An imaging system, comprising: a gantry defining a central imaging bore and an imaging axis extending through the bore, the gantry comprising at least one imaging component for obtaining images of an object located within the bore, and the at least one imaging component comprises an x-ray source and an x-ray detector; at least one support member (31; 33) that supports the gantry, and the gantry is displaceable with respect to the at least one support member in a vertical direction, and the gantry is rotatable with respect to the at least one support member between a first position in which the at least one support member supports the gantry with the imaging axis in a vertical orientation, and a second position in which the at least one support member supports the gantry with the imaging axis in a horizontal orientation, and the gantry and at least one support member are displaceable in a horizontal direction relative to an object positioned within the bore; a base having one or more rails the at least one support member extending in the vertical direction from a top surface of the base and being displaceable in the horizontal direction along the one or more rails, a first drive mechanism for displacing the gantry relative to the at least one support member in the vertical direction; and a second drive mechanism for displacing the gantry and the at least one support member along the one or more rails in the horizontal direction for obtaining a horizontal X-ray computed tomography scan of the object, wherein the system is configured to obtain a vertical x-ray computed tomography scan of a human patient in a weight bearing standing position. a gantry defining a central imaging bore and an imaging axis extending through the bore, the gantry comprising at least one imaging component for obtaining images of an object located within the bore, and the at least one imaging component comprises an x-ray source and an x-ray detector; at least one support member (31; 33) that supports the gantry, and the gantry is displaceable with respect to the at least one support member in a vertical direction, and the gantry is rotatable with respect to the at least one support member between a first position in which the at least one support member supports the gantry with the imaging axis in a vertical orientation, and a second position in which the at least one support member supports the gantry with the imaging axis in a horizontal orientation, and the gantry and at least one support member are displaceable in a horizontal direction relative to an object positioned within the bore; a base having one or more rails the at least one support member extending in the vertical direction from a top surface of the base and being displaceable in the horizontal direction along the one or more rails, a first drive mechanism for displacing the gantry relative to the at least one support member in the vertical direction; and a second drive mechanism for displacing the gantry and the at least one support member along the one or more rails in the horizontal direction for obtaining a horizontal X-ray computed tomography scan of the object, wherein the system is configured to obtain a vertical x-ray computed tomography scan of a human patient in a weight bearing standing position.
