Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a quantum MRI device with fast intelligent scanning for detecting transformation of cerebral hemorrhage. Background Art

[0002] Cerebral hemorrhage is a cerebrovascular disease that poses a serious threat to human health, with extremely high mortality and disability rates. Cerebral hemorrhage transformation, that is, a series of changes in the bleeding site and surrounding tissues during the pathophysiological evolution after cerebral hemorrhage, such as hematoma expansion, surrounding tissue edema, and rebleeding, plays a decisive role in the patient's disease progression and prognosis. Timely and accurate detection of cerebral hemorrhage transformation is of irreplaceable importance for doctors to formulate scientific and reasonable treatment plans, such as whether to perform surgical intervention, adjust drug treatment strategies, etc., as well as to evaluate the patient's prognosis. For example, early detection of hematoma expansion enables doctors to take timely surgery to remove the hematoma, reduce intracranial pressure, and avoid further damage to brain tissue; accurately grasping the degree and range of surrounding tissue edema helps doctors to use dehydration drugs rationally, reduce brain edema, and protect neurological function.

[0003] However, traditional MRI technology has significant problems in the detection of cerebral hemorrhage transformation. Traditional MRI is based on the principle of classical electromagnetic signal acquisition and processing. The data acquisition and encoding speed is limited. When detecting cerebral hemorrhage transformation, it usually takes 30 minutes to 1 hour to obtain sufficient image information. In the acute cerebral hemorrhage transformation stage, the patient's condition is critical. Every second of delay may lead to worsening of the condition and miss the best time for treatment. Moreover, during the long-term detection process, it is difficult for patients to remain completely still due to physical discomfort, pain, etc. Slight movement will produce artifacts in the MRI image, interfering with the doctor's observation of the bleeding site and surrounding tissues, leading to misdiagnosis or missed diagnosis. Studies have shown that about 30%-50% of MRI images have artifact problems to varying degrees. In addition, patients with different body shapes and physiological conditions have different requirements for scanning parameters and fixation methods when undergoing MRI testing, but traditional detection methods cannot be effectively adjusted according to individual differences. Patients with larger bodies may require a larger scanning field of view and a stronger magnetic field strength, while patients with smaller bodies, too high magnetic field strength and too large scanning field of view will lead to reduced image quality. For patients with special diseases or physical conditions, such as those with pacemaker implants or metal fixtures in their bodies, traditional MRI detection methods face many challenges in ensuring detection safety and accuracy. The strong artifacts generated by metal objects in the MRI magnetic field seriously affect image quality and diagnostic results.

[0004] In summary, traditional MRI technology has problems in the detection of cerebral hemorrhage transformation, such as long detection time, image artifacts easily affected by patient movement, and lack of adaptive adjustment capabilities, which seriously restricts its clinical application effect. It is urgent to break through these bottlenecks and improve the efficiency and accuracy of cerebral hemorrhage transformation detection. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a fast scanning quantum MRI mechanical system, which is made of high-strength and low-permeability alloy and has superconducting quantum bit units engraved on the surface arranged in a specific coding matrix and connected to a non-magnetic aluminum alloy scanning coil bracket by a deep groove ball bearing, and driven by a high-torque and high-speed DC brushless motor through a driving gear, a driven gear and a high-strength rubber transmission belt embedded with steel wire to achieve precise speed regulation. A pressure sensor array composed of multiple miniature piezoresistive pressure sensors distributed on a polyimide flexible circuit board and connected to a control system signal acquisition module through a conductive line, an image recognition camera with high resolution and low illumination and installed on an adjustable aluminum alloy bracket and connected to a control system image acquisition module through a data line, a patient adaptive fixation device composed of a multi-joint structure consisting of a fixed base, a rotating joint, a telescopic arm and an adjustable chuck with an internally embedded flexible fixing pad, and a mechanical chuck arm driven by a motor to achieve precise control; and related mechanical transmission devices, electrical connections and control systems, etc., thereby solving the problems of the existing MRI technology in the detection of cerebral hemorrhage transformation, such as long detection time, image artifacts easily affected by patient movement, and lack of adaptive adjustment ability to adapt to patients with different body shapes and physiological conditions.

[0011] Furthermore, the transmission belt is made of high-strength, wear-resistant rubber material and is embedded with steel wires, and the length of the transmission belt is precisely customized according to the center distance between the driving gear and the driven gear.

[0012] Furthermore, the patient adaptive fixation device includes a pressure sensor array, an image recognition camera, a mechanical clamp arm and a flexible fixing pad. The pressure sensor array is composed of a plurality of miniature piezoresistive pressure sensors evenly distributed on a polyimide flexible circuit board. The flexible circuit board fits tightly into a pre-processed groove on the surface of the scanning bed and is flush with the bed surface. The pressure sensor is connected to the control system signal acquisition module via a thin copper wire conductive circuit.

The inner ring of the deep groove ball bearing 6 is tightly interference-fitted on the central axis 33, and the outer ring is tightly fitted with the mounting hole at the top center of the MRI scanning coil support 2, so that the quantum encoding disk 3 is located directly above the scanning coil support 2 and the central axes of the two coincide, ensuring that the quantum encoding disk 3 can rotate flexibly and stably.

[0042] (IV) Patient adaptive fixation device 4

[0043] The patient adaptive fixation device 4 includes a pressure sensor array 41 , an image recognition camera 42 , a mechanical clamping arm 43 and a flexible fixation pad 44 .

[0044] Pressure sensor array 41: It is composed of multiple 10mm×10mm miniature piezoresistive pressure sensors 411 evenly distributed on a polyimide flexible circuit board 412. The flexible circuit board 412 fits tightly into the groove pre-processed on the surface of the scanning bed 1 and is flush with the bed surface to ensure that the patient does not feel any foreign body when lying down. The pressure sensor 411 is connected to the control system signal acquisition module 5 through a thin copper wire conductive line. The wire width is 0.5mm, and the wiring is carefully designed to avoid signal interference.

[0045] Image recognition camera 42: It uses an industrial camera with a high resolution of 5 million pixels and a low illumination of 0.01 Lux, and is installed on the side of the scanning bed 1 through an aluminum alloy bracket. The rotating joint and knob adjustment mechanism on the aluminum alloy bracket can adjust the angle of the camera in the horizontal and vertical directions to fully and clearly capture the patient's body posture. The camera is connected to the control system signal acquisition module 5 through a high-speed, low-interference shielded data cable, and the length of the data cable is determined according to the actual installation location.

[0046] Mechanical clamp arm 43: It adopts a multi-joint structure, and the fixed base made of cast iron is vertically fixed to the side of the scanning bed 1 frame by M8 bolts. The rotary joint adopts a high-precision rotary bearing to achieve 360° rotation. The telescopic arm consists of an inner tube and an outer tube. The inner tube is connected to the outer tube through a linear guide rail, located inside the outer tube and can be extended and retracted along the guide rail. The motor is connected to the lead screw through a coupling, and the lead screw nut is installed on the inner tube and located inside the outer tube. The motor drives the lead screw nut mechanism to achieve the telescopic function. The chuck adopts an adjustable arc structure and is installed at the front end of the telescopic arm. A flexible fixed pad 44 is embedded inside. The ±30° angle adjustment is achieved through bolt connection and angle adjustment mechanism to adapt to the patient's body shape and position.

[0048] (V) Control system signal acquisition module 5

[0049] The control system signal acquisition module 5 includes a box 51, and a central controller 52 and a signal collector 53 are fixedly arranged inside the box 51.

The signal collector 53 is responsible for accurately collecting various sensor signals and converting them into digital signals that can be recognized and processed by the central controller 52. The box 51 is made of metal material and has good shielding performance, which can effectively prevent external electromagnetic interference and ensure the stable operation of the control system.

[0050] 2. Steps for using the device

[0051] (I) Equipment preparation

[0052] Check whether all parts of the equipment are complete and undamaged, and ensure that all connecting lines are not damaged or loose.

[0053] The scanning bed 1 is fixed according to the designed position and its levelness is adjusted to ensure the stability of the patient when lying down.

[0054] The MRI scanning coil bracket 2 is firmly installed on the upper end of the scanning bed 1 by bolts, ensuring that the bracket is firmly installed and accurately positioned, and the center of the bracket coincides with the central axis of the scanning bed 1, providing a stable foundation for the subsequent installation of the quantum encoder disk 3.

[0055] Heat the inner ring of the deep groove ball bearing 6 to 80-100°C, use the oil bath heating method to expand it, and then quickly put it on the central axis 33 of the quantum encoding disk 3, and form an interference fit after cooling and shrinking. Then align the central axis 33 of the quantum encoding disk 3 with the inner ring of the deep groove ball bearing 6 with the mounting hole on the scanning coil bracket 2, and slowly press the outer ring of the deep groove ball bearing 6 into the mounting hole to complete the installation of the quantum encoding disk 3 assembly, ensuring that the quantum encoding disk 3 can rotate flexibly and stably. Install the mechanical transmission device, fix the DC brushless drive motor 71 on the equipment frame through the motor mounting seat, and ensure that the motor output shaft is accurately aligned with the installation position of the driving gear 721. Connect the driving gear 721 to the output shaft of the DC brushless drive motor 71 through a key, and fix it with a nut or a locking device to prevent axial displacement. Install the driven gear 722 on the central axis 33 of the quantum encoding disk 3, and the installation method is the same as that of the driving gear 721. According to the center distance between the driving gear 721 and the driven gear 722, a transmission belt 73 of appropriate length is selected, which is wrapped around the two gears, and the tension is adjusted to ensure that the belt fits tightly with the gears and does not slip during the transmission process. The power line and control line of the DC brushless drive motor 71 are connected to the control system signal acquisition module 5 for preliminary debugging, and the speed adjustment function of the motor is tested to ensure that the quantum encoding disk 3 can rotate stably within the range of 5 rpm to 10 rpm.

[0056] Install the patient adaptive fixation device 4, evenly apply flexible glue in the groove pre-processed on the surface of the scanning bed 1, embed the pressure sensor array 41 into the groove, ensure that it is flush with the bed surface, and then connect the conductive line to the signal collector 53 of the control system signal acquisition module 5. Install the image recognition camera 42 on both sides of the scanning bed 1 through an aluminum alloy bracket, adjust the angle of the camera according to actual needs so that it can cover the entire scanning area, connect the data line to the signal collector 53 of the control system signal acquisition module 5, and calibrate the image clarity and recognition function. Fix the fixed base of the mechanical clamp arm 43 to the frame of the scanning bed 1 with M8 bolts, install the rotating joint, telescopic arm and clamp, and connect the motor control line to the control system signal acquisition module 5. Jointly debug the pressure sensor array 41, image recognition camera 42 and mechanical clamp arm 43 to ensure that each component can work together, accurately detect the patient's movement and adjust the fixed position in time. Check whether the connection between the central controller 52 and the signal collector 53 in the control system signal acquisition module 5 is correct, and perform system initialization settings, including calibrating the zero point of various sensors, setting the data acquisition frequency, etc.

[0057] (II) Intelligent scanning detection

[0058] The patient lies on the scanning bed 1, the pressure sensor array 41 monitors the contact pressure changes between the patient's body and the scanning bed 1 in real time, and the image recognition camera 42 takes real-time images of the patient's body posture. The pressure sensor 411 transmits the pressure data to the signal collector 53 of the control system signal acquisition module 5 through the conductive line, and the image recognition camera 42 transmits the captured image data to the signal collector 53 through the data line.

[0059] The central controller 52 of the control system signal acquisition module 5 receives and analyzes the data sent by the pressure sensor array 41 and the image recognition camera 42 to determine whether the patient has moved. If the patient moves, the central controller 52 calculates the parameters that need to be adjusted according to the preset algorithm and sends instructions to the motor of the mechanical clamp arm 43. The motor drives the lead screw nut mechanism to extend or shorten the telescopic arm, and the rotating joint drives the clamp arm to rotate, adjust the position and angle of the clamp head, and re-fix the patient's body with the flexible fixing pad 44, thereby realizing the intelligent and automated control device to limit and fix the patient.

[0060] While fixing the patient, the central controller issues a command to start the DC brushless drive motor 71, which drives the quantum encoding disk 3 to rotate at high speed through the mechanical transmission device to perform quantum encoding and scanning on the cerebral hemorrhage site. The DC brushless drive motor 71 outputs power, and drives the quantum encoding disk 3 to rotate at a set speed through the driving gear 721, the transmission belt 73 and the driven gear 722. The quantum encoding disk 3 uses the superposition state and quantum parallelism of quantum bits to quickly encode information at different levels and angles of the cerebral hemorrhage site.

[0061] The quantum encoder disk 3 transmits the encoded signal to the scanning coil (not shown, working in conjunction with the MRI scanning coil support 2), and the scanning coil collects data and transmits it to the control system signal acquisition module 5. The control system signal acquisition module 5 processes, analyzes and reconstructs the collected data to generate an MRI image. The central controller 52 performs pre-processing such as filtering and noise reduction on the data, and then reconstructs the data using complex algorithms to generate clear and accurate MRI images for doctors to perform diagnostic analysis, thereby realizing intelligent scanning analysis.

[0062] 3. Technical Effects of the Device

[0063] 1. Improving detection efficiency

[0064] The quantum encoding disk 3 uses the superposition state and quantum parallelism of quantum bits, and can process multiple data at the same time in one operation, greatly improving the encoding speed. Compared with the traditional MRI encoding method, its encoding speed has increased several times, thereby shortening the overall MRI scanning time. In actual tests, for complex cerebral hemorrhage cases, the traditional scanning method takes 30-60 minutes to complete the detection, while the fast scanning system of the present invention only takes 5-10 minutes, greatly improving the detection efficiency and gaining precious treatment time for critically ill cerebral hemorrhage patients.

[0065] The mechanical transmission device adopts a high-torque, high-speed DC brushless drive motor 71, with a reasonably designed gear ratio and a stable transmission belt 73, which can achieve precise speed adjustment of the quantum encoding disk 3 from 5 rpm to 10 rpm, ensuring stable and high-speed rotation of the quantum encoding disk 3, and further improving the scanning speed.

[0066] (II) Improving image quality

[0067] The patient adaptive fixation device 4 monitors the contact pressure changes between the patient's body and the scanning bed 1 in real time through the pressure sensor array 41, and the image recognition camera 42 takes the patient's body posture image in real time, which can detect the patient's movement in a timely and accurate manner. When the patient's movement is detected, the mechanical clamp arm 43 quickly makes adjustments and re-fixes the patient's body, effectively reducing the artifacts caused by the patient's movement. Experimental data show that after using the fixation device of the present invention, the probability of artifacts in MRI images is reduced from the original 30%-50% to less than 5%, making the MRI images clearer and more accurate, which helps doctors to more accurately judge the transformation of cerebral hemorrhage.

[0068] The high-precision pressure sensor 411 of the pressure sensor array 41 and the high resolution, low illumination characteristics of the image recognition camera 42, as well as the fusion processing of the data of the two, improve the accuracy of patient movement detection, provide a reliable basis for the precise adjustment of the mechanical clamping arm 43, and further ensure the image quality.

[0069] 3. Enhance adaptability

[0070] The mechanical clamp arm 43 of the patient adaptive fixation device 4 adopts a multi-joint structure, which can accurately adjust the fixation position according to the patient's body shape and position. For patients with larger bodies, the clamp arm can be extended to a suitable length and adjusted in angle so that the flexible fixation pad 44 can better fit the patient's body; for patients with smaller bodies, the clamp arm can also be adjusted accordingly to ensure the fixation effect. At the same time, the adjustable arc structure of the clamp head and the ±30° angle adjustment mechanism enable it to adapt to the body shapes of different patients, improving the applicability of the test.

[0071] The design of the quantum encoder disk 3 and the entire system reduces the restrictions on the patient's body size and physiological condition to a certain extent. Even for patients with special circumstances such as a small amount of metal fixtures in the body, accurate detection data can be obtained to a certain extent through optimized anti-interference design and adaptive adjustment mechanism, expanding the scope of application of MRI detection.

[0072] (IV) Improved system stability and reliability

[0073] Structural design optimization: The scanning bed 1 is made of high-strength alloy material and equipped with a stable support structure to ensure that there will be no deformation or displacement during the operation of the patient and the equipment, providing a stable basic platform for the entire detection process. The MRI scanning coil bracket 2 is made of high-strength, non-magnetic aluminum alloy and is anodized, which not only enhances corrosion resistance, but also improves structural stability, can effectively resist external vibration and interference, and ensure the normal operation of the quantum encoding disk 3 and the scanning coil.

[0074] Component quality and connection reliability: The deep groove ball bearing 6 is a high-precision product. The interference fit between the inner ring and the central axis of the quantum encoder disk 3 and the tight fit between the outer ring and the mounting hole of the scanning coil bracket 2 ensure the stability and smoothness of the quantum encoder disk 3 during high-speed rotation, and reduce the encoding error caused by mechanical vibration. The fixed base of the mechanical clamp arm 43 is made of cast iron and is firmly fixed to the frame of the scanning bed 1 by M8 bolts. It can always remain stable during frequent adjustments of position and angle without loosening or falling off. The transmission belt 73 is made of high-strength, wear-resistant rubber material and embedded with steel wire to enhance toughness, ensure that it will not break or slip during long-term high-speed transmission, and ensure the reliability of the mechanical transmission device.

[0075] Electromagnetic shielding and anti-interference measures: The housing 51 of the control system signal acquisition module 5 is made of metal material to form a good electromagnetic shielding environment, effectively blocking the influence of external electromagnetic interference on the internal central controller 52 and the signal acquisition device 53. The lines connecting various components are all shielded lines, such as the conductive line between the pressure sensor array 41 and the control system signal acquisition module 5 and the data line between the image recognition camera 42 and the control system signal acquisition module 5, which reduces the interference in the signal transmission process and ensures the accurate transmission of data, thereby improving the stability and reliability of the entire system.

[0076] (V) Advantages of data processing and analysis

[0077] Powerful data processing capability: The central controller 52 uses a high-performance microprocessor with fast data processing and computing capabilities. During the scanning process, it can receive and process a large amount of data transmitted from multiple components such as the pressure sensor array 41, the image recognition camera 42, the quantum encoding disk 3, and the scanning coil in real time. Through efficient algorithms, these data are quickly analyzed and processed, such as decoding quantum encoding signals, analyzing and judging patient movement data, and reconstructing MRI scan data, etc., to provide doctors with timely and accurate test results.

[0078] Data fusion and intelligent analysis: The pressure data collected by the pressure sensor array 41 and the image data collected by the image recognition camera 42 are fused and analyzed to more comprehensively and accurately determine the patient's movement status and body posture. Combined with the information on the location of cerebral hemorrhage encoded by the quantum encoding disk 3 and the data collected by the scanning coil, advanced data analysis algorithms can be used to conduct a more in-depth analysis and diagnosis of the transformation of cerebral hemorrhage. For example, by performing three-dimensional reconstruction and comparative analysis of MRI image data at different levels and angles, doctors can more intuitively understand the morphology, size changes and surrounding tissue conditions of the cerebral hemorrhage site, providing a more powerful basis for formulating treatment plans.

[0079] Data storage and management: The control system signal acquisition module 5 has a data storage function, which can classify and store all the data generated during the test, including the patient's basic information, the original data during the test, the processed image data, and the analysis results. The data storage uses a large-capacity storage medium and performs encryption to ensure the security and integrity of the data. At the same time, it is convenient for subsequent query, review and research of the data, providing rich data resources for medical research and clinical experience accumulation.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
