The imager may be modular, such that a plurality of generally planar imaging surfaces can be used to image various aspects of disease tissue simultaneously. Certain implementations include an angle-selective imager, wherein light from substantially perpendicular to the plane of the imager is received, while incident light is selectively eliminated.

The present disclosure relates to compounds that are useful as near-infrared fluorescence probes, wherein the compounds include i) a pteroyl ligand that binds to a target receptor protein, ii) a dye molecule, and iii) a linker molecule that comprises an amino acid or derivative thereof. The disclosure further describes methods and compositions for incorporating the compounds as used for the targeted imaging of non-small cell lung cancer (NSCLC) in human subjects. Conjugation of the amino acid linking groups increase specificity and detection of the compound. Methods and compositions for use thereof in diagnostic imaging are contemplated.

Systems and methods are disclosed that facilitate obtaining two dimensional (2D) ultrasound images, using two or more ultrasound imaging modes or modalities, to generate 2D multi-parametric ultrasound (mpUS) images and/or to generate a three-dimensional (3D) mpUS image.

The mpUS images (i.e., 2D or 3D) may be used for enhanced detection of suspicious regions.

A device may obtain imaging data. The imaging data that is obtained depicts one or more body parts of a patient. A voltage sensitive dye may be applied to stain nerve tissue associated with the one or more body parts of the patient. The voltage sensitive dye may be activated by neuromodulation applied to stimulate the nerve tissue. The imaging data may capture a fluorescence of the nerve tissue based on the voltage sensitive dye being activated by neuromodulation. The device may provide the imaging data for display.
