Abstract

A method of and operation for controlling the motions of a radiation source (24) and a radiation detector, for example a film cassette (25), in relation to an adjusted slice position, for example a slice level (19), in a linear tomography apparatus without coupling rod, which tomography apparatus includes a table (10) for accommodating an object (18) to be imaged by tomography includes adjustment of a light indicator (17), adjustably mounted on the table (10), to the position of the slice in the object (18), measurement of data indicating the adjusted slice position, application of the measured slice position data to a system control unit (22), and adjustment of the source (24) and the radiation detector (25) in relation to the measured slice position (19) in conformity with the data applied.
