Background Improvements in cancer survival have made the long-term risks from treatments
more important, including the risk of developing a second cancer after radiotherapy. We …

Effective dose from computed tomography (CT) examinations is usually estimated using the
scanner-provided dose-length product and using conversion factors, also known as k-factors…

Advances in Hodgkin lymphoma (HL) treatment have dramatically improved prognosis, with
5-year relative survival now over 80% in the United States (US) and Europe. However, …

The S values for 11 major target organs for I-131 in the thyroid were compared for three classes
of adult computational human phantoms: stylized, voxel and hybrid phantoms. In addition…

Organ dose estimation for retrospective epidemiological studies of late effects in radiotherapy
patients involves two challenges: radiological images to represent patient anatomy are not …

We developed models of lymphatic nodes for six pediatric and two adult hybrid computational
phantoms to calculate the lymphatic node dose estimates from external and internal …

The Thyrotoxicosis Therapy Follow-up Study (TTFUS) is comprised of 35,593 hyperthyroid
patients treated from the mid-1940s through the mid-1960s. One objective of the TTFUS was …

To improve the estimates of organ doses from nuclear medicine procedures using 131 I, the
authors calculated a comprehensive set of 131 I S values, defined as absorbed doses in …

Volumetric computed tomography dose index (CTDI vol) is an important dose descriptor to
reconstruct organ doses for patients combined with the organ dose calculated from …

To improve calibration methods of in vivo counting, our laboratory has developed a computer
tool to model internal contamination and assess in vivo activity and corresponding organ …
