Abstract: Apparatus (10) for making biomagnetic measurements includes a biomagnetometer (18) for measuring magnetic fields produced by the body and an electromagnetic location measurement and recording system (20 and 30) for automatically determining the location of the portion of the body (12) from which the magnetic signals are being gathered. The electromagnetic location recording system permits establishing a real time body frame of reference with respect to the biomagnetometer, so that biomagnetic signals can be correlated directly with body location and structure. The electromagnetic location recording system may be operated continuously at radiation wavelengths which do not interfere with the taking of data, or intermittently with the taking of biomagnetic data, to avoid interference with the measured values of the biomagnetic data. The elements of the electromagnetic location recording system have substantially no residual magnetism when the location recording system is not operating, as the biomagnetic signals are typically so small that even normal residual magnetism might be erroneously recorded as a biomagnetic signal.

Abstract: An NMR imaging method which collects only those data that are used for re-constituting the image in order to reduce the scanning time. A circular region with a point at which space frequency is zero as a center is determined on a two-dimensional Fourier plane that corresponds to the region for re-constituting the image. Spin echo signals are measured by an ordinary Fourier method for a local region in the circular region where the measured data has a length greater than a predetermined length in the reading direction. For other regions in the circular region, a plurality of spin echo signals are measured while successively reducing the time for applying a magnetic reading gradient field per excitation of each time and while additionally encoding the phase.

Abstract: This invention is an invasive probe apparatus including flexible elongate probe (20) having a distal portion adjacent to a distal end (22) thereof for insertion into the body of a subject, which portion assumes a predetermined curve form when a force is applied thereto. First and second sensors (28, 30) are fixed to the distal portion of the probe (20) in known positions relative to the distal end (22), which sensors generate signals responsive to bending of the probe. Signal processing circuitry (36) receives the bend responsive signals and processes them to find position and orientation coordinates of at least the first sensor (28), and to determine the locations of a plurality of points along the length of the distal portion of the probe.

Abstract: This invention describes a method for aligning radiation therapy beams with a treatment target of a patient. Diagnostic computer tomography scanning is used to map the treatment target in the patient's anatomy and to aid physicians in deciding where to aim the radiation therapy beams. Digitally reconstructed radiographs are generated from an intermediate 3-D image produced from the CT scans. These DRRs are compared with x-ray images taken of the treatment target's position taken at the time of treatment. A transformation equation is used to compare the DRRs and the x-ray images. A minimization equation is used to determine the similarity between the two sets of images. If the difference between the two sets fall below a determined minimum value, then the position of the treatment target is deemed correct and the radiation therapy begins. If the difference does not fall below the determined minimum value, then either the radiation beams or the treatment target is adjusted and the process is repeated. This procedure may be used many times in the course of a single treatment session, depending on the movement of the patient.

Abstract: Audio information is spoken into a microphone and saved in digitized form in an electronic file (40). The digitized information is converted into a format which is usable within a particular MRI system (42). Thereafter, an electronically store pulse sequence, useable within the selected MRI system, is selected (46) and edited (48) to incorporate the converted digitized verbal information (50) and appropriate header information (44). When the edited pulse sequence is operated by the MRI system, audio information is projected which can be heard by the human ear using the elements of an existing MRI system.
