The invention provides systems and methods for aligning or guiding instruments during image-guided interventions. A volumetric medical scan (image data) of a patient may first be registered to patient space data regarding the patient obtained using a tracking device. An ultrasound simulator fitted with position indicating elements whose location is tracked by the tracking device is introduced to the surface of the anatomy of the patient and used to determine an imaginary ultrasound scan plane for the ultrasound simulator. This scan plane is used to reformat the image data so that the image data can be displayed to a user in a manner analogous to a handheld ultrasound transducer by re-slicing the image data according to the location and orientation of the ultrasound simulator. The location of an instrument fitted with position indicating elements tracked by the tracking device may be projected onto the re-sliced scan data.

A non-invasive screening technique for visualizing coronary arteries which overcomes the problems of visualizing the curved arteries by projecting the three dimensional volume of the arteries onto a two dimensional screen. Blood filled areas, and in particular, the coronary arteries and veins, are highlighted to contrast them with other nearby tissues using non-linear classification and segmentation techniques. Data is gathered as a sequence of 2D slices stored as a 3D volume. Software is employed to interpolate voxels intermediate to the slices. Wiener filtering or LMS spatial filtering can be implemented on each 2D scan to improve lateral resolution and reduce noise prior to the use of the scan data with the classification and segmentation algorithms. A traditional handheld ultrasound probe is employed to enable the technician to locate the area of interest, but a gyroscopic stabilizer is added to minimize unwanted variation on two axes of rotation while scanning through angles on the third axis of rotation.
