Floor/ceiling mounted kV: Pros and cons

Oblique images: interpretation?

Stereoscopic: very fast acquisition

Bone/marker match

Very low dose?

At some angles, the gantry can block the beam

Fixed system: high stability

Independent from MV source: intrafraction monitoring

No CBCT possibility

Frequent calibrations necessary to check alignment of kV and MV isocentres
