AI Technical Summary
Existing thyroid nodule localization devices suffer from poor adaptability, insufficient comfort, low positioning accuracy, and issues such as radiation leakage risk and low marker recognition.
The circular main body adopts a nested telescopic structure. The inner layer is a cotton base with a silver ion antibacterial coating, the middle layer is a lead powder-bismuth oxide-epoxy resin composite polymer, and the outer layer is made of polyester fiber or PVC material. It is equipped with visual positioning marks to achieve dynamic adaptation and precise positioning.
It achieves multi-size adaptation, wearing comfort and radiation shielding stability, improves positioning accuracy to ≤0.1cm, reduces the risk of radiation leakage, and improves the recognition of markers in SPECT images.
