The present invention provides a system for intracranial imaging and treatment of an intracranial region comprising: (a) a catheter probe suitable for insertion into the intracranial region, the catheter probe comprising: (i) a catheter housing; (ii) an optical probe comprising one or more optical emitters; and (iii) an optional surgical tool, wherein the optical probe and the surgical tool are located within the housing; and (b) an imaging plate configured for fixed attachment through a plurality of fixed attachment points to a surface of the intracranial region being imaged and treated, the imaging plate comprising an array of sensors, each sensor comprising an optical receiver. The optical emitters are configured to emit light in proximity to the intracranial region being imaged, and the array of sensors is configured to measure transmitted light to determine the status of the intracranial region being imaged.
