Method and system for guiding a diagnostic or therapeutic instrument towards a target region inside the patient's body
First Claim
1. A medical imaging system, comprising:
- a rigid frame, which includes;
fittings for snugly securing said frame to a patient'"'"'s body; and
at least three fiducial marks, arranged at different locations, on said frame;
a three-dimensional, first structural imaging modality, adapted for imaging different densities within the patient'"'"'s body and adapted to detect said at least three fiducial marks, for defining a three-dimensional coordinate system;
a three-dimensional, first functional imaging modality, adapted for imaging radioactively tagged pharmaceuticals, injected to the patient and distributed in the patient'"'"'s body due to physiological activities, thus adapted to detect said target, wherein said first functional imaging modality is spatially registered to said three-dimensional coordinate system; and
a computer device, for receiving input from said first structural and functional imaging modalities and for simultaneously displaying both, superimposed.

Abstract
Method and system are presented for guiding a diagnostic or therapeutic instrument towards a correct target inside the patient'"'"'s body. A combined image obtained by registering structural and functional images of at least a portion of the patient'"'"'s body including the target is used together with a guiding device. The guiding device has an indicator associated with the instrument, and is operable for presenting data indicative of a position of a location on the instrument relative to any other point in the at least portion of the patient'"'"'s body. The guiding device is connectable to a computer device displaying the combined image and operable thereby for guiding the instrument towards the target.

37. A system for guiding an instrument towards a target inside a patient'"'"'s body, said system comprising:
-
a rigid frame, which includes;
fittings for snugly securing said frame to the patient'"'"'s body; and
at least two fiducial marks, arranged at different locations, on a plane of said frame;
a two-dimensional, first structural imaging modality, adapted for imaging different densities within the patient'"'"'s body and adapted to detect said at least two fiducial marks, for defining a two-dimensional coordinate system;
a two-dimensional, first functional imaging modality, adapted for imaging radioactively tagged pharmaceuticals, injected to the patient and distributed in the patient'"'"'s body due to physiological activities, thus adapted to detect said target, wherein said first functional imaging modality is spatially registered to said two-dimensional coordinate system;
