Parallel Integral Projection Transform for Straight Electrode Localization in 3-D Ultrasound Images

Popis výsledku v původním jazyce

In surgical practice small metallic instruments are frequently used to perform various tasks inside human body. We address the problem of their accurate localization in the tissue. Recent experiments using medical ultrasound have shown that this modalityis suitable for real-time visualization of anatomical structures as well as the position of surgical instruments. We propose an image processing algorithm that permits to automatically estimate the position of a line-segment shaped object. This method was applied to the localization of a thin metallic electrode in biological tissue. We show that the electrode axis can be found through maximizing the Parallel Integral Projection transform which is a form of the Radon transform. To accelerate this step hierarchical mesh-grid algorithm is implemented. Once the axis position is known, localization of the electrode tip is performed. The method was tested on simulated images, on ultrasound images of a tissue mimicking phantom containing a me
