Apparatus and method for non-invasive myocardial revascularization

摘要

The present invention relates to an apparatus and method for use with a particle accelerator (10) for effecting non-invasive myocardial revascularization through application of energetic heavy ions. The apparatus accepts a beam of energetic heavy ions from the accelerator and controls the timing and location of delivery of the beam to a treatment region of the myocardium. An electronic gating device (20) is provided for timing the delivery of the beam. A beam nozzle (30) is provided for directing the beam. A beam monitoring device (40) measures the energy, intensity, and position of the beam in the beam nozzle. A heart monitor (50) is provided for synchronizing the gating device to the heart beat. A range modulator (60) may be used to increase the width of the Bragg peak and a delivered-dose monitor (70) may be used for measuring the dose delivered to the target area of the heart.
