Abstract: The present disclosure provides a system and method for using widely available ultrasound imaging to overcome the limitations of imaging guidewires and other small objects that may be subwavelength in size relative to an ultrasound wavelength. The system and method can reduce the use of X-rays and exposure to the dangerous effects of radiation and avoids the expense of MRI technology. The subwavelength object, such as a guidewire, can be detected using several methods and associated systems described herein, including the object changing positions at a frequency that creates a brighter ultrasound image of the object as the object progresses across a scanned region of the ultrasound detector. In some embodiments, the movement of the small object causes a different speckle signature than the object itself would otherwise generate. Analysis of changes in speckle patterns due to progressive movement of an object can yield a detectable object.
