“…Papers on time domain modelling of ultrasound transmission [15,21,19] use spatial impulse response techniques, whereas papers working in Fourier domains deal with the problem directly in the frequency domain by considering the spectrum of the signal instead of the waveform in time, with the so-called Fresnel approximation [7,23,34], from a compressed sensing viewpoint [5], or with the angular spectrum method [10,30,33].…”

Medical ultrasound imaging is the most widespread real-time noninvasive imaging system and its formulation comprises signal transmission, signal reception, and image formation. Ultrasound signal transmission modelling has been formalized over the years through different approaches by exploiting the physics of the associated wave problem. This work proposes a novel computational framework for modelling the ultrasound signal transmission step in the time-frequency domain for a linear-array probe. More specifically, from the impulse response theory defined in the time domain, we derived a parametric model in the corresponding frequency domain, with appropriate approximations for the narrowband case. To validate the model, we implemented a numerical simulator and tested it with synthetic data. Numerical experiments demonstrate that the proposed model is computationally feasible, efficient, and compatible with realistic measurements and existing state-of-the-art simulators. The formulated model can be employed for analyzing how the involved parameters affect the generated beam pattern, and ultimately for optimizing measurement settings in an automatic and systematic way.
