Abstract: Aspects of the technology described herein related to modifying the location of an ultrasound imaging plane. Some embodiments include modifying the location of the ultrasound imaging plane based on a user selection. For example, some embodiments include receiving the user selection through a graphical user interface (GUI) that includes an ultrasound imaging plane indicator, where the ultrasound imaging plane indicator indicates the location of the ultrasound imaging plane. As another example, some embodiments include receiving the user selection by detecting tilts, taps, or voice commands. Some embodiments include automatically modifying the location of the ultrasound imaging plane. Some embodiments include modifying the location of the ultrasound imaging plane during biplane imaging.
