Medical image capturing apparatus and control method of the same
There is provided a medical image capturing apparatus including a table on which a subject is placed, a scan gantry unit that includes a detection unit which detects a signal obtained from the subject, an image generation unit that generates a medical image by using a detection signal transmitted from the detection unit, a display unit that displays the medical image, a camera that images the subject on the table, and a processor. The processor designates an imaging position with respect to the subject before movement of the table, acquires a camera image captured by the camera before, during, or after the movement of the table, and generates a superimposed image in which the imaging position is superimposed on the camera image and displays the superimposed image on the display unit.
1 . A medical image capturing apparatus comprising:
a table on which a subject is placed;
a scan gantry unit that includes a detection unit which detects X-rays transmitted through the subject;
an image generation unit that generates a medical image by using a detection signal transmitted from the detection unit;
a display unit that displays the medical image;
a camera that images the subject on the table; and
a processor, configured to:
designate an imaging position with respect to the subject before movement of the table;
acquire a camera image captured by the camera during the movement of the table; and
generate a superimposed image in which the designated imaging position is superimposed on the subject in the camera image and displays the superimposed image on the display unit,
wherein the processor acquires the camera image during the movement of the table as a video and displays electrocardiogram data of the subject on the display unit in synchronization with the superimposed image generated based on the video.
2 . The medical image capturing apparatus according to claim 1 ,
wherein the processor designates the imaging position based on a pre-movement image, which is a camera image captured by the camera before the movement of the table, and
the processor generates the superimposed image by calculating coordinates of the imaging position in a post-movement image, which is the camera image during the movement of the table or a camera image captured by the camera after the movement of the table, based on a difference between the post-movement image and the pre-movement image.
3 . The medical image capturing apparatus according to claim 2 ,
wherein the processor further superimposes an outer shape of the subject on the superimposed image.
4 . The medical image capturing apparatus according to claim 2 ,
wherein the processor further superimposes an imaging field of view of the scan gantry unit on the superimposed image.
5 . A control method of a medical image capturing apparatus including a table on which a subject is placed, a scan gantry unit that includes a detection unit which detects X-rays transmitted through the subject, an image generation unit that generates a medical image by using a detection signal transmitted from the detection unit, a display unit that displays the medical image, and a camera that images the subject on the table, the control method comprising:
acquiring a camera image captured by the camera during the movement of the table; and
generating a superimposed image in which an imaging position is superimposed on the camera image and displaying the superimposed image on the display unit, wherein the imaging position is designated with respect to the subject before movement of the table,
wherein the camera image during the movement of the table is acquired as a video, and electrocardiogram data of the subject is displayed on the display unit in synchronization with the superimposed image generated based on the video.
