光声成像是一种新兴的临床前模式,它结合光学和声学机制来可视化目标成像对象中光学吸收的差异。光声成像可能适合脉管系统的可视化,因为红细胞中的血红蛋白是一种重要的吸热剂,因此可以作为一种很好的生物标志物。由于声反射、衍射和散射,当目标软组织靠近骨骼时,光声成像会受到伪影的影响。我们构建了一个具有长骨附近血管化软组织的离体模型,以促进光声图像的评估,并促进未来光声成像中伪影去除的研究。
Photoacoustic imaging is an emerging preclinical modality that uses a combination of optics and acoustics mechanisms to visualize differences in optical absorption in target imaging objects. Photoacoustic imaging is potentially suitable for visualizing vasculature, as the hemoglobin in red blood cells is a prominent heat absorber and therefore serves as a great biomarker. Due to acoustic reflection, diffraction and scattering, photoacoustic imaging is subject to artifacts when the target soft tissue is close to bone. We construct an ex vivo phantom featuring vascularized soft tissue near long bone, to facilitate evaluation of photoacoustic images and to enable future research on artifact removal in photoacoustic imaging.
