High-resolution Power Doppler Using Null Subtraction Imaging

no code implementations9 Jan 2023 Zhengchang Kou, Matthew Lowerison, Qi You, Yike Wang, Pengfei Song, Michael L. Oelze

Up to six-fold resolution improvement was demonstrated by the FWHM estimate and four-fold resolution improvement was demonstrated by the iso-frequency curve from the NSI-based PD microvessel images compared to microvessel images generated by traditional DAS-based beamforming.

Joint localization and classification of breast tumors on ultrasound images using a novel auxiliary attention-based framework

no code implementations11 Oct 2022 Zong Fan, Ping Gong, Shanshan Tang, Christine U. Lee, Xiaohui Zhang, Pengfei Song, Shigao Chen, Hua Li

By use of the attention mechanism, the auxiliary lesion-aware network can optimize multi-scale intermediate feature maps and extract rich semantic information to improve classification and localization performance.
