Data accompanying the publication: Three-dimensional view of out-of-plane artifacts in photoacoustic imaging using a laser-integrated linear-transducer-array probe.<br>In this work, we present a 3D reconstruction method using axial transducer array displacement. By axially displacing the transducer array, out-of-plane absorbers can be three-dimensionally visualized at an elevation distance of up to the acquired imaging depth. Additionally, out-of-plane artifacts (OPAs) in the in-plane image are significantly reduced. We experimentally demonstrate the method with phantom and in vivo experiments using an integrated photoacoustic probe. We also compare the method with elevational transducer array displacement and take into account the sensitivity of the transducer array in the 3D reconstruction.

本数据集配套发表论文：《采用集成激光线性换能器阵列探头的光声成像中非平面伪影的三维视图》。本研究提出了一种基于换能器阵列轴向位移的三维重建方法。通过沿轴向移动换能器阵列，可在最大可达成像深度的离轴距离范围内，对非平面吸收体实现三维可视化。此外，平面图像中的非平面伪影（out-of-plane artifacts, OPAs）可得到显著抑制。本研究采用集成式光声探头，通过体模实验与活体实验验证了该方法的有效性。同时，本研究将该方法与换能器阵列仰角位移方法进行对比，并在三维重建过程中充分考虑了换能器阵列的灵敏度特性。
