AI Technical Summary

Problems solved by technology

However, such methods may not be accurate or reliable in determining the correct location of the radioactive source
Additionally, traditional markers may not be usable across multiple different imaging modalities
For example, markers compatible with CT imaging may not be compatible with those used for magnetic resonance imaging (MRI)

Abstract

Embodiments of the present disclosure may relate to brachytherapy markers. An exemplary marker may include an inner ring composed of one or more of copper, brass, gold, silver, or titanium; an overcoat layer consisting of one or more of nickel or iron oxides wherein the overcoat layer may have a thickness of from about 1 [mu] m to about 30 [mu] m; and a central opening, where the diameter of the central opening may be from about 0.50 mm to about 3.00 mm.

Description

Technical field [0001] The present disclosure generally relates to a short-distance radiation therapy, and in particular, to the close-range radiation therapy label designed to be used across multiple imaging modes. Background technique [0002] During high-dose rate (HDR), the radiation source is introduced or adjacent to the patient's target volume, for example, a tumor. The radiation source can be introduced manually or by using the afterLoader device. Typically, the rear load device is used to deliver the radiation source to the patient's internal area to the patient in a given period of time. The radiation source can be introduced via a cable or catheter, and may be positioned within a projection of a projection in the patient, and the projection of the drug is pre-positioned in the patient. [0003] The exact positioning of the radiological source in the target area of ​​the body is important for the administration of the predetermined proximal radiation therapy. For exampl...
