A radiological clip for locating marked tissue within a diagnostic ultrasound image may transmit an ultrasound identification (USID) signal within a bandwidth of ultrasound imaging pulses. A same ultrasound imaging array that receives the ultrasound imaging pulses may also receive the USID signal. An ultrasound imaging apparatus may generate an ultrasound image of the tissue that indicates a location and ID of the radiological clip based on the ultrasound imaging pulses and the USID signal received from the radiological clip within the imaging field. The radiological clip may generate an activation signal in response to receiving an ultrasound imaging pulse, generate an identification signal responsive to the activation signal, and transmit a USID signal based on the identification signal. The USID signal may include encoded signals corresponding to different bits within a multiple-bit identification tag to uniquely identify the radiological clip within a diagnostic image.
