A method for providing guidance for operation of a biopsy 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; generating image data from the reflected ultrasonic sound waves; identifying, by a processor, within the generated image data, at least a portion of a biopsy needle within the interior of the patient; and based at least in part on the identification of the biopsy needle, determining, by the processor, a predicted location of the biopsy needle based at least in part on one or more biopsy needle properties stored in memory operatively connected to the processor; displaying, on a display operatively connected to the processor, an ultrasound image based on the generated image data; displaying, on the ultrasound image, at least one indicator for the predicted location of the biopsy needle; characterized in that the method further comprises steps of: determining a deflection probability for a post-fire needle tip location based on at least one of: experimental data for the type of biopsy needle and one or more stored properties of the biopsy needle, the properties including at least one of a needle length, a needle gauge, a needle wall thickness, a needle material composition, a needle tip geometry, a throw length, and a needle firing mechanism property; and displaying a deflection probability indicator on the ultrasound image, wherein the deflection probability indicator indicates a range for the post-fire tip locations based on the determined deflection probability. 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; generating image data from the reflected ultrasonic sound waves; identifying, by a processor, within the generated image data, at least a portion of a biopsy needle within the interior of the patient; and based at least in part on the identification of the biopsy needle, determining, by the processor, a predicted location of the biopsy needle based at least in part on one or more biopsy needle properties stored in memory operatively connected to the processor; displaying, on a display operatively connected to the processor, an ultrasound image based on the generated image data; displaying, on the ultrasound image, at least one indicator for the predicted location of the biopsy needle; characterized in that the method further comprises steps of: determining a deflection probability for a post-fire needle tip location based on at least one of: experimental data for the type of biopsy needle and one or more stored properties of the biopsy needle, the properties including at least one of a needle length, a needle gauge, a needle wall thickness, a needle material composition, a needle tip geometry, a throw length, and a needle firing mechanism property; and displaying a deflection probability indicator on the ultrasound image, wherein the deflection probability indicator indicates a range for the post-fire tip locations based on the determined deflection probability. determining a deflection probability for a post-fire needle tip location based on at least one of: experimental data for the type of biopsy needle and one or more stored properties of the biopsy needle, the properties including at least one of a needle length, a needle gauge, a needle wall thickness, a needle material composition, a needle tip geometry, a throw length, and a needle firing mechanism property; and displaying a deflection probability indicator on the ultrasound image, wherein the deflection probability indicator indicates a range for the post-fire tip locations based on the determined deflection probability.
