Description

Nuclear magnetic coil flat bed for head and neck radiotherapy

Technical Field

The utility model relates to a radiotherapy field especially relates to a head and neck is nuclear magnetic coil flat bed for radiotherapy.

Background

With the development of precise radiotherapy technology, the method of determining the tumor form and the three-dimensional coordinate position of a patient by using an image acquired by a CT simulator is gradually replaced by a method of performing image fusion by using an image on an MR simulator and an image on the CT simulator, so as to realize more precise determination of the tumor form and the three-dimensional coordinate position. However, the MR simulator dedicated for radiotherapy is very expensive and cannot be popularized and applied. In order to solve the problem, the radiotherapy MR simulation positioning can be realized by modifying the existing image department equipment, and the realization mode of the technology is as follows:

1. the head coil on the original nuclear magnetic equipment for the image is removed, and the head of the patient fixed on a radiotherapy fixing plate and a radiotherapy positioning membrane cannot be plugged into the head coil for the nuclear magnetic equipment for the image together because the internal space of the original head coil is too small;

2. the flat bed is placed on a nuclear magnetic cambered surface bed, so that the flatness of the bed surface is ensured;

3. and a head coil fixing frame is arranged at the head position on the cambered surface bed, and the original small flexible coil of the imaging department is selected as the head nuclear magnetic coil.

4. And a body coil bracket is arranged at the body part position on the cambered surface bed, and a large flexible coil can be arranged on the body coil bracket and is used for scanning the body part of the patient.

However, this approach still has the following disadvantages:

1. because the original head coil is removed, a small flexible coil is adopted, only the front side has the coil, and the back brain part has no coil, so that the imaging degree of the skull base of the patient is not high.

2. The small flexible coil area is too small to cover the patient's neck, and therefore the imaging of the lymphatic region of the neck is not high.
