The present invention relates to a magnetic resonance imaging apparatus capable of

  Conventionally, a magnetic resonance imaging apparatus collects data representing the inside of a subject using a magnetic resonance phenomenon, and images the inside of the subject by reconstructing an image from the collected data. Such a magnetic resonance imaging apparatus performs imaging based on imaging conditions set by an operator. The magnetic resonance imaging apparatus can also perform imaging in synchronization with electrocardiograms, pulses, and respiration according to the type of examination.

  Usually, the magnetic resonance imaging apparatus described above has various functions such as an imaging condition editing function, an image display function, an electric waveform display function, and a collection state display function (see, for example, Patent Document 1 or 2). The operator can check the captured image or observe the imaging state by appropriately using these functions according to the imaging state during the examination.

In the state where imaging has failed, the cause of the failure is confirmed from a log or the like using the collection status display function. In the state during imaging, the radio wave system display function is used to observe synchronous waveforms such as electrocardiogram, pulse, and respiration (when synchronous imaging is performed). In the state before imaging, the imaging parameter editing function is used to change imaging parameters.

  However, in the conventional magnetic resonance imaging apparatus, the various functions described above are generally implemented as independent functions, and the operations required to use each function are different for each function. Therefore, in order to use various functions according to the imaging state, the operator has to perform different operations for each function.

  In general, in an examination using a magnetic resonance imaging apparatus, a plurality of images are continuously performed in units called “series”. In that case, the status of each series varies depending on the progress of the inspection. Therefore, when using the various functions described above in an inspection including a plurality of series, the operator has to perform different operations for each series according to the progress state of the inspection.

  As described above, conventionally, in the examination using the magnetic resonance imaging apparatus, it is necessary to perform complicated operations and judgments in order to use various functions of the magnetic resonance imaging, and the burden on the operator is very large.

A magnetic resonance imaging apparatus for imaging an inside of a subject, wherein a series list display means for displaying a list of series as imaging units in an examination, and at least one series from the list displayed by the series list display means An operation accepting unit that accepts a selection operation for selecting from the operator, an imaging state determining unit that determines an imaging state of a series selected by the selection operation accepted by the operation accepting unit, and the imaging state determining unit. And a function execution means for executing a function associated with the imaging state.

  According to the first aspect of the present invention, it is possible to reduce the burden on the operator by simplifying the operations required when using various functions.

  Exemplary embodiments of a magnetic resonance imaging apparatus according to the present invention will be described below in detail with reference to the accompanying drawings. In the following embodiments, the magnetic resonance imaging apparatus is referred to as “MRI apparatus”.

  First, the overall configuration of the MRI apparatus according to the present embodiment will be described. FIG. 1 is a diagram illustrating an overall configuration of an MRI apparatus 100 according to the present embodiment. As shown in FIG. 1, an MRI apparatus 100 includes a static magnetic field magnet 1, a gradient magnetic field coil 2, a gradient magnetic field power source 3, a bed 4, a bed control unit 5, a transmission RF (Radio Frequency) coil 6, a transmission unit 7, and a reception. RF coil 8, receiving unit 9, sequence control unit 10, and computer system 20 are provided.

  The static magnetic field magnet 1 is formed in a hollow cylindrical shape, and generates a uniform static magnetic field in the internal space. For example, a permanent magnet or a superconducting magnet is used as the static magnetic field magnet 1.

  The gradient coil 2 is formed in a hollow cylindrical shape and is disposed inside the static magnetic field magnet 1. The gradient magnetic field coil 2 is formed by combining three coils corresponding to the X, Y, and Z axes orthogonal to each other. These three coils generate a gradient magnetic field whose magnetic field intensity varies along each of the X, Y, and Z axes by individually receiving a current supply from the gradient magnetic field power supply 3.

  The gradient magnetic fields of the X, Y, and Z axes generated by the gradient coil 2 correspond to, for example, the readout gradient magnetic field Gr, the phase encoding gradient magnetic field Ge, and the slice selection gradient magnetic field Gs. The readout gradient magnetic field Gr is used for changing the frequency of the magnetic resonance signal in accordance with the spatial position. The phase encoding gradient magnetic field Ge is used to change the phase of the magnetic resonance signal in accordance with the spatial position. The slice selection gradient magnetic field Gs is used to arbitrarily determine an imaging section.

  The gradient magnetic field power supply 3 supplies a current to the gradient magnetic field coil 2. The couch 4 includes a couchtop 4a on which the subject P is placed. Under the control of the couch controller 5, the couchtop 4a is placed in the cavity of the gradient magnetic field coil 2 with the subject P placed thereon (imaging). Insert into the mouth). Usually, the bed 4 is installed such that the longitudinal direction is parallel to the central axis of the static magnetic field magnet 1. Under the control of the control unit 26, the bed control unit 5 drives the bed 4 to move the top 4a in the longitudinal direction and the vertical direction.

  The transmission RF coil 6 is disposed inside the gradient magnetic field coil 2 and receives a high frequency pulse from the transmission unit 7 to generate a high frequency magnetic field. The transmission unit 7 transmits a high-frequency pulse corresponding to the Larmor frequency to the transmission RF coil 6.

  The reception RF coil 8 is disposed inside the gradient magnetic field coil 2 and receives a magnetic resonance signal radiated from the subject P under the influence of the high-frequency magnetic field generated by the transmission RF coil 6. The receiving unit 9 generates raw data by digitizing the magnetic resonance signal received by the receiving RF coil 8.

  The sequence control unit 10 scans the subject P by driving the gradient magnetic field power source 3, the transmission unit 7, and the reception unit 9 based on the sequence information transmitted from the computer system 20. Then, when raw data is transmitted from the receiving unit 9 as a result of scanning, the sequence control unit 10 transfers the k-space data to the computer system 20.

  “Sequence information” here refers to the strength of the power supplied from the gradient magnetic field power supply 3 to the gradient magnetic field coil 2 and the timing of supplying the power, the strength of the RF signal transmitted from the transmitter 7 to the RF coil 6, and the RF This is information defining a procedure for performing a scan, such as a signal transmission timing and a timing at which the receiving unit 9 detects a magnetic resonance signal.

  The computer system 20 performs overall control of the MRI apparatus 100, data collection, image reconstruction, and the like. The computer system 20 particularly includes an interface unit 21, a data processing unit 22, a storage unit 23, an input unit 24, a display unit 25, and a control unit 26.

  The interface unit 21 controls input / output of various signals exchanged with the sequence control unit 10. For example, the interface unit 21 transmits sequence information to the sequence control unit 10 and receives raw data from the sequence control unit 10.

  Here, the raw data received by the interface unit 21 includes the slice selection gradient magnetic field Gs generated by the gradient coil 2, the phase encoding gradient magnetic field Ge, and the readout gradient magnetic field Gr in the SE (Slice Encode) direction, PE. The information is stored in the storage unit 23 as k-space data in which spatial frequency information in the (Phase Encode) direction and the RO (Read Out) direction is associated.

  The data processing unit 22 generates spectrum data or image data of a desired nuclear spin in the subject P by performing reconstruction processing such as Fourier transform on the k-space data stored in the storage unit 23.

  The storage unit 23 stores raw data (k-space data) received by the interface unit 21 and image data generated by the data processing unit 22 for each subject P.

  The input unit 24 receives various instructions and information input from the operator. As the input unit 24, a pointing device such as a mouse or a trackball, a selection device such as a mode change switch, or an input device such as a keyboard is appropriately used.

  The display unit 25 displays various types of information such as spectrum data or image data under the control of the control unit 26. As the display unit 25, a display device such as a liquid crystal display is appropriately used.

  The control unit 26 includes a CPU (Central Processing Unit), a memory, and the like (not shown), and performs overall control of the MRI apparatus 100. For example, the control unit 26 generates sequence information based on imaging conditions input from the operator via the input unit 24 and transmits the generated sequence information to the sequence control unit 10 to scan the subject P. Is executed. The control unit 26 controls image reconstruction performed by the data processing unit 22. In addition, the control unit 26 controls the bed control unit 5 through the interface unit 21 in response to an instruction input from the operator through the input unit 24.

  The overall configuration of the MRI apparatus 100 according to the present embodiment has been described above. With this configuration, in the present embodiment, the control unit 26 causes the display unit 25 to display a list of series that are units of imaging in the examination, and includes the list displayed via the input unit 24. A selection operation for selecting at least one series from the operator is received from the operator. And the control part 26 determines the imaging state of the series selected by selection operation, and performs the function matched with the determined imaging state.

  As a result, even if the imaging status of the series differs depending on the progress of the inspection, the operator simply performs the same operation of selecting a series from the list, and the target function corresponding to the imaging status is obtained for each series. Be able to run. That is, according to the MRI apparatus 100 according to the first embodiment, it is possible to reduce the burden on the operator by simplifying the operations necessary when using various functions.

  Hereinafter, the functions of the MRI apparatus 100 described above will be described in detail with a focus on functions related to the control unit 26. First, the configuration of the storage unit 23 and the control unit 26 illustrated in FIG. 1 will be described. FIG. 2 is a functional block diagram illustrating configurations of the storage unit 23 and the control unit 26 illustrated in FIG. 1. As shown in FIG. 2, the storage unit 23 particularly includes a series list storage unit 23a, a function information storage unit 23b, an image data storage unit 23c, an imaging condition storage unit 23d, and a log storage unit 23e.

  The series list storage unit 23a stores, for each series, information indicating the imaging state of the series that is a unit of imaging in the examination. Specifically, the series list storage unit 23a stores information in which a series number indicating the order of series in the examination is associated with a status indicating the imaging state of each series. FIG. 3 is a diagram illustrating an example of information stored in the series list storage unit 23a.

  As illustrated in FIG. 3, for example, the series list storage unit 23 a stores “Done”, “Failed”, “Current”, and “Wait” as the status for each series. Here, “Done” indicates a state where imaging has been completed, and “Failed” indicates a state where imaging has failed. Further, “Current” indicates a state during imaging, and “Wait” indicates a state before imaging.

  The information stored in the series list storage unit 23a is updated to the latest state for each series at any time by the series list update unit 26a described later while the inspection is being performed.

  Returning to FIG. 2, the function information storage unit 23 b stores information indicating functions used according to the imaging state. Specifically, the function information storage unit 23b stores information in which the status indicating the imaging state is associated with the function of the MRI apparatus 100. FIG. 4 is a diagram illustrating an example of information stored in the function information storage unit 23b.

  As illustrated in FIG. 4, for example, the function information storage unit 23 b stores “Done” indicating a state where imaging has been completed and an image display function in association with each other, and logs “Failed” indicating a state where imaging has failed. The display function is stored in association with each other. Further, the function information storage unit 23b stores “Current” indicating the state during imaging and the reference information display function in association with each other, and associates “Wait” indicating the state before imaging and the imaging condition editing function in association with each other. Remember.

  Information stored by the function information storage unit 23b may be registered by a maintenance staff when the MRI apparatus 100 is installed in a hospital or the like, or may be registered by an operator after the MRIR apparatus 100 is installed. It is good. In any case, the person in charge of information registration registers in advance functions that are likely to be used by the operator for each imaging state.

  Returning to FIG. 2, the image data storage unit 23 c stores the image data reconstructed by the data processing unit 22.

  The imaging condition storage unit 23d stores, for each series, imaging conditions set in advance by the operator when an inspection is performed. Specifically, the imaging condition storage unit 23d stores a plurality of types of imaging parameters as imaging conditions. For example, the imaging condition storage unit 23d stores the type of imaging as one of imaging parameters. The “type of imaging” here is, for example, synchronous imaging, shimming imaging, motion compensation imaging, dynamic imaging, bed movement imaging, or the like.

The imaging condition storage unit 23d also stores the type of post-processing set by the operator along with the imaging conditions, the type of image to be captured, and the like. Here, “post-processing” is processing performed after an image is reconstructed, and “type of post-processing” is, for example, MIP (Maximum Intensity Projection) processing, dynamic difference processing, filming, etc. is there. Further, the "type of an image to be captured", for example, T ₁ weighted images and T ₂ weighted images, diffusion weighted image, and the like dynamic image.

  The log storage unit 23e stores various logs related to the operation of the MRI apparatus 100. For example, the log storage unit 23e is, for example, information that is output when the hardware state (for example, a state such as temperature or load) of the MRI apparatus 100 changes, or a failure that is output when imaging fails. Various information such as information indicating the cause of the error is stored as a log.

  On the other hand, the control unit 26 particularly includes a series list update unit 26a, a series list display unit 26b, an operation reception unit 26c, an imaging state determination unit 26d, and a function execution unit 26e.

  The series list update unit 26a updates the information stored in the series list storage unit 23a to the latest state as needed for each series while the inspection is being performed.

  The series list display unit 26b causes the display unit 25 to display a list of series (hereinafter referred to as “series list”) that is a unit of imaging in the examination. Here, the “series list” is a list in which statuses indicating imaging states are listed for each status under examination (see, for example, FIG. 6). Specifically, the series list display unit 26b acquires information indicating an imaging state for each series from the series list storage unit 23a at a predetermined cycle during the inspection, and displays the series list on the display unit 25 based on the acquired information. Display.

  The operation receiving unit 26 c receives various instructions and information input from the operator via the input unit 24. For example, the operation receiving unit 26c receives from the operator a selection operation for selecting at least one series from the series list displayed on the display unit 25 by the series list display unit 26b.

  The imaging state determination unit 26d determines the imaging state of the series selected by the selection operation received by the operation reception unit 26c. Specifically, when a selection operation for selecting a series is received by the operation reception unit 26c, the imaging state determination unit 26d is selected based on information (see FIG. 3) stored in the series list storage unit 23a. Determine the status of the selected series.

  For example, it is assumed that the information shown in FIG. 3 is stored in the series list storage unit 23a. In this case, when the series whose series number is “1” is selected by the operator, the imaging state determination unit 26d determines that the status of the series is “Done” (a state where imaging has been completed). Further, for example, when the series with the series number “4” is selected by the operator, it is determined that the status of the series is “Wait” (state before imaging).

  The function execution unit 26e executes a function associated with the imaging state determined by the imaging state determination unit 26d. Specifically, when the status of the series is determined by the imaging state determination unit 26d, the function execution unit 26e determines the status determined based on the information (see FIG. 4) stored in the function information storage unit 23b. The function associated with is identified. Then, the function execution unit 26e executes the specified function. The execution of various functions by the function execution unit 26e will be described in detail later.

  Next, procedures for executing various functions in the MRI apparatus 100 according to the present embodiment will be described. FIG. 5 is a flowchart illustrating an execution procedure of various functions in the MRI apparatus 100 according to the present embodiment.

  As shown in FIG. 5, in the MRI apparatus 100, when the inspection is started by the operator (step S101, Yes), the series list display unit 26b first displays the series list on the display unit 25 (step S102). . FIG. 6 is a diagram illustrating an example of a series list displayed by the series list display unit 26b.

  As shown in FIG. 6, for example, the series list display unit 26b displays the series number and status acquired from the series list storage unit 23a side by side on the left side of the display area of the display unit 25. The example of FIG. 6 shows a series list when the information shown in FIG. 3 is stored in the series list storage unit 23a. In the example of FIG. 6, the area on the right side of the series list is a display area for displaying various information according to the imaging state.

  Returning to FIG. 5, when the operation receiving unit 26 c receives a selection operation for selecting a series from the series list displayed on the display unit 25 from the operator (Yes in step S <b> 103), the imaging state determination unit 26 d The status of the series selected by the operator is determined (step S104).

  When the imaging state determination unit 26d determines that the status is “Wait” (step S105, Yes), the function execution unit 26e executes the imaging condition editing function (step S106). Here, the “imaging condition editing function” is a function that accepts changes in various imaging parameters from the operator and reflects the accepted changes in the imaging condition storage unit 23d described above. FIG. 7 is a diagram illustrating an example of an imaging condition editing screen by the imaging condition editing function.

  As shown in FIG. 7, for example, when a series whose status is “Wait” is selected by the operator, the function execution unit 26e displays an imaging condition editing screen for changing various imaging parameters on the right side of the series list. And accepts parameter changes related to the selected series.

  Returning to FIG. 5, when it is determined that the status is “Current” (step S107, Yes), the function execution unit 26e executes the reference information display function (step S108). Here, the “reference information display function” is a function for displaying various types of information related to the imaging being performed. The reference information display function will be described in detail later.

  If it is determined that the status is “Failed” (step S109, Yes), the function execution unit 26e executes the log display function (step S110). The “log display function” here refers to the log stored in the log storage unit 23e, acquires information indicating the cause of the imaging failure of the series selected by the operator, and displays the information in the display unit 25. It is a function to display.

  At this time, instead of displaying the information acquired from the log, the function execution unit 26e executes, for example, a process related to maintenance based on the log stored in the log storage unit 23e or a serviceman (maintenance). Notification) may be executed. Alternatively, for example, an instruction for preventing failure may be displayed. Alternatively, re-imaging may be performed by further displaying a button for receiving a re-imaging instruction. FIG. 8 is a diagram illustrating an example of processing related to maintenance.

  As illustrated in FIG. 8, for example, when a series whose status is “Failed” is selected by the operator, the function execution unit 26 e displays maintenance information related to the selected series on the right side of the series list. In the example of FIG. 8, “Action” is information for an operator who is imaging, and “Cause” is information for a serviceman (maintenance worker).

  Returning to FIG. 5, when it is determined that the status is “Done” (step S111, Yes), the function executing unit 26e executes the image display function (step S112). Here, the “image display function” is a function for displaying an image captured by the MRI apparatus 100. FIG. 9 is a diagram illustrating an example of image display by the image display function.

  As illustrated in FIG. 9, for example, when a series whose status is “Done” is selected by the operator, the function execution unit 26e displays an image captured in the selected series on the right side of the series list. . In addition, although the example of FIG. 9 shows the case where only one image is displayed, a plurality of images may be displayed.

  Various image processing may be performed on the image displayed by the image display function. In that case, the function execution unit 26e appropriately controls the data processing unit 22 and the like, and performs brightness adjustment, filter processing, MIP (Maximum Intensity Projection) processing, and other devices on the images captured in the selected series. Post-processing such as transfer processing to an image storage server (for example, an image storage server) or filming for transferring an image to a film is performed.

  As described above, in the MRI apparatus 100 according to the present embodiment, the function to be executed varies depending on the imaging state of the series selected by the operator. That is, the behavior of the apparatus changes according to the imaging state of the series selected by the operator.

  Next, a processing procedure of the reference information display function shown in FIG. 5 will be described. FIG. 10 is a flowchart showing a processing procedure of the reference information display function shown in FIG. As shown in FIG. 10, as a reference information display function, the function execution unit 26e first refers to the imaging condition storage unit 23d and confirms the imaging conditions of the series selected by the operator (step S201).

  Subsequently, the function execution unit 26e executes various functions according to the confirmed imaging conditions. Specifically, the function execution unit 26e confirms the type of imaging included in the imaging condition, and when the type of imaging is “synchronous imaging” (Yes in step S202), the function executing unit 26e is used for the imaging being performed. The acquired synchronization signal is acquired, and a synchronization waveform indicating the waveform of the acquired synchronization signal is displayed on the display unit 25 (step S203). FIG. 11 is a diagram showing an example of the display of the synchronous waveform by the reference information display function, and shows a case where the electrocardiographic synchronous waveform is displayed.

  As illustrated in FIG. 11, for example, when a series whose status is “Current” is selected by the operator, for example, the function execution unit 26e displays a synchronized waveform such as an electrocardiogram, a pulse, and a breath on the right side of the series list. To display. For example, the function execution unit 26e may display the waveform of the RF signal.

  Returning to FIG. 5, when the type of imaging is “shimming imaging” (step S204, Yes), the function execution unit 26e detects the center frequency (f0) of the magnetic field after the shimming is performed. The detected center frequency is displayed (step S205).

  If the type of imaging is “motion compensated imaging” (step S206, Yes), the function execution unit 26e displays a diaphragm state waveform based on an echo signal indicating the movement of the diaphragm (step S206). S207).

  If the type of imaging is “dynamic imaging” (step S208, Yes), the function execution unit 26e displays the images captured over time by dynamic imaging in order of imaging, thereby displaying dynamic imaging. Is displayed (step S209).

  In addition, when the type of imaging is “couch moving imaging” (step S210, Yes), the function execution unit 26e acquires the movement amount of the top 4a from the bed control unit 5, and sets the acquired movement amount. Based on this, the couch position status indicating the position of the top 4a is displayed (step S211).

  As described above, in the MRI apparatus 100 according to the present embodiment, the function to be executed is changed according to the imaging condition of the series selected by the operator. Here, the case where the function to be executed is changed according to the type of imaging has been described. However, the function is executed according to other imaging parameters such as the type of imaging region and the number of images to be captured. The function may be changed.

  As described above, in this embodiment, the series list display unit 26b causes the display unit 25 to display a series list that is a list of series that is a unit of imaging in the examination, and the operation reception unit 26c displays the displayed series. A selection operation for selecting at least one series from the list is received from the operator. Then, the imaging state determination unit 26d determines the imaging state of the series selected by the accepted selection operation, and the function execution unit 26e executes a function associated with the determined imaging state.

  With this configuration, the operator can perform a target process corresponding to the state of each series only by performing the same operation of selecting a series from the series list. Further, the operator does not need to learn complicated operations. Therefore, according to the present embodiment, it is possible to reduce the burden on the operator by simplifying operations required when using various functions.

  In the present embodiment, when the function execution unit 26e executes the function, the function to be executed is changed according to the imaging condition set when the inspection is performed. Therefore, the function corresponding to the imaging condition is automatically set. Therefore, the burden on the operator can be further reduced.

  As mentioned above, although the Example of this invention was described, this invention may be implemented with a various different form other than the Example mentioned above.

  For example, the function execution unit 26e may change the function to be executed according to the type of post-processing set when the inspection is performed. In this case, for example, when a series whose status is “Done” is selected by the operator, the function execution unit 26e is included in the imaging conditions of the selected series with reference to the imaging condition storage unit 23d. Check the type of post-processing.

  For example, when the type of post-processing is MIP processing, the function execution unit 26e displays a parameter input screen for accepting input of parameters necessary for performing MIP processing from the operator. To display. Thereafter, when a parameter is input by the operator, the function execution unit 26e controls the data processing unit 22 to perform MIP processing based on the input parameter.

  In this way, the function execution unit 26e changes the function to be executed in accordance with the type of post-processing set when the inspection is performed, for example, the post-processing performed on the captured image. When the functions available to the operator are limited for each type, the operator is not required to perform unnecessary operations, and the burden on the operator can be further reduced.

  Alternatively, the function execution unit 26e may change the function to be executed according to the type of image captured in the examination. In this case, for example, when the function execution unit 26e selects a series whose status is “Done” by the operator, the type of image captured in the selected series with reference to the imaging condition storage unit 23d Confirm.

  Then, for example, the function execution unit 26e selects what can be performed on the confirmed type of image from the post-processing that can be executed by the data processing unit 22, and displays a list of the selected post-processing on the display unit 25. To do. Thereafter, when an operation for selecting a post-process from the displayed list is performed by the operator, the function execution unit 26e controls the data processing unit 22 to execute the selected post-process.

  As described above, the function execution unit 26e changes the function to be executed in accordance with the type of the image to be captured in the examination, thereby limiting the functions available to the operator for each type of image to be captured, for example. In such a case, the operator is not required to perform an unnecessary operation, so that the burden on the operator can be further reduced.

  Alternatively, the function execution unit 26e may change the function to be executed according to the operator. In this case, for example, when the function execution unit 26e displays the maintenance information shown in FIG. 8, the operator's attribute is confirmed by the user ID input when using the MRI apparatus 100, and the operator If the photographer is a photographer, only “action” information is displayed on the display unit 25, and if the operator is a serviceman, only “cause” information is displayed on the display unit 25.

  As described above, the function execution unit 26e does not cause the operator to perform an unnecessary operation when the function to be used is different for each operator by changing the function to be executed according to the operator. Therefore, the burden on the operator can be further reduced. Moreover, an appropriate function can be provided for each operator.

  As described above, the magnetic resonance imaging apparatus according to the present invention is useful when various functions such as an imaging condition editing function, an image display function, an electric waveform display function, and a collection state display function are provided. It is suitable for cases where it is required to reduce the burden on the operator by simplifying the operations required for use.
