Ultrasound vascular navigation devices and methods

A method of ultrasound scanning, comprising:

• generating a first ultrasound signal by a first ultrasound transducer array of an ultrasound device, wherein the ultrasound device comprises:
• a housing;
• and
• at least one circuit board disposed within the housing,
• wherein the at least one circuit board comprises:
• the first ultrasound transducer array arranged along a first axis of the ultrasound device, wherein the first ultrasound signal is representative of a subject's anatomy along the first axis of the ultrasound device;
• a second ultrasound transducer array arranged along a second axis of the ultrasound device, wherein the first axis is disposed at angle with respect to the second axis;
• a plurality of directional indicators respectively pointing outward from the housing, wherein the plurality of directional indicators are disposed at a plurality of corresponding locations of the housing such that the plurality of directional indicators are spaced from one another;
• and
• a logic circuit in communication with the first ultrasound transducer array, the second ultrasound transducer array, and the plurality of directional indicators,
• wherein the at least one circuit board comprises a first circuit board and a second circuit board parallel to the first circuit board,
• wherein the first ultrasound transducer array and the second ultrasound transducer array are disposed on the first circuit board in an orientation facing the subject's anatomy,
• wherein the plurality of directional indicators are disposed on the second circuit board in an orientation facing the user, and
• wherein the plurality of directional indicators includes light emitting diodes (LEDs),
• generating a second ultrasound signal by the second ultrasound transducer array, wherein the second ultrasound signal is representative of the subject's anatomy along the second axis;
• determining, by the logic circuit, an orientation of the ultrasound device with respect to the subject's anatomy based on the first ultrasound signal and the second ultrasound signal;
• determining, by the logic circuit, if the first axis is unaligned with the subject's anatomy based on the orientation;
• and
• activating, when the first axis is unaligned with the subject's anatomy, a directional indicator of the plurality of directional indicators based on the determined orientation such that the directional indicator that is activated is configured to provide an indication to a user to move a corresponding location of the housing in a direction that the directional indicator points to align the first axis with the subject's anatomy.
