Head fixing device for PET examination

Abstract

The invention provides a head fixing device for PET examination. The head fixing device comprises a hood, a buffering layer and an external mechanical interface, the hood is made through 3D printing according to 3D scanning data of head form, the buffering layer is arranged on the inner side of the hood, the external mechanical interface is arranged on the hood, and the hood is fixedly connected with PET examination equipment outside through the external mechanical interface. The head fixing device can well fit with head form, thereby being high in matchability, and can balance requirements onfixity and comfort; the head fixing device is fixedly connected with the PET examination equipment outside through the external mechanical interface, and during PET examination, posture can be fixedwhile the head of an examination object does not need to be maintained static for a long time, and a user only needs to ensure the head to be relatively static to the PET examination equipment outside, so that the head fixing device is simple in operation and free of negative impact on experience of the examination object and examination treatment effect.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a head fixing device for PET inspection. Background technique [0002] PET (ie: Positron Emission Computed Tomography), the full name is Positron Emission Computed Tomography, is a common technique for brain imaging examinations in clinical departments such as internal and external departments. The traditional form of PET equipment is a push bed type. Lying on the push bed for examination. Use the headrest and the fixing strap to fix the patient on the hospital bed during the examination. At the same time, the patient should still be careful not to speak or move the body to avoid undesirable results such as blurring of the image. In addition, there are some non-traditional forms of PET equipment, such as brain-oriented PET, portable PET, and wearable PET. [0003] When the existing PET equipment is used, the head fixing method is relatively simple. The head rest genera...
