Scan Process
MULTI-SCAN
It is difficult for people to maintain perfect stillness during the short period when they are being scanned. To
minimize the variations in measurements due to movement and posture changes, the Size Stream Scanner is
configured to take multiple scans (three is the default) in one continuous sequence. The number of scans
taken for a multi-scan can be changed using the Settings Tool.
Multi-scan produces a raw data image, a refined mesh and an extracted measurement list for each scan in
the sequence. Each will be displayed onscreen as they are processed. In addition, a Composite list of
measurements is also generated. If the multi-scan option is set to 3 or 5 scans, the composite value given for
each measurement will be the median (middle value) of all the values for that measurement. If multi-scan is
set to either 2 or 4, the composite value given will be the average of the two middle values. In multi-scan, the
Custom Measurements will be calculated using the composite measurement values as described above and
the landmarks from the final scan in the sequence.
Note: Pressing the ESC key will abort the processing of the multi-scan sequence. This saves time if the scan is
determined to have errors so a rescan of the subject can occur immediately.
Measurements
MEASUREMENT LIST
The Size Stream Scanner Software processes over 240 measurements. A Measurement Order file can be
chosen to limit this list to only a few key measurements and determine the order in which they are shown. To
select a Measure Order file, point the
Measurement Order File Path setting to the file of your choice. A
demo Measure Order file is provided, as well as an alphabetically sorted list of all available measurements.
This setting is available in the Settings tool. Contact
support@sizestream.com to request assistance with
selecting which measurement will be displayed.
CUSTOM MEASUREMENTS
Custom Measurement functionality is available if your application requires a measurement that is not in the
standard list. Custom Measurements can be created with simple adjustments on the existing measurements.
A sample set of Custom Measurements are included to demo an example use-case.
To obtain a Custom Measurement script specific for your application please send a request to
support@sizestream.com.
A diagram and description of each measurement requested should be included
with your request.
