The invention concerns a method for reproducing spatial impression of existing spaces in multichannel or binaural listening. It consists of following steps/phases: a) Recording of sound or impulse response of a room using multiple microphones, b) Time-and frequency-dependent processing of impulse responses or recorded sound, c) Processing of sound to multichannel loud-speaker setup in order to reproduce spatial properties of sound as they were in recording room, and (alternative to c), d) Processing of impulse response to multichannel loudspeaker setup, and convolution between rendered responses and an arbitrary monophonic sound signal to introduce the spatial properties of the measurement room to the multichannel reproduction of the arbitrary sound signal, and is applied in sound studio technology, audio broadcasting, and in audio reproduction.

A method for generation of a scan path for an x-ray source and/or an x-ray detector of an x-ray system is provided. CT-type imaging on the x-ray system is enabled by traversing the scan path upon simultaneous acquisition of a series of x-ray images.

A viewing axis from the x-ray source to the object and/or the detector is identified for at least one acquisition point on the scan path. A modified scan path is generated by displacement of the at least one acquisition point at least partially along the viewing axis so that the scanning movement upon traversing the modified scan path can be reproduced as in the original scan path.
