Abstract: Electromedical apparatus for intraoperative radiotherapy via a linac. It includes an arm in which, at an extremity thereof, an oscillator is assembled which generates electromagnetic waves, and which supports, at an opposite extremity thereof, a radiating head in which a linac is assembled, emitting at its output an electron beam, supplied by the oscillator through a guiding structure. The apparatus includes a first and a second rotary couplings, respectively including a fixed portion and a mobile portion, endowed with sensors of the angular position of the mobile portions, which support the radiating head on the arm in roll and pitch motion. The guiding structure includes three separate rigid waveguides, of which one at the output of the oscillator and one of input to the linac, and an intermediate one therebetween, which connects them, with the heads of which they are respectively connected through the first and the second rotary couplings.
