Advances in Stimulated Raman Scattering Microscopy via Deep Learning
Stimulated Raman scattering (SRS) microscopy is a powerful chemical imaging technique that acquires images based on the vibrational-spectral “fingerprints” of molecules within an imaged field of view often without the need for exogenous fluorophores or labels. SRS microscopy has found an …

Hot particle dosimetry using a wall-less tissue equivalent proportional counter
… operations such as refurbishment and decommissioning or from a severe nuclear accident. If deposited on the skin, ingested or inhaled, hot particles can pose a significant radiological hazard. Typically, hot particles are beta particle or alpha particle emitters and deposit their energy over very …

Measurement of tissue optical properties during mechanical compression using swept source optical coherence tomography
Laser-based photo-thermal therapies can provide minimally-invasive treatment of cancers. Their effectiveness is limited by light penetration depth in tissue due to its highly scattering properties. The highly disordered refractive index distribution in tissue leads to multiple-scattering of …

Spectrally Resolved Detector Arrays for Multiplexed Biomedical Fluorescence Imaging
… emissions from different biological targets in video rate applications, such as endoscopy and intraoperative imaging, has traditionally been limited by the use of filter-based imaging systems. Hyper and multispectral imaging facilitate the detection of both spatial and spectral information in …

Improving ultrasound display by retrieving high-frequency sonographic information
"The ability of an ultrasound system to distinguish between two points along the direction of pulse propagation at a certain depth in tissue is denoted as the axial resolution of the system, which is an important factor in image quality. The axial resolution of ultrasonic B-mode images has been …

Photoacoustic Microscopy and Photoacoustic Computed Tomography Using High-frequency Linear Array Ultrasonic Transducers
… tomography (PAT) is a highly promising imaging technology which forms images by detecting the induced pressure waves resulting from pulsed light absorption in biological tissues. Because the excitation source is light, PAT is a very safe, non-ionizing, and non-carcinogenic imaging …

Monte Carlo Analysis and Physics Characterization of a Novel Nanoparticle Detector for Medical and Micro-dosimetry Applications
… for both (i) radiation therapy and (ii) preclinical small animal radio- biology studies are dependent on the delivery of a known quantity of radiation to a specific and intentional location. Adverse effects can result from these procedures if the dose to the target is too high or low, and can …
