通过血管造影术获得的脑血管图像被神经外科医生用于诊断、手术计划和术中指导。然而，血管和分叉的复杂分支使得理解这些图像的空间三维布局的任务具有挑战性。在本文中，我们提出了不同的知觉线索（雾，pseudo-chromadepth，动力学深度，描绘边缘）的效果的实证研究，单独和组合的脑血管容积的深度知觉，并比较这些线索的立体视觉。两个实验与新手和一个实验与专家进行。对初学者的实验结果表明，伪色深和雾线索比立体视觉线索更强。此外，除了立体视觉线索的其他线索并没有改善脑血管容积的相对深度知觉。与新手相比，专家在边缘线索上的表现也很好。就新手和专家受试者而言，伪色度深度和雾允许最佳的相对深度感知。通过使用这些线索来改善脑血管系统的深度感知，我们可以改善诊断，手术计划和术中指导。
Cerebral vascular images obtained through angiography are used by neurosurgeons for diagnosis, surgical planning, and intraoperative guidance. The intricate branching of the vessels and furcations, however, make the task of understanding the spatial three-dimensional layout of these images challenging. In this paper, we present empirical studies on the effect of different perceptual cues (fog, pseudo-chromadepth, kinetic depth, and depicting edges) both individually and in combination on the depth perception of cerebral vascular volumes and compare these to the cue of stereopsis. Two experiments with novices and one experiment with experts were performed. The results with novices showed that the pseudo-chromadepth and fog cues were stronger cues than that of stereopsis. Furthermore, the addition of the stereopsis cue to the other cues did not improve relative depth perception in cerebral vascular volumes. In contrast to novices, the experts also performed well with the edge cue. In terms of both novice and expert subjects, pseudo-chromadepth and fog allow for the best relative depth perception. By using such cues to improve depth perception of cerebral vasculature, we may improve diagnosis, surgical planning, and intraoperative guidance.
