Feature Of The Week 5/13/12: Polytechnique Montreal Researchers Investigate the Use of Optical Coherence Tomography for Guiding Treatment of Musculoskeletal Diseases such as Scoliosis
Researchers from the Polytechnique Montreal University develop an experimental intra-operative optical coherence tomography based endoscope imaging system to precisely guide the insertion of hemi-staples that are are inserted on the growth plate to locally control vertebral growth to treat adolescent idopathic scoliosis. Below is a summary of their work.
Adolescent idiopathic scoliosis (AIS) is a complex three-dimensional deformity of the spine requiring in severe cases invasive surgery. Here, we explore the potential of optical coherence tomography (OCT) as a guiding tool for novel fusionless minimally invasive spinal surgeries on an ex vivo porcine model. We show that OCT, despite its limited penetration depth, may be used to precisely locate structures such as growth plate, bone and intervertebral disk using relative attenuation coefficients. We further demonstrate a segmentation algorithm that locates growth plates automatically on en-face OCT reconstructions.
