[A/B scan] : The number of A-mode scans per image scanned in
B-mode
[A scan] : Scanning to obtain the depth of the patient’s eye by
radiating light into the eye
[B/C scan] : The number of B-mode scanned images per 3D image
data
[B scan] : Scanning to capture tomographic images by repeating
A-mode scanning while scanning positions linearly on the
patient’s eye
[B-scanned image] : A tomographic image captured by B-mode scan
[C-scanned image] : Tomographic image sliced perpendicular to the depth
direction
[Horizontal image] : A tomographic image sliced in a horizontal direction
[Rotation image] : A tomographic image sliced in an optional direction
[SE] : Equivalent spherical degree (Refer to [Equivalent
spherical degree].)
[VD] : Corneal vertex distance (distance between the corneal
vertex and the posterior surface of the lens)
[Vertical image] : A tomographic image sliced in a vertical direction
[Z-Off]
: Function to automatically align the sight in
up/down/right/left directions
Alignment in back/forth (depth) direction is not conducted.
[Auto Alignment] : Function to automatically align the sight in back/forth
(depth) direction. Automatic alignment in
up/down/right/left directions only can also be conducted
by selecting [Z-Off].
[Auto Shot] : Function that automatically starts measurement when the
patient's eyes are within the measuring range
[Shift Average] : Function to reduce random noise by overlapping and
averaging adjacent tomographic images of a 3D image
