long axis.
Panorama is available in live B-mode imaging. To acquire a panoramic image:
 Press the Panorama button on the B-mode touchscreen.

After acquisition, the completed Panoramic image is redisplayed to fit on the screen.
Measurements, Comments and Bodymarkers are then supported.

used to obtain the panorama image. If a measurement function in panorama mode is
activated, the caution information of "The accuracy of measurements in Panorama is
limited and can be lower than measurements in B-image" in yellow font color appears
on the bottom of the image and a caution symbol appears on the head of the
measurement results.

Panorama is available only with linear transducers.
