A new automated method for spectral background estimation in laser spectroscopy ensures the accuracy of quantitative analysis with minimal human intervention.When using laser-induced breakdown spectroscopy in spectral analysis, scientists may encounter various obstacles. The most common challenge faced by scientists when conducting elemental analysis is to optimize the interaction between the lase...
Photoacoustic tomography (PAT) is a novel hybrid medical imaging technique that enables precise imaging of biological tissue structures at different spatial scales. It has been widely used in various fields, including brain imaging, cancer detection, and cardiovascular disease diagnosis. However, due to limitations in data acquisition conditions, photoacoustic tomography systems typically can only...
