Medical x-ray imaging apparatus

A medical x-ray imaging apparatus comprising:

• a support construction supporting a substantially ring-shaped structure including imaging means, said imaging means comprising a source of radiation and a receiver of image information, the imaging means and the receiver of image information being located substantially on opposite sides of each other and movable within said ring-shaped structure,
• said ring-shaped structure defining an examination opening wherein the object to be imaged is positionable,
• said ring-shaped structure being movable in at least a vertical direction with respect to said support construction,
• a positioning support located within said examination opening, said positioning support being adjustable with respect to said ring-shaped structure, and
• the apparatus further including a control system for moving said positioning support within the area of the examination opening by a means of at least one actuator in a first direction at a first speed while simultaneously moving said ring-shaped structure substantially at said first speed in a direction substantially opposite to said first direction.

A medical x-ray imaging apparatus, which apparatus includes

• a support construction which is arranged to support a substantially ring-shaped structure supporting imaging means, which imaging means include a source of radiation and a receiver of image information, which imaging means are arranged within said substantially ring-shaped structure supporting the imaging means substantially on opposite sides of each other and movable within said substantially ring-shaped structure supporting the imaging means,
• an examination opening within which an object to be imaged is positionable for imaging the examination opening being formed in said substantially ring-shaped structure supporting the imaging means,
• wherein said substantially ring-shaped structure supporting the imaging means is arranged movable with respect to said support construction at least in the vertical direction,
• wherein a positioning support is connected to a wall forming said examination opening and whose location with respect to said substantially ring-shaped structure is arranged adjustable, and wherein an actuator is disposed on or partially within said substantially ring-shaped structure.
