Description

[0001] The present application mainly relates to the technical field of medical image fusion, and particularly relates to a system for fusing a patient's body surface feature photo and a medical image. BACKGROUND

[0002] With the rapid development of precision medicine and digital medicine, the demand for multi-modal information fusion in clinical diagnosis and treatment is increasingly urgent. The corresponding relationship between visible features on the body surface and CT, MRI and other medical images is a key basis for developing surgical plans, evaluating efficacy and follow-up observation. However, body surface information is usually obtained by ordinary cameras in an open environment, while image information is collected by special equipment in a shielded room. The two are naturally separated in spatial coordinates, time sequence and data format, which brings additional cognitive and operational burden to doctors.

[0003] The prior art generally adopts manual attachment of metal markers or pasting of color paper before image scanning, and then a technician compares the photo and the image according to memory or secondary measurement. This method highly depends on manual experience, the markers are easy to shift, and the secondary positioning error is often centimeter-level; at the same time, the photographing and scanning are performed separately, and the change of the patient's body position leads to a decrease in fusion accuracy. Some research institutions try to perform late registration through software algorithms, but the automatic registration success rate is low due to the large difference between the body surface contour and the image grayscale, and a large amount of manual correction is still needed, which is a cumbersome and time-consuming process.

[0004] In the prior art, the patient's affected area photo marking is complex and inconvenient for directly feeding back the patient's affected area abnormality level through the marking. SUMMARY

[0026] The control center packages and pushes the labeled body surface photos and corresponding DICOM images to the doctor's client and the patient's client; the doctor's client can view the "pain point-image" comparison map in real time, and the patient's client can also intuitively understand the location of the lesion, reducing the cost of doctor-patient communication;

[0027] The towel changing device adopts an active roller plus a driven roller structure. After the inspection is completed, the motor automatically rolls away the contaminated towel, and the new towel on the driven roller unfolds simultaneously. The whole process is closed to avoid cross-contamination. Attached Figure Description

The photograph capture module includes an examination bed 10, a positioning component 11 located on one side of the bottom of the examination bed 10 and extending to the upper part of the examination bed 10, and a shooting marker device 20 located at the execution end of the positioning component 11. The positioning component 11 includes an L-shaped moving rod 111 slidably connected to one side of the top of the examination bed 10, a first linear module 112 located at the bottom of the examination bed 10 for driving the L-shaped moving rod 111 to move, a second linear module 113 located at the top of the L-shaped moving rod 111, and a first electric cylinder 114 located at the execution end of the second linear module 113. The control center includes a photograph acquisition module, a medical camera-assisted positioning module, a medical image acquisition module, and a data feedback module. The photograph acquisition module includes a positioning unit, a marking unit, a shooting unit, and a cleaning unit.

[0042] It should be noted that, in this embodiment, the patient's affected area can be photographed by the photo-taking module before medical imaging. During the shooting process, the photo-taking module can mark and take pictures according to the patient's specified location of the affected area and description of sensation, so as to obtain the patient's affected area photo information.

[0043] The medical camera-assisted positioning module can trigger the medical imaging module based on the patient's affected area photo information to determine the shooting position corresponding to the photo information. The medical image acquisition module acquires the medical image information of the patient's affected area captured by the medical imaging module. The data feedback module feeds back the patient's affected area photo information and the patient's affected area medical image information to the doctor's client and the patient's client so that the doctor can compare and diagnose. The doctor can quickly understand the patient's pain points through the patient's affected area photo information with markings. At the same time, combined with the affected area medical image information, it is convenient to make a quick diagnosis. The doctor can also view the patient's affected area photo and affected area medical image information by fusion.

[0044] Furthermore, an audio recording device can be installed on the examination bed 10. After the control center receives the patient's lesion description information uploaded by the audio recording device, it triggers the first drive component 26 to rotate the marker 25 to the corresponding marker color.

[0045] Furthermore, when the photo-taking module takes a photo, the cleaning unit triggers the drape-changing device 30 to change the drape, and the patient can lie on the examination bed 10. The positioning unit triggers the positioning component 11 to perform positioning work to position the shooting marking device 20 to the shooting position. The marking unit triggers the shooting marking device 20 to perform marking work, and the shooting unit triggers the camera component 21 to take a photo.

[0046] Furthermore, when the positioning component 11 is working, the first linear module 112 actuator drives the L-shaped moving rod 111 to move, the second linear module 113 actuator drives the first electric cylinder 114 to move, and the first electric cylinder 114 drives the shooting marking device 20 to rise and fall.

Component 27 is used to drive the telescopic component 24 to extend and retract. The magnetic lifting component 22 includes a positioning groove 221 embedded in the top of the base ring 202, an electromagnetic block 222 disposed at the bottom of the positioning groove 221, and a magnetic block 223 disposed at the bottom of the lifting plate 23. The telescopic component 24 includes an outer sleeve 241 disposed at the top of the lifting plate 23, and a telescopic tube 242 passing through the outer sleeve 241 and slidably connected to the outer sleeve 241. The marker 25 includes a turntable 251 rotatably connected to the end of the telescopic tube 242, a square marking rod 252 disposed on the outer wall of the turntable 251, and a plurality of colored paper pasting slots 253 embedded in the outer wall of the square marking rod 252 and arranged in a circular array. The first drive The moving component 26 includes a first rotating ring 261 rotatably connected to the bottom of the outer cover ring 201, a first drive motor 262 disposed at the top of the outer cover ring 201 with its actuating end penetrating through the outer cover ring 201, a first drive disk 263 disposed at the actuating end of the first drive motor 262 with its outer wall abutting against the outer wall of the first rotating ring 261, and a friction ring 264 disposed on the outer wall of the rotating disk 261; the friction ring 264 corresponds to the position of the first rotating ring 261. The second driving component 27 includes a second rotating ring 271 rotatably connected to the bottom of the outer cover ring 201, a second drive motor 272 disposed at the top of the outer cover ring 201 with its actuating end penetrating through the outer cover ring 201, and a first drive disk 263 disposed at the actuating end of the second drive motor 262 with its outer wall abutting against the outer wall of the first rotating ring 261. The second drive disc 273 on the outer wall of the second rotating ring 271 has a lead screw 274 rotatably connected to the upper surface of the lifting plate 23 at one end via a bearing seat and extending into the telescopic tube 242 at the other end, and a friction disc 275 sleeved on the outer wall of the lead screw 274; the lead screw 274 is connected to the lead screw nut of the telescopic tube 242, and the friction disc 275 corresponds to the position of the second rotating ring 271. The camera component 21 includes a horizontal plate 211 disposed at the execution end of the first electric cylinder 114, a camera 212 disposed at the bottom of the horizontal plate 211, two second electric cylinders 213 symmetrically disposed at the top two ends of the horizontal plate 211 and whose execution ends penetrate the horizontal plate 211, and an annular cover 214 disposed at the execution end of the second electric cylinder 213.The bottom of the annular cover 214 is connected to the top of the outer cover ring 201.

[0048] It should be noted that, in this embodiment, when the marking device 20 is working, the camera component 21 captures the image information of the patient's finger pointing to the affected area and transmits it to the control center. The control center first triggers the corresponding magnetic lifting component 22 to work, so that the lifting plate 23 moves upward. The control center then triggers the first driving component 26 to rotate the marker 25 to the corresponding marking color. Finally, the control center triggers the second driving component 27 to make the telescopic component 24 drive the marker 25 to move to the designated position to complete the marking specified by the patient once. The patient can make multiple markings.

[0049] Furthermore, when the camera component 21 is working, the actuator of the second electric cylinder 213 can drive the annular cover 214 to rise and fall, so as to change the proportion of the marker 25 in the picture by physical means, and at the same time change the proportion of the base ring 202 in the picture, so that the camera 212 can take pictures of the patient's affected area.

[0050] Furthermore, when the magnetic lifting component 22 is working, the electromagnetic block 222 is energized to generate a repulsive force that is the same as that of the magnetic block 223. The repulsive force pushes the lifting plate 23 upward. Conversely, when the electromagnetic block 222 is energized, it generates an attractive force that is opposite to that of the magnetic block 223. The attractive force pushes the lifting plate 23 downward.

[0051] Furthermore, when the first drive component 26 is working, the first drive motor 262 drives the first rotating ring 261 to rotate through the first drive disk 263, and the first rotating ring 261 can drive the rotating disk 251 to rotate through the friction ring 264, so that the square marker rod 252 rotates.

[0052] After the lifting plate 23 moves upward, the outer wall of the friction ring 264 can abut against the outer wall of the first rotating ring 261;

[0053] The square marking rod 252 has multiple colored paper pasting slots 253 on its outer wall, which can be used to paste colored paper of different colors. Colored paper marking is cheaper and more stable than electronic marking.

[0054] Furthermore, when the second drive component 27 is working, the execution end of the second drive motor 272 can drive the second rotating ring 271 to rotate through the second drive disk 273, and the second rotating ring 271 can drive the lead screw 274 to rotate through the friction disk 275, and the lead screw 274 can drive the telescopic tube 242 to slide along the outer sleeve 241.

[0055] After the lifting plate 23 moves upward, the outer wall of the friction disc 275 can abut against the outer wall of the second rotating ring 271.

[0056] Please refer to the appendix in this embodiment. Figure 2 , 10As shown, in a preferred embodiment of the present invention, a towel changing device 30 is further provided at the bottom of the examination bed 10. The towel changing device 30 includes two positioning boxes 31 symmetrically provided at the bottom of the examination bed 10, a driven roller 32 provided in one of the positioning boxes 31, and a driving roller 33 provided in the other positioning box 31. The driven roller 32 is used to hold disposable towel rolls.

[0057] It should be noted that in this embodiment, the disposable quilt roll is placed outside the driven roller 32. The quilt end of the disposable quilt roll passes through the positioning box 31 corresponding to the driven roller 32, the top of the inspection bed 10, and the positioning box 31 corresponding to the active roller 33, and is then attached to the active roller 33. The motor drives the active roller 33 to rotate, so that the disposable quilt on the top of the inspection bed 10 can be replaced.

[0058] The working principle of this invention is as follows:

[0059] Before medical imaging, the patient's affected area can be photographed through the photo-taking module. During the imaging process, the photo-taking module can mark and take pictures according to the patient's specified location of the affected area and description of sensation, so as to obtain the patient's affected area photo information.

[0060] The medical camera-assisted positioning module can trigger the medical imaging module based on the patient's affected area photo information to determine the shooting position corresponding to the photo information. The medical image acquisition module acquires the medical image information of the patient's affected area captured by the medical imaging module. The data feedback module feeds back the patient's affected area photo information and the patient's affected area medical image information to the doctor's client and the patient's client so that the doctor can compare and diagnose. The doctor can quickly understand the patient's pain points through the patient's affected area photo information with markings. At the same time, combined with the affected area medical image information, it is convenient to make a quick diagnosis. The doctor can also view the patient's affected area photo and affected area medical image information by fusion.

[0061] A sound recording device can be installed on the examination bed 10. After the control center receives the patient's lesion description information uploaded by the sound recording device, it triggers the first drive component 26 to rotate the marker 25 to the corresponding marker color, such as red indicating the highest pain level.

[0062] When the photo-taking module takes a photo, the cleaning unit triggers the drape-changing device 30 to change the drape, and the patient can lie on the examination bed 10. The positioning unit triggers the positioning component 11 to perform positioning work to position the shooting marking device 20 to the shooting position. The marking unit triggers the shooting marking device 20 to perform marking work, and the shooting unit triggers the camera component 21 to take a photo.

[0063] When the positioning component 11 is working, the first linear module 112 actuator drives the L-shaped moving rod 111 to move, the second linear module 113 actuator drives the first electric cylinder 114 to move, and the first electric cylinder 114 drives the shooting marking device 20 to rise and fall.

[0064] When the marking device 20 is working, the camera component 21 captures an image of the patient pointing to the affected area and transmits it to the control center. The control center first triggers the corresponding magnetic lifting component 22 to move the lifting plate 23 upward. The control center then triggers the first drive component 26 to rotate the marker 25 to the corresponding marking color. Finally, the control center triggers the second drive component 27 to move the marker 25 to the designated position via the actuator of the telescopic component 24, thus completing one marking specified by the patient. The patient can make multiple markings.

[0065] When the camera component 21 is working, the actuator of the second electric cylinder 213 can drive the annular cover 214 to rise and fall, so as to change the proportion of the marker 25 in the picture through physical means, and at the same time change the proportion of the base ring 202 in the picture, and the camera 212 can take pictures of the patient's affected area.

[0066] When the magnetic lifting component 22 is working, the electromagnetic block 222 is energized and generates a repulsive force that is the same as that of the magnetic block 223. The repulsive force pushes the lifting plate 23 to move upward. Conversely, when the electromagnetic block 222 is energized, it generates an attractive force that is opposite to that of the magnetic block 223. The attractive force pushes the lifting plate 23 to move downward.

[0067] When the first driving component 26 is working, the first driving motor 262 drives the first rotating ring 261 to rotate through the first driving disk 263. The first rotating ring 261 can drive the rotating disk 251 to rotate through the friction ring 264, so that the square marker rod 252 rotates.

[0068] After the lifting plate 23 moves upward, the outer wall of the friction ring 264 can abut against the outer wall of the first rotating ring 261;

[0069] The square marking rod 252 has multiple colored paper pasting slots 253 on its outer wall, which can be used to paste colored paper of different colors. Colored paper marking is cheaper and more stable than electronic marking.

[0070] When the second drive component 27 is working, the second drive motor 272 can drive the second rotating ring 271 to rotate through the second drive disk 273. The second rotating ring 271 drives the lead screw 274 to rotate through the friction disk 275. The lead screw 274 drives the telescopic tube 242 to slide along the outer sleeve 241.

[0071] After the lifting plate 23 moves upward, the outer wall of the friction disc 275 can abut against the outer wall of the second rotating ring 271;

[0072] The disposable drape roll is placed over the driven roller 32. The drape end of the disposable drape roll passes through the positioning box 31 corresponding to the driven roller 32, the top of the inspection bed 10, and the positioning box 31 corresponding to the drive roller 33, and then adheres to the drive roller 33. The motor drives the drive roller 33 to rotate, so that the disposable drape on the top of the inspection bed 10 can be replaced.
