A Dual-Modal CT/US Kidney Phantom Model for Image-guided Percutaneous Renal Access

The dual-modal CT/US kidney phantom model was created for developing and assessing solutions for image-guided percutaneous renal access. This phantom can be imaged through computed tomography (CT) and ultrasound (US) systems.

In short, the phantom is manufactured based on a porcine kidney combined with tissue mimicking material (TMM) and implanted fiducial markers (FMs). While the TMM mimics the surrounding tissues of the kidney, the FMs can be used to accurately align and assess the registration performance between US and CT images. Each phantom has 24 FMs.

Example of a ground-truth alignment for assessing registration between US and CT data. CT images, surfaces and associated FMs are represented by gray level images, green surfaces and points, respectively, while yellow and red are used to represent US images, surfaces and points.

This phantom has also the potential to be used for clinical training.
