Method for ultrasound guidance during clinical procedures
First Claim
1. A method for generating quasi real-time feedback information about tissue characteristics and the position of anatomical objects relative to at least one tool used during clinical procedures in living biological structures, employing an ultrasound transducer and comprising:
- acquiring at least one 2D and/or 3D ultrasonic image of anatomical objects in a living biological structure during a clinical procedure,freely moving said at least one tool and/or said ultrasound transducer,localizing said at least one tool and/or tool trajectory thereof in an imaged scene covered by said ultrasonic image,computing visualizations of the imaged scene by utilizing the geometric localizations of said at least one tool in the processing and/or visualization of said ultrasonic images, anddisplaying the resulting visualizations on a display unit in order to provide quasi real-time feedback to the operator.

Abstract
A method for generating quasi-realtime feedback for the purpose of guiding surgical, therapeutic or diagnostic procedures by means of ultrasound imaging, wherein the location of a surgical tool, therapeutic radiation field or a diagnostic energy field is related to the coordinate system of an intraoperative 2D and/or 3D ultrasound imaging system and, optionally, to pre-operative MR/CT/X-ray data, thus allowing synchronized relations between data acquisition, tool movement and image visualizations.

17. A method for generating quasi real-time feedback information about tissue characteristics and the position of anatomical objects relative to at least one tool used during clinical procedures in living biological structures, employing an ultrasound transducer and comprising:
-
acquiring at least one 2D and/or 3D ultrasonic image of anatomical objects in a living biological structure during a clinical procedure, freely moving said at least one tool and/or said ultrasound transducer, controlling ultrasonic viewing scan plane selection by the position and orientation of the at least one tool so as to retain viewing of the at least one tool superimposed into the scan plane while the at least one tool is moved relative to the ultrasound transducer, localizing said at least one tool and/or tool trajectory thereof in an imaged scene covered by said ultrasonic image, computing visualizations of the imaged scene by utilizing the geometric localizations of said at least one tool in the processing and/or visualization of said ultrasonic images, and displaying the resulting visualizations on a display unit in order to provide quasi real-time feedback to the operator.

18. Apparatus for generating quasi real-time feedback information about tissue characteristics and the position of anatomical objects relative to at least one tool used during clinical procedures in living biological structures, employing an ultrasound transducer and comprising:
-
means for acquiring at least one 2D and/or 3D ultrasonic image of anatomical objects in a living biological structure during a clinical procedure, means for freely moving said at least one tool and/or said ultrasound transducer, means for localizing said at least one tool and/or tool trajectory thereof in an imaged scene covered by said ultrasonic image, means for computing visualizations of the imaged scene by utilizing the geometric localizations of said at least one tool in the processing and/or visualization of said ultrasonic images, and means for displaying the resulting visualizations on a display unit in order to provide quasi real-time feedback to the operator.
