A method of scanning an organ structure of a patient using magnetic resonance imaging, includes scanning, in a first scanning process, the patient to obtain first image data indicative of at least the organ structure of the patient. The method further includes determining, based on the first image data, one or more parameters obtain second image data indicative of at least the organ structure of the patient. The first scanning process includes a first quality of imaging scan, the second scanning process includes a second quality of imaging scan, and the first quality of imaging scan is higher than the second quality of imaging scan.

A method for operating a magnetic resonance device is provided. The magnetic resonance device includes a component that has an operating limit in relation to a state parameter. The component uses a protocol to record magnetic resonance data. The protocol includes a magnetic resonance sequence and is described by protocol parameters. A protocol parameter set that, in relation to a protocol section, allows the protocol section to be repeated as often as desired without exceeding the operating limit is provided or determined. The method includes receiving a boost parameter from a user interface. At least for the protocol section, adaptation parameters are determined at least partially automatically based on the boost parameter, such that the desired number of repetitions described by the boost parameter is established while complying with the operating limit. Magnetic resonance data is recorded with the protocol using the determined adaptation parameters.

For autonomous MR scanning for a given medical test, a simplified MR scanner may be used without or will little input or control by a technologist (e.g., by a physician, radiologist, or person trained in MR scanner operation). The MR scanner autonomously positions, scans, checks quality, analyzes, and/or outputs an answer to a diagnostic question with or without an MR image. Scan analysis, based on artificial intelligence, allows for on-going or on-the-fly alteration of the scanning configuration to acquire the data desired to answer the diagnostic question. By using a simplified MR scanner, both position of the patient relative to the MR scanner and localization of the scan by the MR scanner are jointly solved. Sensors may sense a patient in a scan position where the reduced radio frequency requirements allow for a more open bore.
