Two experimental dynamic phantoms have been used for studying temperature distributions induced by interstitial ferromagnetic implant hyperthermia at various blood perfusions, Curie point implants, and input power levels. One of the phantoms is an axially perfused hollow cylinder filled with 3 mm diameter glass beads, and the other is a similar cylinder model that is radially perfused. Analytic models have been developed for evaluating temperature profiles within the two phantoms. Experimental results from the phantoms compare reasonably well with the analytical results. A qualitative comparison is made between thermal profiles derived from both a convection energy equation, for a homogeneous porous medium, and a bioheat transfer equation. The adequacy of using a porous material for simulating living tissue is discussed. Parametric studies showing the effects of various implant parameters such as Curie point and applied power are analyzed.

Assessment of body fat percentage is desirable to identify health risks associated with obesity. There are few studies that have compared the assessment of body fat between air displacement plethysmography and dual-energy x-ray absorptiometry, particularly related to age and gender differences. The purpose of this study was to determine if body fat percent estimates differ depending on age and/or gender between air displacement plethysmography (Bod Pod, Life Measurements Instrument, Concord, CA) and dual-energy x-ray absorptiometry (DEXA, General Electric Medical Systems, Lunar Prodigy, Madison, WI). Sixty subjects were studied: 15 men and 15 women, 22-35 years and 15 men and 15 women, 55-80 years. Subjects were excluded if they competed in athletics or high-level exercise training in the last year. Standard calibration and testing procedures were used for both methods. Both methods were administered at least twice to evaluate reliability and were repeated a third time if the first two measures differed by >2%. Differences between methods for age groups and gender were analyzed using ANOVA and reliability comparisons between the body composition methods were evaluated with correlation coefficients and Bland-Altman plots. Using data for all subjects, DEXA (r = .996) and Bod Pod (r = .985) both showed good reliability. However, in younger females the reliability of the Bod Pod (r = .911) was lower. Sixteen of the 60 subjects required a third trial for the Bod Pod, whereas all repeated DEXA measures were consistent. The deviation between trial 1 and 2 for the DEXA (.6%) was significantly less than that in the Bod Pod (1.5%). Significant interactions between the body composition method and age group were found. Mean body fat percentage in the younger group was higher in the DEXA (24.1 + 1.1%) than the Bod Pod (23.0 + 1.3%) however, in the older group it was found to be lower in the DEXA (33.9 ± 1.1%) than the Bod Pod (37.2 ± 1.3%). Both the DEXA and the Bod Pod were reliable but repeated DEXA measures were more consistent than the Bod Pod measures. Bod Pod estimates of body fat percentage were lower for younger subjects, yet higher for older subjects compared to DEXA measurements. / School of Physical Education, Sport, and Exercise Science
