A computer-implemented medical method of determining a patient-specific setting of at least one imaging parameter of an imaging device, wherein the method comprises the following steps: - patient data is acquired, describing information relating to a patient and having impact on the setting of at least one imaging parameter of the imaging device, the information relating to the patient including at least one of: - the patient's age; - the patient's gender; - the patient's weight; - the patient's height; - a type of disease of the patient and/or a type of an associated, particularly scheduled treatment procedure; - a position, size and/or shape of a region to be imaged; - object data is acquired, describing the spatial position of an object of interest within the field of view of the imaging device and associated with the anatomy of the patient, the object of interest being a trajectory for a medical implant, device or instrument; - imaging parameter data is determined based on the patient data and the object data, describing a patient-specific setting of the at least one imaging parameter of the imaging device, the at least one imaging parameter of the imaging device being selected from the list comprising: - a position of the isocenter of the imaging device with respect to the patient's anatomy; - a position, size and/or shape of the imaging region with respect to the patient's anatomy, with respect to objects coupled the patient's anatomy and/or with respect to the imaging device; - a position of a scan trajectory with respect to the patient's anatomy and/or with respect to objects coupled the patient's anatomy; - a position of the imaging device with respect to the patient's anatomy and/or with respect to objects coupled the patient's anatomy; - a selection of a reconstruction kernel and algorithm; - a subtraction angiography modality; - a dual-energy imaging modality; - a number of acquired projections; - a modality and/or setting for post-processing at least one image obtained with the imaging device. - patient data is acquired, describing information relating to a patient and having impact on the setting of at least one imaging parameter of the imaging device, the information relating to the patient including at least one of: - the patient's age; - the patient's gender; - the patient's weight; - the patient's height; - a type of disease of the patient and/or a type of an associated, particularly scheduled treatment procedure; - a position, size and/or shape of a region to be imaged; - the patient's age; - the patient's gender; - the patient's weight; - the patient's height; - a type of disease of the patient and/or a type of an associated, particularly scheduled treatment procedure; - a position, size and/or shape of a region to be imaged; - object data is acquired, describing the spatial position of an object of interest within the field of view of the imaging device and associated with the anatomy of the patient, the object of interest being a trajectory for a medical implant, device or instrument; - imaging parameter data is determined based on the patient data and the object data, describing a patient-specific setting of the at least one imaging parameter of the imaging device, the at least one imaging parameter of the imaging device being selected from the list comprising: - a position of the isocenter of the imaging device with respect to the patient's anatomy; - a position, size and/or shape of the imaging region with respect to the patient's anatomy, with respect to objects coupled the patient's anatomy and/or with respect to the imaging device; - a position of a scan trajectory with respect to the patient's anatomy and/or with respect to objects coupled the patient's anatomy; - a position of the imaging device with respect to the patient's anatomy and/or with respect to objects coupled the patient's anatomy; - a selection of a reconstruction kernel and algorithm; - a subtraction angiography modality; - a dual-energy imaging modality; - a number of acquired projections; - a modality and/or setting for post-processing at least one image obtained with the imaging device. - a position of the isocenter of the imaging device with respect to the patient's anatomy; - a position, size and/or shape of the imaging region with respect to the patient's anatomy, with respect to objects coupled the patient's anatomy and/or with respect to the imaging device; - a position of a scan trajectory with respect to the patient's anatomy and/or with respect to objects coupled the patient's anatomy; - a position of the imaging device with respect to the patient's anatomy and/or with respect to objects coupled the patient's anatomy; - a selection of a reconstruction kernel and algorithm; - a subtraction angiography modality; - a dual-energy imaging modality; - a number of acquired projections; - a modality and/or setting for post-processing at least one image obtained with the imaging device.
