Anatomic Information

The aim of this study was to evaluate the use of Computed Tomography to study the anatomy of the eye and the vestibulocochlear organ of the wild birds. For this purpose, formaldehyde-embalmed specimens of a toucan and of a blue-and-yellow macaw were submitted to a whole-body scan by a 64 slice-Multidetector CT yielding 0,7mm-thick transversally oriented images. These were reconstructed by specific software that produced additional images in dorsal, transversal, and sagittal planes, as well as three-dimensional images, which were obtained by two techniques: Maximum Intensity Projection and Volume Rendering. Our study found that the eye bulbs in the orbit occupy a proportionally large space in the skull, highlighting the important role that vision plays in these animals. CT provided gross anatomic information about the size and shape of the eye, such as lenses and scleral rings of these birds. Regarding the vestibulocochlear organ, CT was less likely to identify the inner ear structures, especially the ones of the membranous labyrinth. The bony semicircular canals were clearly seen and in the middle ear, thecolumellawas identified. Our results demonstrate that the vestibulocochlear organ of birds is less complex than that of mammals, although, as expected, the semicircular canals are very well developed, being adapted to the accurate balance present in these animals.CT can be used as a good technique to evaluate eye and ear structures on these birds, and can be useful to study them in vivofor pathological conditions or for comparisons between different species.

Reconstruction Project

Facial reconstruction of mummies and corpses is important in anthropological, medical and forensic studies. The purpose of our study was to evaluate the role of three- Dimensional Multidetector CT examination for 3D facial reconstruction. We present a multidisciplinary work performed by radiologists, anthropologists and forensic police in reconstructing the possible physiognomy of an ancient Egyptian mummy. Three-Dimensional data were obtained from a well-preserved completely wrapped Egyptian mummy from the collection of the Egyptian Museum in Torino, Italy, dated from XXII or XXIII dynasty (945-715 BC). Data were used as a model for the rapid prototyping stereolithographic technique, a method which allows the creation of 3D model with digital data using synthetic materials such as resin or nylon.

This work investigates the effect of the contact surfaces on the biomechanical response of supine humans during whole-body vibration and shocks. Twelve participants were exposed to three-dimensional random vibration and shocks and were tested with two types of contact surfaces: (i) litter only, and (ii) litter with spinal board. The two configurations were tested with and without body straps to secure the supine human. The addition of the spinal board reduced the involuntary motion of the supine humans in most directions. There were significant reductions in the relative vertical accelerations at the neck and torso areas, especially during shocks ( p < 0.01). The inclusion of body straps with the spinal board was more effective in reducing the relative motion in most directions when shocks were presented. This study shows that the ergonomic design of the human transport system and the underlying contacting surfaces should be studied during dynamic transport environments.

Motion Capture Systems

Motion capture systems play an important role in health-care and sport-training systems. In particular, there exists a great demand on a mobile motion capture system that enables people to monitor their health condition and to practice sport postures anywhere at any time. The motion capture systems with infrared or vision cameras, however, require a special setting, which hinders their application to a mobile system. In this paper, a mobile three-dimensional motion capture system is developed based on inertial sensors and smart shoes. Sensor signals are measured and processed by a mobile computer; thus, the proposed system enables the analysis and diagnosis of postures during outdoor sports, as well as indoor activities. The measured signals are transformed into quaternion to avoid the Gimbal lock effect. In order to improve the precision of the proposed motion capture system in an open and outdoor space, a frequency-adaptive sensor fusion method and a kinematic model are utilized to construct the whole body motion in real-time. The reference point is continuously updated by smart shoes that measure the ground reaction forces.

Critical Intervention

Whole body contrast-enhanced multidetector CT (WB-CE MDCT) is integral to the assessment of the severely injured patient with stable haemodynamic parameters or in those who respond to resuscitation with blood products. WB-CE MDCT is able to identify the number and severity of injuries sustained by the patient and enable time critical intervention. In this narrative review article we discuss how communication within the trauma team, including the radiologists and appropriate clinicians is crucial in optimizing the effectiveness of WB-CE MDCT. We review the time critical imaging findings and their clinical relevance, which should be included in a succinct CT primary survey report. We also discuss the process through which the effectiveness of the trauma report may be maximised and how non technical factors including teamwork may be optimised to facilitate decision making in this high pressure environment.
