The working and construction of a 27 gauge optical coherence tomography (OCT) imaging needle was demonstrated. The needle enables high resolution internal imaging of any solid tissue or organ with minimal invasion. It is capable of use in combination with standard excisional biopsy devices to reduce sampling errors. The use of a single mode fiber, a GRIN lens and a microprism in the device allows the imaging plane to be controlled with the depth of the needle.
