The gantry acquires data. The bed supports a table top such that the table top is horizontally and vertically movable relative to a floor surface. The processing circuitry determines a lift route of the table top from an initial height to a target height to be either a first route or a second route. The first route is in which the table top is vertically lifted relative to the floor surface from the initial height to the target height. The second route is in which the table top is vertically lifted, while being horizontally moved, relative to the floor surface from the initial height to the target height. ## Claims ### Claim 1 A medical imaging diagnosis apparatus comprising: a gantry configured to acquire data; a bed configured to support a table top such that the table top is horizontally and vertically movable relative to a floor surface; and processing circuitry configured to select, as a lift route of the table top from an initial height to a target height, either a first route or a second route, the first route being in which the table top is vertically lifted relative to the floor surface from the initial height to the target height, the second route being in which the table top is vertically lifted, while being horizontally moved, relative to the floor surface from the initial height to the target height, wherein the first route is selected when a scan is a head scan, an external light projector is used, a direction of a subject is head-first, or a stretcher is used. ### Claim 2 (depends on 1) The medical imaging diagnosis apparatus of claim 1, wherein the processing circuitry is configured to select the lift route to be one of the first route and the second route, in accordance with a scan condition or patient information relating to the subject. ### Claim 3 (depends on 2) The medical imaging diagnosis apparatus of claim 2, wherein the scan condition is at least one of, a condition as to whether or not the scan is head scan, a condition relating to presence/absence of use of the external light projector, a condition relating to the direction of the subject on the table top, and a condition relating to presence/absence of use of the stretcher. ### Claim 4 (depends on 2) The medical imaging diagnosis apparatus of claim 2, wherein when a scan condition of a previous examination is included in the patient information relating to the subject of an examination target, the processing circuitry is configured to select the lift route of a present examination, based on the scan condition of the previous examination. ### Claim 5 (depends on 2) The medical imaging diagnosis apparatus of claim 2, wherein when a lift route of a previous examination is included in the patient information relating to the subject of an examination target, the processing circuitry is configured to select the lift route of the previous examination to be the lift route of a present examination. ### Claim 6 (depends on 2) The medical imaging diagnosis apparatus of claim 2, further comprising an interface for selecting one of the first route and the second route, wherein the processing circuitry is configured to select the first route as the lift route when the first route is selected via the interface after the lift route was selected in accordance with the scan condition or the patient information, and the processing circuitry is configured to select the second route as the lift route when the second route is selected via the interface after the lift route was selected in accordance with the scan condition or the patient information. ### Claim 7 (depends on 1) The medical imaging diagnosis apparatus of claim 1, further comprising an interface for selecting one of the first route and the second route, wherein the processing circuitry is configured to select the first route as the lift route when the first route is selected via the interface, and the processing circuitry is configured to select the second route as the lift route when the second route is selected via the interface. ### Claim 8 (depends on 1) The medical imaging diagnosis apparatus of claim 1, further comprising a display configured to display the selected lift route. ### Claim 9 (depends on 1) The medical imaging diagnosis apparatus of claim 1, wherein the bed includes a support frame configured to support the table top such that the table top is slidable in a long-axis direction of the table top, and a base configured to support the support frame such that the support frame is slidable in the long-axis direction and such that the support frame is vertically movable relative to the floor surface, the base is configured to be capable of structurally moving the support frame in the long-axis direction in interlock with a vertical movement of the support frame. ### Claim 10 (depends on 1) The medical imaging diagnosis apparatus of claim 1, wherein the gantry includes an imaging mechanism for X-ray CT scan, MR scan, SPECT scan or PET scan. ### Claim 11 A scan planning apparatus connected to a medical imaging diagnosis apparatus including a gantry configured to acquire data, and a bed configured to support a table top such that the table top is horizontally and vertically movable relative to a floor surface, the scan planning apparatus comprising: processing circuitry configured to select, as a lift route of the table top from an initial height to a target height, either a first route or a second route, the first route being in which the table top is vertically lifted relative to the floor surface from the initial height to the target height, the second route being in which the table top is vertically lifted, while being horizontally moved, relative to the floor surface from the initial height to the target height, wherein the first route is selected when a scan is a head scan, an external light projector is used, a direction of a subject is head-first, or a stretcher is used; and an interface configured to notify the medical imaging diagnosis apparatus of the selected lift route. ### Claim 12 (depends on 11) The scan planning apparatus of claim 11, wherein the processing circuitry is configured to select the lift route to be one of the first route and the second route, in accordance with a scan condition or patient information relating to the subject. ### Claim 13 (depends on 12) The scan planning apparatus of claim 12, wherein the scan condition is at least one of a condition as to whether or not the scan is head scan, a condition relating to presence/absence of use of the external light projector, a condition relating to the direction of the subject on the table top, and a condition relating to presence/absence of use of the stretcher. ### Claim 14 (depends on 11) The scan planning apparatus of claim 11, further comprising an interface for selecting one of the first route and the second route, wherein the processing circuitry is configured to select the first route as the lift route when the first route is selected via the interface, and the processing circuitry is configured to select the second route as the lift route when the second route is selected via the interface. ### Claim 15 (depends on 11) The scan planning apparatus of claim 11, further comprising a display configured to display the selected lift route. ### Claim 16 (depends on 11) The scan planning apparatus of claim 11, wherein the bed includes a support frame configured to support the table top such that the table top is slidable in a long- axis direction of the table top, and a base configured to support the support frame such that the support frame is slidable in the long-axis direction and such that the support frame is vertically movable relative to the floor surface, the base is configured to be
