Abstract

See full text

Certain implementations of the disclosed technology may include active marker devices, retrofits, systems, and methods for determining the position of interventional devices under MRI. A marker device is provided that utilizes an optical fiber, an acousto-optical sensor region that includes an electro-mechanical conversion assembly, and one or more antenna(e) The one or more antennae are configured to receive MRI radio-frequency (RF) electromagnetic energy and produce a corresponding electrical signal corresponding to the position. The acousto-optical sensor region may include a resonator and may be modulated by acoustic waves generated responsive to the electrical signal received from the one or more antennae The acousto-optical sensor region may be interrogated by light via the optical fiber to determine the position of the device for providing an active marker in the MRI image.
