摘要： An image registration apparatus comprises: a features detector (34) configured to extract a two-dimensional set of features (36) from a two-dimensional image (30) and to extract a three-dimensional set of features (38) from a three-dimensional image (32); a projection processor (40) configured to project three-dimensional data into two-dimensional projection data; and a registration processor (46, 52) configured to (i) adjust parameters to register the two-dimensional set of features and the three-dimensional set of features projected by the projection processor using a projection geometry (42), and to (ii) use the adjusted parameters to register the two-dimensional image and the three-dimensional image projected by the projection processor using the projection geometry.

摘要： A radiation shield (24) for use with a tomographic scanner (10) provides a shielded region which at which a clinician or other person is shielded from radiation generated during a scan of a patient. A support (20) supports the first radiation shield (24) in a location near the scanner (10). The shield support (20) may be attached to the scanner (10).
