Magnetic-resonance head-neck fixing device

Abstract

The invention discloses a magnetic-resonance head-neck fixing device. The magnetic-resonance head-neck fixing device comprises head-neck-shoulder padding plates and a head-neck fixing part; the head-neck fixing part comprises a head-neck thermoplastic film and clamping blocks; the head-neck-shoulder padding plates include the head-neck padding plate and the shoulder padding plate connected with the head-neck padding plate; the head-neck padding plate and the shoulder padding plate are put into a head-neck combining coil during using, and are attached to the inner surface of the head-neck combining coil; the head-neck padding plate comprises an arc supporting plate for supporting the head neck part, at least one edge connected to the arc supporting plate and arc enclosing plates extending upwards; a locking part for fixing the head-neck thermoplastic filmis installed on the inner surface of each arc enclosing plate; the shoulder padding plate comprises a shoulder-back supporting plate and arc plates, the arc plates are connected to the edge of the shoulder-back supporting plate and the edge of the head-neck padding plate, a containing cavity for containing the shoulder and the backis enclosed through the arc plates and the shoulder-back supporting plate; installing plates extending in the direction of the head-neck padding plate are located on the arc plates on the two sides ofthe head-neck padding plate, and shoulder pressing mechanisms for pressing the shoulders of a patient are assembled on the installing plates.

Description

technical field [0001] The invention relates to magnetic resonance auxiliary equipment in the medical field, in particular to a magnetic resonance head and neck fixation device. Background technique [0002] Compared with CT, magnetic resonance imaging has high soft tissue resolution and no radiation, and can provide rich anatomical and functional imaging information, such as anatomical parts, physiological metabolism and body functions, etc., and is currently widely used in radiotherapy tumor differential diagnosis and target delineation , curative effect prediction and so on. With the development of precision radiotherapy, high-quality magnetic resonance image quality and precise positioning are essential. [0003] In order to improve the quality and accuracy of magnetic resonance images, there are existing scans that use the combined head and neck coil for image scanning. When using the combined head and neck coil for scanning, the patient's head, shoulders and neck do n...

Problems solved by technology

[0004] However, due to the long time of the MRI examination, the patient's head and neck will inevitably move a little, which will affect the quality of the MRI image; in addition, it is difficult to accurately locate the tumor lesion on the scan image when performing reset treatment based on the scan image. The positioning position of the image, which makes it affect the later treatment effect
