OPEN ARCHITECTURE IMAGING APPARATUS AND COIL SYSTEM FOR MAGNETIC RESONANCE IMAGING
First Claim
1. A variable angle guide plug holder system for use in interventional procedures, comprising:
- a guide plug holder for receiving an angular determination fixture;
the guide plug holder movable relative to the angular determination fixture between a plurality of positions, each position providing a different angle of insertion relative to a point of origin on the angular determination fixture;
a plate plug portion removeably engaged with the angular determination fixture;
a guide plate having a plurality of guide plate apertures, wherein the guide plug holder is insertable into a respective guide plate aperture; and
a medical instrument for use in an interventional procedure, configured to be inserted into the respective guide plate aperture at a respective angle of insertion.

Abstract
This invention discloses a method and apparatus to deliver medical devices to targeted locations within human tissues using imaging data. The method enables the target location to be obtained from one imaging system, followed by the use of a second imaging system to verify the final position of the device. In particular, the invention discloses a method based on the initial identification of tissue targets using MR imaging, followed by the use of ultrasound imaging to verify and monitor accurate needle positioning. The invention can be used for acquiring biopsy samples to determine the grade and stage of cancer in various tissues including the brain, breast, abdomen, spine, liver, and kidney. The method is also useful for delivery of markers to a specific site to facilitate surgical removal of diseased tissue, or for the targeted delivery of applicators that destroy diseased tissues in-situ.
