Hematologic characteristics of the woylie (Bettongia penicillata ogilbyi).

An accurate assessment of animal health is fundamental to disease investigation in wildlife. Blood samples (n = 609) from several populations of the endangered woylie or brush-tailed bettong (Bettongia penicillata ogilbyi), collected between March 2006 and April 2010 in Western Australia and South Australia, were used to establish hematologic reference ranges. Differences between populations, sexes, and seasons were also investigated.

Effect of number of projections on image quality of local CT.

Objectives: To determine the image quality of the local CT imaging procedure, in terms of resolution, contrast, and noise as a function of the number of projections.

Methods: The contrast and resolution of the images was determined with a phantom object consisting of three rods of different materials, as well as a phantom human head embedded in soft tissue equivalent material. In addition, slices reconstructed from computed sinograms were used for comparison.
