The deep tissue penetration and submicron spatial resolution of multiphoton microscopy and the high detection efficiency and nanometer spectral resolution of a spectrograph were utilized to record spectral images of the intrinsic emission of mouse skin tissues. Autofluorescence from both cellular and extracellular structures, second-harmonic signal from collagen, and a narrowband emission relat...
Laser Scanning Microscopy Techniques such as Confocal Microscopy, Two Photon Excitation Microscopy, Second Harmonic Generation Microscopy or Fluorescence Lifetime Imaging have been successfully employed to date for imaging skin cancer. However, the resolution that such techniques can provide is limited by diffraction, which prevents accurately imaging (and differentiating) optical details sized...
2 Introduction The assessment of left ventricular function is one of the most clinically important and frequently requested tasks in echocardiography. We are witnessing a progressive development in echocardiographic methods and techniques including the use of higher frequency transducers, tissue Doppler, harmonic imaging and trans-pulmonary or left sided contrast agents.
Laser thermal injury and subsequent wound healing in organotypic, skin-equivalent tissue models were monitored using optical coherence tomography (OCT), multiphoton microscopy (MPM), and histopathology. The in vitro skin-equivalent raft tissue model was composed of dermis with type I collagen and fibroblast cells and epidermis of differentiated keratinocytes. Noninvasive optical imaging techniq...
Besides being a physical scaffold to maintain tissue morphology, the extracellular matrix (ECM) is actively involved in regulating cell and tissue function during development and organ homeostasis. It does so by acting via biochemical, biomechanical, and biophysical signaling pathways, such as through the release of bioactive ECM protein fragments, regulating tissue tension, and providing pathw...
The objective of this study is to show that Harmonic Motion Imaging (HMI) can be used as a reliable tumor-mapping technique based on the tumor's distinct stiffness at the early onset of disease. HMI is a radiation-force-based imaging method that generates a localized vibration deep inside the tissue to estimate the relative tissue stiffness based on the resulting displacement amplitude. In this...
