Specific embodiments of the invention are directed to improved phacoemulsification procedures involving the use of processed non-visual three-dimensional data (i.e. diagnostic scan data) to provide a surgeon with additional guidance (i.e. more than that generally obtained from visual observation of the working area) concerning the distance separating a working end of a phacoemulsification instrument and the posterior portion of the capsule of the eye during surgical procedures involving the removal of the crystalline lens of an eye (e.g. a cataract removal procedure). Such separation (i.e. distance or gap) information may be used to aid the surgeon in cutting or scoring the lens to a desired depth while minimizing the risk of penetrating the posterior portion of the capsule with the working end of the instrument. Some embodiments provide for the visual and/or auditory conveyance of distance information to the surgeon wherein visual information may be conveyed by overlaying it with real visual images of actual surface features viewed by the surgeon. Additional embodiments provide for overlaying visual representations of selected three-dimensional structure information (e.g. depths of troughs cut into the lens) with the real surface feature images viewed by the surgeon.

An advantage of this new automotive collision repair technology is that it enables proper and proven repairs, which in turns increases operation safety of repaired vehicle and people safety.

A method and system for automated magnetic resonance (MR) scan prescription is disclosed. A 3D MR scout image is obtained by an initial MR scan. The location of an optic nerve in the scout image is determined by registering a template image to the scout image using a hierarchical series of rigid registrations. The hierarchical series of rigid registrations utilizes a coarse to fine scheme to register regions in the template image to the scout image, starting with the whole template image and finishing with the optic nerve. A diagnostic MR scan is then aligned based on the location of the optic nerve in the scout image, and the diagnostic scan is performed resulting in a high quality diagnostic 3D MR image.

A method and system for automatic MR brain scan planning is disclosed. The method utilizes a set of 2D orthogonal localizer images to determine scanning planes for 3D diagnostic MR scans. A location of the mid-sagittal plane (MSP) is detected in each of a transversal localizer image and a coronal localizer image. A sagittal scanning plane is determined based on the location of the MSP in the transversal and coronal localizer images. A diagnostic sagittal MR scan is then acquired based on the sagittal scanning plane. The corpus callosum CC is segmented in a sagittal MR image slice resulting from the diagnostic sagittal MR scan. A transversal scanning plane can be determined based on a location of the CC in the sagittal MR image slice and the location of the MSP in the coronal localizer image, and a coronal scanning plane can be determined based on the location of the CC in the sagittal MR image slice and the location of the MSP in the transversal localizer image.

A method and system for dose-optimized acquisition of a computed tomography (CT) scan of a target organ is disclosed. A localizer spiral CT scan is started at a beginning of a confidence range before a target organ. Real-time localizer scan images are automatically analyzed to predict a beginning location of the target organ based on the real-time localizer scan images. A diagnostic spiral CT scan is automatically started at the predicted beginning location of the target organ. Real-time diagnostic scan images are automatically analyzed to predict an end location of the target organ where full coverage of the target organ will be reached. The diagnostic spiral CT scan is automatically stopped in response to reaching the predicted end location of the target organ. A 3D profile can be acquired using a 3D camera and used to determine the confidence range before the target organ.

A diagnostic scanning apparatus includes a hollow rotor sized to receive a patient. First and second flanges are connected to and extend radially outward from the rotor in a spaced-apart relationship, each of the first and second flanges including, at least in part, a magnetically-permeable material. A radiation source is affixed to the first flange and/or the rotor. A first axial actuator generates a variable magnetic field, is fixedly disposed adjacent to the first flange and can magnetically pull the first flange in a first axial direction of the rotor. A second axial actuator generates a variable magnetic field, is fixedly disposed adjacent to the second flange and can magnetically pull the second flange in a second axial direction of the rotor that is opposite of the first axial direction. The first and second axial actuators are both at least substantially disposed between the first and second flanges.

In a magnetic resonance (MR) imaging method and apparatus, multiple diagnostic scans are obtained of an examination subject during an imaging session. An initial reference scan of the subject is obtained at the beginning of the session and, as the session proceeds, an automatic determination is made before each diagnostic scan is obtained as to whether the immediately preceding reference scan is still valid, primarily be checking whether an amount of patient movement has occurred that renders the immediately preceding reference scan invalid. Either a new reference scan is obtained before the next diagnostic scan, or, if still valid, the immediately preceding reference scan is used for the next diagnostic scan.

In a parallel or SENSE imaging technique in an MRI system (40), a calibration scan is conducted to generate a calibration image (86) indicative of sensitivity profiles of parallel imaging coils (76a, . . . ,76n) also in the regions where the magnetic field is distorted. This is accomplished by using a phase refocusing imaging protocol such as a spin echo technique, or by using a gradient echo technique where the echo time is very short. In addition, the phase encode direction of the calibration scan and a diagnostic imaging scan shall be matched. A diagnostic imaging scan is conducted using a diagnostic scan protocol to generate a diagnostic image representation from each parallel imaging coil. A SENSE processor (90) reconstructs a final diagnostic image (92) from the diagnostic image representations and the coil sensitivity profiles.

The present invention concerns a method and an apparatus for phase-calibrating an MRI pulse sequence which is used to calculate a linear phase and a constant phase to perform phase calibration on the scanned data, wherein a corresponding pre-scan without a phase encoding gradient is performed before a diagnostic scan. A reference echo is selected from the echoes obtained in the pre-scan. On the basis of the reference echo the constant phase is calculated to be used in performing the phase calibration in the scan. The constant phase that is obtained is correct and not affected by phase jumping. A further image reconstruction performed on the phase-calibrated data produces clear and artifact-free images.
