HeartView CT
CoronaryCARE0.5s
Indications:
This is a spiral scanning protocol, using a Rotation
Time of 0.5 s, ECG gating technique and a dedicated
cardiac filter which can reduce images noise thus
makes the dose reduction possible for coronary CTA
studies.
Topogram:
AP, 512 mm.
Approximately, from
the carina until the

A typical range of
12 cm covering the
entire heart can
be done in 18.4 s.
