Figure 5:Topographic images of beef primals Figure 6 shows examples of the slice images from the CT machine.They represent the density distribution across a single cross-sectional slice of a primal.Each scan will result in many hundreds of slice images which,when combined and processed,represent the full primal in 3D.

Figure 6:Slice images of beef primals 3.3 Second set of phantom and carcase scans at production X-Ray levels and reduced X-Ray levels. Initial analyses performed on the data obtained for the six beef sides evaluated through the dual-hardware DEXA setup indicated that the system demonstrates good potential for beef fat:lean ratio.During this analysis,a number of opportunity areas were also identified which may help to improve upon the result obtained.Thus,it was decided to perform another set of trials to gain a greater understanding of the behaviour of the system in the context of OCM and to achieve a higher level of confidence in the assessment of whether accurate OCM can be achieved with the system in its current configuration.

A second set of trials was designed to build upon this knowledge to further characterise the OCM capabilities of the Automated Beef Rib Cutter's x-ray system.This involved performing another set of phantom trials and scanning a further eight beef sides.The trial design was thus to: Take scans at production X-Ray settings as well as reduced current to allow visibility of 10mm tissue depths Rescan the phantoms at these lower energy levels and at different heights along the detector Scan another 8 sides-2 heavy,fat;2 light,fat;2 heavy,lean;2 light,lean Break down sides into primals,and scan with the CT scanner. ■■■ 量■■■ 包前 ■■组面夏 ■■■ 女国 ■■口 ■■■■ 则■■■ ■■■■ ■■■■ ■■■■■ 简 ■冒■复 ■图■日 度 Page 14 of 44

Figure 7:Scans of phantoms-colour image,high energy and low energy images at reduced X-Ray settings Once the phantom scans had been performed,eight sides were selected which were each scanned.As part of these trials,the following scanning protocol was used for each side: Phantom at reduced X-Ray settings Phantom at production X-Ray settings Carcase side at production X-Ray settings Carcase side at reduced X-Ray settings The carcase data for the sides selected for the trial is shown in Table 2.
