<p>A system for isometric irradiation of target tissue from multiple radiation sources includes a structure supporting an oblique array of radiation sources disposed to rotate about an axis (28) coinciding with the longitudinal axis of a patient, such that individual sources describe non-overlapping trajectories on the surface of the patient. The sources are supported by asymmetric source carrier (24) within relatively limited angular region about said axis. The sources are collimated by selectable sets of apertures (31ai-31di) arranged on mutually independently rotatable rings (30a-30d), each such ring selectably capable of alignment with a sub-array (24a-24f) of sources to produce a variety of patterns and dynamic intensity modulations of the radiation flux.</p> |
