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...

Setiap personil radiasi yang melakukan pelayanan radiodiagnostik wajib menggunakan monitor personal dosimetry. tetapi karena harganya mahal, tidak semua personel pekerja difasilitasi oleh tempat bekerjanya. Tujuan penelitian ini adalah membuat desain pengembangan alat Imaging Plate (IP). Jenis jenis Research and development dengan pendekatan eksperimental dan dianalisa secara deskriptif. Hasil ...

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...

Fluorescence Nuclear Track Detectors (FNTDs) are part of a new technology developed for particle detection and applicable to personal neutron dosimetry. The objective this study is simulate the FNTD fast response to: (i) assess understand performance existing dosimeter design (Landauer Inc.) its associated single layer track-spots analysis; (ii) evaluate potential information that can be obtain...

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...

The high flux density of synchrotron white beam offers several advantages in X-ray imaging such as higher resolution and signal-to-noise ratio 3D/4D micro-tomography, frame rate real-time transient phenomena, penetration thick dense materials especially at energies. However, these come with additional challenges to beamline optics, camera sample due increased heat load radiation damage, persona...
