摘要

目前,非虚拟神经血管训练可以使用透视引导下的血管造影套件(需要辐射暴露)或使用基于相机的系统直接光学可视化来进行。血管造影方法提供了高保真的可视化和导管控制,但受限于这种专业设备的有限可用性,而基于相机的方法几乎可以在任何地方实施,但在关键的程序方面缺乏可比性。这项工作的目的是开发和评估一种新的基于相机的血管造影训练系统(CBATS),该系统可以生成人工血管造影和路线图,从而结合两种成像技术的优点,同时消除辐射暴露。方法将三种不同的动脉瘤模型整合到一个新的神经介入训练平台中,由神经介入医师通过三种训练成像方式(传统数字减影血管造影[DSA],仅相机可视化和CBATS)对其进行评估,以模拟一般血管内手术。培训课程结束后,进行了一项基于问卷的评估,以比较相机和cbt方法与传统DSA的表现,后者作为金标准。结果90%的评分者认为,我们的cbt训练系统的视觉真实感与真实的血管造影相当,并且比只有摄像头的训练系统有明显的优势。尤其是没有辐射,89.3%的评分者认为这是一个主要优势。综上所述,我们的血管造影训练系统在训练场景的真实感方面可以与真实的血管造影系统相媲美。然而,它的优点是无辐射,几乎可以安装在任何地方。

Angiography-like neurovascular training without radiation utilizing optical cameras and virtual roadmap imaging.

BackgroundAt present, nonvirtual neurovascular training can be performed using either an angiographic suite under fluoroscopic guidance (entailing radiation exposure) or direct optical visualization with a camera-based system. The angiographic approach offers high-fidelity visualization and catheter control but is constrained by the limited availability of such specialized facilities, whereas the camera-based approach can be implemented virtually anywhere yet lacks comparable realism in key procedural aspects. The objective of this work is to develop and evaluate a novel camera-based angiography training system (CBATS) that generates artificial angiograms and roadmaps, thereby combining the advantages of both imaging techniques while eliminating radiation exposure.MethodsThree distinct aneurysm models were integrated into a novel neurointerventional training platform, which was evaluated by neurointerventionalists across three training imaging modalities (conventional digital subtraction angiography [DSA], camera-only visualization, and CBATS) to simulate general endovascular procedures. Following the training sessions, a questionnaire-based evaluation was conducted to compare the performances of the camera-only and CBATS approaches with the conventional DSA, which served as the gold standard.ResultsNinety percent of the raters agree that the visual realism of our CBATS training system is comparable to real angiography and offers a significant advantage over the camera-only variant. The absence of radiation, in particular, was rated as a major advantage by 89.3% of the raters.ConclusionsIn summary, our angiography-like training system is considered comparable to a real angiography system in terms of realism for the training scenarios addressed. However, it offers the advantage of being radiation-free and can be set up in almost any location.
