  • Patent number: 11041925
    Abstract: A processor controls an MRI system with pulse sequence commands to acquire magnetic resonance data according to a magnetic resonance fingerprinting protocol during multiple pulse repetitions. The pulse sequence commands control the magnetic resonance imaging system to cause gradient induced spin rephasing at least twice during each of the multiple pulse repetitions, and to acquire at least two magnetic resonance signals during each of the multiple pulse repetitions. Each of the at least two magnetic resonance signals is measured during a separate one of the gradient induced spin rephasing. The magnetic resonance data includes the at least two magnetic resonance signals acquired during each of the multiple pulse repetitions. The processor further at least partially calculates a B0-off-resonance map using the magnetic resonance data, and generates at least one magnetic resonance parametric map by comparing the magnetic resonance data with a magnetic resonance fingerprinting dictionary.

  • Publication number: 20200320705
    Abstract: The invention relates to a system for assessing a pulmonary image which allows for an improved assessment with respect to lung nodules detectability. The pulmonary image is smoothed for providing different pulmonary images (20, 21, 22) with different degrees of smoothing, wherein signal values and noise values, which are indicative of the lung vessel detectability and the noise in these images, are determined and used for determining an image quality being indicative of the usability of the pulmonary image to be assessed for detecting lung nodules. Since a pulmonary image shows lung vessels with many different vessel sizes and with many different image values, which cover the respective ranges of potential lung nodules generally very well, the image quality determination based on the different pulmonary images with different degrees of smoothing allows for a reliable assessment of the pulmonary image's usability for detecting lung nodules.

  • Patent number: 10788556
    Abstract: A magnetic resonance imaging system (100) acquires magnetic resonance data (142) from a subject (118) within a measurement zone (108).

  • Publication number: 20200293690
    Abstract: A system (100) and computer-implemented method are provided for data collection for distributed machine learning of a machine learnable model. A privacy policy data (050) is provided defining computer-readable criteria for limiting a selection of medical image data (030) to a subset of the medical image data to obfuscate an identity of the at least one patient. The medical image data is selected based on the computer-readable criteria to obtain privacy policy-compliant training data (060) for transmission to another entity. The system and method enable medical data collection at clinical sites without requiring manual oversight, and enables such selections to be made automatically, e.g., based on a request for medical image data which may be received from outside of the clinical site.
