阴道壁、结缔组织和肌肉弹性的变化被认为是盆腔器官脱垂的重要因素，在美国，这种疾病在一生中至少影响到50%的女性。对于骨盆支持组织的生物力学特性，它提出了两个突出的问题：组织弹性如何影响盆腔器官脱垂的发展，以及如何通过重建手术保持功能弹性。我们设计了一台阴道触觉成像仪(VTI)的原型，用于可视化和评估盆底组织的弹性特性。在这篇文章中，我们分析了触觉成像在评估重建手术结果以及描述正常和盆腔器官脱垂情况方面的适用性。一项对13名患者进行的初步临床研究表明，由于重建骨盆手术后植入网状移植物，VTI使阴道壁的硬度增加，VTI具有表征和检测脱垂的潜力。
Changes in the elasticity of the vaginal walls, connective support tissues, and muscles are thought to be significant factors in the development of pelvic organ prolapse, a highly prevalent condition affecting at least 50% of women in the United States during their lifetimes. It creates two predominant concerns specific to the biomechanical properties of pelvic support tissues: how does tissue elasticity affect the development of pelvic organ prolapse and how can functional elasticity be maintained through reconstructive surgery. We designed a prototype of vaginal tactile imager (VTI) for visualization and assessment of elastic properties of pelvic floor tissues. In this paper, we analyze applicability of tactile imaging for evaluation of reconstructive surgery results and characterization of normal and pelvic organ prolapse conditions. A pilot clinical study with 13 patients demonstrated that VTI allows imaging of vaginal walls with increased rigidity due to implanted mesh grafts following reconstructive pelvic surgery and VTI has the potential for prolapse characterization and detection.
