An automatic method for localizing radioactive seeds in implant dosimetry.
A method for locating radioactive seeds in interstitial implants has been developed that requires three radiographic views. Spatial coordinates for the seeds are computed from the randomly digitized seed images on each of three radiographs, and information about the tube and film placement for each of the radiographs. Further, the ability to accurately (greater than 98% of the seeds within +/- 2.5 mm) locate the seeds does not require the use of a specialized radiographic technique; the radiographs need only represent three different views of the implant. Also discussed is the seed image matching technique that enables ambiguous seed matches to be resolved.
