CT simulation-room head-neck fixing device

Abstract

The invention discloses a CT simulation-room head-neck fixing device. The CT simulation-room head-neck fixing device comprises head-neck-shoulder padding plates and a head-neck fixing part, wherein the head-neck fixing part comprises a head-neckthermoplastic film and clampingblocks, and the head-neck-shoulder padding platesinclude thehead-neck padding block and the shoulder padding block connectedwith the head-neck padding block; the inner contour of the head-neck padding block and the inner contour of the shoulder padding block are same as the inner contour of a head-neck padding plate of amagnetic-resonancehead-neck fixing device and the inner contour of a shoulder padding plate of the magnetic-resonancehead-neck fixing device in size; the head-neck padding block comprises an arc containing plate and an arc enclosing plate which is connected to the edge of the top wall of the arc containing plate and extends downwards to form enclosing of the arc containing plate; the height of thearc enclosing plate is larger than or equal to the height of the arc containing plate and is equal to the height of the shoulder padding block; locking mechanisms for fixing the head-neckthermoplastic film are installed at the portions, corresponding to locking parts of the magnetic-resonancehead-neck fixing device, of the top face of the arc containing plate; the shoulder padding block is an arcplate with a containing groove for containing the shoulder and back of a patient; shoulder pressing mechanisms for pressing the patient shoulders are installedon the arc containing plate and the arcenclosing plate which are located at the connection portion of the shoulder padding block.

Description

technical field [0001] The invention relates to a positioning device on CT scanning equipment and radiotherapy equipment in the medical field, in particular to a head and neck fixation device in a CT simulation room. Background technique [0002] After the clinical scan of the head and neck, in order to ensure the accuracy of the scanned image, the patient needs to be scanned again while maintaining the same position during the CT scan on the MRI, and the patient's lesion location can be determined by combining the images after the two scans. After determining the location of the lesion, the patient is kept in the same position for radiotherapy in the radiotherapy equipment. [0003] Because scanning and radiotherapy take a long time, and it is difficult for patients to maintain a position of the head and neck for a long time, the image consistency between CT scanning and MRI scanning is often affected due to positional movement, making the determination of the lesion locati...

Problems solved by technology

[0003] Because scanning and radiotherapy take a long time, and it is difficult for patients to maintain a position of the head and neck for a long time, the image consistency between CT scanning and MRI scanning is often affected due to positional movement, making the determination of the lesion location inaccurate , In addition, in the reset treatment, the inaccurate reset will affect the effect of radiotherapy, and even affect the normal cells
