Provided is a mobile X-ray apparatus which can be manually moved even in a case where a battery is exhausted. The mobile X-ray apparatus according to the present invention is configured to include a motor that drives a driving wheel of a mobile cart via a clutch, a battery that supplies electric power to the motor, a cart manipulation unit that manipulates movement of the mobile cart, and a selector switch that switches between two manipulation states which are a normal manipulation state and a manual manipulation state of the mobile cart. The motor is configured to brake when electric power stops being supplied from the battery. In a case where the manual manipulation state is selected, electric power stops being supplied from the battery to the motor, and the driving wheel and the motor can be controlled so as to be attached to and be detached from each other.

A radiation CT apparatus includes a rotation unit configured to rotate about a rotation axis, a radiation generation unit and a radiation detector which are fixed on either side of the rotation axis in the rotation unit, and a gantry cover containing the radiation generation unit and the radiation detector and including a breast insert portion configured to insert a breast of an object. An opening portion that can be opened and closed is placed on the gantry cover of the radiation CT apparatus. The radiation generation unit and the radiation detector are stopped to form a space that allows a user to access the breast insert portion from the opening portion.

A mobile radiographic imaging system includes a radiation generation apparatus that emits radiation and can be set to a plurality of imaging modes including a first mode for performing fluoroscopic imaging and a second mode that is a general imaging mode and acquires a series of frame images by irradiating a subject with the radiation, and a hardware processor that restricts the use of the first mode outside a management area.

A radiation irradiation apparatus that is configured to independently travel from a decubitus table on which a subject can be placed, the radiation irradiation apparatus including: an attachment portion that allows the radiation irradiation apparatus to be attached to and detached from the decubitus table; a radiation irradiation portion capable of emitting radiation to the subject; a holding portion that is provided at a distal end portion thereof with the radiation irradiation portion and that holds the radiation irradiation portion to be displaceable; and a restriction mechanism that restricts displacement of the holding portion, in which the radiation irradiation apparatus is attached to the decubitus table through the attachment portion to release restriction of the displacement in the restriction mechanism.

A detent method for a medical imaging system. The method comprises obtaining a braking function F(S, V) between a distance S moved by a moveable component of the medical imaging system when a brake is applied to the component and a velocity V of the component and obtaining a measured velocity V.sub.m of the component before the brake is applied. A braking position P.sub.B is determined based on a target position P.sub.T, the measured velocity V.sub.m and the braking function F(S, V), wherein the brake is configured to be actuated when the component reaches the braking position P.sub.B.

A radiation apparatus including a support column, a rotatable arm that is configured to rotate around a first pivot relative to the support column, a first arm rotatably attached to one side of the rotatable arm to rotate about a second pivot, the first arm holding a imaging device, and a second arm rotatably attached to an other side of the rotatable arm to rotate about a third pivot, the second arm holding a radiation source, wherein radiation axis of the radiation source is configured to irradiate an imaging plane of the imaging device.

A mobile x-ray device includes a telescopic column including a fixed portion and an telescopic portion vertically moveable relative to the fixed portion, a telescopic arm moveably connected to the upper telescopic portion of the telescopic column, a head assembly for obtaining x-ray images on the telescoping arm, a wire rope connected to the telescopic portion and the telescoping arm for providing the vertical movement of the telescopic portion and telescoping arm, and a counterbalancing mechanism for balancing the weight of the telescopic portion and the telescopic arm during movement thereof. The counterbalancing mechanism includes a block and tackle connected to the wire rope and a compression spring connected to and extending between the fixed portion and the block and tackle for storing potential gravitational energy of the telescopic portion and telescoping arm during either synchronous or non-synchronous movement of the upper telescopic portion and telescoping arm.

An X-ray installation has a base unit on which a C-arm is arranged. An X-ray source and an X-ray detector are arranged on the C-arm. The C-arm forms half of a closed, convex, point-symmetrical curve. The X-ray source and/or the X-ray detector is/are displaceable along the C-arm. In this way, an angle formed by the X-ray source and the X-ray detector with an isocenter of the full circle is adjustable to a minimum value that is less than 180. Two such X-ray installations can form an X-ray system in which the two X-ray installations are arranged and adjusted such that the closed, convex, point-symmetrical curves of the two X-ray installations form an integrated, closed, point-symmetrical, convex curve and the C-arms of the two X-ray installations form complementary halves of the integrated, closed, convex, point-symmetrical curve.

The present invention relates to a suspension system and an imaging system. The suspension system includes a rotating mechanism, a suspension column, and a carrying apparatus. The rotating mechanism includes a rotating member and a motor unit, and the motor unit is connected to the rotating member and drives the rotating member to rotate. The suspension column is provided with a first accommodating cavity, and the first accommodating cavity is used to accommodate at least a portion of the rotating mechanism. A first end of the carrying apparatus is connected to a bulb tube apparatus of an imaging device, and a second end thereof is connected to the rotating member.

The disclosure concerns a collar device configured for attachment with an image receptor of an X-ray or similar imaging system, the collar device including a radiolucent bar and linear light source, the combination of which being used for patient positioning, identification of surgical entry point and trajectory guidance of instrumentation.
