PROJECT TITLE :

Design and Fabrication of MR-Tracked Metallic Stylet for Gynecologic Brachytherapy

ABSTRACT:

Active magnetic resonance (MR) tracking for gynecologic brachytherapy was made possible by attaching the microradiofrequency coils to the brachytherapy applicator. The rectangular planar microcoil was fabricated using versatile printed circuits with dimensions of 8 mm × one.five mm. A 5-Fr (1.six mm) tungsten brachytherapy stylet was custom-machined to incorporate the microcoils. The finite component analysis and also the phantom tissue studies show that the proposed device enables in situ real-time guidance of access routes to the target anatomy safely and accurately. The setup was tested during a Siemens 3T MR scanner. The microcoils can be localized rapidly (up to forty Hz) and precisely (resolution: 0.half-dozen mm × 0.half-dozen mm × zero.six mm) using an MR-tracking sequence.
