Abstract
An aspect relates to a placement device for placement in a medium, including: an elongated optical transmission guide to which a photoacoustic transducer is attached to, wherein the photoacoustic transducer may include a first surface facing away from the second end of the elongated optical transmission guide. The photoacoustic transducer may include a 3-Dimensional shape configured to produce an acoustic signal upon absorption of electromagnetic energy received from the elongated optical transmission guide, and an emission profile of the acoustic signal is based on the 3-Dimensional shape, when the photoacoustic transducer is immersed in homogeneous medium. The placement device may be integral to a medical or veterinary device. An aspect relates to a placement tracking system including the placement device and an ultrasound detector. An aspect relates to a method for tracking a portion of a placement device in a medium using the system.
