Robust landmark-based brain shift correction with a Siamese neural network in ultrasound-guided brain tumor resection

Author(s): Pirhadi A; Salari S; Ahmad MO; Rivaz H; Xiao Y;

Purpose: In brain tumor surgery, tissue shift (called brain shift) can move the surgical target and invalidate the surgical plan. A cost-effective and flexible tool, intra-operative ultrasound (iUS) with robust image registration algorithms can effectively ...

DiffeoRaptor: diffeomorphic inter-modal image registration using RaPTOR

Author(s): Masoumi N; Rivaz H; Ahmad MO; Xiao Y;

Purpose: Diffeomorphic image registration is essential in many medical imaging applications. Several registration algorithms of such type have been proposed, but primarily for intra-contrast alignment. Currently, efficient inter-modal/contrast diffeomorphic ...

Multimodal 3D ultrasound and CT in image-guided spinal surgery: public database and new registration algorithms

Author(s): Masoumi N; Belasso CJ; Ahmad MO; Benali H; Xiao Y; Rivaz H;

Purpose: Accurate multimodal registration of intraoperative ultrasound (US) and preoperative computed tomography (CT) is a challenging problem. Construction of public datasets of US and CT images can accelerate the development of such image registration tec ...
