This fan beam collimator was designed to use with a multi-modality small animal imaging device and the performance of the collimator was studied for a 3D geometry.
Nevertheless, US correlates to some important limitations: the operator-dependent nature of the modality, low panoramicity due to small field of view and poor tissue characterization [1, 4].
Methods of classifying qualitative variables are dependent on the number of occurrences for each modality, and small counts make a minor contribution to the variance of the factorial axes [ 38].
We conclude that SWL is an effective and safe treatment modality for small renal stones and for upper ureteral calculi but not for cysteine stones.
Furthermore, this study shows that Cyberknife SBRT is a feasible, effective treatment for primary HCC, and suggests that Cyberknife SBRT be considered a promising noninvasive modality when small HCC of < 32 cc is inappropriate for surgical resection or ablation therapy.
Since ultrasonography is an inexpensive, non-invasive and effective modality, the small study supports the use of ultrasonography as a possible tool in the evaluation of volume status in patients with severe sepsis.
In this study, T score was evaluated using QUS, which has many advantages in assessing osteoporosis: the modality is small, no ionizing radiation is involved, measurements can be made quickly and easily, and the cost of the device is low compared with DXA and quantitative computed tomography devices.
A number of imaging modalities for small animals evolved over the last decade and were successfully applied in numerous studies [8].
The use of these imaging modalities in small laboratory animals allows a variety of experimental designs, which are not feasible in humans, and can help us to better understand the supraspinal control of the micturition cycle.
