In vivo diffuse reflectance is used for bone boundary detection. This method is a non-invasive technique that allows for the assessment of bone health without the need for surgical intervention. The technique has shown promise in detecting bone-related disorders and has the potential to improve patient outcomes. Furthermore, it can be used in conjunction with other diagnostic tools to provide a more comprehensive understanding of bone health. The use of in vivo diffuse reflectance for bone boundary detection has the potential to revolutionize the field of bone health assessment and treatment.
