7 Working With Measurements
Measurements accompanying ultrasound images supplement other clinical procedures
available to the attending physician. Accuracy of the measurements is determined by the
Terason Ultrasound software and by proper use of medical protocols.
When you freeze a scan, the Terason software adds one or two measure tabs to the Image
Control window. For example, if you scanned in M-Mode, a 2D Measure tab and an
M Measure tab display. Each tab provides tools specific to the measurements for the
selected scan mode.
When you save an image, all measurements are saved with the image.
You can create measurements on the currently acquired image (with frames stored
temporarily) or a loaded image or loop if it was saved using the ULT format.
To make measurements on scanned images, you must understand:
•
•
Measuring in the M-Mode Window
•
Measuring in the Spectral Doppler Modes
•
•
•
•
•
Restoring All Measurement Groups to Defaults
•
You can also make measurements on both screens when using Split Screen mode.
To obtain a complete set of measurements, you often have to acquire multiple scans. You
can make as many scans and measurements as needed for the patient without losing any
measurements. Measurements remain on the Image Display window until you:
• Select a different exam
• Select a different scan mode (except for an Obstetrical exam*)
• Load a different patient
* Measurements made in an Obstetrical exam remain on the 2D image when you select a
different scan mode. See
