SPIE Paper No. 11220-7

Successful development of a singlet oxygen spectrometer applicable for PDT treatment using a cw laser

Preliminary demonstration during in vivo animal experiments

Continued animal study is ongoing.

Next step will be to reduce the system cost and potentially include time gated measurement capability.

Synchronized, concurrent optical coherence tomography and videostroboscopy for monitoring vocal fold morphology and kinematics

Synchronized, concurrent optical coherence tomography and videostroboscopy for monitoring vocal fold morphology and kinematics

Voice disorders affect a large number of adults in the United States, and their clinical evaluation heavily relies on laryngeal videostroboscopy, which captures the mediallateral and anterior-posterior motion of the vocal folds using stroboscopic sampling.

…
However, videostroboscopy does not provide direct visualization of the superior-inferior movement of the vocal folds, which yields important clinical insight. In this paper, we present a novel technology that complements videostroboscopic findings by adding the ability to image the coronal plane and visualize the superior-inferior movement of the vocal folds. The technology is based on optical coherence tomography, which is combined with videostroboscopy within the same endoscopic probe to provide spatially and temporally co-registered images of the mucosal wave motion, as well as vocal folds subsurface morphology. We demonstrate the capability of the rigid endoscopic probe, in a benchtop setting, to characterize the complex movement and subsurface structure of the aerodynamically driven excised larynx models within the 50 to 200 Hz phonation range. Our preliminary results encourage future development of this technology with the goal of its use for in vivo laryngeal imaging.

Historical Perspective of PDT Light Sources

Y. Zhao, M. Hinds, T. Moritz, J. Gunn, B. W. Pogue, and S. J. Davis
17th International Photodynamic Association World Congress, Cambridge, MA, 3 July 2019
SPIE Paper Number: 11070-174

PDT light sources have advanced from high power discharge lamps to miniature coherent and incoherent fiber-coupled devices.
Progress in these light sources have greatly advanced both our understanding of the PDT mechanisms and kinetics.
Modern light sources are facilitating both laboratory studies and clinical treatments.
