Molecular imaging with targeted quantum dot bioconjugates: the need for contrast optimisation studies
Quantum dots have the potential to be used as contrast agents for molecular imaging in vivo, but there are many challenges in optimising such procedures, both in pre-clinical animal models and in the potential clinical applications. In particular, it is critical to obtain the optimal target-to-background contrast to achieve maximum diagnostic accuracy. However, available data are insufficient to ...

Monte Carlo studies of the eyelid's influence on the absorbed dose in eye tissues
The aim of this work was to investigate the influence of the eyelid on the absorbed dose distribution in eye tissues. The study was performed using two versions of the female adult head phantom (FeH) connected to the GEANT4 Monte Carlo code: one has the eyes open and the second, closed. The calculations of organ dose, normalised to air KERMA free-in-air, were done for external exposures to photon ...

Assessment of absorbed dose in digital and MIRD phantoms by MCNP in thorax area
This paper describes the development of mathematical models, called phantoms, for the assessment of absorbed doses caused by internal radionuclides. In more developed phantoms, anatomical models based upon 3D imaging methods are used. Cross-sectional anatomical models consist of numerous arrays of voxels, each of which individually corresponds to an organ. The digital phantom presented in this ...
