Abstract:
1. A medical imaging device comprising: an emission tomograph configured to obtain an emission image of a subject; a transmission source configured to obtain a transmission image of said subject; at least one ultrasonic (US) probe adapted to provide US images giving real-time location information of internal organs of said subject wherein said real-time location information comprises a loci of points (σ(t)); a tracking system adapted to spatially locate the at least one ultrasonic probe in relation to other imaging modalities of the medical imaging device; a US image processing unit adapted to compare real-time location information from said US probe with transmission image information previously obtained from said transmission source, wherein said real-time location information is time-correlated with emission image information from said emission tomograph, and to determine at least one warp parameter indicating a locational difference between an anatomical feature in said previously obtained transmission image and said real-time location information, wherein said determination further uses tracking information from said tracking system; and an image processing unit in which the warp parameter obtained by the US image processing unit is used to modify attenuation correction of emission image information time-correlated with said real-time location information.
