摘要： A medical data generating apparatus includes a data processing unit, a work-status data generation unit, a display unit and a work-status restoration unit. The data processing unit acquires medical data from a database to perform data processing. The work-status data generation unit generates work-status data as a data record of medical data. The work-status data indicates a work status of the data processing. The display unit acquires medical data including at least one piece of work-status data from the database to list the acquired pieces of the medical data on a display device together with identification information of the acquired piece of the work-status data. The work-status restoration unit restores a work status of a data processing corresponding to a selected piece of work-status data based on the selected piece of the work-status data.

摘要： The medical image processing device comprises a detection part, a storage part, an image generation part, and a display-control part. The detection part detects positions and directions of an endoscope. The storage part stores medical image data showing tubular tissues generated by a medical imaging device different from the endoscope. The image generation part generates virtual endoscopic image data showing the internal portion of the tubular tissues based on the medical image data having a position that is a predetermined distance away from the position of the endoscope as a viewpoint. The display-control part receives endoscopic image data showing the internal portion of the tubular tissues generated by the endoscope and displays an endoscopic image based on the endoscopic image data and a virtual endoscopic image based on the virtual endoscopic image data on a display part.

摘要： A method to null a phase relevant to a high-order moment and minimize an echo time TE when a GMN or flow-encoding gradient pulse is employed. The first to n-th trapezoidal-wave pulses of which polarities are alternately mutually opposite are applied as a gradient pulse. The amplitude g and pulse duration t of the first trapezoidal-wave pulse, and the slope k of pulses of the first trapezoidal-wave pulse are given as initial values. Parameters including a plurality of known pulse duration coefficients b.sub.1, b.sub.2, etc. determining pulse durations b.sub.1.t, b.sub.2.t, etc. of the first to n-th trapezoidal-wave pulses, and unknown magnetic field gradient strength coefficients a.sub.1, a.sub.2, etc. determining amplitudes a.sub.1.g, a.sub.2.g, etc. of the second and subsequent trapezoidal-wave pulses are given. Expressions concerning phases of nuclear spins producing an MR signal are solved analytically so that the values of terms of phases relevant to moments in the expressions can be controlled to be desired values or nulled according to the purpose of use of the gradient pulse. A combination of the coefficients b.sub.1, b.sub.2, etc. satisfying the results of the analysis, in which the coefficient b.sub.3 for a pulse interval defining the pulse spacing of the n-th trapezoidal-wave pulse has the smallest value, is selected.
