Description

基于OCT图像提取骨磨削或消融后表面粗糙度的方法
技术领域
本发明涉及骨艺术品加工和骨疾病外科治疗领域，特别涉及一种能够用于测量骨磨削或消融后表面粗糙度的方法。
背景技术
骨是一种坚硬的***，也是由细胞、纤维和基质构成包括但不限于牙齿、颅骨、颌骨、腿骨。磨削或消融是骨常用地处理方法，应用在骨艺术品加工和骨疾病外科治疗过程中。骨表面粗糙度的测量对于评价骨的力学性能和耐腐蚀性能具有重要意义。骨表面粗糙度的测量对于认识骨表面超微结构具有促进作用。对于人工骨，表面粗糙度与其生物相容性密切相关。
发明内容
本发明就是针对上述问题，提供了一种基于光学相干成像（OCT）技术的解决方法。
OCT成像是一种公认的非入侵光学成像方法；能够无损的获取物体的断层图像，OCT图像的强度正相关于物质光散射特性的强弱；OCT图像的范围足够骨检测；OCT图像的分辨率10微米左右，能够保证表面粗糙度测量的精细度。
空气和水的光散射能力非常弱，OCT图像强度低；骨的散射能力较强，OCT图像中强度高。
本发明的方法需要如下的工序：在骨磨削或消融处理过程中或过程后，采用OCT成像***获取组织的断层图像。
根据所述的OCT图像，利用骨的图像强度高于空气的特点，可以利用图像二值化处理并进行膨胀腐蚀操作然后提取得到骨的边界线，可以将边界线标注在OCT图像上。
根据所述OCT图像上标注的骨的边界线，可以利用多项式对基线进行校准。
根据所述OCT图像上标注的骨的边界线，进行过一次基线校准后，可以利用算术平均中线进行二次基线校准。
根据所述OCT图像上标注的骨的边界线，进行过两次基线校准后，可以根据表面粗糙度评定参数的公式计算得到表面粗糙度的评定参数。
最后将所述测量的骨的表面粗糙度信息记录和显示。
本申请方法可以在骨的处理过程中或者之后监控组织的表面粗糙度，是一种准确、快速、无创的方法。
