It will be viewed through plate 5. Furthermore, although the position of the patient M within the gantry 1 changes depending on the imaging location, the position where the patient M views the information on the display 3 from the reflector 5 does not change and is always constant, making it difficult to see the information on the display 3. That's not the case. In addition, in the method (2), if the reflecting plate 5 is formed into a continuous chevron shape, the light of the information displayed on the display 3 is reflected once on the slope 5a of the reflecting plate 5, and then further reflected on the opposing slope 5a.
The light reflected at point b enters patient M's eyes. This allows the patient to see the information displayed on the display 3 in a normal manner. Furthermore, in the method (2), when the screw 7 at one end of the shaft is loosened, the display 3 installed at the end of the top plate 2 rotates along the groove 8 about a point 6 at the other end, and Top plate 2
Information light from the display 3 is once reflected by the reflecting plate 9 on the opposite side of the gantry and then reflected by the reflecting plate 5 on the ceiling of the gantry. Therefore, patient M
When viewing the information, since the information on the display 3 is reflected twice, the patient M sees it in a normal manner and can accurately see it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a magnetic resonance image according to the present invention.
FIG. 2 is an overall perspective view of an in-gantry display device for a scanning device. A display 3 is provided at the tip of the top plate 2 on which the patient M is placed, that is, above the patient's M head. In this case, the display 3 may be the top plate 2 or the bed 4 near the top plate. In short, the display 3 is the moving top plate 2 or the bed 4.
It is placed on the upper part of the head of patient M. Reference numeral 5 denotes a reflecting plate, which is installed on the ceiling of the hole 1a of the gantry 1 in the form of a rectangle as large as possible. Note that metal members cannot be used inside the gantry 1. Therefore, as the reflecting plate 5, a resin plate such as an acrylic plate is used, which is designed to reflect as much as possible.

FIG. 2 is an internal sectional view of the magnetic resonance imaging apparatus according to the present invention. As shown in this figure, a patient M placed in a gantry 1 uses a reflector 5 installed on the ceiling to transmit information displayed on a display 3 installed at the upper end of the head of a bed or a top plate 2. You will see it through. Note that it is preferable to use a luminous material that shines as brightly as possible for the characters and the like displayed on the display 3. For example, if a light emitting diode (LED), a luminous fiber, or the like is used as the light emitter, it will be easily recognized.

FIG. 3 is a sectional view showing a position where the head is imaged and a position where the abdomen is imaged. In this case, the image is usually captured at position A at the center of the gantry 1. Therefore, the position of the patient M within the gantry 1 varies depending on the imaging location, but the position of the patient M
The position from which the information on the display 3 is viewed from the reflection plate 5 does not change and is always constant, so that the information on the display 3 is not difficult to see.

FIG. 4 shows a modified embodiment of the in-gantry display unit of the magnetic resonance imaging apparatus according to the present invention. That is, in the embodiments shown in FIGS. 1 to 3 described above, the information on the display 3 is viewed as being reflected by the reflector plate 5, so that the information appears in reverse. Therefore, as shown in FIG. 4, the reflector 5 is formed into a predetermined continuous mountain shape so that the information light displayed on the display 3 is reflected once on the slope 5a of the reflector 5, and then the light reflected on the opposite slope 5b is transmitted to the patient. Make it visible to M. This allows the patient to see the information displayed on the display 3 in a normal manner.

FIGS. 5 to 7 show still other modified embodiments of the present invention. That is, as shown in FIG. 5, in this modified embodiment, when the indicator 3 installed at the end of the top plate 2 loosens the screw 7 at one end of the shaft, a groove 8 is formed around a point 6 at the other end.
It is configured to be rotatable along the Then, as shown in FIG. 6, when the screw 7 is loosened and the display 3 is rotated, a reflector 9 is provided on one side of the top plate 2, and the information light from the display 3 is once reflected by the reflector 9. After being reflected, the light is reflected by a reflecting plate 5 shown in FIGS. 1 and 2. Therefore, as shown in FIG. 7, when the patient M views the information on the display 3, the light that conveys the information displayed on the display 3 is reflected by the reflector 9, and the light transmitted from the reflector 9 installed on the ceiling of the gantry 1. At step 5, the light is further reflected and enters the patient M's eyes. Furthermore, with such a configuration, since the information on the display 3 is reflected twice, the patient M sees it in a normal manner and can accurately view it.

[0013]

Effects of the Invention Since the in-gantry display device for a magnetic resonance imaging apparatus according to the present invention has the configuration described in detail above, the information on the display device can be visually recognized by the patient even when the patient moves within the gantry. The position does not change, and you can always see it from the same position. Further, since a reflector is used, the focal point may be set at about 50 cm to 100 cm, and even people with poor eyesight can easily confirm the contents of the display. Normally, patients are asked to take off their glasses when taking images, but since there is no need to provide an external display, it is convenient even for people with nearsightedness to see the contents of the display without any difficulty. Furthermore, if the light is reflected twice, the information reflected on the reflector will have a normal shape, making it easier to see.
