Abstract
A disposable x-ray side marker (100) comprises a non-metallic material (108) having a sufficiently high linear attenuation coefficient to be radiographically visible. The material (108) may be mouldable, and may be or comprise gypsum. The material (108) may have an average atomic number greater than or equal to 11, and may have a linear attenuation coefficient greater than that of mammalian soft tissue.
Claims16
A disposable x-ray side marker comprising a non-metallic material having a sufficiently high linear attenuation coefficient to be radiographically visible, wherein the marker comprises a core at least partially surrounded by a sealing layer, wherein the sealing layer is arranged to act as a mould for casting of the core, and wherein the core is arranged to be retained within the mould.
A method of making a disposable x-ray side marker with no substantial metallic component, the method comprising:
- forming a sealing layer out of a first material, the first material having a low linear attenuation coefficient, wherein the sealing layer acts as a mould;
- at least partially filling the mould with a second material to form a core, the second material having a sufficiently high linear attenuation coefficient to be radiographically visible;
- and
- covering the filled mould with the first material.
