Y1 - 2016 N1 - T2 - Anesthesiology Core Review: Part Two Advanced Exam AB - A transesophageal ultrasound probe used for echocardiography can flex forward and backward as well as side-to-side. Imagine the ultrasound beam as flat triangle emitted from the probe. This triangle can rotate 180° around its top point allowing the echocardiographer to view different images or slices of the heart at a particular depth in the esophagus or stomach. The degree of rotation is the “omniplane.” Zero degrees on the omniplane will provide cross-sectional axial images while 90° will provide sagittal images. The omniplane degree is indicated by a semicircle symbol located on the echocardiography image.
