This invention discloses a 4D-CT-based method for visualizing lung perfusion, belonging to the field of intelligent medical technology. The method includes: acquiring 4D-CT scan data of a patient's lungs; acquiring the patient's cardiac waveform based on the scan data; acquiring the patient's lung waveform based on the scan data; performing correlation analysis on the cardiac and lung waveforms to obtain a correlation coefficient; and outputting a time-series color image of lung perfusion based on the correlation coefficient. This invention can directly utilize conventional breath-hold 4D-CT volumetric data, intuitively presenting the propagation characteristics of lung perfusion without the need for additional hardware or examination procedures. This method does not require the injection of contrast agents, completely avoiding the risks associated with contrast agents, and has better safety and repeatability. Furthermore, the overall calculation process is highly automated and has a short detection time, improving examination and evaluation efficiency to a certain extent.

The application discloses a method for creating a DH line of eggplant by using anther culture and application thereof, and relates to the technical field of plant breeding. The application establishes a morphological index of a flower bud based on a calyx lobe separation state, replaces a time-consuming microscope examination procedure, and optimizes a combination of heat treatment and low-temperature pretreatment, so that the embryoid induction rate is significantly improved. Finally, through strict ploidy identification and self-pollination purification, a DH line with consistent traits and stable heredity can be obtained, an efficient pure line source is provided for eggplant hybrid breeding, and efficient conversion from a heterozygous genotype plant to a homozygous DH line is realized.

The disclosure relates to a computer-implemented method for operating a MRI facility. The MRI facility may include a user interface for configuring a series of measurement protocols to be implemented in an examination procedure on an object. The protocols are checked in checking procedure(s) for compliance with safety requirement(s) relating to the object and / or MRI facility. The protocols are executed only on compliance with each of the safety requirements. On receipt of a check readiness signal, which indicates a user input has been made specifying that a user has completed configuring a selected measurement protocol, the selected measurement protocol is labeled as ready for checking, so that at least one implementable checking procedure can already be implemented and / or is implemented before it is the turn of the measurement protocol. The implementation can be even while a user is configuring at least one further measurement protocol.

This invention belongs to the field of speech recognition technology. It discloses a system and method for generating gastrointestinal endoscopy reports based on medical speech recognition. The system includes a speech acquisition and processing module for acquiring real-time spoken speech from doctors during gastrointestinal endoscopy, performing adaptive noise reduction and mask occlusion compensation on the spoken speech, and outputting a speech segment sequence; a speech activity detection module for receiving the speech segment sequence, calculating the prior probability of speech activity based on the transition relationships of different operational states in the endoscopy procedure, and performing speech activity detection on the speech segment sequence based on the prior probability of speech activity to filter out speech event sequences consistent with the examination procedure; and a speech-image alignment module for transcribing the speech event sequences into medical speech, acquiring endoscopic images at corresponding times, and completing the ambiguous spoken content in the speech event sequence based on the endoscopic images to generate speech description data. This improves the automation level of examination recording.

The invention relates to a computer-implemented method for operating an imaging X-ray apparatus for providing a virtual patient model for a patient examination procedure, determining a virtual patient model on the basis of patient information; determining a model position of the patient model in a coordinate system of the X-ray apparatus; and positioning the patient model in accordance with the model position, for determining the patient model position, at least one X-ray image recorded in a current patient position in the X-ray apparatus during the examination procedure and present in the coordinate system of the X-ray apparatus is input as input data into a trained position determination function, the output data of the position determination function specifying a correspondence between at least one salient point of the patient model and at least one salient point of the X-ray image, wherein the model position is determined from the output data. The invention also relates to an X-ray apparatus, a computer program product and an electronically readable data carrier.

A method for operating an X-ray device includes ascertaining a patient model of a patient that describes a surface of the patient, based on patient information. A model position is determined for the patient model in a coordinate system of the X-ray device, in which radiation distribution during an X-ray image acquisition of the examination procedure is also known. The patient model is positioned in accordance with the model position. An X-ray image of the examination procedure, which is acquired for a current patient position of the patient in the X-ray device and exists in the coordinate system of the X-ray device, is supplied as input data to a trained position determination function. Output data from the trained position determination function describes a mapping of a distinguished point of the patient model to a distinguished point of the X-ray image. The model position is determined from the output data.

The invention relates to a computer-implemented method for operating a magnetic resonance apparatus for imaging, comprising an operating device which provides a user interface for setting a sequence of measurement protocols to be carried out on an examination object during an examination process, wherein the measurement protocol is examined in at least one examination process in regard to whether at least one safety requirement relating to the examination object and / or the magnetic resonance device is followed, and is executed only if each of the at least one safety requirement is met, a measurement protocol is marked as check-ready, the check-ready signal displaying an ongoing user input describing an end of the user setting the selected measurement protocol for the check process, such that at least one of the at least one check process is executable. Before rounds to a measurement protocol for execution according to a sequence in the inspection process, the process is executable and / or executed.
