When Pulling Fails: Understanding and Alleviating SDF Collapse in Sparse Freehand Ultrasound Reconstruction

Jiuan Chen, Song Lai, zhao mingyang, Gaofeng Meng

IJCAI 2026

Despite being a cost-effective modality for volumetric imaging, freehand three-dimensional (3D) ultrasound produces inherently sparse data due to the significant elevational gaps left by tracked 2D sweeps. This sparsity poses a unique challenge for Implicit Neural Representations (INRs). While succe

Fully Robotized 3D Ultrasound Image Acquisition for Artery

Mingcong Chen, Yuanrui Huang, Jian Chen, Tongxi Zhou, Jiuan Chen, Hongbin Liu

ICRA 2023poster

Current imaging of the artery relies primarily on computed tomography angiography (CTA), which requires contrast injections and exposure to radiation. In this paper, we present a method for fully autonomous artery 3D image acquisition using a linear ultrasound (US) probe and a 6 DoFs robot arm with…
