CAUTION
The software calculates and displays measurements with a resolution of one
decimal (such as 0.1 mm, 0.1 degree, etc.). You should be aware that the real
measurement accuracy is generally less for a number of different reasons (image
resolution, acquisition conditions…). Distance, angle and area measurements
are valid only if all trace segments are longer than the inter-slice distance.
WARNING
DEPENDING ON WW/WL SETTINGS, OBJECTS MAY DISPLAY
DIFFERENTLY. CHECK WW/WL BEFORE DEPOSITING MEASUREMENT
POINTS.
WARNING
CHECK WITH ORIGINAL DATASETS THE RELIABILITY OF
SEGMENTATIONS AND MEASUREMENTS PERFORMED IN SAVED
OBJECTS AFTER POST PROCESSING AND RELOADING.
14.6 Segment Tools
WARNING
BEFORE USING ANY SEGMENTATION TOOL (THRESHOLD, SCALPEL,
REMOVE & KEEP OBJECT, AUTOSELECT, “FLOATER” FILTERS…), ALWAYS
MAKE SURE THAT IT WILL NOT REMOVE PATHOLOGIES OR OTHER
ESSENTIAL ANATOMICAL STRUCTURES.
WARNING
WHEN USING ANY SEGMENTATION TOOLS (AUTOSELECT, THRESHOLD,
PAINT ON SLICE, QUICK PAINT…), CHECK CONTOURS TO CHECK THE
RELIABILITY OF THE SEGMENTATION. MAKE SURE THE CONTOURS
MATCH THE CORRECT SEGMENTATION AND VOLUMES. CHECK THAT
THE SEGMENTED VOLUMES MATCH THE CONTOURS.
14.7 Filming and Saving Images
CAUTION
The formats and image quality of exported electronic films are not suitable for
diagnostic purposes. Image quality may be degraded by data compression
techniques used to export electronic films.
CAUTION
When filming or saving images for diagnostic purposes, always make sure the
patient name and geometry information is displayed on all views, and that they
match the information on the reference view.
