kV-CT (a), CBCT (b) and MV-CT (c) of an Alderson head phantom equipped with TTField transducer arrays (Range − 1000 to 3071 HU). In kV-CT and CBCT, bony structures are only visible when they are not within the direct vicinity of TTField arrays and streaky artefacts are present. In contrast, MV-CT is almost free of artefacts, all bony structures are clearly visible and also structures with a low radiographic density, i.e. bore holes, are resolved.
