Cím:Predictability of Egg Content in Hen's Eggs by Means of Cross Sectional Image Analysis / Tamás Donkó, Miklós Emri, Gábor Opposits, Gábor Milisits, Zoltán Sütő, Attila Orbán, Imre Repa
Megjegyzések:The present study was designed to determine the in vivo predictability of egg content in hen's eggs by means of computer tomography (CT). The experiment was carried out with altogether 120 eggs, which were originated from a 36 weeks old TETRA-H parent stock. During the CT measurements eggs were placed in egg holders (10 eggs) thus two eggs were scanned simultaneously. Following scanning parameters were set in: 110 kV ? 40 mAs, spiral mode, pitch 1, FoV 110 mm. In all cases eggs were scanned using overlapping 3 mm slice thickness on a Siemens Somatom Emotion 6 multislice CT scanner. On the CT images obtained the volume of the albumen, yolk and shell was determined by a self-developed egg-separation and segmentation software. After the CT measurements eggs were broken and their yolk, albumen and shell weight were measured. Between the CT predicted volumes and the measured weights Pearson correlations were calculated. The highest correlation (r=0.90) was found between the CT predicted albumen volume and the measured albumen weight. In the case of the yolk and shell the correlation coefficients were 0.793 and 0.713, respectively. Based on these results it was concluded that the accuracy of prediction seems to be precise enough in the case of the albumen, but its improvement is necessary in the case of the yolk and shell. Possible ways for improving the accuracy of prediction could be the use of another algorithm in the egg-segmentation software and the optimization of settings of the CT examination.
