Abstract
We introduce a novel image-guided puncture technique using C-arm cone-beam CT (XperCT) with fluoroscopic overlay puncture application (XperGuide) performed on the Allura Clarity angiography system (Philips Medical) for drainage or biopsy, compared with CT-guided puncture method. The puncture line can be determined with XperGuide by setting the Target Point and the Entry Point on XperCT images. These two points are overlapped in the fluoroscopic image in a “Bull′s Eye” fashion in the Entry View. We can puncture the needle at the Bull′s Eye point in the Entry View, and confirm the puncture distance in the Progress View to reach the Target Point. The advantages and disadvantages compared with the CT-guided procedure should be recognized to use XperGuide system well.
