The calibration of CT Hounsfield units for radiotherapy treatment planning.

Computer tomographic (CT) scans are used to correct for tissue inhomogeneities in radiotherapy treatment planning. In order to guarantee a precise treatment, it is important to obtain the relationship between CT Hounsfield units and electron densities (or proton stopping powers for proton radiotherapy), which is the basic input for radiotherapy planning systems which consider tissue heterogenei...

Breakdowns ∗ Godfrey Keller

We study a continuous-time game of strategic experimentation in which the players try to assess the failure rate of some new equipment or technology. Breakdowns occur at the jump times of a Poisson process whose unknown intensity is either high or low. In marked contrast to existing models, we find that the cooperative value function does not exhibit smooth pasting at the efficient cut-off beli...

Genius explained

The physician's art is the catalogue of an exhibition of over 100 images and other objects from the collections of four North Carolina medical schools. In a finely-judged Preface, structured around specific examples shown, Martin Kemp points out some of the historical issues involved in the study of medical imagery and artifacts, beginning with the problem of what "realism" means in the context...

Investigation of the relationship between linear attenuation coefficients and CT Hounsfield units using radionuclides for SPECT.

This study has investigated the relationship between linear attenuation coefficients (mu) and Hounsfield units (HUs) for six materials covering the range of values found clinically. Narrow-beam mu values were measured by performing radionuclide transmission scans using (99m)Tc, (123)I, (131)I, (201)Tl and (111)In. The mu values were compared to published data. The relationships between mu and H...

Brain of the genius –

Our brain is a mystery organ. It is one of the most highly perfused organs of the body which metabolizes only glucose in presence of oxygen for its activity. Various parts of this soft organ inside our cranium are endowed with the responsibility for an individual’s intelligence, consciousnes, various talents and learning capacities, thoughts, etc. Different areas of our brain regulate and respo...
