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 2D Window ; see page 151
• Measuring in the M-Mode Window ; see page 165
• Measuring in the Spectral Doppler Modes ; see page 166
• Measuring Vascular Exams ; see page 175
• Measuring Cardiac Exams ; see page 184
• Selecting Measurements ; see page 200
• Deleting Measurements ; see page 201
• Restoring All Measurement Groups to Defaults ; see page 201
• Stress Echo ; see page 202
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
Working with Measurements on an Obstetrical Exam on
page 158.
