Description

The present invention relates to a biological information measuring device.

When examining the cardiac function of a subject, a biomagnetic measuring device that measures the weak biomagnetism generated from the heart or the like has a function of detecting the magnetism generated by the weak electric current accompanying the excitement of the cells constituting these organs. This is an important technique for diagnosing heart diseases and neurological diseases.

Therefore, an image diagnostic device using an X-ray irradiation device at a place different from the biological information measurement device (for example, as described in Patent Document 1, X-ray irradiation used with the subject lying on its back). The morphological image by the device) may be superimposed.

JP-A-2009-172175

However, there is a problem that the measurement results cannot be accurately matched because the subject moves between the diagnostic imaging apparatus (X-ray irradiation apparatus or the like) and the biological information measuring apparatus. For example, as the subject moves between the X-ray irradiation device and the biomagnetic measuring device, the subject's trunk (spine) bends or warps in the anterior-posterior or lateral direction, or the joints of the subject's limbs bend. Since it stretches and stretches, it is extremely difficult to accurately match the position information of the subject by the diagnostic imaging apparatus with the position of the subject at the time of inspection by the biomagnetic measuring apparatus.

Therefore, the present inventors have stated that by arranging a magnetic sensor on the back side of the X-ray film (the side opposite to the subject) when taking a chest X-ray, it is possible to simultaneously perform a cardiac function test. I found it. In this way, by measuring the cardiac function corresponding to the morphology of the heart as magnetic data, it is possible to perform a comprehensive examination of the heart at the same time as the examination of the lungs.

However, as described in Patent Document 1, if the subject is in a recumbent position (lying in the horizontal direction) at the time of imaging, there is a problem that pleural effusion, which is a diagnostic item of chest X-ray, cannot be diagnosed.

On the other hand, when the standing position measurement is used, the subject may be staggered and cannot be measured stably, or the subject may be in a situation where it is difficult to take a standing position.

The present invention has been made in view of the above circumstances, and provides a biomagnetic measuring device capable of stably performing image diagnosis and biomagnetic measurement at the same time and diagnosing pleural effusion. The purpose.

As described above, the present inventors have found that by arranging a magnetic sensor on the back side of the X-ray irradiation device when photographing a chest X-ray, it is possible to perform image diagnosis and biomagnetic measurement at the same time. Furthermore, the present inventors have found that pleural effusion can be diagnosed and measured by taking an oblique posture when performing image diagnosis and biomagnetic measurement at the same time, and complete the present invention. I arrived. More specifically, it is an object of the present invention to provide the following.

It is a block diagram which shows the structure of the biological information measuring apparatus which concerns on this embodiment. It is sectional drawing which shows the structure of the biomagnetic detection part. It is a figure which shows the measurement result which superposed the biomagnetic measurement result and the X-ray image.

Hereinafter, embodiments of the present invention will be described in detail, but the present invention is not limited to the following embodiments, and can be carried out with appropriate modifications within the scope of the object of the present invention. ..

<Biological information measuring device>
FIG. 1 is a configuration diagram showing a configuration of a biological information measuring device 1 according to the present embodiment. As shown in FIG. 1, the bioinformation measuring device 1 according to the present embodiment supports a biomagnetic detection unit 2 having a magnetic sensor capable of detecting the biomagnetism of the subject S and a biomagnetism detection unit 2, and also supports the biomagnetism detection unit 2. The subject S includes a support portion 3 having a support surface 3a capable of taking an oblique position. In the present invention, the "oblique position" means neither a standing position nor a lying position (prone position / supine position). Further, the "support portion 3" includes a mode of supporting the entire subject S and a mode of supporting a part (measurement region) of the subject S. Further, the "support portion 3" includes a mode in which the angle of the support surface 3a from the horizontal direction is fixed to an arbitrary angle and a mode in which the angle of the support surface 3a from the horizontal direction can be displaced to an arbitrary angle. ..

Further, the biometric information measuring device 1 is provided between the subject S and the biomagnetic detection unit 2 and includes a radiation detection unit 4 capable of detecting the irradiated radiation.

Further, the biological information measuring device 1 further includes an irradiation unit 5 that irradiates the subject S with radiation.

Hereinafter, the biomagnetic detection unit 2, the support unit 3, the radiation detection unit 4, and the radiation irradiation unit 5 will be described.

[Biomagnetic detector]
The biomagnetic detection unit 2 is composed of a plurality of magnetic sensors 2a for detecting biomagnetism and a holding unit 2b for holding the magnetic sensor 2a. The holding portion 2b is formed in a size corresponding to a predetermined measurement region of the subject, and a plurality of magnetic sensors 2a are arranged in an array (for example, 5 × 8) on a plane facing the subject. By having a plurality of magnetic sensors 2a, it is possible to obtain a large amount of biomagnetic information, and it is possible to obtain more detailed biomagnetic information. The arrangement direction and number of the magnetic sensors 2a included in the biomagnetic detection unit 2 are not particularly limited, and may be appropriately set according to the measurement area and resolution of the subject S.

The holding portion 2b is preferably made of a non-magnetic material. Since the holding portion 2 is made of a non-magnetic material, even if the holding portion 2b vibrates, it is possible to suppress the influence of the fluctuation of the environmental magnetism on the magnetic sensor 2a. Examples of the non-magnetic material include plastic materials such as acrylic resin and non-ferrous metals such as copper and brass.

The biomagnetic detection unit 2 may be fixed to the support unit 3 so as to be installed at a location corresponding to the measurement region of the subject S, or the support unit 3 is shorter than the support unit 3 in FIG. It may be configured to be slidable in the X direction, which is the manual direction, and / or the Y direction, which is the longitudinal direction. Since the biomagnetic detection unit 2 is configured to be slidable in the X direction and / or the Y direction with respect to the support unit 3, the biomagnetism detection unit 2 can move to a location corresponding to the measurement region of the subject S. Convenience is improved. Further, since the biomagnetic detection unit 2 is configured to be slidable with respect to the support unit 3, the biomagnetism detection unit 2 can be miniaturized and the cost can be reduced. The movement of the biomagnetic detection unit 2 may be performed manually or automatically.

(Magnetic sensor)
The magnetic sensor 2a detects the biomagnetism generated by the subject. Specifically, as the magnetic sensor 2a, a giant magnetoresistive sensor (GMR sensor), a tunnel magnetoresistive sensor (TMR sensor), an anisotropic magnetoresistive sensor (AMR sensor), a magnetic impedance sensor (MI sensor), and a fluxgate Examples include sensors. The magnetic sensor 2a used in this embodiment may be any magnetic sensor as long as it can detect a magnetic field of about ^{10 -4} T (tesla) to ^{10-15 T (tesla).} The magnetic sensor 2a used in the present embodiment can obtain the same level of information as the SQUID sensor, and unlike the SQUID sensor, it does not need to install a temperature control mechanism such as a cooling container and is easy to handle. Easy to get close to.

The magnetic sensing direction of the magnetic sensor 2a is the magnetism of the biomagnetic detection unit 2 when the support surface 3a of the support portion 3 forms an XY plane and the normal direction of the support surface 3a is the Z direction in the XYZ orthogonal coordinate space. The magnetic sensing direction of the sensor 2a is preferably parallel to at least one of the X direction, the Y direction, and the Z direction. By making the magnetic sensing direction of the magnetic sensor 2a parallel to at least one of the X, Y, and Z directions, it is possible to accurately estimate the magnetic field source and / or the current source from the measurement data. In addition, the biomagnetic detection unit 2 can generate more accurate biomagnetic information by obtaining biomagnetic information obtained from at least two or more magnetically sensitive directions in the XYZ Cartesian coordinate space. The magnetic sensing directions of the plurality of magnetic sensors 2a may be the same or different. Further, one magnetic sensor 2a may have a plurality of magnetic sensing directions.

The detection signal detected by the magnetic sensor 2a is sent to a calculation unit (not shown). The calculation unit generates biomagnetic information from the signal detected by the magnetic sensor 2a, converts it into image information, and displays and outputs it to the display device.

The magnetic sensor 2a may be fixed to the holding portion 2b or may be detachably configured. The number and arrangement of the magnetic sensors 2a can be adjusted according to the shape and size of the measurement region of the subject S (for example, children, adults, animals other than humans, etc.). In addition, the required spatial resolution may differ depending on the measurement location of the subject S. Even in such a case, since the magnetic sensor 2a can be attached to and detached from the holding portion 2b, the magnetic sensor 2a is densely arranged in a place where high spatial resolution is required (for example, the heart). The magnetic sensors 2a can be sparsely arranged in places where high spatial resolution is not required. Further, since the magnetic sensor 2a can be attached to and detached from the holding portion 2b, it is not necessary to install an unnecessary magnetic sensor 2a, and signals are not exchanged or supplied to the unnecessary magnetic sensor 2a to save power. It is possible to reduce the cost and the cost.

Further, the magnetic sensor 2a may or may not have wiring for sending and receiving signals and supplying electric power. However, as shown in FIG. 2, in the biomagnetic measuring device 1, since a plurality of magnetic sensors 2a are arranged, it is preferable to have wiring in order to avoid crosstalk.

FIG. 2 is a schematic cross-sectional view showing the configuration of the biomagnetic detection unit. For example, as shown in FIG. 2, the holding unit 2b of the biomagnetic detection unit 2 has a plurality of insertion holes 2c into which the magnetic sensor 2a can be inserted, and a plurality of insertion holes 2c in which the detection surface of the magnetic sensor 2a can be fixed at a predetermined position. A frame 2d (a fixture may be used if necessary) is formed. As a result, the magnetic sensor 2a is detachably configured with respect to the holding portion 2b at a desired location. Further, the magnetic sensor 2a may have the wiring 2e.

[Support]
The support portion 3 has a support surface 3a capable of allowing the subject S to take an oblique posture. Specifically, the angle of the support surface 3a of the support portion 3 is preferably about 30 ° to 60 ° from the horizontal direction.

Since the subject S is in an oblique position on the support portion 3 at the time of measurement, the position is stable and the detection surface of the biomagnetic detection unit 2 arranged on a part of the support surface 3a is affected by the action of gravity. It will be in close contact. Therefore, the biomagnetism detection unit 2 increases the strength of the biomagnetism that can be detected from the subject S. Further, since the subject S is in an oblique position, even if pleural effusion is accumulated in the lungs, it can be easily detected by the radiation detection unit 4 described later, and pleural effusion can be diagnosed. When the support surface 3a of the support portion 3 is in the horizontal direction, the position of the subject S is stable and the subject S can be brought into close contact with the biomagnetic detection portion 2, but the diagnosis of pleural effusion becomes difficult.

The support portion 3 may have a configuration in which the inclination of the support surface 3a is fixed in advance at an arbitrary angle, but the support portion 3 may be provided with an angle adjusting mechanism capable of adjusting the inclination of the support surface to an arbitrary angle. ..

For example, the support portion 3 shown in FIG. 1 has an arbitrary inclination of the support surface 3a by an angle adjusting mechanism 6 including a pedestal 6a and a semicircular rotary shaft support frame 6b rotatably supported by the pedestal 6a. It may be adjusted to an angle. According to the angle adjusting mechanism 6, the rotating shaft support frame 6b is rotated in the counterclockwise direction in the drawing by a driving means (not shown), so that the support portion 3 is rotated in the counterclockwise direction in the drawing around the rotating shaft supporting frame 6b. Rotates to increase the inclination of the support surface 3a from the horizontal direction. On the other hand, when the rotating shaft support frame 6b is rotated in the clockwise direction in the drawing by a driving means (not shown), the support portion 3 is rotated in the clockwise direction in the drawing around the rotating shaft support frame 6b, and the support surface 3a is horizontal. The inclination from the direction becomes small.
[Radiation detector]
The radiation detection unit 4 is arranged between the subject S and the biomagnetic detection unit 2. When protruding from the support surface 3a, the subject S feels uncomfortable. Therefore, it is preferable that the surface of the radiation detection unit 4 facing the subject S is in the same plane as the support surface 3a.

Further, the radiation detection unit 4 is preferably non-magnetic. If the radiation detection unit 4 has magnetism, the magnetism generated by the radiation detection unit 4 may adversely affect the detection accuracy of the biomagnetism detection unit 2, which is not preferable.

Examples of the radiation detection unit 4 include a radiation film, an imaging plate, a flat panel detector (hereinafter referred to as FPD), and the like. The imaging plate is a photoconductor capable of converting an image (analog image data) obtained by irradiation with radiation into digital image data. Unlike radiation film, imaging plates have become popular in recent years because they are reusable. The FPD is efficient because it can acquire radiation as a morphological image which is digital image data and does not require a step of converting analog image data into a digital image. The signal detected by the FPD is sent to a calculation unit (not shown). The calculation unit generates a morphological image from the signal detected by the FPD, converts it into image information, and displays and outputs it to the display device.

By the way, since the magnetism emitted by the subject S is weak, if the magnetic radiation detection unit 4 is arranged between the biomagnetic detection unit 2 and the subject S, the detection result by the biomagnetic detection unit 2 will be obtained. It has a big impact. Therefore, the radiation detection unit 4 is composed of components that do not significantly affect the detection accuracy of the biomagnetic detection unit 2.

For example, when the radiation detection unit 4 is a radiation film or an imaging plate, it is generally housed in a cassette made of metal, but the magnetism of the cassette adversely affects the detection result of the biomagnetic detection unit 2. It ends up. Therefore, it is preferable to use a cassette made of a non-magnetic material or one that is not housed in a cassette made of metal.

In order to accurately superimpose the detection result of the biomagnetic detection unit 2 and the detection result (morphological image) of the radiation detection unit 4, a magnetic marker that generates a predetermined magnetic field is arranged in the radiation detection unit 4. You may. Here, the magnetic marker does not interfere with the acquisition of image information of the radiation detection unit 4, and is arranged within the detection range of the biomagnetic detection unit 2 (for example, the edge portion of the holding unit 2b). When the radiation detection unit 4 is housed in the cassette, the magnetic marker may be arranged on the surface of the cassette.

Conventionally known magnetic markers can be used, and examples thereof include a seal of a small coil called a marker coil. The marker coil is energized to generate a weak magnetic field, and the biomagnetic detection unit 2 detects the magnetic field generated by the marker coil. Then, the position calculation unit (not shown) of the biomagnetism detection unit 2 calculates the position where the magnetic field is generated by the marker coil, so that the detection result of the biomagnetism detection unit 2 and the detection result of the radiation detection unit 4 (not shown). It can be used as an index when superimposing the morphological image).

The number of magnetic markers is not particularly limited as long as there are a plurality of magnetic markers. In order to improve the accuracy of grasping the shape of the measurement target, it is preferable that the number of magnetic markers is large, the noise caused by the magnetic markers is suppressed to a small value, and the magnetism from the subject S can be accurately detected by the biomagnetic detection unit. The number of magnetic markers is preferably small. Considering both, the number of magnetic markers is preferably 2 or more and 6 or less, and more preferably 2 or more and 4 or less.

Further, a flat panel detector (hereinafter referred to as FPD) is preferable for the radiation detection unit 4.

The FPD has a so-called direct conversion method in which an electric charge is generated by a detection element according to the dose of the irradiated radiation and converted into an electric signal, and the irradiated radiation is converted into electromagnetic waves of other wavelengths such as visible light by a scintillator or the like. After conversion, there is a so-called indirect method in which an electric charge is generated by a photoelectric conversion element such as a photodiode according to the energy of the converted and irradiated electromagnetic waves and converted into an electric signal. Generally, in an FPD, various parts that perform these steps are built in a housing such as a cassette. However, as described above, since it is not preferable that the radiation detection unit 4 is magnetic, the FPD used in the radiation detection unit 4 of the present invention can be arranged outside among these various parts. , Various parts such as a circuit board having a plurality of magnetic materials, a control board, and a battery are removed from the radiation detection unit 4 and arranged outside. Further, conventionally, parts such as cassettes made of metal or the like are made of non-magnetic materials or are not used. As described above, it is preferable that the radiation detection unit 4 does not significantly affect the detection accuracy of the biomagnetic detection unit 2 due to the disassembly of the component parts of the FPD, the change of the component material, or the like. Further, since it is preferable that the subject S and the biomagnetic detection unit 2 are as close as possible to each other, a component that can be arranged outside is removed from the radiation detection unit 4 and its thickness (direction orthogonal to the subject S) is set. It should be as thin as possible. For example, the thickness of the FPD is preferably 10 mm or less, more preferably 6 mm or less.

Further, from the viewpoint of reducing the influence of the radiation detection unit 4 (FPD) on the detection accuracy of the biomagnetism detection unit 2, the radiation detection unit 4 (FPD) is used while the biomagnetism detection unit 2 is detecting the biomagnetism. , It is preferable that the radiation detection unit 4 (FPD) is provided with a control unit that can be controlled so as not to supply power. This is because when power is supplied to the radiation detection unit 4 (FPD), an electric charge is generated in the radiation detection unit 4 (FPD) to generate magnetism, and the biomagnetism detection unit 2 detects this magnetism. Therefore, by controlling the power supply to the radiation detection unit 4 (FPD) by the control unit, it is possible to minimize the influence of the radiation detection unit 4 (FPD).

Further, the radiation detection unit 4 (FPD) is preferably held by the biomagnetic detection unit 2. Specifically, the radiation detection unit 4 (FPD) is preferably held on the facing surface of the holding unit 2b facing the subject S. By holding the radiation detection unit 4 (FPD) on the opposite surface of the biomagnetic detection unit 2, the radiation detection unit 4 (FPD) can be obtained from the biomagnetic detection unit 2 without providing means for identifying each other's position information (for example, a magnetic marker or the like). The biomagnetic detection result obtained and the morphological image obtained from the radiation detection unit 4 can be accurately superimposed.

The radiation detection unit 4 may be fixed to the biomagnetic detection unit 2 or may be detachably held. Since the radiation detection unit 4 is removable, maintenance of the device becomes easy. If only the detection result of the biomagnetic detection unit 2 is required, the radiation detection unit 4 may be removed.

[Irradiation section]
In the present invention, "radiation" is not limited to generally used X-rays, but includes α-rays, β-rays, γ-rays, etc., which are beams produced by particles (including photons) emitted by radioactive decay. In addition, it is a comprehensive concept that includes beams having energy equal to or higher than these, such as particle beams and cosmic rays. Considering the high versatility, it is preferable to use X-rays as radiation.

As the irradiation unit 5, a conventionally known one can be used as long as it can irradiate a living body with radiation that can be emitted. In the present invention, the radiation irradiation unit 5 may be fixed to the support unit 3 or may be movable with respect to the support unit 3. Since the irradiation unit 5 is fixed to the support unit 3, it is possible to constantly irradiate the subject S on the support unit 3 with radiation from a certain direction. Further, if the radiation irradiation unit 5 is movable with respect to the support unit 3, it is preferable that the radiation detection unit 4 is movable relative to the support unit 3.

[Measurement procedure]
For example, as shown in FIG. 1, in an examination in which X-ray photography and biomagnetic measurement of the chest of a subject (human) are performed at the same time, the support surface 3a of the subject (human) S is a support portion in a horizontal direction. It becomes the prone position (prone position) or the supine position (backward position) of 3 and waits at a predetermined position. The inspector operates the angle adjusting mechanism 6 from an operation unit (not shown) to incline the support portion 3 (support surface 3a) at a predetermined angle. Then, the inspector radiates radiation from the radiation irradiation unit 5 toward the subject S, and obtains an X-ray image which is a detection result from the radiation detection unit 4 (FPD). After that, the power is supplied to the biomagnetic detection unit 2 in a state where the power is not supplied to the radiation detection unit 4 (FPD) by the control unit, and the magnetocardiogram which is the detection result from the biomagnetic detection unit 2 is displayed. obtain.

Alternatively, the inspector supplies power to the biomagnetic detection unit 2 while the power is not supplied to the radiation detection unit 4 (FPD) by the control unit, and the detection result from the biomagnetic detection unit 2 is used. After obtaining a certain magnetocardiogram, radiation may be emitted from the radiation irradiation unit 5 toward the subject S to obtain an X-ray image which is a detection result from the radiation detection unit 4 (FPD). After biomagnetic detection or X-ray imaging, the examiner operates the angle adjustment mechanism 6 to return the support 3 to the horizontal direction so that the subject S can easily descend from the support 3, and then a series of tests are performed. finish.

Hereinafter, the results of measuring the human chest with the above-mentioned biological information measuring device 1 are shown in FIG. Note that FIG. 3 also shows the arrangement M of the magnetic sensor of the biomagnetic detection unit. As can be seen from FIG. 3, it is possible to obtain biological information by superimposing an X-ray image of the chest and a magnetocardiogram by one measurement.

In addition, the aspect of obtaining an X-ray image of the chest of the subject S and a magnetocardiogram can exert a remarkable effect at the time of mass examination. Until now, in electrocardiography, multiple electrodes had to be attached directly to the subject's skin, which could put a mental burden on female examinees and require an examiner to be assigned for electrocardiography. there were. On the other hand, since the magnetocardiographic examination can be performed while wearing a T-shirt or the like, the burden on the female examinee can be greatly reduced. In addition, the radiographic image acquisition and the magnetocardiographic examination can be performed at the same place, which has the effect of saving labor for the inspector.

In the present embodiment, the case where the measurement site is the chest has been described, but it goes without saying that it may be another site or organ such as the brain or spinal cord. Further, in the present embodiment, the support portion 3 provided with the angle adjusting mechanism 6 has been described, but the support portion may not include the angle adjusting mechanism 6 and the support surface may be inclined in advance. Further, in the present embodiment, the case where the support portion 3 is a sleeper has been described, but the support portion 3 may be the backrest of a chair. When the backrest of the chair is provided with the biomagnetic detection unit 2 and the radiation detection unit 4, the backrest may be fixed in an inclined state at an arbitrary angle, and the angle of the backrest may be adjusted to an arbitrary angle. It may be provided with a possible angle adjustment mechanism.
