Abstract

The utility model relates to a magnetic resonance image-forming system. The utility model is composed of an upper magnetic pole, a lower magnetic pole, a vertical column, a multiway movable sick bed, etc. The upper magnetic pole and the lower magnetic pole are supported by the vertical column. The sick bed is positioned between the upper magnetic pole and the lower magnetic pole. The vertical column which supports the upper magnetic pole and the lower magnetic pole is provided with a window. One side of the vertical column which is correspondingly sealed is converted into a magnetic resonance image-forming system with high open degree. The doctors and the nurses approach to the patients from front and back, left and right, which is convenient for the intervention operative treatment.

Description

A kind of magnetic resonance imaging system

This utility model relates to a kind of magnetic resonance imaging system (hereinafter to be referred as the MRI system) of the C of having type magnet, is applicable to the medical imaging diagnosis field.

The MRI system is a kind of novel medical imaging diagnosis equipment that grows up the early 1980s.It can provide the faultage image of human body, but does not use X ray, and is very safe to patient and staff; Its uses the NMR signal of human body fluid, and the diagnosis of soft tissue is had special sensitivity; It can not only provide the anatomic information of human body, and some pathological informations can also be provided, thereby more favourable to the diagnosis pathological changes.Its appearance has obtained clinician's generally approval, is considered to one of state-of-the-art medical imaging diagnosis equipment.

The magnet bore structure of sealing around traditional MRI system has.Patient lies in and enters magnet bore on the sick bed and scan.In this environment, patient feels uncomfortable in chest, constrains through regular meeting, even brings out claustrophobia.In addition, because the development of interventional medicine presses for the condition that the MRI system can provide medical worker and patient directly to contact, even require in magnet bore, to finish operation.Traditional MRI system is powerless to this.Since 1994, having occurred a kind of MRI system (Fig. 1) of C type magnet structure in the world, is representative with the Magnetom OPEN of SIEMENS and the Outlook of PICKER, has overcome the shortcoming of traditional MRI system preferably.The magnet A of this MRI system is supported polar single upright column (3) and is constituted by last lower magnetic pole (1) and (2); Sick bed B is made of base (4), bedstead (5) and bed board (6), and bedstead (5) can be gone up at base (4) along directions X and move; Bed board (6) can be gone up at bedstead (5) along the Y direction and move, and scanography is accepted in the center that patient sends between lower magnetic pole (1) and (2).But the magnet of this structure is not enough in a side openness of column (3), and the medical worker can only make troubles to operation in a side of sick bed when doing interventional therapy or operation.And moving of sick bed also is subjected to certain restriction.

The purpose of this utility model is to have overcome above-mentioned defective, provides a kind of openness height, easy to operate magnetic resonance imaging system.

Technical solution of the present utility model is achieved in that a kind of by last magnetic pole, lower magnetic pole, column and the magnetic resonance imaging system formed of sick bed movably, last lower magnetic pole passes through upright supports, sick bed is between last lower magnetic pole, it is characterized in that: about supporting, have a window on the polar column, the column of an original side relative closure is become the magnetic resonance imaging system with higher openness, make that doctor and nurse can be near patients from about the front and back.

This utility model feels more open owing to adopt said structure to make patient when carrying out scanography, has also made things convenient for the interchange between the doctors and patients; When implementing interventional therapy or operation, the medical worker can make things convenient for the carrying out of intervene operation from more direction near patient.

Accompanying drawing 1 is the MRI system schematic of single upright column C type magnet.

Accompanying drawing 2 is structural representations of the present utility model.

Below in conjunction with drawings and Examples this utility model is described in further detail.

In accompanying drawing 2, a kind of magnetic resonance imaging system mainly is made up of parts such as last magnetic pole 1, lower magnetic pole 2, column 3.1 and 3.2, sick beds 4, last lower magnetic pole passes through upright supports, sick bed 4 is between last lower magnetic pole, on supporting, have a window 5 on the column of magnetic pole 1, lower magnetic pole 2, formed two columns (3.1 and 3.2) independently separately, made that the side at the magnet column has higher openness.After having a window on the column, sick bed has utilized the characteristics of twin columns C type magnet, makes sick bed move through window (5) along directions X.Doctor and nurse can have positive meaning for interventional therapy or operation near patient from about the front and back.

Claims (1)

1, a kind of by last magnetic pole (1), lower magnetic pole (2), column (3) and a kind of magnetic resonance imaging system of forming of sick bed (4) movably, last lower magnetic pole (1,2) supports by column (3), sick bed (4) is between last lower magnetic pole, it is characterized in that: column (3) has window (5), but sick bed is along this window moving linearly.
