Assignee: AVATAR MEDICAL
Field: Computer technology (Electrical engineering)
Classification: CPC G  A | IPC A  G

Claim 12:
13. A method of receiving a patient for diagnosis and/or treatment and/or surgery, the method comprising:
generating a 3D model of at least one portion of the patient, each voxel of the 3D model being associated to a respective pixel of at least one corresponding cross-sectional image of the at least one portion of the patient, each cross-sectional image being associated to a corresponding image cross-section plane;
displaying the 3D model to a user in a three-dimensional scene having a corresponding scene coordinate system attached thereto, the three-dimensional scene further including a cursor and at least one display window, each display window lying in a respective display plane having a predetermined equation in the scene coordinate system, each display window being associated to a corresponding window cross-section plane;
computing a current position of the cursor in the scene coordinate system based on a current position of a predetermined user point, attached to the user, in a predetermined user coordinate system;
determining a current observation vector representative of a direction along which the user views the 3D model in the three-dimensional scene;
determining, among said at least one display window, at least one active display window, as the at least one the display window corresponding to a positive value of a scalar product between:
the determined current observation vector; and
a normal vector of the respective display plane oriented opposite the 3D model; and

for each active display window, displaying, on said active display window, a displayed image based on the corresponding cross-sectional image which:
includes a pixel associated to an active voxel which is the voxel having a position that is the closest to the computed current position of the cursor; and
has the corresponding image cross-section plane that matches the window cross-section plane of the active display window; and

providing a diagnosis and/or a treatment and/or a surgical strategy recommendation based at least on a result of navigating the 3D model in the three-dimensional scene by the user.
