What is it about?

The paper illustrate a technique for efficient localization and visualization of wireless medical micro-devices inside the body with Ultrasound imaging. The technique is based on the detection of motions produced by the devices, by exploiting the Doppler effect.

Why is it important?

The proposed strategy allows to enhance the contrast of the target micro-devices and avoid disturbances from background elements and/or imaging artifacts, typically associated to standard Ultrasound imaging. For this reason, the technique provide an efficient feedback strategy which enables precise remote control of wireless medical devices in-vivo. The ability to control such devices holds the potential to revolutionise minimally invasive procedures and diagnoses.
