A fuzzy inference system for two-phase flow regime identification from radiography images
Swiftly identifying the two-phase flow that occurs in coolant channels is crucial for monitoring energy producing installations such as boiling water reactors. In this piece of research, a Sugeno-type fuzzy inference system is implemented for online, non-invasive flow regime identification. The proposed system is predominantly efficient in its construction and operation: a single directly ...

AP and PA thorax radiographs: dose evaluation using the FAX phantom
Considering that the risks associated with ionising radiation are dependent on the characteristics of the exposed individual and that the structures and sizes of the human body vary considerably as a function of gender, efforts must be made in order to study the effective and absorbed doses in thoracic radiological examinations, taking into account the special features of the female anatomy. In ...

Medical Surveillance of Search Dogs Deployed to the World Trade Center and Pentagon: 2001–2006
In response to the terrorist attacks of September 11, 2001, at the World Trade Center and Pentagon, almost 50,000 rescue workers and approximately 300 search and rescue dogs participated in rescue and recovery operations. The dogs were exposed to the same hazards as the human workers, but did not have any of the personal protective gear. This prospective double cohort observational study compared ...

Dose and risk evaluation in thoracic radiology using male and female voxel phantoms
Thoracic radiology is of great concern because of its routine nature. It is important to avoid conditions where the amount of radiation used is more than that needed for the procedure. The purpose of this work is to use the Monte Carlo code MCNPX and the Female Adult voxel (FAX) and Male Adult voxel (MAX) phantoms to investigate how the effective doses, absorbed doses to organs and risk of cancer ...

Vidar Digitizers Support World Health Organization Childhood Pneumonia - Case Study
In many developing countries throughout the world, infant and child mortality rates are disturbingly high, and acute respiratory infections— in particular pneumonia—are a leading cause of death. As a result, preventing pneumonia is a priority, and the World Health Organization (WHO) and other healthcare institutions are studying a number of vaccines designed to protect against the ...

Relative effectiveness of Frameless stereotactic biopsy
Brain biopsy procedure has been evolving for the last four decades in concurrence with the imaging developments of the brain. Frame-based stereotactic interventions are considered the conventional gold reference standard for obtaining biopsy specimens of lesions from the brain. In this modality, a bulky head frame is fixed to the patient’s head before imaging procedures as it is an integral ...

The Use of High-Frequency Jet Ventilation in the Management of a Pre-term Infant with Pulmonary Stenosis and Respiratory Distress Syndrome. – A Case Report
The combination of congenital heart disease (CHD) and respiratory distress syndrome (RDS) can present a difficult scenario to manage with conventional mechanical ventilation (CMV). Our patient presented with poor right ventricular (RV) function, and refractory respiratory failure on CMV. High-frequency jet ventilation (HFJV) was used in order to improve ventilation at a similar or lower mean ...

How ML Will Disrupt the Future of Clinical Radiology
The use of computer vision in radiology may have advantages for both patients and medical facilities. However, some worry that machine learning (ML) may one day replace doctors because it can outperform them. The desire for increased efficiency and efficacy in clinical care has been the primary motivating reason behind the development of AI in medical imaging. Recent technological developments, ...

Dynamic Surgical Guidance to Facilitate Dental Implant Placement
The long-term success of dental implant surgery is dependent, in part, on accurate planning and placement of the implant.1 Currently, there are many digital planning systems available to aid the clinician in pre-operative treatment planning, although the main challenge with these planning systems is to accurately transfer the digital plan to the clinical situation. Most systems involve taking a ...
