Description

  Embodiments described herein relate generally to a magnetic resonance imaging apparatus, a medical image server, and a medical image reference apparatus.

  Some modalities such as a magnetic resonance imaging (MRI) apparatus and a computed tomography (CT) apparatus generate image information in which incidental information is added to image data captured by the modality. The image information has an area for recording image data and an area for recording auxiliary information. As a standard for medical images having an area for recording incidental information, there is a DICOM (Digital Imaging and Communications in Medicine) standard.

  Recently, a medical image management system (PACS: Picture Archiving and Communication System for medical application) that centrally manages image information by a management server has become widespread.

  According to this type of modality and PACS, it is possible to easily classify a plurality of image data on the basis of incidental information, and image readers such as a modality display unit and a remote display unit (PACS viewer) An image based on these classified image data can be interpreted via a medical image reference device (interpretation device).

Japanese Patent Application No. 2006-015125

  By the way, an image acquired by imaging may be classified with additional information added for each type (series) of imaging. In this case, the image acquired by imaging can be classified into different image types for each imaging type.

  Generally, the modality display unit displays images in a list for each image type in the order based on the additional information added for each imaging type (series) of the auxiliary information. However, the order of the image list based on the conventional series information is not necessarily the order in which the radiographer wants to observe the images.

  When a series of examinations configured by a plurality of imaging types (series) is performed, the incidental information includes information indicating the order in which each series was photographed, and the display unit has the same order as this photographing order. Display the image list. However, even if the radiographer plans the shooting order so that the same image list as the desired observation order is generated, the shooting order may be automatically changed as necessary depending on the modality.

  Examples of the case where the imaging order is changed include a case where the workflow is streamlined to shorten the inspection time, and a case where hardware load and SAR (Specific Absorption Rate) are temporally distributed.

  In addition, the timing at which each series of shooting is “performed” at the start of shooting, at the end of shooting, or at the end of image reconstruction differs depending on the manufacturer and version of the modality.

  For this reason, the order of the image list based on the conventional supplementary information is not necessarily the order desired by the interpreter. Therefore, it is necessary for the image interpreter to manually select images sequentially in the order in which he / she wants to view and observe the image list every time the image is interpreted, which is very inconvenient.

  In order to solve the above-described problem, a magnetic resonance imaging apparatus according to an embodiment of the present invention includes an MRI order setting acquisition unit, an imaging control unit, and an MRI data processing order control unit. is there. The MRI order setting acquisition unit acquires order setting information that associates an examination type and an observation order for each image type corresponding to each of a plurality of imaging types executed in the examination of the examination type. The imaging control unit performs imaging of a plurality of imaging types executed in the inspection of the inspection type in a predetermined imaging order, and acquires image data of the plurality of image types. The MRI data processing order control unit causes the display unit to display an image based on the image data acquired by the imaging control unit in the observation order of the image type to which the image data belongs.

  Embodiments of a magnetic resonance imaging apparatus, a medical image server, and a medical image reference apparatus according to the present invention will be described with reference to the accompanying drawings.

(1) First Embodiment (1-1) Schematic Overall Configuration FIG. 1 shows an example of a magnetic resonance imaging apparatus 10, a medical image server 11, and a medical image reference apparatus 12 according to a first embodiment of the present invention. FIG.

  As shown in FIG. 1, a magnetic resonance imaging (MRI) apparatus 10, a medical image server 11, and a medical image reference apparatus (viewer) 12 are connected to each other via a network 1 so that data can be transmitted and received.

  The MRI apparatus 10 includes an imaging unit 16 and an image processing unit 17. The imaging unit 16 is normally installed in an examination room and is configured to generate magnetic resonance signal data related to a patient (subject) P. The image processing device 17 is usually installed in a control room adjacent to the examination room, and is configured to generate and display a reconstructed image from magnetic resonance signal data.

  The imaging unit 16 includes a static magnetic field magnet 21, a gradient magnetic field coil 22, a gradient magnetic field power source 23, a bed 24, a bed control unit 25, a transmission RF coil 26, a transmission unit 27, a reception RF coil 28, and a reception unit 29.

  The static magnetic field magnet 21 is a magnet formed in a hollow cylindrical shape, and generates a uniform static magnetic field in an internal space. For example, a permanent magnet or a superconducting magnet is used as the static magnetic field magnet 21.

  The gradient magnetic field coil 22 is a coil formed in a hollow cylindrical shape, and is disposed inside the static magnetic field magnet 21. The gradient magnetic field coil 22 is formed by combining three coils corresponding to X, Y, and Z axes orthogonal to each other, and these three coils are individually supplied with current from the gradient magnetic field power supply 23. Thus, a gradient magnetic field whose magnetic field intensity changes along the X, Y, and Z axes is generated. The Z-axis direction is the same direction as the static magnetic field.

  Here, the gradient magnetic fields of the X, Y, and Z axes generated by the gradient magnetic field coil 22 correspond to, for example, the slice selection gradient magnetic field Gs, the phase encoding gradient magnetic field Ge, and the readout gradient magnetic field Gr, respectively. . The slice selection gradient magnetic field Gs is used to arbitrarily determine an imaging section. 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 readout gradient magnetic field Gr is used for changing the frequency of the magnetic resonance signal in accordance with the spatial position.

  The gradient magnetic field power source 23 is controlled by the image processing unit 17 and supplies a current to the gradient magnetic field coil 22 according to the pulse sequence execution data.

  The bed 24 includes a top plate 24a on which the subject P is placed. The couch 24 is driven by the couch controller 5, and the top plate 24a is inserted into the cavity (imaging port) of the gradient magnetic field coil 22 with the subject P placed thereon. Usually, the bed 24 is installed such that the longitudinal direction is parallel to the central axis of the static magnetic field magnet 21.

  The couch controller 25 is controlled by the image processor 17 to drive the couch 24 and move the top plate 24a in the longitudinal direction and the vertical direction.

  The transmission RF coil 26 is a coil disposed inside the gradient magnetic field coil 22, and receives a high frequency pulse from the transmission unit 27 to generate a high frequency magnetic field.

  The transmission unit 27 is controlled by the image processing unit 17 and transmits a high-frequency pulse corresponding to the Larmor frequency to the transmission RF coil 26 according to the pulse sequence execution data. The transmission unit 27 includes an oscillation unit, a phase selection unit, a frequency conversion unit, an amplitude modulation unit, a high frequency power amplification unit, and the like. The oscillation unit generates a high-frequency signal having a resonance frequency unique to the target nucleus in the static magnetic field. The phase selector selects the phase of the high frequency signal. The frequency conversion unit converts the frequency of the high-frequency signal output from the phase selection unit. The amplitude modulation unit modulates the amplitude of the high-frequency signal output from the frequency modulation unit according to, for example, a sinc function. The high frequency power amplification unit amplifies the high frequency signal output from the amplitude modulation unit. As a result of the operation of each of these units, the transmission unit 27 transmits a high-frequency pulse corresponding to the Larmor frequency to the transmission RF coil 26.

  The reception RF coil 28 is a coil disposed inside the gradient magnetic field coil 22 and receives a magnetic resonance signal radiated from the subject P due to the influence of the high-frequency magnetic field. The reception RF coil 28 outputs the received magnetic resonance signal to the reception unit 29.

  The reception unit 29 is controlled by the image processing unit 17 and generates magnetic resonance signal data based on the magnetic resonance signal output from the reception RF coil 28 in accordance with the pulse sequence execution data. The receiving unit 29 transmits the generated magnetic resonance signal data to the image processing unit 17.

Controls the input and output of signals sent and received.

  The data collection unit 32 collects magnetic resonance signal data transmitted from the reception unit 29 via the interface unit 31. When collecting the magnetic resonance signal data, the data collection unit 32 stores the collected magnetic resonance signal data in the storage unit 36.

  The input unit 33 is configured by a general input device such as a trackball, a keyboard, a touch panel, and a numeric keypad, and outputs an operation input signal corresponding to a user operation to the MRI control unit 37.

  The display unit 34 is configured by a general display output device such as a liquid crystal display or an OLED (Organic Light Emitting Diode) display, for example, and displays an image showing spectrum data or an image based on magnetic resonance signal data under the control of the main control unit 37. Various images of are displayed.

  The network connection unit 35 implements various information communication protocols according to the form of the network 1. The network connection unit 35 connects the image processing apparatus 17 and other electrical devices (including at least the image server 11) according to these various protocols.

(1-2) Imaging order and observation order In the MRI examination, in general, imaging of a plurality of imaging types is executed in one examination. The imaging order executed by the MRI apparatus 10 is determined by various conditions. Then, the image acquired as a result of imaging is stored in the storage unit 36 together with information indicating the imaging order. However, this imaging order may not match the observation order desired by the image interpreter (image observer such as a doctor).

  First, the imaging sequence executed by the MRI apparatus 10 will be described.

  In MRI, an image that emphasizes one or more parameters such as proton nucleus density, longitudinal relaxation time, transverse relaxation time, flow, diffusion, and chemical shift of tissues and organs is obtained by assembling a pulse sequence describing the data acquisition method. It is possible. In addition to obtaining images of multiple cross-sectional directions in a single examination, it is common to perform diagnostics by characterizing lesions by capturing different types of images of the same cross-section and observing each image in a complementary manner. ing. In the following description, it is assumed that images obtained from imaging of the same imaging type (series) are classified into the same image type.

  The imaging order of the series is classified according to the imaging site, the purpose of diagnosis, and the type of disease, and is stored in advance in the storage unit 36 as order setting information. That is, the order setting information is information in which at least an examination type, a series (imaging type), and an imaging order are associated with each other. The user of the MRI apparatus 10 selects a desired examination type based on the order setting information according to the imaging region and the diagnostic purpose. The MRI apparatus 10 performs imaging of a plurality of series associated with the examination of the selected examination type in the order based on the order setting information.

  The imaging order of a plurality of series is largely determined by the following three conditions.

  The first condition is a condition determined by the convenience of the workflow considering the inspection efficiency.

  FIG. 2 is an explanatory diagram illustrating an example of a part of the order setting information in a case where the imaging order of the imaging types is determined for convenience in workflow considering inspection efficiency.

  Each examination can be classified according to the examination site, for example, the head, the neck, etc. (see the left in FIG. 2). Taking the head as an example, it can be further classified according to examination types such as brain screening and emergency (see the center of FIG. 2). As the examination type, for example, a disease name such as cerebral infarction may be used. Taking the examination type “brain screening” as an example, in the order setting information, six series (imaging types) are associated with one patient, and the imaging time and imaging order of each series are further associated (right in FIG. 2). reference).

  FIG. 2 shows an example of the imaging order of the imaging types determined by the convenience of the workflow considering the inspection efficiency. In the example shown in FIG. 2, each series includes three-dimensional MR angiography (3D MRA), T2-weighted sagittal imaging (T2WSG), T1-weighted axial imaging (T1WAX), and T2-weighted in order from the first in the imaging order. Axial imaging (T2W AX), diffusion weighted axial imaging (DWI), and FLAIR axial imaging (FLAIR AX) are shown.

  In the example shown in FIG. 2, the reason why the three-dimensional MRA is performed first is that the three-dimensional imaging allows easy positioning, and continues during the imaging because the imaging time of this series is long. This is because the positioning of the two-dimensional imaging is performed to shorten the total inspection time. Image data obtained by reconstruction after imaging is stored in the storage unit 36.

  The second condition is a condition determined by the convenience of the MRI apparatus 10.

  The convenience of the MRI apparatus 10 includes temporally dispersing the load of the MRI apparatus and the SAR (Specific Absorption Rate).

  In order to suppress the heat generation of the MRI apparatus 10 due to the high frequency pulse applied to the subject P, it is preferable that the energy (SAR) applied within a certain time and absorbed in the body does not exceed a certain value. The high-frequency power generated by the high-frequency pulse used for imaging differs depending on the series. For example, diffusion-weighted imaging generally uses less high-frequency power than T2-weighted imaging. Therefore, in order to average the high-frequency power within a certain period of time, for example, instead of performing a series with a large SAR twice in succession, the imaging order is determined so that imaging with a low SAR is performed in between. There is a case.

  Further, the gradient coil 22 and the gradient magnetic field power source 23 for generating a gradient magnetic field used for imaging generate heat by applying a pulse current. For this reason, the imaging sequence may be determined so as to distribute and execute imaging with high frequency of generation of gradient magnetic field pulses and imaging with low frequency to suppress the heat generation of the MRI apparatus 10.

  The third condition is a condition determined by the time for the effect of the contrast agent to appear.

  For example, in contrast-enhanced dynamic imaging of the mammary gland, for example, four time phases (four times) are imaged as an early phase in the time (for example, about 1.5 to 2 minutes) from the injection of the contrast agent to the peak of dark staining. In order to see the situation where the contrast agent is washed out, imaging of the delayed phase is started after elapse of, for example, 5 minutes from the injection of the contrast agent. In this case, for example, high-resolution imaging, diffusion-weighted imaging, or the like is performed in the free time of imaging in the early phase and the delayed phase. That is, in order to save useless idle time, the imaging order is determined so that different series of imaging is performed during a series of dynamic imaging.

  In other words, the MRI apparatus 10 may change the imaging order planned by the user based on the first to third conditions.

  In this case, even if the imaging order is planned so as to be the same order as the order in which the radiographer intends to observe, the information on the imaging order added to the images actually captured in each series is assumed to be what the user intended. It may be different.

  Furthermore, at the time of shooting start, at the end of shooting, at the end of image reconstruction, etc., at which time point the shooting of each series is `` performed '', that is, which time point is used to define the shooting order, Different for each modality manufacturer and version.

  For this reason, it is very difficult for a radiogram interpreter to predict the imaging sequence information added to the image data from the imaging sequence planned by himself / herself. Accordingly, the image interpreter displays a list of image data stored in the storage unit 36, for example, selects images in order by looking at information such as the pulse sequence name and series name shown in the list, and the display unit The manual operation of displaying on the screen 34 must be repeated.

  On the other hand, in order to perform a comprehensive diagnosis using images of a plurality of image types, there are cases where an image interpreter desires to always observe all patient data in the same order.

  For example, a radiogram interpreter first observes a T2-weighted image with good contrast, such as a tumor, from which tissue shape information can be obtained, and then observes a T1-weighted image of the same cross section for comparison, After grasping morphological information such as a place, a three-dimensional MRA image is observed in order to see the state of blood vessel running in a suspicious place.

  In contrast, for example, in contrast-enhanced dynamic imaging of the mammary gland, the reader interprets images from the 1st phase to the 4th phase in the early phase followed by the 5th phase image in the delayed phase in order to follow the time course of dark staining. To be observed.

  That is, there is a preferred order of image observation depending on the site, the type of examination, and the suspected disease. Therefore, the MRI apparatus 10 according to the present embodiment is configured so that the imaged image data can be easily changed to the observation order desired by the image interpreter regardless of the imaging order.

  FIG. 3 is an explanatory diagram showing an example of order setting information in which the image observation order is further associated with the examination type, the series, and the imaging order.

  By using the order setting information (see FIG. 3) in which the series and the image observation order are associated in advance, the observation order desired by the interpreter can be easily associated with each image type regardless of the imaging order.

  In the present embodiment, the MRI apparatus 10 adds observation order information indicating the observation order to each image data as supplementary information based on the order setting information. The medical image server 11 and the viewer 12 can display an image based on observation order information added to the image data as supplementary information. This will be described in more detail below.

(1-3) Configurations of MRI Control Unit 37, Server Control Unit 45, and Viewer Control Unit 55 FIG. 4 shows functions of the MRI control unit 37, server control unit 45, and viewer control unit 55 according to the first embodiment. It is a schematic block diagram which shows the structural example of an implementation part. In addition, this function realization part may be comprised by hardware logics, such as a circuit, without using CPU.

  As shown in FIG. 4, the CPU of the MRI control unit 37 functions as at least an MRI order setting acquisition unit 61, an imaging control unit 62, an MRI data processing order control unit 63, and an MRI image data transmission unit 64 according to a program. To do. Each of the units 61 to 64 uses a required work area in the RAM of the MRI control unit 37 as a temporary storage location for data.

  The CPU of the server control unit 45 functions as at least a server image data receiving unit 71, a server data processing order control unit 72, and a server image data transmitting unit 73 by a program. Each of the units 71 to 73 uses a required work area in the RAM of the server control unit 45 as a temporary storage location for data.

The CPU of the viewer control unit 55 functions as at least a viewer image data receiving unit 81 and a viewer data processing order control unit 82 by a program. Each of the units 81 to 82 uses a required work area in the RAM of the viewer control unit 55 as a temporary storage location of data.
First, the MRI control unit 37 will be described.

  The MRI order setting acquisition unit 61 of the MRI control unit 37 acquires the order setting information from the storage unit 36. The order setting information is information in which at least the examination type, a plurality of series executed in the examination of the examination type, the imaging order, and the observation order for each image type corresponding to each of the series are associated (FIG. 3). reference). The MRI order setting acquisition unit 61 gives this order setting information to the imaging control unit 62 and the MRI data processing order control unit 63.

  The imaging control unit 62 controls the imaging unit 16 to perform imaging of a plurality of series executed in the inspection type inspection in the imaging order based on the order setting information. Further, the imaging control unit 62 controls the data collecting unit 32 to store the magnetic resonance signal data obtained by imaging in the storage unit 36. Further, the imaging control unit 62 generates spectrum data and image data of a desired nuclear spin in the subject P by performing reconstruction processing such as Fourier transform on the magnetic resonance signal data stored in the storage unit 36. Then, it is stored in the storage unit 36 again. At this time, the imaging control unit 62 adds inspection type information and series information as supplementary information to each image data. In the present embodiment, series information may not be associated with image data as supplementary information.

  In the following description, the imaging order of the order setting information is an order that takes the above first to third conditions into consideration, and the imaging control unit 62 uses the information (ID) indicating the imaging order as additional information in the image data. In addition, it is assumed that the observation order of the order setting information is associated with the imaging order.

  Note that the imaging order of the order setting information does not consider the above first to third conditions, and the imaging control unit 62 considers the first to third conditions and is different from the imaging order of the order setting information. In the case of executing the imaging, the information (ID) indicating the imaging order that the imaging control unit 62 adds to the image data as supplementary information is different from the imaging order of the order setting information. In this case, the imaging control unit 62 stores the changed imaging order in association with the observation order of the order setting information, and stores information indicating that the imaging order has been forcibly changed, for example, in a required work area of the RAM. It is good to memorize as. This information may be added to the image data as supplementary information. By acquiring the information indicating that the forcible change has been made, the MRI control unit 37, the server control unit 45, and the viewer control unit 55 have forcibly changed the imaging order and the changed imaging order associated with the order setting information. It is understood that should be used.

  Based on the order setting information acquired by the MRI order setting acquisition unit 61, the MRI data processing order control unit 63 adds observation order information indicating the observation order of the image type to which the image data belongs to the image data. Add as Then, the MRI data processing order control unit 63 causes the display unit 34 to display an image based on the image data in the order based on the observation order information added to the image data.

  In the incidental information of the image data compliant with the DICOM standard, information indicating the order of image capturing is added as a series number. However, this series number information is not used in this embodiment. Therefore, the MRI data processing order control unit 63 may add information indicating the observation order to the area to which the series number is added.

When the observation order is set in advance, the comparison with the past image of the same patient and the comparison with the same examination image with another patient can be easily performed. For example, when the screen for displaying an image is divided into two regions on the left and right, and images of two examinations of the same or different patients are displayed on each screen, and the two regions are compared while simultaneously sending images, this embodiment is used. According to the MRI apparatus 10, since the order of displaying different types of images is defined in advance, it is possible to perform image comparison continuously between a plurality of image types (see FIG. 6).
Next, the server control unit 45 will be described.

  The server image data receiving unit 71 of the server control unit 45 receives the image data from the MRI image data transmitting unit 64 via the network 1 and stores the received image data in the storage unit 43 of the own device.
