ABSTRACT:
In a system of analysis of an object or a body by means of "transgraphy" i.e. of radiography by transmission, wherein a receiver transducer and a transmitter transducer are linearly and angularly synchronously displaced, the signal supplied by the receiver transducer modulates one characteristic magnitude--intensity or velocity--of the spot of an electronic tube including a charge storage and memory element, while one line scanned by said spot corresponds to a fixed position of the assembly of transmitter and receiver transducers.
