A-mode ultrasound

In ultrasonography a display in which imaging data are represented as echo amplitudes (on the y-axis) and time (on the x-axis), similar to the way electromagnetic waves are represented on an oscilloscope.
Synonym: A-mode; A-mode (amplitude modulation) display

Therefore, the manual template selection could potentially be eliminated in a real-time implementation with A-mode ultrasound. The advantages of A-mode SMG should also be further verified together with other factors that may affect the collection and extraction of the A-mode SMG signals.
These images enable an investigation of the feasibility of the method and can be used to construct theoretical models describing features of residual muscles for future work using A-mode ultrasound SMG.
EMA: eye muscle area ([cm.sup.2], estimated from A-mode ultrasound scanner)
Although the two-dimensional SMG signal from ultrasound images is capable of detecting continuous muscle thickness changes, A-mode ultrasound, with a more portable and compact transducer, should be a less expensive and more practical alternative for detecting muscle thickness changes during contraction.
