Abstract

The invention provides a single belt drive and a floating hook module for a conformal microwave array (CMA) based MRI system. The floating hook module is hard mounted to bottom of a bridge. A motor fixed to the rear bridge provides the drive to the belt. The floating hook is attached to free end of the belt and is guided in pultruded channels fixed to bridge. The entire drive is compactly packaged to have very minimal installed height, which fit well between the bridges below the CMA coil and bore.

SUBMERGED SINGLE BELT DRIVE FOR CONFORMAL MICROWAVE ARRAY (CMA) BASED MAGNETIC RESONANCE SYSTEM

FIELD OF INVENTION

The invention generally relates to a magnetic resonance (MR) system and more particularly to single belt drive system for the magnetic resonance system.

BACKGROUND OF THE INVENTION

A belt drive system allows a cradle to move in and out for a conformal microwave array

(CMA) based MRI system. Design architecture includes in and out drive system that suffer critical drawback to support the cradle drive for the CMA based MRI system. A drive system includes elements like belt, latch hook on bridge and are exposed. This increases thickness and weight of tabletop, which increases height and magnetic parts on table, poses serious concern for a mobile version table. This is mainly due to requirement of the table to move around in bay with magnetic parts. The table length increases to accommodate the drive on table, which again poses difficulty for architecture for the mobile version table.

A conventional technique includes a dual belt drive system for lateral posterior choroidal arteries (LPCA) drive on a rear pedestal. However, the convention technique increases length of the rear pedestal due to presence of LPCA on bridge and does not provide open bore view to a patient.

Another conventional technique includes a rigibelt or two-layer drive is utilized on the table to drive the cradle. The conventional technique increases the tabletop thickness, which increases height of table and makes the table longer and heavy unsuitable for mobile MR system.

Another conventional technique includes cradle-transferring device with shuttle table for moving the cradle. However conventional technique increases thickness of the tabletop.

Yet another conventional technique includes a cradle drive mechanism which includes a drive motor, an intermediate frame and a screw and nut transmission device driven by the drive motor. However, the conventional technique increases thickness of tabletop.

Hence there exists a need for an efficient technique to maintain minimum tabletop height of the CMA based MRI system.
