GUIDABOT is developing robotic and imaging technologies to enable image-guided interventions (IGI) with real-time MRI (rtMRI) guidance. Interventions enabled by Guidabot’s patent pending technology will allow more efficient and safe tissue biopsy or delivery of brachytherapy seeds. Guidabot’s technology will enable a greater number of interventions to be performed by an imaging facility, thereby increasing throughput and associated revenue.
Magnetic resonance imaging (MRI) is often used to guide medical interventions including biopsies, laser ablations, and brachytherapy placement. However, current MRI guidance methods do not utilize real-time MR imaging and control,and thus are time-consuming and/ordo not provide optimal accuracyof needle placement. There is a need for a device that can manipulate a needle while using real-time MRI guidance, which will provide rapid, accurate needle placement in the target tissue.
GuidaBot is developing a robotic manipulator that is compatible with the strong magnetic field of MRI scanners. The device will enable physicians to remotely maneuver a needle (or other intervention tool) while simultaneously monitoring the position of the needle on the MRI display.The manipulator allows x-y positioning of the needle in a plane, as well as adjusting the angle of approach.This will provide more accurate targeting of needles in comparison to current procedures,meaningthat doctors can more effectively diagnose and treat cancers and other diseases. GuidaBot’s real-time image guidance willalso resultin shorter procedure times, improved patient comfort, and faster recovery, and will enable new procedures beyond current capabilities.
GuidaBot’s platform features a patent-pendingtechnology termed “solid-media transmission” (SMT), consistingof spherical beads andcylindrical spacers contained in channels andflexible tubing, which transmits force from the electric motorsto the manipulator. The SMT technology, which wasconceived by Dr. NikolaosTsekos at the University of Houston, enables the robotic device to be fully MRI-compatible.
Our target entry point is neurosurgical interventions including biopsies and laser ablationsof tumors. Due to the versatility of the GuidaBot platform, there is potential for performing a wide range of medical interventionsby substituting different intervention tools.The modular design of the GuidaBot platform will enable the same manipulator unit to access a wide range of organs, simplyby switching out the support frame.The GuidaBot device will be developed as an add-on to existing MRI scanners and as optional hardware bundled with new MRI scanners.GuidaBotis a joint venture between the University of Houston and Fannin Innovation Studio.
