METHOD FOR COMPUTER-ASSISTED CONFIGURATION OF A MEDICAL IMAGING DEVICE
First Claim
1. A method for computer-assisted configuration of a medical imaging device for examination of a patient, comprising:
- providing training data to a computerized processor that comprise multiple variants of protocols as protocol parameter sets for operation of an imaging device, and patient-specific parameter sets each representing at least one feature of respectively different patients and, in said training data, said protocol parameter sets being respectively associated with said patient-specific parameter sets by means of each protocol parameter set being provided for operating the imaging device for examination of a patient having said at least one feature of the patient-specific parameter set associated therewith;
in said computerized processor, automatically using said training data to generate relations between said multiple protocol parameter sets and said patient-specific parameter sets by implementing a data-driven learning method that produces a plurality of patterns that are stored in a knowledge base; and
via the imaging device, providing a feature of a current patient to be examined with the imaging device and accessing the patterns stored in said knowledge base to determine a protocol, as a selected protocol, from among said multiple variants of protocols, that is appropriate for operating the imaging device to examine said current patient, and making the selected protocol available at an output of the processor in a form for configuring the imaging device to implement the examination of the current patient.

Abstract
In a method for computer-assisted configuration of a medical imaging device for examination of a patient, training data are provided that include multiple variants of protocols in the form of protocol parameter sets for operation of the imaging device. The training data also include patient-specific parameter sets with one or more features of a patient, the patient-specific parameter sets being associated with the respective protocol parameter sets. Based on the training data, relations between the protocol parameter sets and the patient-specific parameter sets are learned with a data-driven leaning method and stored as patterns in a knowledge base. In an application phase, a protocol parameter set suitable for the examination of the patient can be determined with the use of the patterns in the knowledge base, depending on features of a patient that are provided to the imaging device.
