A stereotactic device for use with an imager such as a magnetic resonance imager is disclosed, which permits an imaging scan to be taken with reference to a personal coordinate system (or PCS) that is independent of a machine coordinate system (or MCS). Methods using the device to obtain imaging scans are described such that the imaging scans are superimposable even if taken at different time periods using the same or a different imager. The device comprises a frame that can be reproducibly positioned on a subject and which is equipped with non-invasive affixing means and localizing means that provide the PCS. The device and methods of the invention are particularly well suited for routine initial or follow-up examinations, pre-surgical planning and post-surgical evaluation. Markers on a stereotactic device can be tracked during an MRI scan to compensate for patient motion during the scan.

High resolution B-mode ultrasound images of the common carotid artery are obtained with an ultrasound transducer using a standardized methodology. Subjects are supine with the head counter-rotated 45 degrees using a head pillow. The jugular vein and carotid artery are located and positioned in a vertical stacked orientation. The transducer is rotated 90 degrees around the centerline of the transverse image of the stacked structure to obtain a longitudinal image while maintaining the vessels in a stacked position. A computerized methodology assists operators to accurately replicate images obtained over several spaced-apart examinations. The methodology utilizes a split-screen display in which the arterial ultrasound image from an earlier examination is displayed on one side of the screen while a real-time "live" ultrasound image from a current examination is displayed next to the earlier image on the opposite side of the screen. By viewing both images, whether simultaneously or alternately, while manually adjusting the ultrasound transducer, an operator is able to bring into view the real-time image that best matches a selected image from the earlier ultrasound examination. Utilizing this methodology, measurement of vascular dimensions such as carotid arterial IMT and diameter, the coefficient of variation is substantially reduced to values approximating from about 1.0% to about 1.25%. All images contain anatomical landmarks for reproducing probe angulation, including visualization of the carotid bulb, stacking of the jugular vein above the carotid artery, and initial instrumentation settings, used at a baseline measurement are maintained during all follow-up examinations.

A CT- or MRT-assisted image acquisition, image archiving and image rendering system allows generation, storage, post-processing, retrieval and graphical visualization of computed or magnetic resonance tomography image data that, for example, can be used in the clinical field in the framework of radiological slice image diagnostics as well as in the framework of interventional radiology. Moreover, a method implemented by this system allows reproduction of patient-specific examination parameters of an initial examination implemented by means of computed or magnetic resonance tomography imaging in the framework of CT or MRT follow-up examinations (“follow-ups”), for example in a post-operative tumor examination implemented under slice image monitoring in connection with a histological tissue sample extraction (biopsy) implemented under local anesthesia or a minimally-invasive intervention implemented for tumor treatment. Acquisition, measurement, 2D and / or 3D reconstruction parameters from a radiological initial examination of the patient conducted by means of CT, PET-CT or MRT as well as position data to establish the position adopted by this patient on the examination table of a computed tomography or magnetic resonance tomography apparatus are electronically documented, retrievably and persistently stored, and are automatically reused given subsequent CT-, PET-CT- or MRT-based monitoring examinations, or CT-controlled or MRT-controlled interventional or operative procedures.
