Abstract: The present disclosure generally relates to optical systems for surgical procedures, and more particularly, to optical relay systems for visualization systems used during ophthalmic microsurgical procedures. The optical systems described herein provide improved ergonomics for surgeons, as such systems facilitate a low-height microscope camera that enables a surgeon to see over the camera to a display screen or other monitor placed in an ergonomically advantageous position for ophthalmic procedures. Such optical systems also provide improved performance, as the total magnification of the optical head may be split between multiple lens barrels, thereby creating high resolution images that enables surgeons to see ophthalmic anatomies more clearly. Even further, such optical systems proffer improved manufacturability, with reduced weight and manufacturing cost, as the lens barrels may have fixed focal lengths for utilization with digital magnification mechanisms.

Abstract: Deployments of software programs to distributed computing environments can be managed according to some aspects described herein. In one example, a system can receive a deployment specification having deployment parameters that define a target deployment state for a software program deployable to a target computing environment. The system can generate, based on a mapping of the deployment parameters to resource consumption values, a resource consumption estimate associated with the target deployment state of the software program in the target computing environment. The system can generate a deployment metric based on the resource consumption estimate and transmit the deployment metric to a client device. The deployment metric can be usable to manage deployment of the software program.

Abstract: These teachings provide for quickly yet accurately forming an influence matrix by generating the influence matrix via integration with a Monte Carlo particle transport simulation. The resultant influence matrix can then be utilized in an ordinary manner when optimizing a radiation treatment plan. By one approach, the foregoing comprises generating the influence matrix via integration with a Monte Carlo particle transport simulation on a particle-by-particle basis. For example, for each particle, these teachings can provide for identifying a spot to which the particle belongs and then adding a dose deposited by the particle during transport to an influence matrix element that corresponds to a spot to which the particle belongs and a voxel to where the dose was deposited.
