Systems and methods include coordinated (KV) and megaelectronvolt (MV)
computerized tomography (CT) imaging. KV and MV data are combined using a
normalization process in order to generate CT images. The resulting CT
images can include an improved signal to noise ratio in comparison to CT
images generated using either KV or MV imaging alone. The coordinated KV
and MV imaging process may be accomplished in significantly less time
than using KV or MV imaging alone. This time savings has advantages in
treatment verification. The MV projections are optionally generated using
MV x-rays configured for x-ray treatment. In these cases the combined
projections will reflect the treatment volume.
