Spine degeneration can lower injury tolerance and influence injury outcomes in vehicle crashes. To date, limited information exists on the effect of age and gender on thoracic spine 3-dimensional geometry. The purpose of this study is to quantify thoracic spinal column and canal geometry using selected geometrical measurement from a large and continuous sample of CT scans. More than 33,488 scans were obtained from the International Center for Automotive Medicine database at the University of Michigan under Institutional Review Board approval (HUM00041441). The sample consisted of CT scans obtained from 31,537 adult and 1,951 pediatric patients between the ages of 0 to 99 years old. Each scan was processed semi-automatically using custom algorithms written in MATLAB (The Math Works, Natick, MA). Five geometrical measurements were collected including: 1) maximum spinal curvature depth (D), 2) T1-to-T12 vertical height (H), 3) Kyphosis Index (KI), 4) kyphosis angle, and 5) spinal canal radius. The data were analyzed by gender and age. Maximum spinal curvature depth occurred at T6, irrespective of age and gender. It continuously increased with age.…

Scientists Replace Metal Collimators with Plastic Analogs

Published 2020-01-01 by Tech Briefs Media Group in United States

Scientists have developed plastic collimators that can replace their metal analogs used in radiation therapy. The team focused on the exact characteristics of the desired product, its development, and testing. The study will be beneficial for both medicine and everyone who is interested in the effect of radiation on plastic products.

Using Simulation to Evaluate Laser Treatment Methods for Eye Tumors

Computational methods are not widely used in practical medicine, mainly because it is difficult to model specific medical procedures and their effects on the human organism and methods of treatment tend to be conservative. However, new methods to treat cancer using radiology and laser radiation are emerging at a rapid rate.

Quantitative Analysis of Raw Milk Using Spectral Sensors

Milk is one of the most widely used products, as well as being the raw material of all dairy products. Given this, measuring milk components has become very crucial for the dairy industry. Each dairy product requires milk with different ratios of its contents. Moreover, in order to keep track of the product quality, milk contents should be measured regularly.

Published 2019-04-02 by SAE International in United States
Crash safety researchers have an increased concern regarding the decreased thoracic deflection and the contributing injury causation factors among the elderly population. Sternum fractures are categorized as moderate severity injuries, but can have long term effects depending on the fragility and frailty of the occupant. Current research has provided detail on rib morphology, but very little information on sternum morphology, sternum fracture locations, and mechanisms of injury. The objective of this study is two-fold (1) quantify sternum morphology and (2) document sternum fracture locations using computed tomography (CT) scans and crash data. Thoracic CT scans from the University of Michigan Hospital database were used to measure thoracic depth, manubriosternal joint, sternum thickness and bone density. The sternum fracture locations and descriptions were extracted from 63 International Center for Automotive Medicine (ICAM) crash cases, of which 22 cases had corresponding CT scans. The University of Michigan Internal Review Board (HUM00043599 and HUM00041441) approved the use of crash cases and CT scan data.The sternum morphomics data showed the thoracic depth increased, except for the 60-74-year-old age group.…

Transparent Test Patch Determines Food Contamination

Published 2019-04-01 by Tech Briefs Media Group in United States

A transparent test patch, printed with harmless molecules, signals food contamination as it happens. The patch can be incorporated directly into food packaging, where it can monitor the contents for harmful pathogens such as E. coli and Salmonella. The new technology has the potential to replace the traditional “best before” or expiration date on food and drinks.

Chip Measures Quantities with Quantum Precision

Many devices use light to probe the quantum states of atoms in a vapor confined in a small cell. Atoms can be highly sensitive to external conditions, and therefore make superb detectors. Devices based on light interactions with atomic vapors can measure quantities such as time, length, and magnetic fields, and have applications in navigation, communications, medicine, and other fields. Such devices generally must be assembled by hand.

Fast, Flexible Ionic Transistors for Bioelectronic Devices

Many major advances in medicine, especially in neurology, have been sparked by recent advances in electronic systems that can acquire, process, and interact with biological substrates. These bioelectronic systems, which are increasingly used to understand dynamic living organisms and to treat human disease, require devices that can record body signals, process them, detect patterns, and deliver electrical or chemical stimulation to address problems.
