摘要： A CT scanner (10) for obtaining a medical diagnostic image of a subject includes a stationary gantry (12), and a rotating gantry (14) rotatably supported on the stationary gantry (12) for rotation about the subject. In a perfusion study 130 time-density curves of voxels of an imaging region are computed. In a low signal identification step (132), all voxels with low signal are identified. In a clustering step (134), low signal voxels are clustered together. In a representative determination step (136) representative time-density curves are computed. In a functional measurement step (138), measurements are calculated from the combined and uncombined time-density values. In an assigning step (140), each low signal voxel is assigned the values determined for its group. In a combining step (142) the results of the low and normal signal voxels are combined to produce a single functional perfusion image.

摘要： An apparatus for measuring parameters preparatory to a stent replacement of an aneurytic blood vessel in a patient (26) includes a computed tomography (CT) scanner (10) that acquires image data (28) corresponding to multiple two-dimensional image slices. A reconstruction processor (32) reconstructs a three-dimensional image representation (34) from the image data (28). A tracking processor (40) produces a tracked vessel (92) including at least a centerline (80) and selected vessel boundaries (86). A user interface (44) displays a rendering (242) of the image representation to an associated user (42), measures selected vascular parameters corresponding to the stent parameters (276), and graphically superimposes the measured parameters on the rendering of the image representation (270, 272).

摘要： A bi-directional communication system (12) is utilized for communications between a technician at an imaging workstation (18), from which imaging protocols can be conducted and at which diagnostic images can be displayed, and one or more hospital medical professionals, located at remote locations. The technician selects and addresses the proper medical professional by a use of an addressing means (50) at workstation (18). The technician selects images (42) to be sent to the selected medical professional. The images and medical professional's address are formatted (46) into wireless transmission format via transmitter/receiver (44) coupled to the workstation (18). A plurality of remote transmitters/receivers (62) receives wireless transmissions at remote locations. Each wireless transmission is examined (68) for a correct address and further converted (70) into an appropriate format for human-readable display. The selected medical professional reviews the images (42) and other information and releases the patient, who awaits the reviewing medical professional's response in the vicinity of the scanner (16).

摘要： A CT scanner (10) for obtaining a medical diagnostic image of a subject includes a stationary gantry (12), and a rotating gantry (14). The detected radiation is reconstructed and divided into sub-portions, which sub-portions are aligned by a registration processor (56). The registered images are stored in a high resolution memory (58) and a maximum artery enhancement value is calculated from the high resolution images. A resolution reducer (82) reduces the resolution of the high resolution images. Time-density curves are found for the voxels of the images, which time-density curves are truncated to eliminate unwanted data, and analyzed to determine characteristic values. A perfusion calculator (106) calculates perfusion by using the maximum artery enhancement value and the characteristic values. A diagnostician can view any one of a low resolution image, a high resolution image, and a perfusion image on a video monitor (112).
