Co-localization of the RCM/OCT images, imaging depth, sensitivity decay within the imaging range, field of view (FOV), and imaging resolution were measured.
The graphs show similar noise levels for the simulated images compared with the actual acquisition over the whole imaging range.
Table 1 Recommended imaging range and ECG synchronisation depending on the congenital heart disease type Congenital heart disease type Imaging range ECG synchronisation required?
Due to the limitation of the imaging range of this system, we only acquired the retinal microstructural images at two depth locations (1 mm and 2 mm, respectively).
Typical photon energies in SPECT imaging range from 50 to 400 keV.
The imaging range was from the vertex to the upper thighs.
A recent study observed that, by minimisation of the imaging range in cardiac CT, 0.7 mSv for each centimetre of the imaging range lost can be saved in adults when using a retrospective ECG-gated technique [18].
Contrast extravasation rates during CT imaging range between 0.1 and 0.9 %, with an average rate of 0.4%[1314] 14].

One has to bear in mind that the CT radiation dose is directly proportional to the imaging range when all other acquisition parameters are similar, and that ECG-synchronised cardiac CT has the highest radiation dose per centimetre imaging range of all CT protocols.
