Harmonics-based in Vivo Optical Virtual Biopsy

Study Purpose

The research aims to study the molecules and structures in human skin by the image formation of harmonic-based in vivo optical virtual biopsy.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Yes
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Interventional
Eligible Ages 18 Years - 90 Years

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT01980264
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

In the research, the investigators use the Cr:forsterite laser as the light source, and utilize the nonlinear optical microscopic system to observe human skin via in vivo detection. In this study, images of human skin tissue will be acquired by virtual section to truly evaluate the feasibility of this system in clinical application. This research intends to conduct the following research: 1. To study the feasibility of this technology to observe melanin in the skin: As melanin is THG-bright, the technology will help to explore the distribution and change of melanin in the skin. 2. To study the capability of this technology in the early diagnosis of skin cancers, including melanoma, basal cell carcinoma, and squamous cell carcinoma: By obtaining skin images of healthy and diseased patients, we can establish an image database of normal and cancerous skin in different atages, and evaluate the efficacy of this technology for early diagnosis of skin malignancy in the future. 3. To study the ability of this technology to observe and analyze the degree of skin aging: Optical sectioning of human skin in a non-invasive in vivo manner can be used to detect the microscopic changes of skin aging and solar damage, and to find out the indicators of skin aging, so as to be used in the future to assist the therapeutic analysis of anti-skin aging treatment. 4. To study the ability of this technology to observe peripheral vasculopathy and molecular changes of microvascular structures in diabetic patients: Perform microscopic imaging on healthy and diabetes patients' skin to observe effects of structures and molecules in their skin, such as peripheral vasculopathy in diabetic patients, and the status of disease parameters, with a view to find the cause of peripheral vascular lesions and other biological information.
