Abstract
Various embodiments include a system and method that provide sequential needle recalibration by correlating a sequence of calibration data for a tracking system to a plurality of corresponding ultrasound probe positions during a calibration sequence such that the appropriate calibration data is retrieved and applied based on the position of the ultrasound probe during a procedure. The method can include acquiring a sequence of calibration data for a tracking system at a plurality of different ultrasound probe positions. The sequence of calibration data may be acquired from a tracking sensor attached to or within the ultrasound probe. The tracking system can include the tracking sensor and a tracking emitter attached to or within a surgical instrument. The method may include generating, by a processor of the ultrasound system, an index correlating each of the sequence of calibration data to a corresponding one of the plurality of different ultrasound probe positions.
