Abstract

BACKGROUND

This pilot study was performed to evaluate whether virtual reality is applicable for three-dimensional echocardiography and if three-dimensional echocardiographic 'holograms' have the potential to become a clinically useful tool.

METHODS

Three-dimensional echocardiographic data sets from 2 normal subjects and from 4 patients with a mitral valve pathological condition were included in the study. The three-dimensional data sets were acquired with the Philips Sonos 7500 echo-system and transferred to the BARCO (Barco N.V., Kortrijk, Belgium) I-space. Ten independent observers assessed the 6 three-dimensional data sets with and without mitral valve pathology. After 10 minutes' instruction in the I-Space, all of the observers could use the virtual pointer that is necessary to create cut planes in the hologram.

RESULTS

The 10 independent observers correctly assessed the normal and pathological mitral valve in the holograms (analysis time approximately 10 minutes).

CONCLUSION

this report shows that dynamic holographic imaging of three-dimensional echocardiographic data is feasible. However, the applicability and use-fullness of this technology in clinical practice is still limited.

摘要

背景

本初步研究旨在评估虚拟现实技术是否适用于三维超声心动图，以及三维超声心动图“全息图”是否有潜力成为一种临床实用工具。

方法

本研究纳入了2名正常受试者和4名患有二尖瓣病变患者的三维超声心动图数据集。三维数据集通过飞利浦Sonos 7500超声系统采集，并传输至BARCO（比利时科特赖克Barco N.V.公司）I-space。10名独立观察者对6个有无二尖瓣病变的三维数据集进行评估。在I-Space接受10分钟的指导后，所有观察者均可使用在全息图中创建切面所需的虚拟指针。

结果

10名独立观察者正确评估了全息图中的正常和病变二尖瓣（分析时间约10分钟）。

结论

本报告表明，三维超声心动图数据的动态全息成像可行。然而，该技术在临床实践中的适用性和实用性仍然有限。
