摘要： 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.

摘要： A gantry (A) has a bore defining a first 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. An angiographic device (D) is positioned remote from the gantry along a longitudinal axis (25) for generating and displaying angiographic image representations on a display monitor (46). A second examination region is defined along the longitudinal axis (25) between a second x-ray source (36) and an image intensifier tube (38). A second processor (44) reconstructs the angiographic projection image representations from signals generated by the image intensifier tube (38). A C-arm (30) can be suspended from an overhead track (50) for supporting the second x-ray source (36) and the image intensifier tube (38). A common patient support (24-28) extends along the longitudinal axis between the gantry and the angiographic device for positioning a patient within the first and second examination regions. The patient support includes a slide mechanism (60-64) which permits the patient support to be retracted from the gantry. The processors (18, 44) can be a incorporated into a single controller (E) which fuses or combines an image generated by the angiographic imaging subsystem with an image generated by the tomographic imaging subsystem.

摘要： 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.

摘要： A tomographic scanner includes an imaging device for obtaining images of the anatomy of a patient. A localizer device such as an articulated arm includes a base portion mounted in a fixed relationship to the imaging device and a free end adapted for selective movement into varied positions near a patient body disposed on the imaging device. A guide device such as grid lattice is attached to the free end of the arm. A position transducer associated with the localizer device generates information as to the position of the localizer and hence the position of the guide device in scanner coordinates. The guide device contains a plurality of needle guides. The position of the guide device is displayed in relation to images of the anatomy of the patient. This information is used by the operator to guide the insertion of brachytherapy seeds in a desired pattern and location in relation to the anatomy of the patient.

摘要： A radiation source which generates a radiation cone-beam (14) and a two-dimensional radiation detector are spiralled continuously around and longitudinally relative to an imaging volume. Image data from the two-dimensional display is reconstructed (30.sub.1, 30.sub.2, . . . 30.sub.n) into a volumetric, physiological image stored in a subject memory (32). During an interventional surgical procedure with a surgical instrument (42), the x-ray source is gated to operate intermittently, e.g., at 60.degree. angular intervals, at a reduced radiation intensity by an x-ray tube control (40). The additional data is reconstructed into a three-dimensional image representation of the surgical instrument and stored in an instrument memory (34). An operator image selection processor (60) causes data retrieval circuits (62a, 62b) to retrieve like slices or other image representations from the subject and instrument memories. The retrieved data is combined (64) such that a resultant human-readable display (68) shows the instrument superimposed on the anatomical image. The surgical instrument volumetric image is continuously updated such that the display represents a real time display of the surgical instrument illustrating its advancement through the imaging region.
