System for televised radioscopy

摘要

An assembly for televised radioscopy is described which comprises a source of X-rays, a device for generating a visual signal corresponding to the image of the body organ in motion being examined and a monitor provided with a screen. The assembly comprises a detecting device which has an input to which the visual signal is supplied, at least one output which is intended to be connected to the input of said monitor, a first processing electronic transducer device capable of generating and overlapping a registering signal which is overlapped with the visual signal, the registering signal is capable of causing at least one tracing PR on the televised picture of the monitor, the tracing corresponding to at least one point of the contour of the image of the body organ in motion, the tracing PR having a luminosity different from the luminosity of the surrounding portion. The assembly comprises a second processing electronic device capable of supplying at the output an electric signal indicative of the amount of the displacement of the tracing PR starting from a reference point T which is fixed with respect to the televised picture of the monitor during the movement of the image of the same body organ and display and/or registering means connected to the output of the detecting means and capable of supplying a representation of the displacement of the point of the contour of the body organ being examined.
