Linear Scans and Encoded C-scans
This optional software feature expands the EPOCH 1000i to a
16:64 element configuration and enables linear scans in addition
to encoded or timed C‑scans. Linear scans are collected using a
probe with up to 64 elements, and a maximum active aperture of
16 elements.
C‑scan imaging is created by accumulating image data from the
programmed linear scan or S‑scan across a single‑line scan axis.
An encoder is required to track the position as the probe is moved
along the scan axis. This encoded C‑scan image collects both time
of flight (TOF) and amplitude data from two independent mea‑
surement gates. The live A‑scan is viewable during C‑scan
acquisition. Compressed A‑scan images can be stored for all
points on the C‑scan, and can be reviewed along with the S‑scan
or liner scan from a particular C‑scan location for basic visual
analysis. Data source and type can be adjusted dynamically after
the scan is acquired, and cursors are available for basic scan
sizing. Additional color palettes are available for phased array
image scans. These color palettes provide different color scales for
use with varied applications, and can be modified to meet your
specific needs.
