The appearance information storage unit 3 transfers the appearance information stored therein to the non-projection target detection unit 8 in accordance with an instruction from the control unit 1. In the following description, it is assumed that the appearance information of the medical diagnostic apparatus 20 is stored in the appearance information storage unit 3 in advance. In the present embodiment, the case where the appearance information storage unit 3 stores only the appearance information of the medical diagnostic apparatus 20 will be described. However, naturally, appearance information related to a plurality of medical diagnosis apparatuses may be stored. In this case, the appearance information of the medical diagnostic device 20 used for imaging is selected from the appearance information related to the plurality of medical diagnostic devices and transferred to the non-projection target detection unit 8.

  Upon receiving a notification that the inspected person information has been acquired from the inspected person information acquiring unit 5, the inspection state information generating unit 4 generates inspection state information indicating “before photographing”. Upon receiving a notification indicating the start of imaging from the medical diagnostic apparatus 20, the examination state information generation unit 4 generates inspection state information indicating “under imaging”. Upon receiving a notification indicating the end of imaging from the medical diagnostic apparatus 20, the inspection state information generation unit 4 generates inspection state information indicating “after imaging”. The inspection state information generation unit 4 transfers the inspection state information to the control unit 1 at each generated timing.

  When the subject information is transferred from the medical diagnostic apparatus 20, the subject information acquisition unit 5 notifies the examination state information generation unit 4 that the subject information has been acquired. The subject information acquisition unit 5 transfers the subject information transferred and acquired from the medical diagnostic apparatus 20 to the control unit 1.

  FIG. 2 is a schematic diagram of the medical diagnostic apparatus 20 in the present embodiment.

  The medical diagnostic apparatus 20 is, for example, an MRI apparatus. The medical diagnostic apparatus 20 is not limited to an MRI apparatus, and may be any diagnostic apparatus such as an X-ray CT apparatus, a PET apparatus, or a SPECT apparatus.

  As shown in FIG. 1 or 2, the medical diagnostic apparatus 20 includes a gantry 21, a bed 22, and a console 26. The gantry 21 has MR image photographing means such as a static magnetic field coil, a gradient magnetic field coil, and an RF coil (not shown), and is provided on operation panels 23 a and 23 b for operating the medical diagnostic apparatus 20 and a top plate 25 of the bed 22. An opening 24 for inserting the subject to be inspected into the gantry 21 is provided. The console 26 has display means such as a monitor and input means such as a keyboard. An input screen is displayed on the display means at a predetermined timing. The operator can input to the input screen displayed on the display means via the input means. The information input on the input screen in the present embodiment is the above-described inspected person information having, for example, the inspected person's gender and age category. When the inspected person information is input, the medical diagnostic apparatus 20 transfers the input inspected person information to the inspected person information acquiring unit 5.

  When the imaging of the MR image is started, the medical diagnostic apparatus 20 issues a notification indicating the start of imaging to the examination state information generation unit 4. When the imaging is completed, the medical diagnostic apparatus 20 issues a notification indicating the end of imaging to the examination state information generation unit 4.

  FIG. 3 is a schematic view showing the inside and outside of the examination room 50 in the present embodiment. FIG. 3A corresponds to a plan view of the inside and outside of the examination room 50. FIG. 3B corresponds to a side view of the inside and outside of the examination room 50 viewed from the direction of arrow B in FIG. In FIG. 3B, the operator O and the console 26 in FIG. 3A are omitted. As shown in FIGS. 3A and 3B, the medical diagnostic apparatus 20 in this embodiment has a width W and a height H.

  As described above, the medical diagnostic apparatus 20 in the present embodiment is an MRI apparatus, and since a strong magnetic field is generated in the examination room 50, the video camera 30 and the projector 40 cannot be brought into the examination room 50. . Therefore, the video camera 30 and the projector 40 in this embodiment are installed outside the examination room 50. Note that a magnetically shielded window 51 is provided in the examination room 50, and shooting by the video camera 30 and projection by the projector 40 are performed through the window 51.

  The video camera 30 generates image information by photographing the inside of the examination room 50, and transfers the generated image information to the non-projection target detection unit 8 as necessary as non-projection target detection image information.

  The projector 40 projects the second projection information transferred from the controller 1 into the examination room 50 as projection information projection means. In the present embodiment, the enlargement ratio of the second projection information by the projector 40 and the distance between the wall surface on the window 51 side of the gantry 21 and the projector 40 in FIG. 3A are fixed, and the projection by the projector 40 is In FIG. 3A, the range surrounded by the dotted lines d1 and d2 and in FIG. 3B the dotted lines d3 and d4 is set as the projection path, and this is performed on the wall surface seen from the arrow A side of the gantry 21. That is, the second projection information projected onto the wall surface viewed from the arrow A side of the gantry 21 has a width W and a height H. Hereinafter, a section of the second projection information projected by the projector 40 having a width W and a height H on the wall surface viewed from the arrow A side of the gantry 21 is referred to as a projection plane.

  Next, the operation of the examination room presentation support apparatus 10 in the present embodiment will be described with reference to FIGS.

  FIG. 4 is a flowchart in the present embodiment.

  When the examination is started in step S1, an input screen for inspected person information is displayed on the display means in the console 26 of the medical diagnostic apparatus 20. When the input screen for inspected person information is displayed, the operator inputs the inspected person information via the input means.

  FIG. 5 is an example of an input screen for inspector information displayed on the display means of the console 26 in step S1. The input screen 60 has a gender check field 61 and an age category check field 62. For example, when the subject is a girl, the operator checks “female” in the gender check column 61 and “children” in the age category check column 62, as shown in FIG. When the inspected person information is input, the medical diagnostic apparatus 20 transfers the input inspected person information to the inspected person information acquiring unit 5.

  In step S2, when the subject information is transferred from the medical diagnostic apparatus 20, the subject information acquisition unit 5 notifies the examination state information generation unit 4 that the subject information has been acquired. Upon receiving a notification that the inspector information has been acquired from the inspector information acquisition unit 5, the inspection state information generation unit 4 generates inspection state information indicating “before imaging” and displays the generated “before imaging”. The inspection state information shown is transferred to the control unit 1. Further, the subject information acquisition unit 5 transfers the subject information transferred and acquired from the medical diagnostic apparatus 20 to the control unit 1.

  In step S <b> 3, the control unit 1 transmits the reference image information corresponding to the inspected person information and the comment information corresponding to the inspection state information indicating “before photographing” to the projection information generation unit 7. An instruction is given to the image information / comment information storage unit 2. The reference image information / comment information storage unit 2, in accordance with an instruction from the control unit 1, among the reference image information and comment information stored therein, the reference image information corresponding to the above-described inspected person information and “before photographing” The comment information corresponding to the inspection state information indicating “is transferred to the projection information generation unit 7.

  In step S <b> 4, the control unit 1 instructs the appearance information storage unit 3 to transfer the appearance information to the non-projection target detection unit 8. The appearance information storage unit 3 transfers the appearance information stored therein to the non-projection target detection unit 8 in accordance with an instruction from the control unit 1.

  In step S <b> 5, the projection information generation unit 7 receives the reference image information corresponding to the inspected person information transferred from the reference image information / comment information storage unit 2 and the comment corresponding to the inspection state information indicating “before photographing”. The first projection information is generated by superimposing the information.

  FIG. 6 is a schematic diagram of the first projection information 43 described above. As shown in FIG. 6, the first projection information is obtained by superimposing comment information 41 and reference image information 42, for example. In the present embodiment, as described above, it is assumed that the person to be inspected is a girl. Therefore, it is preferable that the reference image information 42 is easily accessible to the girl. Similarly, in the case where the subject is a boy, an adult male, or an adult female, it is also preferable that the person to be inspected is friendly to each other. Thereby, even if the gender or the age classification is different for each subject to be photographed by the medical diagnostic apparatus 20, the anxiety of each subject can be suitably reduced.

  In step S6, the non-projection target detection unit 8 performs non-projection based on the non-projection target detection image information transferred from the video camera 30 and the appearance information transferred from the appearance information storage unit 3 in step S4. A projection target is detected. First, the non-projection target detection unit 8 collates the non-projection target detection image with the appearance information. The non-projection target detection unit 8 detects the width and height of the gantry 21 in the non-projection target detection image, that is, the above-described projection plane, based on the appearance information. Furthermore, the non-projection target detection unit 8 detects the positions of the operation panels 23a and 23b and the opening 24 in the non-projection target detection image as a non-projection target based on the appearance information. Further, the non-projection target detection unit 8 detects the head of the operator O from the non-projection target detection image, and detects a range in which a predetermined margin is provided around the detected head as a non-projection target. Thereby, the positional relationship between the projection plane and the non-projection target non-projection target detection image is determined. The projection information generation unit 7 associates the first projection information with the projection plane in the non-projection target detection image, and the projection information and the non-projection target detection image on the non-projection target are displayed on the corresponding first projection information. A non-projection target position is set so as to be consistent with the positional relationship.

  FIG. 7 is a schematic diagram of the first projection information 43 and the non-projection target positions 71a, 71b, 71c, 71d set so as to match the positional relationship between the projection plane and the non-projection target in the non-projection target detection image. is there. Here, the non-projection target position 71a corresponds to the operation panel 23a. The non-projection target position 71b corresponds to the operation panel 23b. The non-projection target position 71 c corresponds to the opening 24. The non-projection target position 71d corresponds to a range in which a margin is provided around the head of the operator O.

  In step S7, the projection information generation unit 7 generates second projection information using the non-projection target positions 71a, 71b, 71c, 71d set in the first projection information 43 generated in step S5 as blank portions. In addition, a blank part points out a remarkably dark part compared with other than a blank part, for example, and may have the brightness by projection. Of course, it is not necessary to have brightness by projection.

  FIG. 8 is a schematic diagram of the second projection information 44 having blank portions 81a, 81b, 81c, 81d. Here, the blank portion 81a corresponds to the operation panel 23a. The blank part 81b corresponds to the operation panel 23b. The blank part 81 c corresponds to the opening 24. The blank part 81d corresponds to a range in which a margin is provided around the head of the operator O.

  In step S <b> 8, the control unit 1 transfers the second projection information 44 generated by the projection information generation unit 7 to the projector 40. In the projector 40, the operation panel 23a and the blank part 81a, the operation panel 23b and the blank part 81b, the opening 24 and the blank part 81c, and the margin part around the head of the operator O and the blank part 81d substantially coincide with each other. Thus, the second projection information 44 is projected into the examination room 50.

  FIG. 9 is a schematic diagram of the medical diagnostic apparatus 20 on which the second projection information 44 is projected. In FIG. 9, the operator O is omitted for simplification.

  As shown in FIG. 9, by projecting the second projection information 44, for example, images or comments are not projected on the operation panels 23a and 23b. Therefore, for example, the visibility of numerical information displayed on the operation panels 23a and 23b is not hindered by the projected images or comments, and the operation panels 23a and 23b can be easily operated. Further, as shown in FIG. 9, by projecting the second projection information 44, no image or comment is projected on the opening 24. Therefore, the field of view of the examinee placed on the top board 25 and inserted into the opening 24 is not hindered by the glare of the projected image or comment. Furthermore, as shown in FIG. 9, the second projection information 44 is projected, so that no image or comment is projected on the head of the operator. For this reason, the visual field is not hindered by the glare of the projected image or comment, and the operator can easily operate the operation panels 23a and 23b and set the position of the subject.

  Since the non-projection target detection image information transferred from the video camera 30 is sequentially updated, steps S6 to S8 are performed until the process proceeds to step S9, that is, until imaging by the medical diagnostic apparatus 20 is started. It will be repeated.

  In step S9, when the MR imaging is started by the medical diagnostic apparatus 20, the medical diagnostic apparatus 20 issues a notification indicating the start of imaging to the examination state information generation unit 4. Upon receiving a notification indicating the start of imaging from the medical diagnostic apparatus 20, the inspection state information generation unit 4 generates inspection state information indicating “under imaging”, and displays the generated inspection state information indicating “under imaging” as a control unit. 1 is transferred.

  In step S <b> 10, the control unit 1 instructs the reference image information / comment information storage unit 2 to transfer the comment information corresponding to the examination state information indicating “under imaging” to the projection information generation unit 7. The reference image information / comment information storage unit 2, in accordance with an instruction from the control unit 1, out of the comment information stored by itself, the comment information corresponding to the examination state information indicating “being photographed” is displayed as a projection information generation unit. 7 is transferred.

  In step S11, the projection information generation unit 7 superimposes the reference image information transferred from the reference image information / comment information storage unit 2 in step S3 and the comment information corresponding to the examination state information indicating “under imaging”. Generate projection information. The first projection information generated here is an image that differs from the first projection information generated in step S5 only in comment information.

  In step S12, the non-projection target detection unit 8 determines the non-projection target detection image information transferred from the video camera 30 and the appearance information transferred from the appearance information storage unit 3 in step S4 as needed. A projection target is detected. First, the non-projection target detection unit 8 collates the non-projection target detection image with the appearance information. The non-projection target detection unit 8 detects the width and height of the gantry 21 in the non-projection target detection image, that is, the above-described projection plane, based on the appearance information. Furthermore, the non-projection target detection unit 8 detects the positions of the operation panels 23a and 23b and the opening 24 in the non-projection target detection image as a non-projection target based on the appearance information. Further, the non-projection target detection unit 8 detects the head of the operator O from the non-projection target detection image, and detects a range in which a predetermined margin is provided around the detected head as a non-projection target. Thereby, the positional relationship between the projection plane and the non-projection target non-projection target detection image is determined. The projection information generation unit 7 associates the first projection information with the projection plane in the non-projection target detection image, and the projection information and the non-projection target detection image on the non-projection target are displayed on the corresponding first projection information. A non-projection target position is set so as to be consistent with the positional relationship.

  In step S13, the projection information generation unit 7 generates second projection information in which the non-projection target position set in the first projection information generated in step S11 is a blank part.

  In step S <b> 14, the control unit 1 transfers the second projection information generated by the projection information generation unit 7 to the projector 40. The projector 40 projects the second projection information into the examination room 50 so that the non-projection target and the blank portion substantially coincide with each other. The second projection information projected here has different comment information from the second projection information projected in step S8.

  Since the non-projection target detection image information transferred from the video camera 30 is sequentially updated, steps S12 to S14 are performed until the process proceeds to step S15, that is, until imaging by the medical diagnostic apparatus 20 is completed. It will be repeated.

  When the imaging of the MR image is completed by the medical diagnostic apparatus 20 in step S15, the medical diagnostic apparatus 20 issues a notification indicating the end of imaging to the examination state information generation unit 4. Upon receiving a notification indicating the end of imaging from the medical diagnostic apparatus 20, the inspection state information generation unit 4 generates inspection state information indicating “after imaging”, and transmits the generated inspection state information indicating “after imaging” to the control unit. 1 is transferred.

  In step S <b> 16, the control unit 1 instructs the reference image information / comment information storage unit 2 to transfer the comment information corresponding to the examination state information indicating “after imaging” to the projection information generation unit 7. The reference image information / comment information storage unit 2, in accordance with an instruction from the control unit 1, among the comment information stored by itself, comment information corresponding to the examination state information indicating “after photographing” is displayed as a projection information generation unit. 7 is transferred.

  In step S <b> 17, the projection information generation unit 7 superimposes the reference image information transferred from the reference image information / comment information storage unit 2 in step S <b> 3 and the comment information corresponding to the examination state information indicating “after photographing”. Generate projection information. The first projection information generated here is an image that differs from the first projection information generated in step S5 and step S11 only in comment information.

  In step S18, the non-projection target detection unit 8 performs non-projection based on the non-projection target detection image information transferred from the video camera 30 and the appearance information transferred from the appearance information storage unit 3 in step S4. A projection target is detected. First, the non-projection target detection unit 8 collates the non-projection target detection image with the appearance information. The non-projection target detection unit 8 detects the width and height of the gantry 21 in the non-projection target detection image, that is, the above-described projection plane, based on the appearance information. Furthermore, the non-projection target detection unit 8 detects the positions of the operation panels 23a and 23b and the opening 24 in the non-projection target detection image as a non-projection target based on the appearance information. Further, the non-projection target detection unit 8 detects the head of the operator O from the non-projection target detection image, and detects a range in which a predetermined margin is provided around the detected head as a non-projection target. Thereby, the positional relationship between the projection plane and the non-projection target non-projection target detection image is determined. The projection information generation unit 7 associates the first projection information with the projection plane in the non-projection target detection image, and the projection information and the non-projection target detection image on the non-projection target are displayed on the corresponding first projection information. A non-projection target position is set so as to be consistent with the positional relationship.

  In step S19, the projection information generation unit 7 generates second projection information 44 with the non-projection target position set in the first projection information generated in step S17 as a blank portion.

  In step S <b> 20, the control unit 1 transfers the second projection information generated by the projection information generation unit 7 to the projector 40. The projector 40 projects the second projection information into the examination room 50 so that the non-projection target and the blank portion substantially coincide with each other. The second projection information projected here is different in comment information from the second projection information projected in steps S8 and S14.

  Since the non-projection target detection image information transferred from the video camera 30 is sequentially updated, steps S18 to S20 are repeated until the inspection is completed.

  In step S21, the inspection ends.

  As described above, the in-laboratory presentation support apparatus 10 according to the present embodiment projects an image that makes the inspected person feel secure and comments in accordance with the inspection situation in the inspection room, thereby making the inspected person feel uneasy. A smooth inspection can be carried out by not projecting to an unpreferable location where the projection of the image or comment is reduced.

  In the present embodiment, the case has been described where the wall surface of the gantry 21 on the arrow A side in FIG. 3A is relatively flat and the second projection information is projected onto this wall surface. For example, the wall surface onto which the second projection information is projected. May have a complicated shape. In this case, it is preferable to use a projection technique that takes into account the complicated shape of the wall surface, so-called projection mapping technique.

  In this embodiment, the case where a range provided with a predetermined margin around the operator's head is detected as a non-projection target has been described. For example, a range provided with a predetermined margin around the operator's hand is not projected. It may be detected as a target. This prevents the operator from being disturbed by the projected image or comment when performing some work. Note that which part is detected as a non-projection target may be changed as necessary.

  In the present embodiment, the case where the operation panels 23a and 23b and the opening 24 are detected as non-projection targets has been described. However, other parts may be detected as non-projection targets. For example, when the top plate 25 is detected as a non-projection target, the subject is not obstructed by the projected image or comment even if the subject is not positioned in the opening 24.

  In the present embodiment, the case where the comment information automatically changes according to the progress of the examination has been described. However, the comment information may be changed by an operation by an operator. In this case, for example, as a predetermined input screen, three kinds of switching buttons “before photographing”, “under photographing”, and “after photographing” are displayed on the display means of the console 26, and the switching buttons are displayed via the operation means of the console 26. Comment information is switched by selecting any of the above. This makes it possible to switch the comment information at a timing that is more appropriate to the situation.

  In the present embodiment, the case where the age category is selected by checking the age category check field 62 in the input of the subject information has been described, but the age of the subject may be entered as a numerical value. In this case, for example, 0 to 12 years old is “child”, 13 years old and older is “adult”, and a numerical value and an age classification are associated in advance, and an age classification corresponding to the age input as a numerical value is automatically set. Selected.

  In the present embodiment, the case where the inspected person information is sex and age classification has been described. For example, the inspected person information includes the name of the inspected person, and the reference image information / comment memory is based on the inspected person name. The comment information transferred from the unit 2 may be supplemented. In this case, for example, the comment information such as "Hello ○○-san" by an instruction from the control unit 1 is transferred from the reference image information / comment storage unit 2, the inspection's name is incorporated into the ○○ part of the comment information. As a result, the second projection information including the inspected person's name is projected into the examination room 50, so that the inspected person has a sense of familiarity with the medical diagnostic apparatus 20 and takes a sense of security. You will be able to face.

  In the present embodiment, the case where the information related to the inspected person is sex and age classification has been described, but the inspection person's inspection history, nationality, inspection site, inspection time, etc. are included and based on the information. Thus, reference image information and comment information may be selected, and the first projection information may be generated. Alternatively, the information on the subject is any one of gender, age category, history of examination, nationality, examination site, examination time, etc., and reference image information and comment information are selected based on the information. One projection information may be generated. For example, if the information on the subject is the examination time and the examination time is in the morning, the reference image information and comment information that are the basis of the first projection information are reminiscent of the morning. On the other hand, if the inspection time is the evening time zone, the reference image information and the comment information that are the basis of the first projection information are reminiscent of the evening.

  In the present embodiment, the case where the reference image information and the comment information are stored in the reference image information / comment storage unit 2 has been described. However, the reference image information is provided outside the examination room presentation support apparatus 10 for each examination, for example. May be obtained from the obtained image server. Alternatively, the comment information may be input every time, for example, by an operator via the operation means of the console 26. This makes it possible to project more appropriately.

  In the present embodiment, the case where the inspector information is input using the operation unit of the console 26 has been described. However, for example, the inspector information is acquired from Radiology Information System (RIS) or Hospital Information System (HIS). May be. As a result, it is possible to save the operator from inputting the inspected person information.

  In the present embodiment, the case where the second projection information to be projected is a still image has been described, but it may be a moving image.

  In the present embodiment, a case has been described in which the non-projection target position set in the first projection information is set as a blank part, and other than the blank part of the second projection information is left as it is. For example, the second projection is avoided so as to avoid the blank part. Information may be changed.

  FIG. 10 is a schematic diagram of the second projection information when the second projection information is changed so as to avoid the blank portion. FIG. 10A shows a case where the entire projection of the operator is a non-projection target, and the second projection information is changed so that the comment information 41a is divided so as to avoid the blank portion 81e. It is possible to prevent the comment information 41a from being blocked by the portion 81e. FIG. 10B shows a case where the second projection information is changed so that the comment information 41a is always located above the blank portion 81e, and the comment information 41a is blocked by the blank portion 81e. Can be prevented. FIG. 10C shows a case where, for example, the second projection information is a moving image, and the reference image information is changed so that the reference image information 42a indicating the ball is reflected on the blank portion 81e. 2 Projection information can be made more playful.

  In the present embodiment, as shown in FIG. 3A, the case where the projector 40 is positioned in front of the gantry 21 has been described, but the projector 40 may not be positioned in front of the gantry 21.

  FIG. 11 is a schematic diagram showing the inside and outside of the examination room 50 when the projector 40 is disposed obliquely with respect to the front of the gantry 21 and the second projection information is projected for the convenience of the layout of the examination room 50. Projection by the projector 40 is performed on the wall surface on the arrow C side of the gantry 21 using the range surrounded by the dotted lines d5 and d6 as a projection path. In this case, since the position of the point p on the operation panel 23a side is usually closer to the projector 40 than the position of the point q on the operation panel 23b side, the second projection information projected at the position of the point q is the point p. The second projection information projected onto the position is enlarged and projected. That is, the second projection information is projected with distortion. However, for example, the projection information generation unit 7 reduces the projected second projection information projected at the position q in advance, so that the second projection information projected at the position of the point p and the position of the point q are the same. The distortion of the projected second projection information can be corrected by making the size. In addition, in order to correct the distortion of the second projection information based on the projection direction, for example, the examination room presentation support apparatus 10 may include a distortion correction unit (not shown). The above may be performed by the projector 40.

  In addition, since the distance between the position of the point p and the position of the point q from the projector 40 is different, normally, for example, when the second projection information is projected while focusing on the position of the point p, the position is projected to the position of the point q. The second projection information is out of focus and blurred. However, for example, the projection information generation unit 7 corrects the second projection information projected at the position of the point q so that it is in focus at the point q, so that the focal point is at both the position of the point p and the position of the point q. The matched second projection information can be projected.

  In the present embodiment, the enlargement ratio of the second projection information by the projector 40 and the case where the distance between the wall surface of the gantry 21 and the projector 40 is fixed have been described. However, the enlargement ratio of the second projection information by the projector 40 and the gantry The distance between the wall surface 21 and the projector 40 may not be fixed. In this case, for example, a projector position detection unit (not shown) that detects the position of the projector with respect to the wall surface of the gantry 21 that projects the second projection information, and an enlargement ratio of the second projection information corresponding to the detected position of the projector are determined. It is preferable to have an enlargement factor determination unit (not shown).

  In the present embodiment, the case has been described where the comment information changes in accordance with the progress of the examination. For example, the reference image information may change.

  In the present embodiment, the case where the second projection information is projected at any timing before, during, and after the image capture has been described. However, for example, the image may not be projected when the emergency subject is imaged. Alternatively, for example, projection and non-projection may be switched via the operation means of the console 26.

  In the present embodiment, the case where the image information generated by the video camera 30 is used as non-projection target detection image information has been described. However, for example, the video camera 30 may be replaced by an infrared camera, a motion sensor, a thermography, or the like.

  In the present embodiment, the case where there is one projector has been described, but the second projection information may be projected using a plurality of projectors.

  FIG. 12 is a schematic diagram of the second projection information 44a and 44b when two projectors are used. As shown in FIG. 12, when the overlapping portion 45 is generated by the second projection information 44a and 44b, the brightness of the overlapping portion 45 and the portion other than the overlapping portion 45 of the second projection information 44a and 44b is constant. It is preferable to adjust the brightness of the portion corresponding to the overlapping portion 45 of the second projection information 44a and 44b.

  When projection is performed using a plurality of projectors, for example, a shaded portion of one projector may be interpolated by another projector. Alternatively, the projector to be used may be changed depending on the standing position of the examinee or engineer.

  In the present embodiment, the case where the appearance information storage unit 3 stores three-dimensional image information indicating the shape of the medical diagnostic apparatus 20 as appearance information has been described, but the appearance information stored in the appearance information storage unit 3 is For example, it may be two-dimensional image information indicating the shape of the medical diagnostic apparatus 20 viewed from a plurality of directions.

  In the present embodiment, the case where the appearance information storage unit 3 stores information indicating the shape of the medical diagnostic apparatus 20 has been described. However, the color of the medical diagnostic apparatus 20 may be stored. In this case, for example, the projection information generation unit 7 changes the color of the second projection information to be projected in accordance with the color of the medical diagnostic apparatus 20. This makes it possible to project the second projection information with a color that does not feel strange.

  In this embodiment, the examination room presentation support apparatus 10 includes a control unit 1, reference image information / comment information storage unit 2, appearance information storage unit 3, examination state information generation unit 4, and inspected person information acquisition unit 5. However, the examination room presentation support apparatus 10 may include the video camera 30 and the projector 40. Conversely, for example, the examination room presentation support device 10 does not have to include the reference image information / comment information storage unit 2, the appearance information storage unit 3, the examination state information generation unit 4, and the inspected person information acquisition unit 5.

  In the present embodiment, the case where the second projection information is projected onto the medical diagnostic apparatus 20 has been described. However, the second projection information may be projected onto the ceiling or wall surface of the examination room 50.

  In the present embodiment, the case where the reference image information and the comment information stored in the reference image information / comment information storage unit 2 are transferred to the projection information generation unit 7 and the projection information generation unit 7 generates the first projection information has been described. However, the first projection information including reference image information and comment information may be stored in a first projection information storage unit (not shown). In this case, the second projection information is generated based on the first projection information stored in the first projection information storage unit.
