Disclosed herein are methods of vascular and structural imaging using imaging systems and methods described, the methods comprising producing an image of the vasculature or structure by imaging fluorescence using an imaging system, the system comprising: i) one or more detectors configured to form a fluorescence image of the sample and form a visible image of the sample; ii) a light source configured to emit an excitation light to induce fluorescence from the sample; and iii) a plurality of optics arranged to: direct the excitation light toward the sample; and direct a fluorescent light and a visible light from the sample to the detector; wherein the excitation light and the fluorescence light are directed substantially coaxially.
HIGH THROUGHPUT SNAPSHOT SPECTRAL ENCODING DEVICE FOR FLUORESCENCE SPECTRAL MICROSCOPY
Systems and methods are provided for multi-spectral or hyper-spectral fluorescence imaging. In one example, a spectral encoding device may be positioned in a detection light path between a detection objective and an imaging sensor of a microscope. In one example, the spectral encoding device includes a first dichroic mirror having a sine transmittance profile and a second dichroic mirror having a cosine transmittance profile.

Adaptive illumination apparatus, method, and applications
A system and method for adaptive illumination, the imaging system comprising an excitation source having a modulator, which generates a pulse intensity pattern having a first wavelength when the excitation source receives a modulation pattern. The modulation pattern is a data sequence of a structural image of a sample. An amplifier of the imaging system is configured to receive and amplify the pulse intensity pattern from the modulator. A frequency shift mechanism of the imaging system shifts the first wavelength of the pulse intensity pattern to a second wavelength. A laser scanning microscope of the imaging system receives the pulse intensity pattern having the second wavelength.
Fluorescence lifetime spectroscopy based capsule endoscopy
An ingestible capsule for detecting cancerous and non-cancerous tissues in a colon of patient is disclosed. The capsule has a radiation source integrated into the capsule body for illuminating tissues within a colon of the patient. Tissues of the colon are irradiated with radiation from the radiation source to elicit a fluorescence response, and a photon detector measures photons of the fluorescence response. Intensity and fluorescence lifetime of the fluorescence response is determined based on measured photons. A system employing the capsule is configured to distinguish cancerous and non-cancerous tissues based on the determined fluorescence lifetime of the fluorescence response.
Multi-modal image-guided radiation system
Systems and methods relate to multi-modal imaging of tissue combined with highly focused radiation interventions. The system is a portable multimodal imaging unit that integrates imaging and image analysis. The system can be retrofitted to use with any commercial radiation therapy machine. In one aspect, a system integrates various imaging modalities into a single, coordinated structure. The system integrates X-ray and cone beam computed tomography (CBCT), optical imaging (such as bioluminescent imaging (BLI), fluorescence tomography (FT)), and positron emission tomography (PET) imaging in a single, self-contained structure.
DEVICES, SYSTEMS, AND METHODS FOR FLUORESCENCE IMAGING
Devices, systems, and methods perform optical-scanning operations to acquire fluorescence data values corresponding to fluorescence data collected from inside a bodily lumen. A processor receives the fluorescence data; calculates a threshold background fluorescence value based on a central tendency of at least part of the fluorescence data values; discards fluorescence data values that are lower than the threshold background fluorescence value, thereby creating corrected fluorescence data values; and generates an image of the bodily lumen based on the corrected fluorescence data values.
Methods for monitoring physiological status of a body organ
The present invention provides method for monitoring physiological status of an organ in a subject by monitoring morphological changes over time in transplanted tissue on an eye of the subject.
METHODS, APPARATUSES, AND SYSTEMS FOR INDUCTIVE HEATING OF FOREIGN METALLIC IMPLANTS
Methods, apparatuses, systems, and implementations for inductive heating of a foreign metallic implant are disclosed. A foreign metallic implant may be heated via AMF pulses to ensure that the surface of the foreign metallic implant heats in a uniform manner. As the surface temperature of the foreign metallic implant rises, acoustic signatures may be detected by acoustic sensors that may indicate that tissue may be heating to an undesirable level approaching a boiling point. Once these acoustic signatures are detected, the AMF pulses may be shut off for a time period to allow the surface temperature of the implant to cool before applying additional AMF pulses. In this manner, the surface temperature of a foreign metallic implant may be uniformly heated to a temperature adequate to treat bacterial biofilm buildup on the surface of the foreign metallic implant without damaging surrounding tissue. The AMF pulse treatment can be combined with an antibacterial/antimicrobial treatment regimen to reduce the time and/or antibacterial dosage amount needed to remove the biofilm from the metallic implant.
