1. A method for providing guidance for operation of a needle having an inner member having a sharp tip configured to extend from the needle, the method comprising:
emitting an array of ultrasonic sound waves from an ultrasonic transducer of an ultrasound probe;
detecting reflected ultrasonic sound waves by the ultrasonic transducer, wherein the reflected ultrasonic sound waves include at least a portion of the array of ultrasonic sound waves after being reflected from an interior of a patient and the needle within the interior of the patient;
generating image data from the reflected ultrasonic sound waves;
identifying, by a processor, within the generated image data, at least a portion of the needle within the interior of the patient;
based at least in part on the identification of the portion of the needle, determining, by the processor, a predicted location of the inner member of the needle based at least in part on one or more needle properties stored in memory operatively connected to the processor, the needle properties comprising at least one of a needle length, a needle size, a needle wall thickness, a needle material composition, a needle geometry, and a needle extension mechanism;
displaying, on a display operatively connected to the processor, an ultrasound image based on the generated image data;
determining a deflection probability for an extended inner member location based on at least one of: (1) experimental data for a type of the needle, and (2) the one or more stored properties of the needle; and
displaying a deflection probability indicator on the ultrasound image, wherein the deflection probability indicator indicates a range for the extended inner member location based on the determined deflection probability, wherein the deflection probability indicator depicts a probability distribution for the extended inner member location, and wherein the deflection probability indicator is based at least in part on a standard deviation of the extended inner member location.
