Description

Technical Field

[0001] This invention relates to the field of CT slip ring technology, and more specifically, to a bidirectional high-speed wireless data transmission CT slip ring and its usage method. Background Technology

[0002] CT, short for computed tomography, has wide applications in both medical and industrial fields. The "CT" we usually refer to primarily refers to medical CT scans. It's a cutting-edge medical imaging technology that uses X-ray beams to perform a tomographic scan of a part of the human body, and then reconstructs the image using a computer. The CT workflow can be summarized in three steps: "scanning - reconstruction - display."

[0003] Scan: The person lies on the examination bed and enters the center of a circular device called a "gantry." Inside the gantry, X-ray tubes and detectors, working as a precise pair, rotate at high speed around the person's body. The X-ray tubes emit extremely thin fan-shaped or cone-shaped X-ray beams, which penetrate the body and are received by the detectors on the opposite side.

[0004] Data Processing and Image Reconstruction: The detector converts the received intensity information into massive amounts of digital signals. The computer uses complex mathematical algorithms (such as filtering back-projection algorithms and iterative reconstruction algorithms) to process this data from thousands of angles. Finally, the computer calculates the X-ray attenuation coefficient of each point on the scanned cross-section and arranges them into a digital matrix.

[0005] The image shows that each number in this numerical matrix is ​​converted into a point of different gray levels on the image, called a "pixel." All these pixels are combined to form a cross-sectional anatomical image, which is what we see on a CT scan. On the image, high-density tissues (such as bones) appear white, low-density tissues (such as lungs and fat) appear black, and other soft tissues appear in different shades of gray.

[0006] In summary, since the scanned data is at one end of a high-speed rotation, the scanned data needs to be transmitted to the computer for algorithm processing in a timely manner; moreover, the X-ray tube and detector need to be commanded from the outside when they need to work. Therefore, a slip ring that can transmit data bidirectionally is needed to realize the transmission of data and commands.

[0007] The applicant discovered that existing slip rings can only achieve high-speed unidirectional data transmission, with control commands transmitted via contact slip rings. Due to the large size of CT slip rings, the control command loop is prone to failure. This invention's slip ring employs bidirectional high-speed data transmission, integrating control commands into the high-speed data transmission loop, reducing control command failures caused by contact slip ring transmission. This high-speed bidirectional transmission opens up more possibilities for the development of more advanced CT equipment.

[0008] Therefore, there is a particular need to design a bidirectional high-speed wireless data transmission CT slip ring and its usage method to solve the above-mentioned technical problems. Summary of the Invention

[0009] The purpose of this invention is to provide a bidirectional high-speed wireless data transmission CT slip ring and its usage method to solve the problems mentioned in the background art.

[0010] To solve the above-mentioned technical problems, the present invention provides a bidirectional high-speed wireless data transmission CT slip ring and its usage method, comprising: a slip ring rotor, the slip ring rotor being installed on the rotating end of the CT gantry and rotating with the rotating end of the CT gantry, a receiving module two being installed on one side of the slip ring rotor, and a transmitting module one being installed on the back of the slip ring rotor;

[0011] A slip ring stator is provided on one side of the slip ring rotor, and the two do not contact each other. The slip ring stator is fixed to the stationary end of the CT gantry and remains relatively stationary. A second transmission module is installed on the inner side of the slip ring stator.

[0012] A receiving module is provided at the outer end of the slip ring rotor, and the two do not contact each other. The receiving module is also installed at the stationary end of the CT gantry, keeping them relatively stationary.

[0013] Preferably, the first and second launch modules differ in their parameters and interface designs based on their different installation positions on the slip ring rotor and slip ring stator and their functional requirements.

[0014] Both the transmitting module one and the transmitting module two have signal processing, modulation, power amplification and transmission functions, as well as receiving, low-noise amplification, demodulation and signal restoration functions.

[0015] Preferably, the CT slip ring composed of the slip ring rotor and slip ring stator enables real-time communication and high-speed data transmission between the 360° infinitely rotating transmitting module and the corresponding receiving module through the omnidirectional antenna of transmitting module one, transmitting module two, receiving module one, and receiving module two, and the control commands are integrated into the high-speed data transmission loop.

[0016] Preferably, the rotor side is designed in an L-shape and passes through the slip ring stator, so that the receiving module two mounted on its top is located outside the slip ring stator, so that when the receiving module two rotates, it can pass through one side of the transmitting module two.

[0017] Preferably, the transmitting module is installed in the recessed part of the side end of the slip ring rotor, so that each time the transmitting module rotates, it will pass through the inner position of the receiving module.

[0018] Preferably, the slip ring rotor is divided into a rotor frame and an assembly bushing. The assembly bushing is clamped and installed in the recess of the rotor frame by bolts, and the assembly bushing is provided with a retaining plate, which is inserted into the groove of the rotor frame to strengthen the fixation.

[0019] Both the transmitting module one and the receiving module two are mounted on the rotor frame.

[0020] This invention also provides a method for using a CT slip ring for bidirectional high-speed wireless data transmission, comprising the following steps:

[0021] S1. Data is initiated from the stator end of the slip ring and first transmitted to the first transmitting module installed on the rotor of the slip ring. The first transmitting module then transmits the data in the form of a wireless signal.

[0022] S2. Once the receiving module installed on the CT gantry receives the signal, it transmits it to the slip ring rotor through internal circuitry.

[0023] S3. The slip ring rotor transmits the data signal from the transmitting module two, which is then received by the receiving module two installed on the slip ring rotor, and finally returns to the slip ring stator to complete a complete data transmission cycle.

[0024] The beneficial effects of this invention are:

[0025] This invention breaks away from the traditional slip ring design. The receiving module, originally used at the stator end, is repositioned on the rotor side of the slip ring to receive signals from the stator. Conversely, the transmitting module, originally intended for the rotor end, is placed at the stator end to transmit signals from the stator side. This enables the slip ring to transmit bidirectional, high-speed data, allowing control commands to be integrated into the high-speed data transmission loop and reducing control command failures caused by contact-type slip ring transmission. This high-speed bidirectional transmission opens up more possibilities for the development of more advanced CT equipment. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0035] like Figures 1-4 As shown, this invention discloses a bidirectional high-speed wireless data transmission CT slip ring, comprising a slip ring rotor 1, which is mounted on the rotating end of the CT gantry and rotates with the rotating end of the CT gantry. A receiving module 2 3 is mounted on one side of the rotor edge 101 of the slip ring rotor 1, and a transmitting module 4 is mounted on the back of the slip ring rotor 1. A slip ring stator 2 is located on one side of the slip ring rotor 1, and the two are not in contact. The slip ring stator 2 is fixed to the stationary end of the CT gantry, maintaining relative stillness. A transmitting module 2 5 is mounted on the inner side of the slip ring stator 2, and a receiving module 6 is located at the outer end of the slip ring rotor 1, and the two are not in contact. The receiving module 6 is also mounted on the stationary end of the CT gantry, maintaining relative stillness. The above structural design lays the physical foundation for subsequent wireless data transmission, enabling the modules to be reasonably distributed on the rotating and stationary ends of the CT gantry, meeting the data transmission requirements of the CT equipment during rotational scanning.

[0036] Transmitter Module 1 (4) and Transmitter Module 2 (5) differ in their parameters and interface designs based on their different installation positions on the slip ring rotor 1 and slip ring stator 2, as well as their functional requirements. Both Transmitter Module 1 (4) and Transmitter Module 2 (5) have signal processing, modulation, power amplification, and transmission functions, as well as receiving, low-noise amplification, demodulation, and signal restoration functions. The modules can be specifically optimized according to the actual needs of different positions, while ensuring the integrity of the module functions. This improves the applicability and flexibility of the modules and helps to achieve efficient data transmission and processing.

[0037] The CT slip ring, composed of slip ring rotor 1 and slip ring stator 2, achieves real-time communication and high-speed data transmission between the 360° infinitely rotating transmitting module and the corresponding receiving module through the omnidirectional antennas of transmitting module 1 4, transmitting module 2 5, receiving module 1 6, and receiving module 2 3. Furthermore, control commands are integrated into the high-speed data transmission loop, which solves the limitations of traditional slip rings in rotational transmission, avoids signal interruption caused by rotation, improves the efficiency and reliability of data transmission, reduces the risk of control command transmission failure, and enhances the overall performance of the CT equipment.

[0038] The rotor side 101 is L-shaped and passes through the slip ring stator 2, so that the receiving module 2 3 mounted on its top is located on the outside of the slip ring stator 2. This allows the receiving module 2 3 to pass by the side of the transmitting module 2 5 when it rotates. The transmitting module 4 is installed in the recessed part of the side end of the slip ring rotor 1, so that the transmitting module 4 will pass by the inside of the receiving module 6 each time it rotates. The above design improves the efficiency of data linkage transmission between modules, optimizes the relative positional relationship between modules, and improves the efficiency of data linkage transmission between modules. This allows data to be transmitted between different modules more timely and accurately during rotation, further improving the real-time performance and effectiveness of data transmission.

[0039] The slip ring rotor 1 is divided into a rotor frame 102 and an assembly bushing 103. The assembly bushing 103 is snapped into the recess of the rotor frame 102 by bolts, and the assembly bushing 103 is provided with a retaining plate 104, which snaps into the groove of the rotor frame 102 for reinforcement and fixation. The transmitting module 1 4 and the receiving module 2 3 are both installed on the rotor frame 102, which ensures the stability and reliability of the slip ring rotor, facilitates the installation and maintenance of the modules, and improves the overall structural strength of the slip ring. This helps the slip ring maintain stable performance during the long-term operation of the CT equipment and reduces failures and data transmission problems caused by structural loosening.

[0040] This invention also discloses a method for using a CT slip ring for bidirectional high-speed wireless data transmission, see [link to relevant documentation]. Figure 5 And includes the following steps:

[0041] S1. Data is initiated from the slip ring stator 2 end and first transmitted to the transmitter module 4 installed on the slip ring rotor 1. The transmitter module 4 then transmits the data in the form of a wireless signal.

[0042] S2. After receiving the signal, the receiving module 6 installed on the CT gantry transmits it to the slip ring rotor 1 through the internal circuit.

[0043] S3. The slip ring rotor 1 transmits the data signal from the transmitting module 2 5, which is then received by the receiving module 2 5 installed on the slip ring rotor 1, and finally returns to the slip ring stator 2 to complete a complete data transmission cycle.

[0044] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
