Implantable or insertable nuclear magnetic resonant imaging system

摘要

Nuclear Magnetic Resonant Imaging (also called Magnetic Resonant Imaging or “MRI”) devices which are implantable, internal or insertable are provided. The disclosure describes ways to miniaturize, simplify, calibrate, cool, and increase the utility of MRI systems for structural investigative purposes, and for biological investigation and potential treatment. It teaches use of target objects of fixed size, shape and position for calibration and comparison to obtain accurate images. It further teaches cooling of objects under test by electrically conductive leads or electrically isolated leads; varying the magnetic field of the probe to move chemicals or ferrous metallic objects within the subject. The invention also teaches comparison of objects using review of the frequency components of a received signal rather than by a pictorial representation.

主权项

1. A method of cooling an insertable, movable, or implantable magnetic resonant imaging (MRI) system comprising:
inserting or moving an MRI device or a portion thereof; cooling the inserted MRI device or a portion thereof by use of an extrinsic cooling unit leads which remove heat from the inserted MRI device by thermal conduction, convection or radiation; and providing a series of tubing leads filled with an electrically conductive fluid which conducts electricity to and from the inserted MRI device.
