Ultrasound image-based guidance of medical instruments or devices

A method comprising:

• controlling an ultrasound transducer array to transmit third ultrasound energy in a third direction different than a first direction and a second direction and receive third reflected ultrasound energy in a third field of view of a region of patient anatomy based at least in part on reflection of the third ultrasound energy;
• detect an obstruction in the third reflected ultrasound energy in the third field of view;
• controlling, based on detecting the obstruction in the third reflected ultrasound energy, the ultrasound transducer array to transmit first ultrasound energy in the first direction and transmit second ultrasound energy in the second direction at a same time and to cease transmitting the third ultrasound energy in the third direction, wherein the second direction is different than the first direction;
• controlling the ultrasound transducer array to receive first reflected ultrasound energy in a first field of view of a region of patient anatomy based at least in part on reflection of the first transmitted ultrasound energy and receive second reflected ultrasound energy in a second field of view of the region of patient anatomy based at least in part on reflection of the second transmitted ultrasound energy, wherein the second field of view is different than the first field of view;
• and
• generating one or more ultrasound images based on the first reflected ultrasound energy and the second reflected ultrasound energy.

Non-transitory computer-readable media comprising instructions to cause one or more processors to:

• control an ultrasound transducer array to transmit third ultrasound energy in a third direction different than a first direction and a second direction and receive third reflected ultrasound energy in a third field of view of a region of patient anatomy based at least in part on reflection of the third ultrasound energy;
• detect an obstruction in the third reflected ultrasound energy in the third field of view;
• control, based on detecting the obstruction in the third reflected ultrasound energy, an ultrasound transducer array to transmit first ultrasound energy in the first direction and transmit second ultrasound energy in the second direction at a same time and to cease transmitting the third ultrasound energy in the third direction, wherein the second direction is different than the first direction;
• control the ultrasound transducer array to receive first reflected ultrasound energy in a first field of view of a region of patient anatomy based at least in part on reflection of the first transmitted ultrasound energy and receive second reflected ultrasound energy in a second field of view of the region of patient anatomy based at least in part on reflection of the second transmitted ultrasound energy, wherein the second field of view is different than the first field of view;
• and
• generate one or more ultrasound images based on the first reflected ultrasound energy and the second reflected ultrasound energy.
