A probe, such as a microscopy probe or a sensing probe, is used to acquire in-vivo imaging/sensing data from the patient. Additionally, the intra-operative and in-vivo images are acquired using tracking and registration techniques to align them with the pre-operative image and the patient to form a composite image for display by the goggle display.

Abstract: In one or more embodiments, the present invention provides am method of making a poly(propylene fumarate-co-succinate) (PPFS) copolymer containing a random incorporation of succinate groups and targetable reduction profiles without the need for three or more monomer units. To achieve this, a time-dependent sonication-promoted zinc/acetic acid reduction of the PPM unsaturated double bonds has been used to create a random PPMS copolymer which may be isomerized into the PPFS equivalent. By changing the sonication time as well as the ratios of acetic acid, zinc, and PPM unsaturated alkenes, partial reduction of the PPM alkenes has been shown to give PPMS products containing varying compositions of succinic and maleate units, which may then be isomerized to the PPFS product.
