Description

[Technical field]

[0001] The embodiments disclosed in this specification and the drawings relate to an information display device, a magnetic resonance imaging system, and an information display system. [Background technology]

[0002] A magnetic resonance imaging (MRI) device is an imaging device that excites the nuclear spins of a subject (e.g., a patient) placed in a static magnetic field generated by a static magnetic field magnet with a radio frequency (RF) signal at the Larmor frequency, and generates an image by reconstructing the magnetic resonance signal (MR (Magnetic Resonance) signal) generated from the subject in response to the excitation. In the imaging room where the magnet stand containing the static magnetic field magnet is located, a safety line called a 5 Gauss line is set around the magnet stand. If a magnetic object is brought inside the safety line, there is a risk of an accident due to attraction to the MRI device or an effect on the image quality of the reconstructed image (metal artifacts).

[0003] Therefore, before entering the imaging room where the magnet stand is located, users such as patients, medical staff, and hospital personnel must make sure that they are not carrying any magnetic material, and the safety of each user must be confirmed. Currently, the bringing in of magnetic material is checked by metal detectors, visual inspection, and verbal inquiries.

[0004] However, metal detectors have problems in that they are not used because they do not have a high level of accuracy in detecting magnetic objects and they often malfunction. Also, visual and verbal inquiries are prone to human error due to oversights, etc. [Prior art documents] [Patent documents]

[0009] Hereinafter, embodiments of an information display device, a magnetic resonance imaging system, and an information display system will be described in detail with reference to the drawings.

[0010] [First embodiment] Fig. 1 is a block diagram showing an example of the configuration of a magnetic resonance imaging system 1 according to the first embodiment. As shown in Fig. 1, the magnetic resonance imaging system 1 includes an information display device 2 and an MRI device 3. The information display device 2 and the MRI device 3 are connected to each other so as to be able to communicate with each other via a network 4. In the following, it is assumed that data is transmitted and received between the devices via the network 4, and the phrase "via the network 4" will be omitted when describing data transmission and reception.

[0011] The information display device 2 is a device for recognizing a user of the MRI apparatus 3 (hereinafter referred to as "MRI user"), and for confirming that the MRI user is not wearing any magnetic material, that there are no problems with implants, and that the MRI apparatus 3 can be used safely. MRI users include, for example, a person to be imaged (e.g., a patient) who is to be imaged by the MRI apparatus 3, staff such as an imaging technician who operates the MRI apparatus 3, other medical professionals, hospital personnel, etc. The information display device 2 is carried by a magnetic material checker who is different from the MRI user, and is used, for example, to check whether or not there are no problems with magnetic materials before the MRI user enters the imaging room. The magnetic material checker is, for example, a staff member such as an imaging technician. Below, an example will be described in which the person to be imaged is a patient.

[0012] The information display device 2 is, for example, a tablet terminal, a smartphone, a glasses-type wearable device, etc. As shown in FIG. 1, the information display device 2 includes a display 21, an input interface 22, a network interface 23, a processing circuit 24, a memory circuit 25, a camera 26, and a microphone 27.

[0013] The display 21 of the information display device 2 is configured by a general display output device such as a liquid crystal display or an OLED (Organic Light Emitting Diode) display. The display 21 is an example of a display unit. The input interface 22 is configured by an input device (e.g., a touch panel, etc.) that can be operated by an operator and an input circuit that inputs a signal from the input device, and outputs an operation input signal corresponding to an operation by the operator to the processing circuit 24. The network interface 23 implements various information communication protocols according to the form of the network 4. The network interface 23 communicates with the MRI apparatus 3 via the network 4 according to the various protocols. The network interface 23 is an example of a transmitting / receiving unit.

[0014] The processing circuitry 24 realizes a function of overall control of the information display device 2. The processing circuitry 24 is also a processor that reads out and executes a program stored in the storage circuitry 25 to execute a process according to an operator's operation, a process synchronized with the MRI apparatus 3, and the like. The processor of the processing circuitry 24 realizes an information acquisition function 241, a confirmation generation function 242, and a display control function 243. These functions are stored in the storage circuitry 25 in the form of a program, for example.

[0015] The information acquisition function 241 includes a function of acquiring user information, which is information about an MRI user, from the MRI device 3. The confirmation generation function 242 includes a function of generating confirmation information indicating items that the MRI user should confirm regarding the holding of a magnetic material, based on the user information acquired by the information acquisition function 241. The display control function 243 includes a function of displaying the confirmation information generated by the confirmation generation function 242 on the display 21.

[0016] The memory circuitry 25 has a configuration including a processor-readable recording medium, such as a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, a hard disk, an optical disk, etc., and stores programs, parameter data, etc. used by the processing circuitry 24. The memory circuitry 25 is an example of a memory unit.

[0017] The camera 26 is used to capture an image of the MRI user. The microphone 27 is used to input voice data. The processing circuit 24 stores the voice data or voiceprint data converted from the voice data in the memory circuit 25. The voice data includes data showing the voice of the MRI user for identity verification, data showing communication between the MRI user and a magnetic material inspector, etc.

[0018] The MRI apparatus 3 images an imaging region of a patient by magnetic resonance imaging. As shown in Fig. 1, the MRI apparatus 3 includes a magnet gantry 31, a bed 32, a control cabinet 33, and a console 34. The magnet gantry 31 and the bed 32 are disposed, for example, in a shielded room called an imaging room. Meanwhile, the control cabinet 33 is disposed, for example, in a machine room. The console 34 is disposed, for example, in a control room adjacent to the imaging room.

[0019] The magnet gantry 31 is a device for imaging an imaging region of a patient, and includes a static magnetic field magnet, a gradient magnetic field coil, and a WB coil housed in a cylindrical housing. The magnet gantry 31 forms an imaging opening (also called a "bore") into which a bed top is inserted. The bed 32 has a bed top on which a patient is placed, and the bed body inserts the bed top into the imaging opening. The control cabinet 33 is a device for controlling the magnet gantry 31, and includes gradient magnetic field power supplies (for the X-axis, Y-axis, and Z-axis), an RF receiver, an RF transmitter, and a sequence controller.

[0020] The console 34 is a device that controls the entire MRI apparatus 3 and generates a magnetic resonance image. The console 34 includes a display 341, an input interface 342, a network interface 343, a processing circuitry 344, and a storage circuitry 345. The console 34 is an example of an image processing device.

[0021] The display 341 is a display device such as a liquid crystal display panel, a plasma display panel, an organic EL panel, or the like. The display 341 is an example of a display unit. The input interface 342 is composed of various input devices such as a mouse, a keyboard, a trackball, a touch panel, and the like, which allow an operator to input various pieces of information, and an input circuit that inputs signals from the input devices, and outputs an operation input signal corresponding to an operation by the operator to the processing circuit 344. The network interface 343 implements various information communication protocols according to the form of the network 4. The network interface 343 is communicatively connected to the information display device 2 via the network 4 in accordance with the various protocols. The network interface 343 is an example of a transmitting / receiving unit.

[0022] The processing circuitry 344 realizes a function of controlling the console 34. The processing circuitry 344 is a processor that reads and executes a program stored in the memory circuitry 345 to execute a process according to an operation by an operator, a process synchronized with the information display device 2, and the like. The memory circuitry 345 has a configuration including a processor-readable recording medium, such as a semiconductor memory element such as a RAM (Random Access Memory), a flash memory, a hard disk, an optical disk, and the like, and stores a program, parameter data, and the like used by the processing circuitry 344. The memory circuitry 345 stores, for example, an imaged person ID (Identification) (for example, a patient ID), patient information, and imaging conditions in association with each other. The memory circuitry 345 is an example of a storage unit. Hereinafter, a case where the imaged person ID is a patient ID will be described as an example.

[0023] The console 34 controls the entire MRI apparatus 3 using these components. Specifically, the console 34 receives imaging conditions and various other information and instructions through the operation of the input interface 342 by an operator such as an imaging technician. The processing circuitry 344 then causes the control cabinet 33 (more specifically, the sequence controller) to execute a scan based on the input imaging conditions. Meanwhile, the processing circuitry 344 reconstructs an image based on data transmitted from the control cabinet 33. The reconstructed image is displayed on the display 341 or stored in the memory circuitry 345.

[0024] Fig. 2 is a sequence chart showing an example of processing of the magnetic resonance imaging system 1 according to the first embodiment. Hereinafter, processing of the information display device 2 and the MRI apparatus 3 will be described with reference to Fig. 2. This processing is applied to a patient who is scheduled to undergo imaging.

[0025] In this case, the user information is at least one of imaged person information (e.g., patient information) which is information about a patient as an MRI user, and imaging conditions applied to the patient. Hereinafter, an example will be described in which the imaged person information is patient information. In other words, the user information is a higher-level concept than the patient information and imaging conditions. When the user information includes patient information, the patient information includes at least one of the patient's image, attributes, belongings, health condition, information about the implant, and an application from the patient. Note that the information about the implant includes, for example, the position, size, compatibility information, model number, etc. of the implant. When the user information includes imaging conditions, the imaging conditions include at least one of the imaging site of the patient, the presence or absence of a contrast agent, electrocardiogram synchronization, respiratory synchronization, and information about the imaging method such as the type of imaging sequence. Note that the types of imaging sequences include the SE (Spin-Echo) method, the EPI (Echo Planar Imaging) method, and the SE-EPI method which is a combination of these methods.

[0026] In step S1, in the information display device 2, the information acquisition function 241 creates an inquiry for patient information and imaging conditions, specifying a patient ID unique to the patient. The operator of the information display device 2 may directly input the patient ID to the input interface 342, or may read a two-dimensional code (e.g., QR code (registered trademark)) or one-dimensional code (e.g., barcode) held by the patient using a dedicated reader. Then, the network interface 23 transmits the inquiry to the MRI device 3.

[0027] In step S2, in the MRI apparatus 3, the network interface 343 of the console 34 receives an inquiry about the patient information and imaging conditions from the information display device 2.

[0028] In step S3, in the MRI apparatus 3, the processing circuitry 344 extracts the patient ID included in the inquiry, and reads out the patient information and the imaging conditions associated with the patient ID from the storage circuitry 345. The network interface 343 transmits the patient information and the imaging conditions read out by the processing circuitry 344 to the information display device 2.

[0029] In step S4, in the information display device 2, the network interface 23 receives the patient information and imaging conditions from the MRI apparatus 3.

[0030] In step S5, in the information display device 2, the confirmation generating function 242 generates confirmation information based on the received patient information and imaging conditions. The confirmation generating function 242 appropriately selects items to be included in the confirmation information, for example, by specifying what kind of imaging is to be performed on the patient from the imaging conditions.

[0031] In step S6, in the information display device 2, the display control function 243 causes the display 21 to display the confirmation information generated by the confirmation generating function 242.

[0032] In step S7, the magnetic material checker refers to the confirmation information displayed on the display 21 of the information display device 2, checks with the MRI user about each item of the confirmation information, and inputs the confirmation results into the input interface 22. The input interface 22 acquires the confirmation results as text data.

[0033] The magnetic material inspector may take a video of the MRI user or record the voice of the MRI user as the inspection result. In this case, the camera 26 and the microphone 27 acquire the inspection result as video data. Alternatively, the microphone 27 acquires the inspection result as voice data.

[0034] In step S8, when the information display device 2 has finished checking the patient for all check items in the check information, the information acquisition function 241 stores record information in which the check information and the check result are associated in the memory circuitry 25. When the check result is text data, it can be checked immediately. When the check result is video data or audio data, it can be used to verify the circumstances when an accident occurred. At this time, when all items indicated by the check information have been checked, the display control function 243 may cause the display 21 to display that the MRI device 3 is safe to use.

[0035] The display control function 243 may display the confirmation information on the display 21 of the information display device 2, or may display the confirmation information on the display 341 of the console 34 of the MRI apparatus 3.

[0036] Therefore, the display of the confirmation information and the acquisition of the confirmation result may be performed in the MRI apparatus 3, not in the information display device 2. In this case, the network interface 23 of the information display device 2 transmits the confirmation information to the MRI apparatus 3 in step S6.

[0037] Next, in step S11, in the console 34 of the MRI apparatus 3, the network interface 343 receives the confirmation information from the information display device 2. Then, the processing circuitry 344 causes the display 341 to display the received confirmation information.

[0038] In step S12, the magnetic material checker refers to the confirmation information displayed on the display 341, checks with the patient about each item of the confirmation information, and inputs the confirmation results to the input interface 342. The input interface 342 acquires the confirmation results. The network interface 343 transmits the acquired confirmation results to the information display device 2.

[0039] Then, in step S7, in the information display device 2, the network interface 23 receives the confirmation result from the MRI apparatus 3.

[0040] The user information may be medical staff information, which is information about medical staff as MRI users. That is, users of the MRI apparatus 3 include not only subjects to be imaged, such as patients, but also medical staff, such as imaging staff.

[0041] Fig. 3 is a diagram showing classification items of confirmation information according to the first embodiment and specific examples of the items. As shown in Fig. 3, the confirmation information is classified into mandatory confirmation items, magnetic material carry-in confirmation items, implant confirmation items, and imaged person application confirmation items. Below, an example will be described in which the imaged person application confirmation items are patient application confirmation items.

[0042] Mandatory check items are items that should be checked regardless of the patient's condition or the imaging content. Items that should be checked include common check items such as "Does the patient need an auxiliary device or an assistant?", "Does the patient have claustrophobia?", "Has the patient changed into examination clothing?", and "Does the patient have non-magnetic equipment to bring with them?". When patient information includes gender and gender includes female, for example, female physical information such as "Whether the patient is pregnant or breastfeeding?" is included in the items that should be checked. In addition, when imaging conditions include contrast, items related to the contrast agent such as "Is the contrast agent related to a history of side effects or contraindications?" are included in the items that should be checked.

[0043] The magnetic material carry-on check items are items to be checked regarding whether magnetic materials are carried on or not, and include items to be checked according to imaging information, which is information regarding imaging of patients. The items to be checked include, for example, items related to personal items such as "Are you carrying dentures, necklaces, adhesive heating pads or medicines, wristwatches, underwear made of metallic fibers, etc."

[0044] When the imaging conditions indicate that a specific part is to be imaged, the items to be checked include items related to the imaging part, such as "Are there any undergarments with wires, metal fittings, or zippers?" and "Are there any bolts in the imaging area including the specific part?" For example, when imaging the head, it is no problem if there is a bolt on the foot. On the other hand, when imaging the knee, if there is a bolt on the knee, detailed check items are generated. When the imaging conditions indicate that a fetus is to be imaged, the items to be checked include items related to the mother, such as the number of weeks pregnant.

[0045] Implant check items are items to be checked regarding the patient's implants, and include items to be checked depending on the patient's history. For example, items related to implants, such as "Are there any metals in the body, embolization coils, venous filters, etc.?" are included in the items to be checked. If the patient information includes a history of accidents or injuries, items related to the effects of accidents or injuries, such as "Are there any metal pieces in the body?" are included in the items to be checked. Furthermore, if the patient information includes a past application for an implant, or if the patient information indicates the possibility of an implant based on the medical history or surgical history, items related to the possibility of an implant, such as "Are the implants in question present?" are included in the items to be checked.

[0046] The Patient Application Check Items are items that should be checked in response to the patient's application. This also serves as the final check before imaging.

[0047] 4 is a diagram showing a display example of confirmation information according to the first embodiment. For example, each item of confirmation information to be confirmed before entering an imaging room is displayed superimposed on an image 211 showing a patient who has recognized each item on the display 21 of the information display device 2. Here, it is assumed that the patient has undergone head imaging, is male, and has had surgery on a ligament (no information on bolts, etc.).

[0048] As shown in FIG. 4, the display 21 displays, as a required confirmation item, "Are you able to answer the questions by yourself?" along with a check box (similar below). The display 21 displays, as a confirmation item for bringing in magnetic material, "Are there any pins in your hair?". The display 21 displays, as an implant confirmation item, "Are there any bolts in the area where previous surgery was performed?". Furthermore, the display 21 displays, as a patient application confirmation item, "Are there any other applications from the person undergoing imaging? Yes No."

[0049] The magnetic material inspector will carry out the inspection process in the following steps:

[0050] (1) An image of the patient is displayed on the display 21 of the information display device 2, for example, by holding the camera 26 over the patient.

[0051] (2) Then, if the confirmation is to confirm whether or not the person is wearing earrings, an overlay mark is displayed on the ear, and if the confirmation is to confirm whether or not the person is wearing contact lenses, the mark is displayed on the eye, and the confirmation information items are displayed.

[0052] (3) Display confirmation information items according to the patient's basic information (gender, age, height, weight, blood type, etc.).

[0053] (4) The displayed items are checked through verbal questions and visual inspection.

[0054] (5) To mark items that have been confirmed as checked, leave a history by tapping the check box of the relevant item, etc.

[0055] The display 21 may use AR (Augmented Reality) technology to display an actual image of the user as the image 211 by the camera 26 together with the confirmation information. The display 21 may also display the confirmation information and a virtual human body model as the image 211. In other words, the display control function 243 may cause the display 21 to display an image of the user or a virtual human body model together with the confirmation information.

[0056] By displaying a virtual human body model (i.e., a common virtual image) as the image 211, it is possible to easily add confirmation information that requires attention regardless of the patient. For example, a message encouraging the user to check earrings carefully may be added to the ears of the human body model. By preparing virtual images according to the gender and age (adult, child, etc.) of the patient, the magnetic material checker can check according to the image of the patient that he or she has. The image captured by the camera 26 of the information display device 2 may be displayed on the display 341 of the console 34 of the MRI device 3.

[0057] According to the first embodiment, before a user of the MRI device 3 enters the imaging room, confirmation regarding the bringing in of magnetic materials can be carried out without omission, even by visual inspection or verbal confirmation, and a record of the confirmation can be reliably kept as evidence.

[0058] Second Embodiment Fig. 5 is a block diagram showing a configuration example of an information display system 10 according to the second embodiment. As shown in Fig. 5, the information display system 10 includes an information display device 2, an MRI device 3, and an information retention device 5. The information display device 2, the MRI device 3, and the information retention device 5 are configured to be able to communicate with each other via a network 4. In the following, it is assumed that data transmission and reception between each device is via the network 4, and the phrase "via the network 4" will be omitted when describing data transmission and reception.

[0059] The information display system 10 does not necessarily have to include the MRI device 3. In that case, the information display device 2 and the information holding device 5 are connected via a network 4 so as to be able to communicate with each other.

[0060] The information display device 2 and the MRI apparatus 3 are as described with reference to Fig. 1. The information holding device 5 is a device that holds information on MRI users, and is composed of, for example, a RIS (Radiology Information System) server that holds information on patients. The RIS server, which is an example of the information holding device 5, manages imaging information of patients and manages reservations based on examination orders in cooperation with the MRI apparatus 3. As shown in Fig. 5, the information holding device 5 includes a display 51, an input interface 52, a network interface 53, a processing circuit 54, and a memory circuit 55.

[0061] The display 51 of the information holding device 5 is composed of a general display output device such as a liquid crystal display or an OLED display. The display 51 is an example of a display unit. The input interface 52 is composed of a general input device such as a trackball, a switch button, a mouse, a keyboard, a numeric keypad, and an input circuit that inputs a signal from the input device, and outputs an operation input signal corresponding to an operation by an operator (e.g., an operator of a RIS server, etc.) to the processing circuit 54. The network interface 53 implements various information communication protocols according to the form of the network 4. The network interface 53 connects to the information display device 2 and the MRI device 3 via the network 4 according to the various protocols. The network interface 53 is an example of a transmitting / receiving unit.

[0062] The processing circuitry 54 realizes a function of controlling the information holding device 5. The processing circuitry 54 is also a processor that reads out and executes a program stored in the memory circuitry 55 to hold and manage information about MRI users.

[0063] The memory circuitry 55 has a configuration including a processor-readable recording medium, such as a semiconductor memory element such as a RAM or a flash memory, a hard disk, an optical disk, etc., and stores programs used by the processing circuitry 54, parameter data, information on MRI users, etc. The memory circuitry 55 stores, for example, a patient ID and patient information in association with each other. When the information holding device 5 is a RIS server, the patient information includes information on implants. The memory circuitry 55 is an example of a memory unit.

[0064] Fig. 6 is a sequence chart showing a processing example of the information display system 10 according to the second embodiment. Hereinafter, the processing of the information display device 2 and the information holding device 5 will be described with reference to Fig. 6. Note that the description of the processing of the information display device 2 and the MRI device 3 performed with reference to Fig. 2 will be omitted.

[0065] This process is applied to a patient who is scheduled to be imaged. In this case, the user information is at least one of patient information, which is information about the patient as an MRI user, and imaging conditions adopted for the patient. When the user information includes the patient information, the patient information includes at least one of the patient's image, attributes, belongings, health condition, information about the implant, and an application from the patient. The information about the implant includes, for example, the position, size, compatibility information, model number, etc. of the implant. When the user information includes the imaging conditions, the imaging conditions include at least one of the information about the imaging method, such as the presence or absence of a contrast agent, electrocardiogram synchronization, respiratory synchronization, and the type of imaging sequence, in addition to the imaging site of the patient. The types of imaging sequences include, for example, the SE (Spin-Echo) method, the EPI (Echo Planar Imaging) method, and the SE-EPI method, which is a combination of these methods.

[0066] 2, in the information display device 2, the information acquisition function 241 creates an inquiry for patient information specifying a patient ID unique to the patient. Then, the network interface 23 transmits the inquiry to the information holding device 5. Note that the network interface 23 may transmit the inquiry for patient information to at least one of the MRI device 3 and the information holding device 5.

[0067] In step S21, in the information holding device 5, the network interface 53 receives an inquiry about patient information from the information display device 2.

[0068] In step S22, in the information holding device 5, the processing circuitry 54 extracts the patient ID included in the inquiry, and reads out the patient information associated with the patient ID from the storage circuitry 55. The network interface 53 transmits the read out patient information to the information display device 2.

[0069] 2, in addition to the process of step S4 in the information display device 2, the network interface 23 receives the patient information from the information holding device 5. The processes of steps S5 to S7 are the same as those described in FIG.

[0070] 2, in the information display device 2, the network interface 23 transmits record information in which the confirmation information and the confirmation result are associated with each other to the information holding device 5. The information display device 2 may perform at least one of a process of storing the record information in the memory circuitry 25 and a process of transmitting the record information to the information holding device 5. In other words, the items indicated by the confirmation information and the user's confirmation results for the items are associated with each other and stored in the memory circuitry 55 of the information holding device 5 or the memory circuitry 25 of the information display device 2.

[0071] In step S31, in the information retention device 5, the network interface 53 receives the record information from the information display device 2. Then, the processing circuitry 54 stores the received record information in the storage circuitry 25. As a result, if the information retention device 5 is a RIS server, the fact that magnetic body confirmation of the patient to be imaged has been completed is recorded in the RIS server as evidence.

[0072] According to at least one of the embodiments described above, it is possible to keep magnetic bodies away from the magnetic resonance imaging apparatus.

[0073] The information acquisition function 241 is an example of an acquisition unit, the confirmation generation function 242 is an example of a generation unit, and the display control function 243 is an example of a display control unit.
