Optical coherence tomography system including a planarizing transparent material

1. An OCT (Optical Coherence Tomography) system comprising:

an OCT probe comprising: a body having a distal end and a proximal end; a positioner adapter located at the proximal end; a connector to an OCT analysis device, the connector located at the proximal end, the positioner adapter configured to be held by an arm of a surgical system; a connector configured to receive OCT light from an OCT light source; and, an OCT scan lens located at the distal end, the OCT scan lens configured to focus and scan the OCT light;

a second component comprising: a transparent material configured to planarize tissue at a scan plane of the OCT scan lens, the transparent material being substantially transparent to the OCT light received from the OCT scan lens; and, a handle attached to the transparent material, a respective proximal end of the handle configured to extend through a surgical port, configured for corridor based surgery, such that the transparent material can be manipulated independent of the OCT probe using the handle, the OCT probe and the second component being discrete components, separate from one another, with a space between the transparent material and the OCT scan lens, wherein the handle is configured to be held by a human hand at the respective proximal end such that the transparent material is manipulated by the human hand external to the surgical port to place pressure on the tissue to planarize the tissue;

a navigation system;

a first tracking device located at the proximal end of the body of the OCT probe, the first tracking device configured to be tracked by the navigation system;

a second tracking device located at the respective proximal end of the handle, the second tracking device configured to be tracked by the navigation system; and

the arm of the surgical system, the arm configured to hold the OCT probe using the positioner adapter, the arm in communication with the navigation system, the navigation system configured to cause the arm to position the OCT probe relative to the transparent material to maintain focus at the planarized tissue as the navigation system tracks respective positions of the first tracking device and the second tracking device.

2. The OCT system of claim 1 , wherein a tissue-facing side of the transparent material is substantially flat.

3. The OCT system of claim 1 , further comprising an immersion material on a tissue-facing side of the transparent material, the immersion material configured to physically couple the transparent material to the tissue.

4. The OCT system of claim 1 , further comprising an index matching material on a tissue-facing side of the transparent material, the index matching material configured to optically couple the transparent material to the tissue.

5. The OCT system of claim 1 , wherein a side of the transparent material facing the OCT scan lens is at a non-zero angle to a surface of the OCT scan lens.

6. The OCT system of claim 1 , wherein a distance between the OCT scan lens and the scan plane comprises an OCT scan distance.

7. The OCT system of claim 1 , wherein the transparent material comprises glass.

8. The OCT system of claim 1 , wherein the transparent material comprises plastic.

9. The OCT system of claim 1 , wherein the arm of the surgical system is further configured to position the body relative to the tissue.

10. The OCT system of claim 1 , wherein the body is configured for insertion through the surgical port.

11. The OCT system of claim 1 , wherein a distal end of handle is attached to the transparent material using at least one of: one or more frames; one or more connectors; and epoxy.

12. The OCT system of claim 1 , wherein a distal end of handle includes a 90° bend, the distal end of handle attached to the transparent material.
