[0038] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the term "comprising" and any variations thereof in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion. In the description of embodiments of this application, technical terms such as "first," "second," "third," and "fourth" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary or secondary relationship of the indicated technical features. In the description of embodiments of this application, "a plurality of" means two or more, unless otherwise explicitly defined.

[0040] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical term "connection" and other terms should be interpreted broadly. For example, it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal connection of two components or the interaction between two components.

[0042] SPECT is a medical imaging technique used to detect the physiological functions and metabolism of internal tissues and organs. Typically, a grid collimator is placed on the photon incident surface at the front of the SPECT probe to ensure that only photons at a selected angle hit the detector crystal. Due to variations in clinical protocols and scanning sites, a large number of collimators of different models and specifications are often required. Since the collimator model directly affects clinical workflow and the accuracy of image reconstruction parameters, the scanning equipment must be able to identify the collimator model after installation. The accuracy of this identification is crucial to the effectiveness of clinical diagnostic applications.

[0043] In related technologies, most methods employ multiple contact switches to identify the collimator model, with different models triggering different contact switches. For example, using two contact switches can achieve two... 2 -1 = 3 types of collimators can be identified; 3 contact switches can achieve 2 3 Recognizing seven collimator models (-1=7) becomes difficult with this equipment if sufficient contact switches are not installed. Adding additional collimator models would be challenging, significantly limiting the clinical application of dual-probe SPECT devices. Furthermore, mechanical contact recognition requires high precision in the installation and positioning of the collimator across all dimensions; otherwise, there is a risk of failure to trigger or false triggering. Additionally, the mechanical contact triggering switch during collimator replacement can cause significant impact on the contact switches during installation and removal, potentially leading to damage or false triggering and system errors.

[0044] Based on this, this application provides a collimator identification device. By setting an RFID tag in the collimator identification device, parameter information such as the model of the collimator can be written into the RFID tag. At the same time, a signal reader is set up so that the RFID tag and the signal reader can communicate wirelessly. Thus, the signal reader can read the model information written in the RFID tag without contact, thereby realizing accurate identification of the collimator's model information. It has the characteristics of timely response, accuracy, convenience and efficiency in identification.

[0045] The detailed implementation process of the collimator recognition device provided in this application will be described below through specific embodiments. Figure 1 The diagram shown is a schematic of a collimator identification device provided in an embodiment of this application.

[0046] The collimator identification device includes an RFID tag 10 and a signal reader 20. The signal reader 20 is connected to the host computer of the medical scanning equipment, and the RFID tag 10 is installed on the collimator of the medical scanning equipment.

[0047] RFID tag 10 is used to store collimator parameter information;

[0048] Signal recognizer 20 is used to identify and / or write collimator parameter information;

[0049] Radio frequency identification tag 10 and signal reader 20 communicate without contact.

[0050] In this embodiment, the radio frequency identification tag 10 is a device that reads information using radio frequency identification (RFID) technology. That is, it uses radio waves to transmit and store data, and can quickly read the information on the tag without contact. The entire identification process does not require manual intervention and can work in various harsh environments. It is quick and convenient to operate.

[0051] Typically, RFID tags consist of a chip and an antenna. The chip stores information, while the antenna receives and transmits signals. There are various types of RFID tags, including active tags, passive tags, semi-active tags, high-frequency tags, ultra-high-frequency tags, low-frequency tags, anti-metal tags, high-temperature resistant tags, and flexible tags. Different types of tags can be selected according to different scenarios and requirements. In one embodiment, a passive tag can be used as the RFID tag 10 in this application embodiment. Passive tags do not require an internal power supply and are powered by the electromagnetic waves of the reader, resulting in lower costs.

[0052] The signal identifier 20 is a device for transmitting radio frequency signals and receiving response signals from the RFID tag, in order to write collimator parameter information into and read collimator parameter information from the RFID tag 10. The signal identifier 20 communicates with the RFID tag 10 without contact. In this embodiment, the RFID tag 10 contains collimator model information; therefore, the signal identifier 20 can write the collimator model information into the RFID tag 10 and can also read the written collimator model information from the RFID tag 10.

[0053] A collimator is an optical element used to adjust the direction and shape of light rays, making them parallel beams. Collimators are used in medical scanning equipment, such as CT (Computed Tomography) and SPECT devices. Taking a dual-probe SPECT device as an example, the collimator in the SPECT device is located in front of the detector crystal and is used to control the incident direction of photons to ensure the clarity of the acquired image. This application does not limit the type of collimator; it can be a parallel-aperture collimator, a pinhole collimator, a fan-shaped collimator, a focusing collimator, a diffuser collimator, etc.

[0054] In this embodiment of the application, the signal identifier 20 is connected to the host computer of the medical scanning device. The signal identifier 20 can obtain the model information that needs to be written in the radio frequency identification tag 10 from the host computer, and can also upload the model information read from the radio frequency identification tag 10 to the host computer.

[0055] An RFID tag 10 is attached to the collimator of a medical scanning device. A signal reader 20 communicates wirelessly with the RFID tag 10, and the signal reader 20 is also wiredly connected to the host computer of the medical scanning device. Each type of collimator corresponds to a different RFID tag 10, and each RFID tag 10 contains the model information of the corresponding collimator. It should be noted that, in addition to storing the model information of the collimator, the RFID tag 10 can also store other parameter information such as the collimator manufacturer, manufacturing date, and material information.

[0056] In practical applications, the host computer can send the model information to be written to the signal identifier 20, and the signal identifier 20 will then write the received model information onto the corresponding collimator's RFID tag 10. After the collimator is installed, the signal identifier 20 can also identify the collimator's model information from the collimator's RFID tag 10 and transmit the identified model information to the host computer, which will then determine whether the current collimator is consistent with the collimator to be replaced based on the model information.

[0057] The collimator identification device provided in this application includes an RFID tag and a signal reader. The signal reader is connected to the host computer of the medical scanning equipment. The RFID tag is installed on the collimator of the medical scanning equipment. The RFID tag is used to store collimator parameter information, and the signal reader is used to identify and / or write the collimator parameter information. The RFID tag and the signal reader communicate non-contactly. This collimator identification device, by setting an RFID tag in the collimator identification device, allows parameter information such as the collimator model to be written into the RFID tag. Simultaneously, the signal reader enables wireless communication between the RFID tag and the signal reader, allowing the signal reader to read the written model information from the RFID tag without contact. This achieves accurate identification of the collimator model information and features timely response, accuracy, convenience, and high efficiency.

[0058] As can be seen from the above embodiments, the signal identifier 20 can both write the collimator model number into the RFID tag 10 and identify the collimator model number information from the RFID tag 10. Based on this, an embodiment is provided to illustrate the structure of the signal identifier 20 and the function of each component.

[0059] In one exemplary embodiment, such as Figure 2 As shown, the signal identifier 20 includes an RFID tag antenna 21 and a tag reader / writer 22; the RFID tag antenna 21 and the tag reader / writer 22 are connected by a cable.

[0060] The signal recognizer 20 is mounted on the rack of the medical scanning equipment.

[0061] In this embodiment, the RFID tag antenna 21 is the transponder antenna of the RFID tag, which is a type of communication induction antenna. The RFID tag antenna 21 transmits radio frequency signals between the RFID tag 10 and the tag reader 22. Its main function is to receive and radiate electromagnetic wave signals to realize wireless reading and writing of information stored in the tag.

[0062] The tag reader / writer 22 is a reading and writing terminal device mainly used for reading and writing data in RFID tags. It can be installed on the rack of a medical scanning device. In practical applications, the tag reader / writer 22 installed on the rack can write the model information to be written onto the RFID tag 10 of the corresponding collimator, identify the written model information from the RFID tag 10, and send the model information to the host computer of the medical scanning device for subsequent operations.

[0063] In one embodiment, such as Figure 3 As shown, the tag reader 22 includes a signal writing board 220 and an antenna receiving board 221; the signal writing board 220 is connected to the antenna receiving board 221 through a groove in the antenna receiving board 221.

[0064] Both the signal writing board 220 and the antenna receiving board 221 are electronic devices used to write model information into the RFID tag 10. The antenna receiving board 221 is used not only for writing model information but also for reading model information from the RFID tag 10. The signal writing board 220 and the antenna receiving board 221 are detachably connected via a groove in the antenna receiving board 221. When the signal writing board 220 is inserted into the antenna receiving board 221, they are connected; when the signal writing board 220 is removed from the antenna receiving board 221, they are disconnected.

[0065] For example, in practical use, the signal writing board 220 can be connected to the antenna receiving board 221 via a groove in the antenna receiving board 221. The host computer sends the model information to be written to the signal writing board 220, which then transmits the model information to the antenna receiving board 221. The antenna receiving board 221 then transmits the model information to the RFID tag 10 via the RFID tag antenna 21. The chip in the RFID tag 10 saves the model information, thus completing the model information writing operation. When identifying the model information, the RFID tag 10 sends the saved model information as a radio frequency signal. The antenna receiving board 221 identifies the model information sent by the RFID tag 10 via the RFID tag antenna 21 and transmits the model information to the host computer for processing.

[0066] In this embodiment, the signal writing board 220 is also connected to a host computer via a serial cable. The host computer transmits the collimator parameter information to be written to the signal writing board 220 via the serial cable. A serial cable is a line used for serial communication, primarily for data transmission between devices. For example, when writing model information into the RFID tag 10, the host computer can transmit the model information to be written to the signal writing board 220 via the serial cable, and then the signal writing board 220 transmits it to the antenna receiving board 221 for information writing. When the antenna receiving board 221 identifies the model information in the RFID tag 10, it can also transmit the identified model information to the signal writing board 220, which then sends the model information to the host computer via the serial cable. Alternatively, when identifying model information, the antenna receiving board 221 can be connected to the host computer via a cable, so that after identifying the model information in the RFID tag 10, the antenna receiving board 221 can directly transmit it to the host computer via the cable.

[0067] In this embodiment, the signal writing board 220 and the antenna receiving board 221 each include different structural components, and these different components perform different operations when reading and writing model information. Therefore, in one embodiment, the signal writing board 220 includes an encoding circuit and a transmitter; the antenna receiving board 221 includes a receiver, a decoding circuit, and a control circuit.

[0068] The encoding circuit encodes the model information to be written and sends the encoded model information to the antenna receiving board 221 through the transmitter; the antenna receiving board 221 sends the encoded model information to the RFID tag 10 through the RFID tag antenna 21.

[0069] The receiver receives the model information sent by the RFID tag 10 through the RFID tag antenna 21, the decoding circuit decodes the received model information, and the control circuit sends the decoded model information to the host computer.

[0070] In this embodiment, the signal writing board 220 is mainly used when writing model information, and it includes an encoding circuit for encoding the model information to be written and a transmitter for sending the model information to be written to the antenna receiving board. The antenna receiving board 221 is used both when writing and reading model information, and it includes a receiver for receiving model information, a decoding circuit for decoding model information, and a control circuit for processing model information.

[0071] In practical applications, when model information is written into the RFID tag 10, the host computer sends the model information to be written to the signal writing board 220. The encoding circuit in the signal writing board 220 first encodes the model information to be written to obtain the encoded model information, and then sends the encoded model information to the transmitter. The transmitter then sends the encoded model information to the antenna receiving board 221. After receiving the encoded model information, the antenna receiving board 221 sends the encoded model information to the RFID tag 10 through the RFID tag antenna 21. Then, the chip in the RFID tag 10 saves the encoded model information, completing the model information writing operation.

[0072] When the model information is identified from the RFID tag 10, the RFID tag 10 actively sends the stored model information in the form of an RFID signal. The receiver in the antenna receiver board 221 receives the model information sent by the RFID tag 10 through the RFID tag antenna 21. Then, the decoding circuit decodes the received model information to obtain the decoded model information, and the control circuit transmits the decoded model information to the host computer to complete the model information identification operation.

[0073] The collimator identification device provided in this application includes a signal identifier comprising a radio frequency identification (RFID) tag antenna and a tag reader / writer. The RFID tag antenna and the tag reader / writer are connected via a cable. The signal identifier is mounted on the rack of a medical scanning device. In this collimator identification device, by incorporating an RFID tag antenna and a tag reader / writer within the signal identifier, the tag reader / writer can receive and transmit signals via the RFID tag antenna. This allows the model information to be written into and read from the RFID tag using the RFID tag antenna, achieving accurate identification of the collimator's model information and improving identification accuracy and efficiency.

[0074] As can be seen from the above embodiments, the signal identifier in this application embodiment can be a device that can both write and read model information. Alternatively, the signal identifier can be divided into a writing device for writing model information and a reading device for reading model information. Based on this, in an exemplary embodiment, such as... Figure 4 As shown, the signal identifier 20 includes a tag writer 23 and a tag reader 24;

[0075] The label writer 23 is located in the workbench; the label reader 24 is located on the rack of the medical scanning equipment.

[0076] In this embodiment, the tag writer 23 is a device that writes model information to the RFID tag 10, and the tag reader 24 is a device that reads model information from the RFID tag 10.

[0077] In one embodiment, such as Figure 5 As shown, the tag writer 23 includes an RFID tag antenna 21, an antenna receiving board 221, and a signal writing board 220. The RFID tag antenna 21 is connected to the antenna receiving board 221 via a cable, and the signal writing board 220 is connected to the antenna receiving board 221 via a groove in the antenna receiving board 221.

[0078] The signal writing board 220 includes an encoding circuit and a transmitter; the encoding circuit encodes the model information to be written and sends the encoded model information to the antenna receiving board 221 through the transmitter; the antenna receiving board 221 sends the encoded model information to the RFID tag 10 through the RFID tag antenna 21.

[0079] In one embodiment, such as Figure 6 As shown, the tag reader 24 includes an RFID tag antenna 21 and an antenna receiving board 221; the RFID tag antenna 21 is connected to the antenna receiving board 221 via a cable.

[0080] The antenna receiving board 221 includes a receiver, a decoding circuit, and a control circuit. The receiver receives the model information sent by the RFID tag 10 through the RFID tag antenna 21, the decoding circuit decodes the read model information, and the control circuit sends the decoded model information to the host computer.

[0081] The composition and operation of the RFID antenna tag, antenna receiving board, and signal writing board are the same as those in the previous embodiments, and can be referred to the description in the previous embodiments, so they will not be repeated here.

[0082] The collimator identification device provided in this application includes a tag writer and a tag reader in the signal identifier. The tag writer is disposed in the workbench, and the tag reader is disposed on the rack of the medical scanning equipment. In this collimator identification device, by setting the tag writer in the signal identifier, the tag writer acts as a device for writing model information. Through its various components, it writes the model information to be written into the RFID tag, improving the convenience and efficiency of model information writing. At the same time, the tag reader is set up to act as a device for identifying model information. Through its various components, it reads the model information from the RFID tag, achieving accurate identification of the collimator model information and improving the accuracy and efficiency of model information identification.

[0083] In another embodiment, such as Figure 7a As shown, the RFID tag antenna, antenna receiving board, and signal writing board in the collimator identification device can also be mounted on the collimator. The RFID tag antenna is connected to the antenna receiving board, and the signal writing board is connected to the antenna receiving board through a groove on the antenna receiving board. Figure 7b As shown, the RFID tag antenna, antenna receiving board, and signal writing board are all mounted on the collimator. However, it differs from... Figure 7a The difference is that the antenna receiver board and the signal writing board are connected by cables. For example... Figure 8 The image shown is a schematic diagram of an RFID tag.

[0084] In this embodiment, when model information needs to be written, the signal writing board can be connected to the host computer via a serial cable, and the signal writing board can be connected to the antenna receiving board via the groove of the antenna receiving board (or the signal writing board and the antenna receiving board can be connected via a cable). The host computer sends the model information to be written to the signal writing board via the serial cable, the signal writing board then transmits the model information to be written to the antenna receiving board, the antenna receiving board sends the model information to be written to the RFID tag via the RFID tag antenna, and the RFID tag chip saves the model information to be written, completing the model information writing operation.

[0085] When signal information needs to be read, the signal writing board can be removed from the antenna receiving board, and the antenna receiving board can be connected to the host computer via a cable. The RFID tag transmits the stored model information to the antenna receiving board through the RFID tag antenna. The antenna receiving board then transmits the received model information to the host computer via a cable, completing the model information reading operation.

[0086] In this embodiment, by setting up an RFID tag, an antenna receiving board, and an information writing board in the collimator identification device, the signal writing board and the antenna receiving board can write the model information to be written into the RFID tag through the RFID tag antenna. This allows the antenna receiving board to read the written model information from the RFID tag without contact, thereby achieving accurate identification of the collimator's model information.

[0087] In one embodiment, this application also provides a medical device, which includes a frame, a radiation source, a collimator, and a collimator identification device as described in any of the foregoing embodiments; wherein the radiation source and the collimator are both disposed on the frame; the collimator is located on the beam exit path of the radiation source and is used to adjust the radiation field; the collimator identification device is used to identify collimator parameter information and determine the type of collimator based on the collimator parameter information.
