The Paris system of Dosimetry can be utilized with which of the following?

The Paris system of dosimetry is designed for use in brachytherapy, particularly for the planning and evaluation of implantable sources used in internal radiation treatments. This system can effectively apply to a variety of sources, including 192Ir wires, ribbons, and HDR (high-dose-rate) sources.

The adaptability of the Paris system allows clinicians to assess the dosimetric characteristics of these various configurations of 192Ir. For instance, 192Ir wires and ribbons can be utilized in both temporary and permanent implant treatments, where the geometry and distribution of the sources can significantly impact the dose distribution. Similarly, 192Ir HDR sources are commonly employed in modern brachytherapy, allowing for precise dose delivery with a high degree of control over timing and intensity.

Thus, the Paris system's comprehensive approach and its algorithms are applicable across all these forms of 192Ir. By employing this system, dosimetrists can ensure that the radiation dose is adequately calculated for effective treatment, regardless of the source configuration, highlighting the versatility and scope of the Paris system in clinical practice.
