Trans-skull Ultrasound for Imaging and Therapy
… for imaging. Despite these advancements, the skull remains a major challenge both for therapy and imaging. This work proposes methods for fast, frequency-selective passive reconstruction of the acoustic field through human skull with applications including improved targeting for exploitation …

A Study of Measuring Intracranial Pressure Using a Non-Invasive Piezoelectric Sensor
The brain, like many parts of the human body, can experience swelling, also known as cerebral edema. Cerebral edema may occur because of an injury, health related issues, tumors, or even high altitudes[1]. When cerebral edema occurs, a rise in intracranial pressure (ICP) becomes prevalent and may …

A Preliminary Investigation Comparing Craniofacial Metric Measurements and 3D Virtual Measurements
… can be quantitatively assessed for use on the human skull. I used a Polhemus Fast Scan Scorpion scanner to scan 8 skulls and evaluated the standard 24 metric measurements in Delta analysis software in comparison to standard metric measurements. The scanned measurements were then compared to the …

The Development and Implementation of An Anthropomorphic Head Phantom For The Assessment of Proton Therapy Treatment Procedures
… measured for potential phantom materials and a human skull was cast in tissue-equivalent Alderson material (RLSP 1.00, HU 16) with anatomical airways and a cylindrical hole for imaging and dosimetry inserts drilled into the phantom material. Two treatment plans, proton passive scattering and …

Epigenetic Traits, Computerized Tomography And Native American Identity
… variations in trait expressions found on the human skull, and largely disregarded. It is now known many of these traits are heritable and potentially define population affinity. Native American skeletal collections have been diminishing after the 1990 Native American Graves Protection and …

Big Brains and Small Teeth: a primate comparative approach to dental and mandibular reduction in hominins
… apparatus. In the Holocene, the changes in human lifestyle triggered by agriculture would have determined the reduction in human tooth size. Brain expansion may have acted as a constraint on the development of the lower jaw. In this work, a primate perspective was adopted to clarify the …

Development of a statistical shape and appearance model of the skull from a South African population
… can make use of SSMs and SAMs of the skull. A combination of the SSM and SAM of the skull can also be used in model-based segmentation. This document presents the development of a SSM and a SAM of the human skull from a South African population, using the Scalismo software package. The …

Development of A Ct Metal Artifact Management Algorithm For Proton Therapy Planning (Ampp) For Head and Neck Cancer Patients
… composed of proton tissue equivalent materials, human skull, air cavities was used to perform a quantitative image quality comparison between AMPP and four major CT vendors’ commercial metal artifact reduction (MAR) solutions (OMAR from Philips, iMAR from Siemens, SEMAR from Canon, SmartMAR from …

Shock wave interaction with a fluid filled cylinder experimental methods
… question. Polycarbonate is chosen to simulate human skull. De-ionized water is used as the fluid as its mechanical property is close to that of brain. As the human head varies in thickness from 4mm in the temporal region to 8mm in the occipital region of the skull, two different thickness …

Objects and anxiety in late medieval English writing
… stone idols and invisible flowers, clothing, and skull cups--I argue that each object provides a spectrum of possible readings for users, who simultaneously interpreted objects as essential to a spiritual and communal existence, while also fearing that goods might inhibit the soul's relationship …

miR-125b toggles dynamics and structure of dendritic filopodia in developing hippocampal neurons
… had to achieve all this in the space of a single human skull. This is the self-organization challenge of the axons and dendrites of the brain. Developing dendrites encounter a variety of stimuli that direct their growth and final architecture. Cellular substrates respond to these stimuli, …

Treatment of brain cancer and ischaemic stroke utilising High Intensity Focus Ultrasound (HIFU) guide with MRI
… 0.5 MHz and pulsing to optimize thrombolysis and skull penetration and at the same time avoiding unwanted heating. Finally, an Acrylonitrile Butadiene Styrene (ABS) phantom skull model was developed in order to evaluate the propagation of ultrasound using a single element transducer. The skull …

An investigation of the biomechanical response from shock wave loading to the head
… primary brain injury due to blast: multimodal skull flexure. The significance of this research is twofold. First, resolution of the mode of energy transfer and of the induced stresses within the skull-brain system will allow for creations of mitigation/protective techniques/equipment, as well …

A view of colonial life in South Australia: An osteological investigation of the health status among 19th-century migrant settlers
Studies of human skeletal remains contribute to understanding the extent to which conditions prevailing in various past communities were detrimental to health. Few of these studies have evaluated the situation in which the first European colonists of South Australia lived. Colonial Australian …
