The aim of this study was to determine the morphometric values of the skull and the mandible of the common opossum from the Caribbean island of Trinidad and Tobago. The skulls and mandibles were obtained from ten opossums captured for research purposes. The skulls and mandibles were prepared and cleaned using standard method. Some anatomical landmarks of the skulls and mandibles were identified...

The sensorimotor system of the human brain and body is fundamental only in its central role in our daily lives. On further examination, it is a system with intricate and complex anatomical, physiological, and functional relationships. Sensorimotor areas including primary sensorimotor, premotor, supplementary motor, and higher order somatosensory cortices are critical for function and can be loc...

Accuracy of surgical navigation depends on the registration process. The most common registration method has been the point based registration. In point-based registration between the patient and the image, skin markers are often used. Although registration accuracy appears relatively high in the region around the markers, the accuracy is not sustained at a deeply seated target in the body. To ...

REASONS FOR PERFORMING STUDY The distal limb innervation of the horse has been studied extensively to allow use of local anaesthetic techniques to detect the origin of pain in lameness. However, the innervation of the lumbar spine has so far been poorly described and a more precise description may assist clinicians to localise back pain in the horse. OBJECTIVES To gain better knowledge of the...

We describe 3D operators for extracting anatomical landmarks which are based on only first-order partial derivatives of an image. To improve the predictability of the extraction results we analyze certain properties of the operators. First, we provide a statistical interpretation in terms of the Cramér—Rao bound representing the minimal localization uncertainty. Second, we show that the operato...

In this paper we analyze the performance of a pipeline for the extraction and semantic labelling of geometrically salient points on acquired human body models, improving the quality of the results and discussing its robustness against pose and body type variations. Following the approach introduced in [10], we use a heat diffusion approach automatically detecting points as maxima of the autodif...

The buccal space is an anatomical compartment lying anterior to the masticator space and lateral to the buccinator muscle. Since the major purpose of imaging is to define the likely anatomic origin and also the extent of a given lesion, thorough knowledge of the normal anatomy of the buccal space is essential, and this knowledge can aid the physician in narrowing down the list of possible malad...
