[0022] In this embodiment, the base layer 1 serves as the basic structure of the entire positioning patch, carrying other functional layers. The selection of non-woven fabric material ensures the softness, breathability and comfort of the base layer 1, which is suitable for long-term attachment to the patient's body surface, reducing allergies and discomfort. The base layer 1 is designed into two parts, corresponding to the imaging requirements of CT and MR examinations respectively. This layered design allows for dual imaging functions on the same positioning patch, meeting different examination needs without replacing the positioning patch, improving the examination efficiency and patient experience. The CT imaging grooves 4 and MR imaging grooves 5 are respectively arranged on the CT imaging layer 2 and the MR imaging layer 3, used for accurately placing the imaging agent, making the placement of the imaging agent more accurate and stable, helping to clearly display the lesion location in CT and MR images, and improving the diagnostic accuracy. The first elastic band 6 and the second elastic band 7 are detachably installed on both sides of the base layer 1, providing additional fixation and support for the positioning patch, significantly enhancing the adhesion of the positioning patch to the patient's body surface, effectively preventing detachment even when the limb or the examination bed moves, ensuring the continuity and accuracy of the examination, and improving the practicality and economy of the product.

[0023] In a further preferred embodiment of the present invention, fixing pieces 8 are fixedly installed on both sides of the base layer 1, and through holes 9 are respectively formed in the two fixing pieces 8 for the first elastic band 6 and the second elastic band 7 to pass through.
