[Tomoscopy].

UNLABELLED

Report on initial clinical experience with a new form of tomography with fluoroscopy, called 'tomoscopy'.

PRINCIPLE

Several grid controlled x-ray tubes firmly mounted (stationary) in circular fashion -- with the foci in equidistance -- are fired in sequential fashion for a short exposure, which creates the impression of tube movement mandatory in conventional tomography, by this sequential firing of several tubes (in 1/50 second total), the mechanical tube motion of conventional tomography can be avoided. In the image intensifier, there is synchronous electromagnetic deflection of the image between input- and output screen; and a tomographic image can be seen at the output screen. This can also be recorded on camera. This new technique allows quick fluoroscopic determination of the ideal 'cut' and thus provides efficient tomography without slowing down the ongoing examination; and it is a useful addition to modern radiographic equipment with image intensification, especially when used with contrast material. Its full future impact on diagnostic radiology can yet not be estimated.
