Methods and related systems and devices are described for performing various AR medical applications, including a method of guiding augmented reality (AR) intervention. In one aspect, a primary client device: receives model sets, an intervention plan having an intervention field, and session information about a session related to the AR intervention from a server; receives first real-time input data from a first input device; generates metrics by evaluating an execution of the intervention plan by comparing the intervention plan to the first real-time input data; displays real-time graphics, based at least in part on the metrics, spatially over the intervention field; receives real-time status data, from the server, about a replicate client device that joins the session; sends the first real-time input data, the metrics and the evaluation computed from the intervention plan, through the server, to the replicate client device.

Methods, software and systems for imaging

The invention provides methods for pre- and intra-operatively localizing penile sentinel lymph nodes by injection of fluorescent dyes into penile tumors.

Pre-and-intra-operative localization of penile sentinel nodes

The invention provides both systems and kits for medical imaging of nerves in the head and neck of a subject.

Intra-operative head and neck nerve mapping

A method of determining the patency of a donor organ or at least one vessel to a donor organ in a donor subject includes administering a fluorescent dye to the donor subject, applying a sufficient amount of energy to the vessel such that the fluorescent dye fluoresces, obtaining a fluorescent image of the donor organ or the vessel attached to a donor organ, and observing the image to determine if a fluorescent signal is continuous through the vessel. A continuous fluorescent signal in the donor organ or vessel indicates the respective donor organ or vessel is patent.

Real time imaging during solid organ transplant

A recombination layer with a gradient work function is provided which increases the power-conversion efficiency of multijunction photovoltaic devices by reducing the energy barrier to charge carriers migrating between pairs of photovoltaic junctions thereby facilitating the optimal recombination of opposing electron and hole currents generated when the photovoltaic is illuminated.

Photovoltaic devices with multiple junctions separated by a graded recombination layer

The invention provides methods and systems for imaging vessels in a subject. In certain embodiments the vessels may be associated with a solid organ transplant.

The invention provides methods and systems for neurovascular imaging ().

Method and apparatus for vasculature visualization with applications in neurosurgery and neurology

An entirely passive all-optical device, referred to as an optical hard limiter, includes alternating layers of materials having oppositely signed Kerr coefficients and substantially different linear indices of refraction, wherein the higher linear index material has the negative Kerr coefficient and the lower index material has the positive Kerr coefficient. The optical device has two distinct transmittance curves. Various optical devices and systems can be built from such optical hard limiters.
