SignificanceThe spatial distribution of the photosensitizing drug concentration is an important parameter for predicting photodynamic therapy (PDT) outcome. Current diffuse fluorescence tomography methods lack accuracy in quantifying concentration. The development accurate monitoring temporal evolution tissue can advance real-time light dosimetry PDT tumors, leading to better treatment outcomes.AimWe develop optical based on interstitial measurements accurately reconstruct fluorescent drugs...

Incorrect pesticide use in plant protection often involve a risk to the health of operators and consumers can have negative impacts on environment crops. The application artificial intelligence techniques help reduction volume sprayed, decreasing these impacts. In Italy, production ready-to-eat salad greenhouses requires usually from 8 12 treatments per year. Moreover, inappropriate sprayers are frequently used, being originally designed for open-field operations. To solve this problem,...

Diffuse Raman spectroscopy (DIRS) extends the high chemical specificity of scattering to in-depth investigation thick biological tissues. We present here a novel approach for time-domain diffuse (TD-DIRS) based on single-pixel detector and digital micromirror device (DMD) within an imaging spectrometer wavelength encoding. This overcomes intrinsic complexity cost detection arrays with ps-resolving time capability. Unlike spatially offset (SORS) or frequency (FORS), TD-DIRS exploits...

Bioresorbable photonic implants are emerging as potential material choice for interstitial theranostic and monitoring applications. They gradually dissolve within the physiological environment in a clinically relevant period, eliminating need extraction surgeries. In present study, we tested suitability of in-house fabricated bioresorbable optical fibres based on calcium phosphate (CaP) glass diffuse correlation spectroscopic (DCS) fluorescence tomographic (DFT) The results represent fibers...

We derive and validate an analytical model that describes the migration of Raman scattered photons in two-layer diffusive media, based on diffusion equation time domain. The is derived under a heuristic approximation background optical properties are identical excitation emission wavelengths. Methods for reconstruction spectra have been developed, tested computer simulations validated tissue-mimicking phantom measurements data. Effects different parameters were studied simulations, showing...
