Description

Screening can of examination room and imaging treatment system

Technical Field

The present disclosure relates to the field of medical devices, and more particularly, to an inspection room shield and an imaging treatment system.

Background

Magnetic resonance imaging is an advanced technique for imaging arbitrary sections of a human body by using a harmless nuclear magnetic method, and is performed by using nuclear magnetism of atoms. "nuclei" refer to hydrogen nuclei, and magnetic resonance imaging (Magnetic Resonance Imaging, abbreviated MRI) relies on hydrogen atoms in water, whereas about 70% of the human body is composed of water, and the human body is placed in a special magnetic field, and radio frequency pulses excite the hydrogen nuclei in the human body, causing them to resonate, and absorb energy. After stopping the radio frequency pulse, the hydrogen nucleus emits radio signal in specific frequency and releases the absorbed energy to be recorded by the receiver outside the body and processed by the computer to obtain the image. In the process, the electric signals released by the hydrogen atoms are very weak and are very easy to be interfered by the outside, so that high requirements are put on the construction of an examination room for magnetic resonance imaging.

Electromagnetic shielding becomes more complex when the magnetic resonance imaging apparatus is used in an examination room with other treatment apparatuses (e.g. radiotherapy apparatus, full scale radiation therapy device, RT for short). Other therapeutic devices (e.g., RT) may operate to produce electromagnetic interference with the magnetic resonance imaging device. Therefore, there is a need for improved screening of the examination room to shield electromagnetic interference generated by other therapeutic equipment to ensure that the magnetic resonance imaging apparatus operates in a space free of electromagnetic interference.

Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present specification, the drawings that are required to be used in the description of the embodiments will be briefly described below. It is apparent that the drawings in the following description are only some examples or embodiments of the present specification, and it is possible for those of ordinary skill in the art to apply the present specification to other similar situations according to the drawings without inventive effort. Unless otherwise apparent from the context of the language or otherwise specified, like reference numerals in the figures refer to like structures or operations.

It will be appreciated that "system," "apparatus," "unit" and/or "module" as used herein is one method for distinguishing between different components, elements, parts, portions or assemblies at different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.

As used in this specification and the claims, the terms "a," "an," "the," and/or "the" are not specific to a singular, but may include a plurality, unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that the steps and elements are explicitly identified, and they do not constitute an exclusive list, as other steps or elements may be included in a method or apparatus.

In recent years, magnetic resonance imaging has become a common medical imaging method. Magnetic resonance imaging is an advanced technique for imaging arbitrary sections of a human body by using a harmless nuclear magnetic method, and is performed by using nuclear magnetism of atoms. "nuclei" refer to hydrogen nuclei, and MRI relies on hydrogen atoms in water, whereas about 70% of the human body is composed of water, and the human body is placed in a special magnetic field, and radio frequency pulses excite the hydrogen nuclei in the human body, causing them to resonate, and absorb energy. After stopping the radio frequency pulse, the hydrogen nucleus emits radio signal in specific frequency and releases the absorbed energy to be recorded by the receiver outside the body and processed by the computer to obtain the image. In the process, because the electric signal released by the hydrogen atoms is very weak and is very easy to be interfered by the outside, the high requirement is put on the construction of a magnetic resonance machine room, and the shielding is required to be made. All existing magnetic resonance imaging devices need to work without radio frequency signal interference, and a conventional radio frequency shield is a regular hexahedral cube, so that the magnetic resonance imaging devices are wrapped in the shield.

Electromagnetic shielding becomes more complex when the magnetic resonance imaging apparatus has to be used in an examination room with other treatment apparatuses (e.g. radiotherapy apparatus, full scale radiation therapy device, RT for short). Other therapeutic devices (e.g., RT) may operate to produce electromagnetic interference with the magnetic resonance imaging device. Therefore, there is a need for improved screening of the examination room to shield electromagnetic interference generated by other therapeutic equipment to ensure that the magnetic resonance imaging apparatus operates in a space free of electromagnetic interference.

Some embodiments of the present description provide an examination room shield, and an imaging treatment system. The inspection chamber shield includes: the shielding assembly comprises a shielding side wall, a shielding top plate corresponding to the shielding side wall and a sub shielding assembly arranged in an inner space surrounded by the shielding side wall, wherein the shielding side wall is circumferentially closed. The sub-shield assembly includes a circumferentially closed sub-shield sidewall and a hollow sub-shield can. The hollow space of the sub-shield is used for installing the imaging device, and the sub-shield assembly is used for installing the treatment device. The shielding cover of the examination room has good shielding performance, not only wraps the magnetic resonance imaging equipment in a shielding space formed by surrounding the shielding side wall and the shielding top plate, but also effectively prevents signal interference of the outside of the examination room to the MR equipment, and wraps other treatment equipment in a shielding space formed by surrounding the sub-shielding side wall and the sub-shielding cover, so that electromagnetic interference generated by other treatment equipment is shielded, and the magnetic resonance imaging equipment is ensured to work in a space without electromagnetic interference. In some embodiments, a certain space is formed between the shielding side wall and the sub-shielding side wall, so that a communicated annular operation space is formed between the shielding side wall and the sub-shielding side wall, so that an operation space of an operator (for example, a doctor) in an examination room is larger, a walking path is more, the operator can rapidly cope with an emergency condition of a patient in an operation process (for example, the operator can rapidly walk to a head position from the left side and the right side of the patient, and a plurality of channels are convenient for a plurality of operators to walk at the same time, so that the occurrence of a phenomenon of collision of a plurality of people in an emergency situation is avoided).

The inspection chamber shield according to the embodiments of the present specification will be described in detail with reference to fig. 1 to 2. It is noted that the following examples are only for explaining the present utility model and are not to be construed as limiting the present utility model.
