Abstract: In an X-ray examination apparatus, comprising a column, a mount which is connected to the column and which is rotatable about an axis, and a C-shaped carrier which is journalled in the mount, there is provided a friction roller which serves to drive and brake the C-shaped carrier and which bears against a contact face provided along the carrier. The carrier is thus locked in a play-free manner and can be readily adjusted by hand. Because the friction roller is journalled in a carriage which is displaceable with respect to the mount, a pressure exerted on the contact face by the friction roller is adjustable.

Abstract: An X-ray radiographing apparatus includes a power assist device for causing a driving mechanism to generate force for assisting that force which is added to a handle assembly of a spot film device in a direction, so that the spot film device is moved by the sum of both forces in the direction. The movement of the handle assembly is detected by a pressure sensor, so that the detecting signal responsive to the movement is outputted to a control circuit. A driving signal responsive to the detecting signal is supplied from the circuit to the driving mechanism, so that the spot film device is moved in the direction. A component of the weight of the handle assembly is balanced with that of a counter weight, whereby the pressure sensor is prevented from being wrongly operated by the component of the weight of the handle assembly. The width of blind zone of the pressure sensor can be made narrower. The response speed of the spot film device can be made narrower.

In contrast to prior practice in which a film cassette is placed on one side of the patient, an x-ray source on the other, and it is left to the skill of the technician to approximate the necessary alignment, the present invention assures consistent alignment much more precise than is typically achieved. The precise alignment allows regular use of a grid in mobile radiography which helps to prevent image deterioration caused by scattered radiation. The precise alignment is achieved by providing an adaptable physical connection which when in the deployed condition, accurately establishes both the distance between the focal spot and the film plane and the alignment of the grid with respect to the central ray.
