  • Patent number: 11734599
    Abstract: A method is for adapting method steps for finding a result in a CT-based decision support method to the evaluation of LDCT image datasets. In an embodiment of the method, a plurality of reference image datasets are acquired from a plurality of patients. A reference image dataset features at least one CT image dataset from one of the plurality of patients and an LDCT dataset from the patient. Furthermore, method steps for establishing result data are applied to the different image datasets of the reference image datasets. The result data is compared with one another and the method steps for establishing result data are adapted based upon a result of the comparison to the establishing of result data with reference to an LDCT image dataset. An LDCT-based decision support method is also described. Moreover an adaptation device is described. A system for LDCT-based decision support is further described.

  • Patent number: 11393576
    Abstract: A method for setting a medical imaging protocol includes providing an information data set assigned to a patient. The information data set includes an information about a provisional diagnostic finding regarding the patient. In an embodiment, the method further includes assigning a probability value for a positive finding of the provisional diagnostic finding to the information data set; and automatically setting the medical imaging protocol. The medical imaging protocol is adapted to the provisional diagnostic finding such that an analysis of a result of the medical imaging protocol changes the probability value.

  • Patent number: 11170499
    Abstract: A method is for the automated evaluation of at least one image data record of a patient recorded with a medical image recording device for the preparation of diagnostic findings. In the method, at least one item of input data describing the patient and/or the recording process and/or the examination target is determined after completion of the recording of the image data record. A selection algorithm which evaluates the image data record and the input data is used for determining at least one automated evaluation process to be applied and applicable and at least one image quality measure with regard to the evaluation process is determined by evaluating the image data record. The selected automated evaluation process is only performed for an image quality measure meeting a threshold quality requirement.

  • Patent number: 11074688
    Abstract: For processing a medical image, medical image data representing a medical image of at least a portion of a vertebral column is received. The medical image data is processed to determine a plurality of positions within the image. Each of the plurality of positions corresponds to a position relating to a vertebral bone within the vertebral column. Data representing the plurality of positions is processed to determine a degree of deformity of at least one vertebral bone within the vertebral column.

  • Patent number: 11069439
    Abstract: A method for controlling an evaluation system for medical images of a patient is proposed. Medical images of the patient acquired at different time points are stored in an image database. Upon reception of a user command associated with a time-dependent evaluation command including at least one evaluation parameter describing an evaluation to be performed and identification information describing the patient, medical images of the patient fulfilling a relevancy criterion depending on the evaluation parameter and acquired at different time points are retrieved from the image database. The retrieved images are registered to each other in at least one registration process. Finally, a composite evaluation image data set including a time series of evaluation images is derived from the registered retrieved images and output to the user.

  • Patent number: 10751943
    Abstract: In personalized object creation, for implants, medical imaging is used to derive a model personalized to a patient. The model may be of a dynamic structure, such as part of the cardiovascular system, and is used to print the implant itself. The model may be used to print a mold to create the implant, a scaffold on which to grow tissue, and/or tissue itself. In another or additional approach, the medical imaging information is used to determine tissue properties. Differences in a material property of the anatomy is mapped to different materials used by a multi-material 3D printer, resulting in a printed object reflecting the size, shape, and/or other material property of the anatomy of the patient.
