Latest Patents

Apparatus and Method to Monitor Photodynamic Therapy (PDT). This invention describes a method and apparatus for monitoring photoproducts generated during photodynamic therapy. By tracking a selected photoproduct through an identifying characteristic, such as fluorescence, the system can stop treatment when a predetermined level is reached. This approach is intended to help avoid both excessive exposure that could harm normal tissue and insufficient exposure that could make treatment ineffective.

Spectrometer System for Diagnosis of Skin Disease. This invention uses a light source and probe to illuminate a skin site and collect fluorescence and reflected light. A spectrometer analyzes the collected signals and displays measurements that can assist with diagnosis. The system combines fluorescence and reflectance analysis and is designed as a compact, lower-cost tool using a personal computer and plug-in spectrometer card.

Career Highlights

MacAulay’s patented work focuses on optical technologies for medical treatment and diagnosis. The inventions address two related goals: monitoring treatment response during photodynamic therapy and supporting dermatologic assessment through spectral measurements.
