Purpose Research in ultrasound imaging is limited in reproducibility by two factors: First, many existing ultrasound pipelines are protected by intellectual property, rendering exchange of code difﬁcult. Second, most pipelines are implemented in special hardware, resulting in limited ﬂexibility of implemented processing steps on such platforms. Methods With SUPRA, we propose an open-source pipeline for fully software-deﬁned ultrasound processing for real-time applications to alleviate these problems. Covering all steps from beamforming to output of B-mode images, SUPRA can help improve the reproducibility of results and make modiﬁcations to the image acquisition mode accessible to the research community. We evaluate the pipeline qualitatively, quantitatively, and regarding its run time. Results The pipeline shows image quality comparable to a clinical system and backed by point spread function measurements a comparable resolution. Including all processing stages of a usual ultrasound pipeline, the run-time analysis shows that it can be executed in 2D and 3D on consumer GPUs in real time. Conclusions Our software ultrasound pipeline opens up the research in image acquisition. Given access to ultrasound data from early stages (raw channel data, radiofrequency data), it simpliﬁes the development in imaging. Furthermore, it tackles the reproducibility of research results, as code can
