Directable Needle Guide: Efficacy for Image-Guided Percutaneous Interventions
Diagnostic and therapeutic image-guided percutaneous interventions have become increasingly important in the clinical management of various conditions. Though precise needle placement via a safe route is essential for successful percutaneous interventions, it is often difficult in cases of deeply situated, small lesions. The present paper describes the efficacy of the directable needle guide (D...
متن کاملInterventional Radiology Robot for CT and MRI Guided Percutaneous Interventions
This paper introduces a new patient-mounted CT and MRI guided interventional radiology robot for percutaneous needle interventions. The 5 DOF robot uses ultrasonic motors and pneumatics to position the needle and then insert it progressively. The needle position and inclination can be registered in the images using two strategically placed fiducials visible in both imaging modalities. A first p...
متن کاملDesign of an Instrument Guide for Mri-guided Percutaneous Interventions
This paper describes the design of an instrument guidance device for percutaneous interventions in closed bore magnetic resonance (MR) imaging systems. The device consists of a curved arm piece that travels around a circular base, and an additional needle holder that travels along the curved arm – thus providing two angular degrees of freedom that enable an ablation probe to pivot about a remot...
متن کامل6 MRI-guided Interventions
After mammography and ultrasound (US), magnetic resonance imaging (MRI) of the breast is the third diagnostic imaging technique used in the diagnostic work-up of breast findings. In contrast to the other techniques, MRI primarily gives information on the vascularization of intramammary structures. Because malignant tumors typically have an increased vascularization attributed to tumor neoangiog...
متن کاملManually Steerable Catheter With Improved Agility
Purpose A prototype steerable catheter was designed for endovascular procedures. This technical pilot study reports the initial experience using the catheter for cannulation of visceral arteries. Technique The 7F catheter was manually steerable with operator control handle for bending and rotation of the tip. The maximum bending angle was approximately 90° and full 360° rotation of the tip wa...
