The electrode structure carries a sensor at a known location on the electrode structure to monitor an operating condition. The systems and methods provide an interface, which generate an idealized image of the electrode structure and an indicator image to represent the monitored operating condition in a spatial position on the idealized image corresponding to the location of the sensor on the electrode structure. The interface displays a view image comprising the idealized image and indicator image. The systems and methods cause the electrode structure to apply energy to heat the tissue region while the view image is displayed on the display screen.

Abstract: The invention provides improvements in reconstructive imaging of the type in which a volume is reconstructed from a series of measured projection images (or other two-dimensional representations) generated by projection of a point x-ray source (or other radiation source), positioned at a distinct focus, through the volume to a plane at which the respective projection image is acquired (“detector plane”). In one aspect, the improvements are with respect to back-projecting a two-dimensional representation lying in the detector plane (representing, for example, a difference between an originally-acquired measured projection image and a subsequently-generated estimate thereof) to generate three-dimensional representation (which can be used, for example, to update an estimate of the volume).

The presentation of a projection image with an unambiguous and immediately understandable depth, information is thereby enabled.

Abstract: The invention concerns a medical imaging station including segmentation means for segmenting at least one imaged object in an image having gray levels, by propagating an edge from at least one initial point positioned in the image on the imaged object. The speed of propagation of the edge depends on said gray levels at each point referred to as a current point and the segmentation means segmenting the image between the points over which the edge passes and the points over which the edge does not pass. According to the invention, the edge propagation means are coupled with means of automatically detecting an emergence of the propagation edge from the imaged object at a current point. Means of locally fixing the speed of propagation at zero at this current point are activated in the event of detection of an emergence of the propagation edge.

Abstract: A computer-implemented method for determining and characterizing, which portions or shapes of a medical image correspond to a shape of interest is provided. A candidate shape is obtained after which a visible surface is computed adjacent to this candidate shape. A visible surface includes one or more portions of the medical image that are visible by the candidate shape. Once the visible surface is determined, parameters of the visible surface are computed. Then the method further includes the step of determining whether the candidate shape corresponds to a shape of interest. The method further includes the step of computing features of the candidate shape and/or classifying the candidate shape. The advantage of the computer-implemented method is that it provides a high detection specificity, i.e. reducing false positives, without sacrificing sensitivity of the detection of a shape of interest.

Abstract: An improved technique is described for acquiring MR image data such as needed for FSE-based Dixon imaging techniques. A gradient-induced echo shift is produced in the pulse sequences by a small gradient applied along the readout axis prior to a readout pulse. When necessary, another small pulse is applied along the readout axis, equal in area and opposite in polarity to the first, to compensate for the shifting effect. Similar pulses are applied for each acquisition window. While data with non-zero phase shifts between water and fat signals are collected as fractional echoes, no increase in echo spacing is necessary with the modified acquisition strategy. Images corresponding to different phase shifts are reconstructed using phase-sensitive partial Fourier reconstruction algorithms whenever necessary. These images are then used to separate different chemical species (such as water and fat) in the object to be imaged.

Abstract: The present invention provides for the use of computer-aided detection (CAD) system output displays for providing accurate representations of areas for subsequent exams. Since the CAD output, unlike the original medical imagery, is not used during the initial reading, the radiologist does not mark it until a final determination is reached regarding subsequent procedures. Additionally, since the CAD output contains versions of the original imagery, the regions indicated by the radiologist are shown in the context of the particular anatomical detail for the given patient. This detail assists the technologist in more efficiently and accurately locating the exact area for subsequent exams.

Abstract: Software, methods and user interfaces for viewing and generating a lung report. In exemplary methods, a first baseline image is analyzed to localize lung nodules. The lung nodule information can be stored and used to relocate the previously localized lung nodules in a second, follow-up imaging scan. The follow-up scan can be analyzed—either manually or automatically—to generate statistics for the lung nodules localized in the follow-up scan. Information derived from the baseline scan can be used to ease the localization of the lung nodules in the follow-up scan. In some exemplary methods, both the baseline scan and follow-up scan are displayed and the nodules are selected for comparison. Typically, the graphical user interface can display a third, composite image that displays the change of size of the nodules.

Abstract: The present invention relates to a method of measuring motion of an object such as a heart by magnetic resonance imaging. A pulse sequence is applied to spatially modulate a region of interest of the object and at least one first spectral peak is acquired from the Fourier domain of the spatially modulated object. The inverse Fourier transform information of the acquired first spectral-peaks is computed and a computed first harmonic phase image is determined from each spectral peak.

The method may be employed to determine the path of motion of a point through a sequence of tag images depicting movement of the heart.
