A frame (A) of a diagnostic imaging device such as a CT scanner or an MRI device has a bore defining a patient examination region ( ). A first x-ray source (B) is mounted to a frame (C) for rotation around the examination region ( ). An arc of first radiation detectors ( ) detects x-rays which have traversed the examination region. A first image reconstruction processor ( ) reconstructs a tomographic image representation from signals generated by the first radiation detectors. A fluoroscopy device (D) is mechanically coupled to the diagnostic scanner for generating and displaying at least substantially real-time fluoroscopic projection image representations on a display monitor ( ). A second x-ray source ( ) transmits x-rays to an amorphous silicon flat panel radiation detector ( ). A second image reconstruction processor ( ) reconstructs the fluoroscopic projection image representations from signals generated by the flat panel radiation detector ( ). A C-arm ( ) supports the second x-ray source ( ) and the flat panel radiation detector ( ) in a plane offset from a plane of the C-arm. A movable mounting structure (E) is mechanically connected with the gantry (A) and the C-arm ( ) to move the C-arm between a stored position and an operating position adjacent the bore.

Fluoro-assist feature for a diagnostic imaging device

A patient supported on a patient support (12) is moved into a bore (22) of a planning imaging device, such as a CT scanner (20). A three-dimensional diagnostic image in three-dimensional diagnostic image space is generated and stored in a memory (130). The patient is repositioned outside of the bore with a region of interest in alignment with a real time imaging device, such as a fluoroscopic imaging device (40). A surgical planning instrument (60), such as a pointer or biopsy needle (62), is mounted on an articulated arm (64). As the instrument is inserted into the region of interest, fluoroscopic images are generated and stored in a memory (140). The coordinate systems of the CT scanner, the fluoroscopic device, and the surgical instrument are correlated (102, 104, 112, 120) such that the instrument is displayed on both the CT images (134) and the fluoroscopic images (50), such that cursors move concurrently along the fluoroscopic and CT images, and the like. In a preferred embodiment in which the cursor on the CT image display is at an intersection of transverse, sagittal, and coronal planes, the displayed planes change as the cursor moves coordinating the displayed CT image planes with the position of the cursor on the fluoroscopic image.

Integrated fluoroscopic projection image data, volumetric image data,

A frame (A) of a diagnostic imaging device such as a CT scanner or an MRI device has a bore defining a patient examination region (12). A first x-ray source (B) is mounted to a frame (C) for rotation around the examination region (12). An arc of first radiation detectors (14) detects x-rays which have traversed the examination region. A first image reconstruction processor (18) reconstructs a tomographic image representation from signals generated by the first radiation detectors. A fluoroscopy device (D) is mechanically coupled to the diagnostic scanner for generating and displaying at least substantially real-time fluoroscopic projection image representations on a display monitor (60). A second x-ray source (32) transmits x-rays to an amorphous silicon flat panel radiation detector (36). A second image reconstruction processor (58) reconstructs the fluoroscopic projection image representations from signals generated by the flat panel radiation detector (36). A C-arm (30) supports the second x-ray source (32) and the flat panel radiation detector (36) in a plane offset from a plane of the C-arm. A movable mounting structure (E) is mechanically connected with the gantry (A) and the C-arm (30) to move the C-arm between a stored position and an operating position adjacent the bore.
