    • According to exemplary embodiments of the present disclosure, apparatus, device and method can be provided which can provide imaging of biological tissues, e.g., luminal organs in vivo, using optical techniques in an automatic or semiautomatic manner. The exemplary apparatus, device and method can utilize a tethered capsule catheter with a mechanism for manual, semi-automatic or automatic traversing in the luminal organ with a controlled velocity and/or image quality. The exemplary apparatus can include feedback information about tension applied to the catheter during its movement that can be used to adjust velocity and assure patient comfort and safety for example during passing through natural sphincters and/or narrowing of the luminal organs and preventing from breaking of the catheter. The exemplary apparatus can also adjust velocity in order to provide good quality of acquired images, for example to engaged peristalsis and provide contact with the tissue. In one exemplary embodiment of the present disclosure, the exemplary mechanism for a controlled advancement of the catheter can be positioned outside of the patient's mouth, and can include a position sensor providing information about the position of the capsule in respect to the luminal organ for orientation of the acquired data.

    • Embodiments of the present disclosure provide a software program that displays both a volume as images and segmentation results as surface models in 3D. Multiple 2D slices are extracted from the 3D volume. The 2D slices may have different locations and orientations and also may be moved using a mouse, touchscreen, and/or keyboard by a user. The 2D slices may be interactively rotated by the user to best follow an oblique structure. The 2D slices can "cut" the surface models from the segmentation so that only half of the models are displayed. The border curves resulting from the cuts are displayed in the 2D slices, enabling evaluation of surface accuracy against the raw image data in any plane. The user may click a point on the surface model to designate a landmark point. The corresponding location of the point is highlighted in the 2D slices. After the user has picked two landmark points to determine a line, a 2D slice can be reoriented such that the line lies in the slice. The user can then further evaluate/refine the landmark points based on both surface and image information.
    • 本公开的实施例提供一种软件程序,其将作为图像和分割结果的体积显示为3D中的表面模型。 从3D体积中提取多个2D切片。 2D切片可以具有不同的位置和取向,并且还可以由用户使用鼠标,触摸屏和/或键盘来移动。 2D切片可以由用户交互地旋转以最好地遵循倾斜结构。 2D切片可以从分割“切割”表面模型,使得只显示一半的模型。 由切割产生的边界曲线显示在2D切片中,可以对任何平面中的原始图像数据进行表面精度的评估。 用户可以点击表面模型上的一个点来指定里程碑点。 点的相应位置在2D切片中突出显示。 在用户选择两个地标点以确定线之后,可以重新定向2D切片,使得线位于切片中。 然后,用户可以基于表面和图像信息进一步评估/细化地标点。
