Fiber optic ultrasound probe

A medical system comprising:

• an ultrasound imaging probe having a first optical fiber integrated therein, wherein:
• the first optical fiber within the ultrasound imaging probe includes a known static reference shape having one or more curves, and
• the known static reference shape defines a reference plane that is disposed in a fixed aligned relationship with an image plane of the ultrasound imaging probe;
• a first elongate member defining a first proximal end and a first distal end, the first elongate member including a second optical fiber extending along the first elongate member from the first proximal end to the first distal end, and the ultrasound imaging probe coupled with the first elongate member at the first distal end,
• wherein the first proximal end is coupled with a system module of the medical system at a defined first endpoint location and the first elongate member extends away from the system module along a defined first direction vector;
• a second elongate member defining a second proximal end and a second distal end, the second elongate member including:
• a third optical fiber extending along the second elongate member from the second proximal end to the second distal end;
• and
• a medical device coupled with the second elongate member at the second distal end,
• wherein the second proximal end is coupled with the system module at a defined second endpoint location and the second elongate member extends away from the system module along a defined second direction vector;
• wherein:
• the first optical fiber includes one or more first core fibers, each of the one or more first core fibers including a first plurality of sensors distributed along a longitudinal length of the first optical fiber,
• the second optical fiber includes one or more second core fibers, each of the one or more second core fibers including a second plurality of sensors distributed along a longitudinal length of the second optical fiber,
• the third optical fiber includes one or more third core fibers, each of the one or more third core fibers including a third plurality of sensors distributed along a longitudinal length of the third optical fiber, and
• each sensor of the first, second, and third pluralities of sensors is configured to (i) reflect a light signal of a different spectral width based on received incident light, and (ii) change a characteristic of the reflected light signal based on strain experienced by each respective core fiber;
• and
• the system module including a console, wherein:
• the first proximal end and the second proximal end are physically coupled with the system module such that the defined first endpoint location and the defined first direction vector are defined with respect to the defined second endpoint location and the defined second direction vector, and
• the console is optically coupled with the ultrasound imaging probe via the first elongate member and the medical device via the second elongate member, the console including one or more processors and a non-transitory computer-readable medium having stored thereon logic that, when executed by the one or more processors, causes operations including:
• providing the received incident light to the first, second, and third optical fibers;
• receiving reflected light signals of different spectral widths of the received incident light from the first, second, and third pluralities of sensors;
• processing the reflected light signals received from the first and the second plurality of sensors to determine a first three-dimensional (3D) shape extending along at least portions of the longitudinal length of the first optical fiber and the longitudinal length of the second optical fiber;
• determining a positioning of the ultrasound imaging probe based at least on the reflected light signals received from the second plurality of sensors;
• processing the reflected light signals received from the third plurality of sensors to determine a second 3D shape extending along at least portions of the longitudinal length of the third optical fiber;
• determining a position of the medical device with respect to the ultrasound imaging probe using the first 3D shape, the second 3D shape, the defined first endpoint location, the defined first direction vector, the defined second endpoint location, and the defined second direction vector;
• determining an orientation of the reference plane based on the reflected light signals received from the first plurality of sensors;
• and
• causing rendering of an image on a display of the medical system in accordance with the positioning of the ultrasound imaging probe and the reference plane, wherein the image includes at least one of an ultrasound image of a patient or a representation of the patient.
