Preface
PrefacePhotonics holds a unique position in medical imaging and diagnostics for applications that require functional and/or high-resolution imaging. Current traditional medical imaging modalities such as MRI, ultrasound, PET, and CT primarily offer anatomical images with resolutions above 0.1 mm; however, photonics techniques offer functional sensitivity and subcellular (< 0.001 mm) resolution. Because light interacts with tissue at the molecular level, it provides high molecular specificity and interrogation of tissue function. Light's low-energy, nonionizing photons do not pose toxic exposure risk, allowing nondestructive imaging of living tissue. In addition, optical imaging's subcellular resolution allows examination of tissue and cellular microarchitecture. While this resolution has formed the basis of histopathology for disease diagnosis …
