A controller ascertains a magnetic resonance sequence comprising at least one sub-sequence for detecting at least one substance to be detected in the examination object as a function of the at least one substance to be detected, and ascertains at least one measuring instant for capturing a respective MRT signal to detect the at least one substance to be detected in the examination object as a function of the at least one substance to be detected. The at least one MRT signal is evaluated for fulfillment of a predetermined detection condition, and a presence of the at least one substance to be detected is established when the at least one MRT signal fulfils the predetermined detection condition.

Abstract: A method for identifying emitting species (S1-SN) emitting X- or gamma radiation in a scene, wherein a spectrum of the radiation is supplied as input of a first set of a plurality of convolutional neural networks, each convolutional neural network of the first set being associated with at least one atomic species to be identified and having at least one output indicative of the presence or the absence of the atomic species in the scene. Advantageously, a second set of a plurality of convolutional neural networks makes it possible to determine a signal proportion of each emitting species present in the X- or gamma radiation emanating from the scene.

Abstract: A nozzle arrangement for a spray gun, in particular a paint spray gun, has at least one paint nozzle and an air cap. The paint nozzle has at least one outlet opening for the material to be sprayed and the air cap has at least one central opening which is bounded by at least one wall.
