1. An apparatus for detecting and monitoring intracranial fluid in a subject, the apparatus comprising:
three fixed contact points defining a plane, each said contact point being configured to contact a curved surface bounding a volume to be imaged;
an array of at least three co-planar electromagnetic transceivers defining a receiving plane;
at least one deformable electromagnetic emitter moveable orthogonally to the receiving plane and the plane defined by the three fixed contact points, wherein the at least one deformable electromagnetic emitter is configured to contact the curved surface bounding the volume to be imaged;
a two-dimensional (2D) position tracking device configured to track a position of the apparatus in x-y coordinates while moving on the curved surface bounding the volume to be imaged; and
a displacement sensor configured to measure deformation of the at least one deformable electromagnetic emitter moving on the curved surface;
wherein the electromagnetic emitter and transceivers are configured to generate optical density data relating to presence or absence of the intracranial fluid from at least three depths below the curved surface, wherein the optical density data is for use in creating an image of the volume as the apparatus is moved along the curved surface;
wherein the local curvature of the curved surface is determined by orthogonal displacement of the deformable electromagnetic emitter relative to the plane defined by the three fixed contact points; and
wherein the local curvature of the curved surface is correlated to the position of the apparatus as measured in x-y coordinates.
