Content Item Descriptions

Row 1

The depth represents the distance from the transducer face to the center of the ROI and is typically determined by time-of-flight.

Row 3

The ROI is typically a circle or square, although other shapes are permitted.

For measurements taken in point shear wave elastography image mode measurements, the measurement data is collected over some amount of adjacent tissue, but the region is indicated with a POINT ROI.

Rows 4, 8, 12

The value represents the mean value of the pixels contained in the ROI.

Rows 5, 9, 13

The value represents the standard deviation of the values of the pixels contained in the ROI. If the ROI is a point, the standard deviation is zero. If the ROI has a very small number of pixels, the standard deviation value might not be statistically meaningful.

Rows 6, 10, 14

The value represents the minimum value of the pixels contained in the ROI.

Rows 7, 11, 15

The value represents the maximum value of the pixels contained in the ROI.
