Journal ArticleDOI
A New Type of Motor: Pneumatic Step Motor
TL;DR: The motor was designed to be compatible with magnetic resonance medical imaging equipment, for actuating an image-guided intervention robot, for medical applications, and is readily applicable to other pneumatic or hydraulic precision-motion applications.
Journal ArticleDOI
“MRI Stealth” robot for prostate interventions
Dan Stoianovici,Danny Y. Song,Doru Petrisor,Daniel Ursu,Dumitru Mazilu,Michael Mutener,Michael Schär,Alexandru Patriciu +7 more
TL;DR: The robot is the first to show the feasibility of fully automated in‐scanner interventions of MRI‐guided prostate interventions, and the challenges of MRI robot compatibility are given and the solutions adopted in making the MrBot are presented.
Journal ArticleDOI
Automatic Brachytherapy Seed Placement Under MRI Guidance
Alexandru Patriciu,Doru Petrisor,Michael Müntener,Dumitru Mazilu,Michael Schär,Dan Stoianovici +5 more
TL;DR: A robotic method of performing low dose rate prostate brachytherapy under magnetic resonance imaging (MRI) guidance, and results show outstanding image-guided needle and seed placement accuracy.
Journal ArticleDOI
Magnetic resonance imaging compatible robotic system for fully automated brachytherapy seed placement
Michael Müntener,Alexandru Patriciu,Doru Petrisor,Dumitru Mazilu,Herman S. Bagga,Louis R. Kavoussi,Kevin Cleary,Dan Stoianovici +7 more
TL;DR: The development of the first magnetic resonance imaging (MRI)-compatible robotic system capable of automated brachytherapy seed placement and it is believed that this robot may become a useful instrument for image-guided prostate interventions.
Journal ArticleDOI
MRI-Safe Robot for Endorectal Prostate Biopsy
Dan Stoianovici,Chunwoo Kim,Govindarajan Srimathveeravalli,Peter Sebrecht,Doru Petrisor,Jonathan A. Coleman,Stephen B. Solomon,Hedvig Hricak +7 more
TL;DR: The development of an MRI-Safe robot for direct (interventional) MRI-guided endorectal prostate biopsy is reported, and a comprehensive set of preclinical tests for MRI compatibility and needle targeting accuracy are presented.
