission, and the dust accumulated on the mirror surface of the image intensifier 105 is blown away to ensure the cleanliness of the mirror surface of the image intensifier 105 when used again, thereby improving the detection effect of the cardiac imaging system.

[0030] Preferably, the pushing component 9 includes a mounting ring 901 fixed to the outside of the spline sleeve 803. A fixing pin 902 is fixed to the side of the mounting ring 901 facing the operating plate 7. A plurality of first protrusions 903 for pushing against one end of the fixing pin 902 are fixed in a circular array on the outside of the operating plate 7. A reset component 15 for resetting after being pushed is provided on the spline sleeve 803. The reset component 15 includes a fixing ring 1501 fixed to the outside of the spline sleeve 803. A first spring 1502 is sleeved on the outside of the spline sleeve 803. The two ends of the first spring 1502 are respectively abutted against the inner wall of the mounting box 801 and the fixing ring 1501. As the spline sleeve 803 rotates, the mounting ring 901 rotates synchronously. During the rotation, one end of the fixing pin 902 abuts against each of the first protrusions 903 in sequence. Through the pushing action of the first protrusions 903 against the fixing pin 902, the spline sleeve 803 is driven to slide on the operating plate 7. During the sliding of the spline sleeve 803, the fixing ring 1501 compresses the first spring 1502 to generate elastic force. Through the elastic force of the first spring 1502, the spline sleeve 803 is pushed to reset after movement. Therefore, during the rotation of the spline sleeve 803, through the pushing action of each of the first protrusions 903 against one end of the fixing pin 902 and the reset action of the first spring 1502 on the spline sleeve 803 after movement, the spline sleeve 803 rotates and slides back and forth on the operating plate 7.

[0031] Preferably, the dust removal assembly 10 includes an annular cover 1001 fixed to the lower end of the image intensifier 105. An annular tube 1002 is installed inside the annular cover 1001. Multiple air outlet tubes 1003 are fixed in a communicating array on the annular tube 1002. One end of each air outlet tube 1003 is positioned facing the mirror surface of the image intensifier 105. An inflation assembly 11 for inflating the inside of the annular tube 1002 is provided on the annular cover 1001. Through the inflation assembly 11, external gas is drawn into the air inlet tube 1101 and, through compression, blown through the annular tube 1002 from one end of each air outlet tube 1003 toward the mirror surface of the image intensifier 105. Through the blowing action, the floating dust accumulated on the mirror surface of the image intensifier 105 is cleaned by blowing, ensuring the cleanliness of the mirror surface of the image intensifier 105 when used again, and improving the detection effect of the cardiology imaging system.

[0032] Preferably, the inflation assembly 11 includes an air inlet pipe 1101 fixed on the annular cover 1001. One end of the air inlet pipe 1101 is connected to the annular pipe 1002. Two one-way valves 1102 are fixed inside the air inlet pipe 1101. The conduction direction of the two one-way valves 1102 is from the outside to the inside of the air inlet pipe 1101. A fixing pipe 1103 is fixedly connected to the air inlet pipe 1101. A piston plate 1104 is slidably connected to the fixing pipe 1103. The operating plate 7 is provided with a function for adjusting the piston. The extrusion assembly 12 is pressed by the plate 1104; through the extrusion assembly 12, the drive rod 1201 and the piston plate 1104 reciprocate on the fixed tube 1103. Since the conduction direction of the two one-way valves 1102 is from the outside to the inside of the air inlet pipe 1101, through the reciprocating motion of the piston plate 1104, the external gas is drawn into the inside of the air inlet pipe 1101 and, through extrusion, blows air from one end of each air outlet pipe 1003 toward the mirror surface of the image intensifier 105 through the annular pipe 1002.

[0033] Preferably, the extrusion assembly 12 includes a transmission rod 1201 slidably connected to one end of the fixed tube 1103. One end of the transmission rod 1201 is fixed to the piston plate 1104. A plurality of second protrusions 1202 for pushing against one end of the transmission rod 1201 are fixed in a circular array on one side of the operation plate 7. A second spring 1203 is sleeved on the outside of the transmission rod 1201. The two ends of the second spring 1203 are respectively abutted against the piston plate 1104 and the inner wall of the fixed tube 1103. During the flipping process of the image intensifier 105, the transmission rod 1201 at one end of the fixed tube 1103 abuts against each of the second protrusions 1202 in sequence. Through the pushing action of the second protrusions 1202 against one end of the transmission rod 1201 and the restoring action of the second spring 1203 on the transmission rod 1201 after movement, the transmission rod 1201 and the piston plate 1104 are driven to reciprocate on the fixed tube 1103.

[0034] Preferably, the sealing assembly 13 includes a support plate 1301 fixed to one side of the fixing frame 2, a sealing plate 1302 disposed below the support plate 1301, and a connecting assembly 14 between the support plate 1301 and the sealing plate 1302. A rubber pad 1303 for sealing the lower end of the image intensifier 105 is disposed at the lower end of the sealing plate 1302. The connecting assembly 14 includes a plurality of first sleeves 1401 fixed to the upper end of the sealing plate 1302, a first slide rod 1402 slidably connected to each first sleeve 1401, one end of the first slide rod 1402 being fixed to the support plate 1301, and a third slide rod 1402 being sleeved on the outer side of each first sleeve 1401. Spring 1403; through the cooperation of lifting assembly 4 and guide assembly 5, drive image intensifier 105 to move upward. During the upward movement of image intensifier 105, the end of image intensifier 105 abuts against rubber pad 1303 on sealing plate 1302. During the abutment, sealing plate 1302 is pushed towards support plate 1301 and each third spring 1403 is deformed by force to generate elastic force. Through the elastic force of each third spring 1403, the rubber pad 1303 on sealing plate 1302 is pushed to keep abutting against the end of image intensifier 105, thus shielding and protecting image intensifier 105 when not in use.

[0035] Preferably, the lifting assembly 4 includes a threaded rod 401 rotatably connected to the fixed frame 2, with a threaded tube 402 threadedly engaged with the threaded rod 401. One end of the threaded tube 402 is fixed to the lifting plate 3. A drive motor 403 for driving the threaded rod 401 is installed at the upper end of the fixed frame 2. The guide assembly 5 includes multiple second slide rods 501 fixed inside the fixed frame 2, with a second sleeve 502 slidably connected to each second slide rod 501. One end of the second sleeve 502 is fixed to the upper end of the lifting plate 3. The drive motor 403 drives the threaded rod 401 to rotate. During the rotation of the threaded rod 401, the lifting plate 3 moves up and down under force through the mutual meshing transmission between the threaded rod 401 and the threaded tube 402, and the sliding guidance effect between the second sleeve 502 and the second slide rod 501.

[0036] Working principle: When the cardiology imaging system is used to examine a patient, the patient lies on the examination bed 102. After lying down, the lifting assembly 4 and the guide assembly 5 work together to drive the lifting plate 3 to descend inside the fixed frame 2. During the descent of the lifting plate 3, the connecting plate 6 drives the operating plate 7 to descend synchronously. During the descent of the operating plate 7, the image intensifier 105 is driven to descend by the connection of the various components on the flipping assembly 8. The descent of the image intensifier 105 adjusts the distance between the lower end of the image intensifier 105 and the patient's examination position.

[0037] After the test is completed, the spline shaft 802 is driven to rotate by the motor 804. During the rotation of the spline shaft 802, the image intensifier 105 is driven to rotate through the transmission between the spline shaft 802 and the spline sleeve 803. The rotation of the image intensifier 105 causes its lower end to flip upwards. During the rotation of the spline sleeve 803 and the image intensifier 105, the mounting ring 901 rotates synchronously with the spline sleeve 803. During the rotation of the mounting ring 901, one end of the fixing pin 902 sequentially engages with each of the first protrusions. The first protrusion 903 and the fixing pin 902 push against each other, driving the spline sleeve 803 to slide on the operating plate 7. During the sliding process of the spline sleeve 803, the fixing ring 1501 compresses the first spring 1502 to generate elastic force. The elastic force of the first spring 1502 pushes the spline sleeve 803 to return to its original position after movement. Therefore, during the rotation of the spline sleeve 803, the pushing action of each first protrusion 903 against one end of the fixing pin 902 and the return action of the first spring 1502 on the spline sleeve 803 after movement cause the spline sleeve 803 to rotate. Simultaneously, the image intensifier 105 is vibrated during the flipping process by reciprocating the spline sleeve 803 on the operation panel 7. This vibration facilitates the separation of dust accumulated on the lens of the image intensifier 105. During the flipping process of the image intensifier 105, the transmission rod 1201 at one end of the fixed tube 1103 sequentially abuts against each of the second protrusions 1202. The pushing action of the second protrusions 1202 against one end of the transmission rod 1201, and the reset action of the second spring 1203 on the transmission rod 1201 after movement, drive the transmission rod 1201 and... The piston plate 1104 reciprocates on the fixed tube 1103. Since the conduction direction of the two one-way valves 1102 is from the outside to the inside of the air inlet tube 1101, the reciprocating motion of the piston plate 1104 draws the external gas into the inside of the air inlet tube 1101 and, through compression, blows air from one end of each air outlet tube 1003 toward the mirror surface of the image intensifier 105 through the annular tube 1002. Through the blowing action, the floating dust accumulated on the mirror surface of the image intensifier 105 is cleaned by blowing air, ensuring the cleanliness of the mirror surface of the image intensifier 105 when it is used again, and improving the detection effect of the cardiology imaging system.

[0038] After the image intensifier 105 is flipped, the lifting assembly 4 and the guide assembly 5 work together to drive the image intensifier 105 to move upward. During the upward movement of the image intensifier 105, the end of the image intensifier 105 comes into contact with the rubber pad 1303 on the sealing plate 1302. During the contact, the sealing plate 1302 is pushed towards the support plate 1301 and each of the third springs 1403 is deformed by force to generate elastic force. Through the elastic force of each of the third springs 1403, the rubber pad 1303 on the sealing plate 1302 is pushed to keep it in contact with the end of the image intensifier 105, thus shielding and protecting the image intensifier 105 when it is not in use.
