Ultrasound and photoacoustic beamforming
WebOvarian cancer is the fifth most common cause of death due to cancer, and it is the deadliest of all gynecological cancers. Diagnosing ovarian cancer via conventional photoacoustic delay-and-sum beamforming (DAS) presents several challenges, such as poor image resolution and low lesion to background tissue contrast. To address these … Web5 Mar 2024 · Delay and Sum (DAS) is one of the most prevalent and common beamforming algorithms used in ultrasound and photoacoustic image (PAI) reconstruction. This beamforming algorithm is mostly used due to its simple implementation and real time capability. However, it has several drawbacks such as high level side lobes, low image …
