Head fixing device for PET (positron emission tomography) examination

Abstract

The invention discloses a head fixing device for PET (positron emission tomography) examination. The head fixing device comprises a fixed plate, moving side plates, a driving part, a cloth mask and hook-and-loop fasteners. The fixed plate is connected to the middle of one end, corresponding to a human head, of a PET examination bed and extends outwards along the length direction of the PET examination bed. The moving side plates are symmetrically hinged to two lateral sides of the fixed plate and in shapes of arc plates protruding outwards. The driving part is arranged on the lower surface ofthe fixed plate and connected with outer surfaces of the two moving side plates and operates to make free ends of the two moving side plates get close to or away from each other. The cloth mask can cover the human head by sleeving. The hook-and-loop fasteners include first loop faces and first hook faces, the first loop faces and the first hook faces can be adhered, the first loop faces are positioned on the inner surfaces of the moving side plates, and the first hook faces are at least distributed on surfaces, corresponding to the rear side and two lateral sides of the head, of the cloth mask. By the head fixing device for PET examination, universality and safety in head fixing of patients are realized, PET examination is facilitated, and PET examination quality is improved.

Description

technical field [0001] The invention relates to the technical field of PET inspection, in particular to a head fixing device for PET inspection. Background technique [0002] PET (ie: positron emission tomography), the full name of positron emission tomography imaging, is a common technique for clinical brain imaging examinations in departments of internal medicine and external surgery. The duration of a PET examination is usually about 10-25 minutes. In order to ensure the imaging quality of the examination and provide a reliable basis for diagnosis, the patient lying on the PET examination bed is usually required not to move his head during the examination. In the case of not using external means, it is difficult for the patient to keep the head still for a long time, which brings many uncertain factors to the PET examination. In clinical operations with similar actions such as fixed radiotherapy, a plastic mesh helmet is custom-made for each patient according to the head...

Problems solved by technology

In the case of not using external means, it is difficult for the patient to keep the head still for a long time, which brings many uncertainties to the PET examination.

In clinical operations with similar actions such as fixed radiotherapy, a plastic mesh helmet is custom-made for each patient according to the head shape of the patient, so that after the patient wears the mesh helmet, the head can be fixed on the equipment for a long time to achieve the desired effect. However, this method has too much investment and brings a huge economic burden to patients, and it is not suitable for promotion.
