目的开发一个标准化的数字报告工具，膀胱镜检查的膀胱全景imaging.MATERIALS和方法的图像处理和拼接软件（Endorama）的膀胱镜检查数据生成全景图像。在处理阶段，通过参考膀胱镜检查序列（n = 30）对算法进行调制和改进。随后，标准的系统膀胱镜检查（n = 12）记录在接受经尿道膀胱肿瘤切除术的患者，以创建全景images.Results所有序列适用于软件的开发和改进。处理越来越多地允许创建图像，说明膀胱的大部分和不同位置的相关解剖标志。在相应的数字图像中，将介入期间内窥镜覆盖的路径显示为路径。在应用阶段，12例病例中有10例成功创建了全景图像。图像的分辨率为4096 x 2048像素，图像需要3.9 MB（3.4-5.7）的中值数字存储器。全景图像显示了22个相关的发现，其中7个乳头状tumors.Conclusion高品质的数字全景地图的膀胱使用专门处理的数据，视频膀胱镜。在这一初步系列中，相关发现在相应的图像中得到了说明。我们的工具可能有助于提高膀胱镜检查报告的标准化，并减少观察者之间的差异。(C)2017爱思唯尔公司
OBJECTIVE To develop a standardized digital reporting tool for cystoscopy of the urinary bladder using panoramic imaging.MATERIALS AND METHODS An image processing and stitching software (Endorama) was developed to generate panoramic images from cystoscopy data. In a processing phase, algorithms were modulated and refined by reference to cystoscopy sequences (n = 30). Subsequently, standard systematic cystoscopies (n = 12) were recorded in patients undergoing transurethral resection of a bladder tumor to create panoramic images.RESULTS All sequences were applicable for the development and refinements of the software. Processing increasingly allowed the creation of images illustrating large parts of the bladder and relevant anatomic landmarks in different locations. The pathway covered by the endoscope during the intervention was illustrated as a route in the respective digital image. During the application phase, panoramic images were successfully created in 10 out of 12 cases. The resolution of the images was 4096 x 2048 pixels and the images required a median digital memory of 3.9 MB (3.4-5.7). The panoramic images illustrated 22 relevant findings of which 7 were papillary tumors.CONCLUSION High-quality digital panoramic maps of the urinary bladder were created using specifically processed data of videocystoscopy. In this preliminary series, relevant findings were illustrated in the respective image. Our tool may help improve standardization of cystoscopy reports and reduce interobserver variability.
