Illustrated Comparison Of CT Scan Modes [axial, Helical, Wide …
In the discussion below we will describe in general the different scan modes at a high level that are used on modern CT systems for general scanning (i.e. a single anatomical CT scan, not fancy temporal stuff). One thing to note however is that there are a variety of terms used to describe the same things by … See more
In modern CT scanners, which are predominately 3rdgeneration CT scanners, there is an Xtube and an x-ray detector mounted on a gantry straight across from one another. These scanners have different scanning modes and the best … See more
The primary difficulty with non-volumetric axial scanning is that when there is patient motion between acquisitions. In this case there can be significant motion between the axial ‘slabs’. This is especially problematic when many slabs are … See more
Even lower pitches are possible on CT systems and, for instance, in traditional cardiac CT scanning, you’re actually using a very low pitch, (eg. a pitch of ~ 0.2). In a separate post later we will discuss the details of ECG gated cardiac and we won’t go into those detail here. The only thing that we want to point out here is that since the cardiac... See more
We discussed pitch 1.0 in the section above and mentioned some reasons to use lower helical pitches. In this section we will describe the opposite scenarios where the desire is to go to pitches larger than 1.0. An extreme case a helical pitch of 2.0 is shown in this figure. At the very center of the gantry (i.e. the iso-center) there is enough data... See more
