An imaging apparatus (103) for diagnosis includes a display unit (113) for displaying a plurality of generated cross-sectional images sequentially in chronological order, first and second operation members (341,342) which are arranged on an operation panel (112) and which are for appending a bookmark to the cross-sectional image, and a control unit (111) for appending a bookmark to a cross-sectional image during display in response to a user operation toward at least one of the first and second operation members during the display of the cross-sectional image by the display unit, wherein the first operation member (341) is provided on the right side seen from the center portion in the right and left direction with respect to a user in a case in which the user directly-faces the operation panel, and the second operation member (342) is provided on the left side seen from the center portion of the operation panel. Therefore, regardless of whether the users dominant hand is his/her right hand or left hand, it is possible to provide a good operability of the bookmark buttond (341, 342).
