One result of the risk assessment is the graphical representation of dose-response curve in which the likelihood of disease is presented as a function of levels of L. monocytogenes consumed (Figure 3.4).
More recently, a 3D high definition CT-scan based representation of dose-distribution superimposed with the posterior fossa structures, and tumour contour was made available.
To date, most UV system designs for air treatment have been based on empirical approaches, often involving crude representations of dose delivery and dose response behavior.
For this reason, it was found useful to provide a graphical representation of the dose inside the operating room, using iso-dose curves and making use of 2 different projections.
Because the BED incorporates factors related to delivery of treatment and tissue factors, it is a better representation of the dose delivered to a given tissue than conventional dose [ 6- 8].
It was especially designed for cutaneous melanoma treatments and, among its features, it provides a guide for the location and delineation of tumors and a visual representation of superficial dose distributions (for both tumor and normal tissues).
The treatment planning software performs thousands of computations per second to provide a three-dimensional composite graphical representation of the dose distribution on the CT images.
Based on this information, and the fact that the measured levels of BaP-DNA adducts showed dose-dependency and strong correlation with lacZ mutant frequency, it is safe to say that the BaP-DNA adduct levels at 28 days were at steady state, and the adduct levels measured at 72-hr post-exposure were a sufficiently accurate representation of BaP internal dose.
Seven TLDs were distributed throughout each right chest wall phantom to give adequate representation of measured radiation doses.
However, INR is not a linear representation of the coagulation and a dose-response curve has not been demonstrated in the literature [ 18, 19].
