[Study on detection of changes in tissue structure and composition by using virtual internal hyper-spectrum of body...

Area of Science:

• Biomedical Optics
• Spectroscopy
• Medical Imaging

Background:

• Detecting changes in tissue structure and composition is crucial for medical diagnosis.
• Existing methods may have limitations in simultaneously assessing both structure and composition.
• Non-invasive techniques are highly desirable for early disease screening.

Purpose of the Study:

• To develop and validate a Virtual Internal Hyper-Spectrum of Body Surface (VIHBS) system.
• To assess the capability of VIHBS in simultaneously detecting changes in tissue structure and composition.
• To explore the potential of VIHBS for early diagnosis and screening of human skin conditions.

Main Methods:

• Designed a VIHBS system incorporating modulated light, a translation stage, and a spectrometer.
• Used pork meat samples, with controlled alterations (red filter, intralipid injection) to simulate tissue changes.
• Acquired spectral data at multiple points with controlled spatial resolution.

Main Results:

• Modulated light effectively minimized interference from ambient light and dark current.
• VIHBS successfully located a red filter using visible light.
• The system rapidly screened compositional changes induced by intralipid using near-infrared light.

Conclusions:

• The VIHBS technology is feasible for simultaneously detecting alterations in tissue structure and composition.
• Further research may establish VIHBS as a novel method for early human skin diagnosis and screening.
