Magnetic resonance head and neck immobilization device

Abstract

The invention discloses a magnetic resonance head and neck fixing device, which comprises a head and neck shoulder pad and a head and neck fixing part; the head and neck fixing part comprises a head and neck thermoplastic film and a clamping block; Shoulder pads; when the head and neck pads and shoulder pads are used, they are placed in the head and neck joint coil and fit with the inner surface of the head and neck joint coil; the head and neck pad includes an arc-shaped support plate for supporting the head and neck and At least one arc-shaped enclosing board is connected to the edge of the arc-shaped supporting plate and extends upward; the inner surface of each arc-shaped enclosing board is provided with a locking part for fixing the head and neck thermoplastic film; the shoulder pad includes the shoulder and back A support plate and an arc-shaped plate, the arc-shaped plate is connected to the edges of the shoulder-back support plate and the head-neck support plate, and is enclosed with the shoulder-back support plate to form an accommodation cavity for accommodating the shoulders; the arc-shaped plates located on both sides of the head-neck support plate A mounting plate extending toward the head and neck pad is connected, and the mounting plate is equipped with a shoulder pressing mechanism for pressing the patient's shoulder.

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 fixing device. Background technique [0002] Compared with CT, MRI has high soft tissue resolution and no radiation, and can provide rich anatomical and functional imaging information, such as anatomical site, physiological metabolism, and body function. , efficacy prediction, etc. With the development of precision radiotherapy, high-quality magnetic resonance image quality and precise localization are essential. [0003] In order to improve the quality and accuracy of magnetic resonance images, there are existing scans that use a combined head and neck coil to scan images. When a combined head and neck coil is used for scanning, the patient's head, shoulders and neck do not directly contact the plastic shell of the combined coil, but lie on a soft The protective pad made of elastic material can improve the comfort...

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
