Needle Insertion in CT Scanner with Image Overlay - Cadaver Studies
An image overlay system is presented to assist needle placement in conventional CT scanners. The device consists of a flat LCD display and a half mirror and is mounted on the gantry. Looking at the patient through the mirror, the CT image appears to be floating inside the patient with correct size and position, thereby providing the physician with two-dimensional “X-ray vision” to guide needle ...
متن کاملNeedle insertion in CT Scanner with Image Overlay - Phantom and Cadaver Studies -
We present an image overlay system that assists in surgical needle insertions inside conventional CT scanners. The device is mounted on the gantry of the CT scanner and consists of a flat LCD display and a semi-transparent mirror. In the preoperative calibration process the overlay system and the imaging plane of the scanner are registered. As a result, looking at the patient through the mirror...
متن کاملIRASIS : Insertion Robotisée d’Aiguille Sous Imagerie Scanner Robotized Needle Insertion with CT Guidance
This paper present the current state of the ROBEA project IRASIS whose goal is to design a robotic system for needle insertion under CT-guidance. To do so, a new stereotactic robotic needle positioning assistant for percutaneous procedures has been designed and built. This system, called the CT-Bot, is compatible with the medical requirements and offers an innovative approach to robotic needle ...
متن کاملImage overlay for CT-guided needle insertions.
OBJECTIVE We present a 2D image overlay device to assist needle placement on computed tomography (CT) scanners. MATERIALS AND METHODS The system consists of a flat display and a semitransparent mirror mounted on the gantry. When the physician looks at the patient through the mirror, the CT image appears to be floating inside the body with correct size and position as if the physician had 2D '...
متن کاملMRI image overlay: applications to arthrography needle insertion.
Magnetic Resonance Imaging (MRI) has unmatched potential for planning, guiding, monitoring and controlling interventions. MR arthrography (MRA) is the imaging gold standard to assess small ligament and fibrocartilage injury in joints. In contemporary practice, MRA consists of two consecutive sessions: 1) an interventional session where a needle is driven to the joint space and gadolinium contra...
