Monte Carlo water-equivalence study of two PRESAGE® formulations for proton beam dosimetry T Gorjiara, Z Kuncic, J Adamovics and C Baldock 2013 J. Phys.: Conf. Ser. 444 012090 PRESAGE® is a radiochromic solid dosimeter which shows promising potential for 3D proton beam dosimetry. Since an idea dosimeter should be water-equivalent, total depth dose distributions in two PRESAGE® formulations irra...

Electronic portal imaging devices (EPIDs) have been the preferred tools for verification of patient positioning for radiotherapy in recent decades. Since EPID images contain dose information, many groups have investigated their use for radiotherapy dose measurement. With the introduction of the amorphous-silicon EPIDs, the interest in EPID dosimetry has been accelerated because of the favourabl...

Hematologic toxicity limits the radioactivity that may be administered for radiolabeled antibody therapy. This work examines approaches for obtaining biodistribution data and performing dosimetry when the administered antibody is known to bind to a cellular component of blood, bone, or marrow. Marrow dosimetry in this case is more difficult because the kinetics of antibody clearance from the bl...

Introduction: Use of SPECT/CT data is the most accurate method for patient-specific internal dosimetry when isotopes emit single gamma rays. The manual or semi-automatic segmentation of organs is a major obstacle that slows down and limits the patient-specific dosimetry. Using digital phantoms that mimic patient’s anatomy can bypass the segmentation step and facilitate the dosi...

Abstract In this review, we discuss the value of biological dosimetry and electron paramagnetic resonance (EPR) spectroscopy in medical management support acute radiation syndrome (ARS). Medical an ionizing scenario requires significant information. For optimal aid, information has to be rapidly (< 3 days) delivered health-care provider. Clinical symptoms may initially enable physicians pred...

Dosimetry for targeted radionuclide therapy is a relatively young field. Although initial work can be traced back to the late 1940s (1), the MIRD Committee formalism that forms the foundation for most current approaches was published in the mid 1970s (2), and the drive for improved dosimetry to meet the requirements of targeted radionuclide therapy did not begin until the 1980s. During this per...
