Scan Acquisition Protocols
4-7
Fast Macular Thickness Map (Fast Mac)
The Fast Macular Thickness Map (Fast Mac) protocol combines the six Macular
Thickness Map scans into one scan (see page 4-7). This protocol acquires six 6 mm
radial line scans in 1.92 seconds of scanning. You ca
nnot alter the size or number of lines.
This retina protocol is designed for use with the retinal thickness analyses.
Macular Thickness Map
The Macular Thickness Map protocol is a version of the radial lines pattern. It consists of a
series of 6 to 24 equally spaced line scans through a common central axis. The diameter of
the aiming circle (and thus line length) is fixed at 6 mm. The number of lines is adjustable
until you save the first scan in the series. This protocol is designed for use with the analyses
that measure retinal thickness.
Fast RNFL Thickness (3.4)
The Fast RNFL Thickness (3.4) protocol combines the three RNFL Thickness (3.4) circle
scans into one scan (see page 4-8). This protocol acquires three 3.4 mm diameter circle
scans in 1.92 seconds of scanning. You cannot alter
the size of the circles. This glaucoma
protocol is designed for use with the RNFL thickness analyses.
Fast Optic Disc
The Fast Optic Disc protocol combines the six Optic Disc scans into one scan (see page
4-10). This protocol acquires six 4 mm radial line scans in 1
.92 seconds of scanning. You
cannot alter the size or number of lines. This glaucoma protocol is designed for the optic
ne
rve head analysis.
Line
Select Line to acquire multiple line scans without returning to the MAIN WINDOW. The
default pattern is a horizontal line (0°) of length 5mm. You can adjust the length, angle
and placement of each scan. This general-purpose protocol enables you to acquire multiple
line scans, each of which you can repeat or tailor individually. You can average same-size
scans in later analysis. You can also use this scan to build a custom protocol.
Cross Hair
The Cross Hair protocol consists of two perpendicular line scans that intersect at their
centers to form a cross. This protocol is useful to examine a particular point of clinical
interest in slices through the centers of the four quadrants. The default line scan is 3 mm
long. You can adjust scan length by adjusting the height (affects vertical line) and width
(affects horizontal line) before saving the first scan. After you save the first scan, you
cannot make further adjustments.
Radial Lines
The Radial Lines protocol consists of a series of 6 to 24 equally spaced line scans through a
common central axis, like spokes on a wheel. It is a general-purpose pattern that is
