The side view in the bed side of the mount frame shown in FIG. The expanded sectional view which shows the detailed structural example of the 1st illumination part shown in FIG. 1, and an exterior cover.

  An image diagnostic apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a configuration diagram of a magnetic resonance imaging apparatus as an example of an image diagnostic apparatus according to an embodiment of the present invention, and FIG. 2 is a side view of the gantry shown in FIG. FIG. 2A shows a state before the bed is installed, and FIG. 2B shows a state after the bed is installed.

  The magnetic resonance imaging apparatus 1 includes a gantry 2, a bed 3, and a control system 4. The gantry 2 incorporates an imaging unit 8 for imaging the subject O, such as a static magnetic field magnet 5, a gradient magnetic field coil 6, and a whole body coil 7. An imaging space S of the subject O is formed in the bore of the gantry 2. The bed 3 is connected to the opening B on the side surface on one side of the gantry 2. The subject O can be set in the imaging space S by feeding the top 3 </ b> A of the bed 3 into the gantry 2. The subject call 9 can be given a patient call 9 for notifying an emergency situation.

  The gantry 2 is provided with a first illumination unit 11 and a second illumination unit 12. The first illumination unit 11 is an illumination unit that irradiates light L toward the outside of the gantry 2. The second illuminating unit 12 is an illuminating unit that irradiates the light L toward the imaging space inside the gantry 2. For this reason, the 2nd illumination part 12 can be provided in the opening part vicinity of the mount frame 2 or in a bore | bore. On the other hand, the first illumination unit 11 can be provided on the side surface of the gantry 2 on the bed 3 side. That is, the first illumination unit 11 can be provided on the bed 3 side of the exterior cover 13 of the gantry 2.

  In this case, if the first illumination unit 11 is configured to generate light L having a shape corresponding to a portion excluding the portion to which the bed 3 is connected, on the bed 3 side, the first lighting unit 11 considering the attachment / detachment of the bed 3 is considered. The maintainability of the illumination unit 11 can be improved. As a specific example, arc-shaped light L excluding a portion to which the bed 3 is connected can be generated on the bed 3 side. Or you may make it generate the light L to the bed 3 side from the several area | region intermittently provided along the circular arc except the part to which the bed 3 is connected. Therefore, when the first illuminating unit 11 sees the gantry 2 from the bed 3 side, the first illumination unit 11 generates light L in a portion outside the bore of the gantry 2 into which the subject O is inserted and excluding a portion where the bed 3 is connected. Will be allowed to.

  In the illustrated example, the C-shaped light L is generated toward the outside of the gantry 2. For this reason, it is possible to improve the visibility of illumination light to a person other than the subject O, such as an operator or a visitor.

  FIG. 3 is an enlarged cross-sectional view illustrating a detailed structure example of the first illumination unit 11 and the outer cover 13 illustrated in FIG. 1.

  3 is an enlarged cross-sectional view of the AA cross section shown in FIG. As shown in FIG. 3, the gantry 2 includes a static magnetic field magnet 5, a gradient magnetic field coil 6, and a whole body coil 7. That is, the static magnetic field magnet 5, the gradient magnetic field coil 6, and the whole body coil 7 are protected by the exterior cover 13 of the gantry 2.

  The 1st illumination part 11 can be provided in the mount frame 2 so that the light L can be irradiated from the mount frame 2 to the bed 3 side. In this case, it is preferable that the first illumination unit 11 performs indirect illumination toward the bed 3 side. That is, it is preferable that the light L irradiated to the bed 3 side is reflected light reflected on the reflection region 13 a of the exterior cover 13.

  For example, as shown in FIG. 3, the reflection region 13 a of the exterior cover 13 in which the shape of the exterior cover 13 is curved or inclined can be used as a reflector of light emitted from the first illumination unit 11. In the example shown in FIG. 3, the light irradiated in the vertical direction from the first illumination unit 11 is reflected on the reflection region 13 a of the exterior cover 13 on the bed 3 side of the gantry 2, and is reflected in the horizontal direction or the oblique direction. The shape of the first illumination unit 11 and the exterior cover 13 is designed so that the light is generated on the bed 3 side. In addition, you may irradiate light to the reflection area 13a of the exterior cover 13 from the illumination part 11 in the diagonal direction.

  More specifically, a ring-shaped fixing member 15 for fixing the light source 14 of the first illumination unit 11 is fixed to an end of the gantry 2, for example, a side surface of the static magnetic field magnet 5 on the bed 3 side. A light source 14 having a light emission direction in the diameter direction is arranged in a ring shape along the ring-shaped fixing member 15. In other words, the light sources 14 are arranged radially. Light is emitted upward from the light source 14. Therefore, the light source 14 is protected by the transparent cover 16. And the light irradiated upwards from the light source 14 permeate | transmits the transparent cover 16, is reflected by the exterior cover 13, and the bed 3 side is illuminated by reflected light.

  As the light source 14, a light emitting diode (LED) is used so as not to be affected by a magnetic field. Desirably, a large number of three-color LEDs are circularly arranged along the fixing member 15 as the light source 14. However, a single color LED such as a white LED may be used.

  Moreover, as a material of the exterior cover 13, the plastic conventionally used for the exterior cover 13 of the mount frame 2 can be used. However, in order to obtain a light reflection effect more effectively, the shape can be reduced, and the color or material can have a high reflection efficiency.

  By generating the reflected light in this way, direct light can be prevented from entering the human eye. Thereby, visual stimulation can be reduced.

  On the other hand, the control system 4 is a system that controls the bed 3 and the imaging unit 8 and generates MR image data based on the MR signals collected in the imaging unit 8. For this purpose, the control system 4 is connected to each component of the imaging unit 8 by a signal cable 17.

Accordingly, when the magnetic resonance imaging apparatus 1 is in the system ready state, the light is blue, when the warning is generated, the light is red, and when the patient call 9 is pressed, the light intensity is large and the light blinks red. When is in the power saving mode, it is possible to control the illumination by determining a desired illumination condition in advance, such as lighting with a small amount of light and green. That is, it is possible to set the illumination conditions of the first illumination unit 11 and the second illumination unit 12 according to information regarding at least one of the magnetic resonance imaging apparatus 1 and the subject O.

  In addition to the above-described example, when the illumination control unit 19 displays at least one of the elapsed time from the start of imaging and the remaining time of imaging as a change in the light L emitted from the first illumination unit 11, Lighting control such as changing the lighting range clockwise, for example, is also possible.

  Therefore, the illumination control unit 19 is connected to a device such as the patient call 9 as necessary. And it is comprised so that the information used as a trigger of the illumination control of the 1st illumination part 11 and the 2nd illumination part 12 can be acquired from the apparatus made into object. In addition, the illumination control unit 19 is configured to acquire the device information such as the remaining time of imaging from the device control unit 18.

  In addition, you may make it the illumination control part 19 control the 1st illumination part 11 and the 2nd illumination part 12 in order to give a patient a sense of security. For example, when the patient is set on the top 3 </ b> A on his / her back on the foot first, the patient is relieved by the illumination by the first illumination unit 11 until the top 3 </ b> A is completely sent into the bore. be able to. Subsequently, after the patient is sent into the gantry 2 by the horizontal movement of the top 3 </ b> A, the patient can feel a sense of security by the illumination by the second illumination unit 12. In this case, by changing the lighting range of the second illumination unit 12, it is possible to notify the patient of the remaining time of imaging or the elapsed time from the start of imaging.

  That is, the magnetic resonance imaging apparatus 1 as described above is provided on the side surface of the gantry 2 with the first illumination unit 11 that generates light having a shape corresponding to the portion excluding the portion to which the bed 3 is connected on the bed 3 side.
