A system and method (i.e, utility) are disclosed for positioning a needle in three-dimensions based on patient related statistics for extracting tissue during biopsy procedures. Aspects of the utility can be applied independently or serve as an aid to the urologist when regions of interest are hard to discern in an ultrasound image. Regions of interest that correspond to high cancer risk regions (e.g., statistically) are automatically superimposed on an ultrasound image of a patient in real time. Additionally a statistical map based on one or more demographic parameters of a patient and containing cancer probability locations are also automatically mapped on the ultrasound image in real time displaying potential cancer locations. Aspects of the system are also capable of displaying optimal needle placement positions based on statistical priors and will be able to accurately navigate the needle to that position for biopsy extraction and / or treatment.

Method for registering and merging medical image data
ActiveUS20050245807A1Accurate guideMaximizing similarityImage enhancementImage analysisData setSuperimposition
The present invention relates to a method for the registration and superimposition of image data when taking serial radiographs in medical imaging, wherein a plurality of image data sets for a region of a patient (17) that is being investigated are constructed at time intervals using an imaging system (1) and are referenced with a first image data set for the region that is being investigated that was constructed previously using said imaging system (1). In the above method, a location system (2) is used during the production of serial radiographs constantly, or at least at a respective proximity in time to the construction of individual data sets, to determine a current spatial position of the region being investigated in a reference system that is firmly connected to the imaging system (1), whereby in the construction of the first image data set, a first spatial position of the region that is being investigated is recorded. In the construction of some or all further image data sets, the respective current spatial position of the region that is being investigated is determined and an image content of each first image data set is geometrically adapted on the basis of the difference between the first and the current spatial position, such that compensation is made for a different spatial position of the region that is being investigated. The geometrically adapted first image data set or an image data set derived therefrom, or an image data set that is positionally connected thereto by registration is then displayed superimposed with the respective further image data set.

Next, the system creates feature vectors from coefficients generated by the feature-detection operation, wherein each feature vector comprises a set of coefficients for sound features detected in a window. The system then performs a clustering operation on the feature vectors to produce feature-vector clusters, wherein each feature-vector cluster comprises a set of feature vectors that are proximate to each other in a feature-vector space that contains the feature vectors. After the clustering operation, the system defines a set of sound primitives, wherein each sound primitive is associated with a feature-vector cluster. Finally, the system associates semantic labels with the set of sound primitives.
