Abstract: The present invention relates to a method for processing at least a pre-contrast image depicting a body part prior to an injection of contrast agent, the method being characterized in that it comprises the implementation, by a data processor (11b) of a second server (1b), of steps of: (a) Obtaining said pre-contrast image; (b) Determining candidate value(s) of at least one injection parameter of said injection of contrast agent by application of a prediction model to said pre-contrast image, such that a theoretical contrast image depicting said body part during injection of contrast agent in accordance with the determined candidate value(s) of said injection parameter(s) is expected to present a target quality level.

Abstract: A method for time-resolved tomosynthesis imaging for a moving object includes moving an imaging device having an x-ray source and an x-ray detector around the moving object and recording raw image data for a temporal series of tomosynthesis images. The method also includes reconstructing the temporal series of tomosynthesis images from the raw image data. While the imaging device is being moved, a motion speed of the imaging device is matched to a speed, at which the moving object is moving.

Abstract: A method for functional visualization and localization of an arteriovenous malformation is proposed. A patient is scanned over a predetermined projection angle range during a contrast agent uptake time. The examination region is reconstructed using the projections over the entire projection angle range. The arteriovenous malformation is localized. The multiplicity of the projections is subdivided into at least three partial projection datasets each belonging to different consecutive time windows of the total duration of the scan. A time series having tomosynthesis image datasets is generated by the partial projection datasets. An arterial and/or venous assignment of the vessels flooded with contrast agent takes place based on the time series of tomosynthesis image datasets.

Abstract: An embodiment in the MRI-CEST field is proposed for analyzing a body-part, which includes a CEST agent providing a magnetization transfer with a bulk substrate of the body-part. A corresponding diagnostic system includes input means for providing an input map including a plurality of input elements each one for a corresponding location of the body-part; each input element is indicative of a spectrum of a magnetic response of the location, which spectrum includes the magnetic response at an agent frequency of resonance of the contrast agent (with the agent frequency that is at an agent offset of frequency from a bulk frequency of resonance of the bulk substance), and at a reference frequency at the opposite of the agent offset from the bulk frequency.

Abstract: A method is disclosed for operating a radiation therapy system. The radiation therapy system includes a magnetic resonance apparatus. In an embodiment of the method, an irradiation plan is received for a patient. While the patient is arranged in the radiation therapy system and a hyperpolarized contrast agent has been administered, magnetic resonance data of the patient is acquired. In the magnetic resonance data, molecular irradiation target areas are determined on the basis of the hyperpolarized contrast agent and the received irradiation plan is corrected as a function of the molecular irradiation target areas determined in the magnetic resonance data. A molecular irradiation target area relates to an area of the patient with a molecular property.
