Abstract: The present invention relates to a heart tissue ablation device comprising a charged particle emitting system 1, a control system 2 for instructing the accelerator and beamline when to create the beam and what its required properties should be, a patient positioning and verification system, an ultrasound cardiac imaging system 3 performed on the patient, able to track the target movement, a computer program to determine and record the safe motion margins, the treatment plans for one or more motion phases and a computer program to regulate the control system 2 to load the correct irradiation plan according to the motion phase and if the position of the target is inside of the position margin, the irradiation is enabled and if the position of the target is outside of the position margin, the irradiation is disabled.

Abstract: A medical imaging tool is described, capable of providing in real time 2-D images of the prompt gamma fields released during patient treatment. Owing to its millimetre position accuracy, the instrument is particularly suited for applications where a precise determination of the end-of-range (Bragg peak) of the beam is of paramount importance, as in cancerous and non-cancerous targets for treatment with ion beams and for the treatment of atrial fibrillation. With its unique dual-layer conception in coincidence, the instrument has high rejection ability against false neutron-generated counts, the principal source of background noise for in-beam dose monitoring. It can also provide a coarse measurement of the gamma incidence angle, permitting a correction of the parallax error, main source of dispersion for large area detectors employing collimators.
