Romanian medical exposure to ionising radiation in 2012
Medical exposure, the main source of artificial exposure, shows an increasing trend in the last years, manifested both by increasing the number of examinations with ionising radiation and by increasing the patient dose level. Annual results obtained for medical exposure to ionising radiation based on the data collected from Romanian hospitals are useful for the update of the national database and optimisation of diagnostic procedures in radiology and nuclear medicine. Medical exposure level is expressed in terms of annual collective dose and is evaluated from annual frequencies and the average effective dose per procedure ...

Examination frequency and population dose from medical X-ray examinations in Sudan in 2010
This study was performed to estimate examination frequency and collective and per caput effective doses arising from medical X-ray procedures in Sudan, 2010. Information was collected from 30 hospitals performing radiography, computed tomography (CT), fluoroscopy and interventional radiology (IR) procedures. The estimated annual number of examinations was 33 million radiographic X-ray procedures (99 %), 0.34 million CT exams per year (14 % paediatrics CT), 0.02 million fluoroscopy and IR procedures. The estimated annual number of examinations was 326 per 1000 people. The estimated annual collective and per caput effective ...

Localized Energy-Based Normalization of Medical Images: Application to Chest Radiography
Automated quantitative analysis systems for medical images often lack the capability to successfully process images from multiple sources. Normalization of such images prior to further analysis is a possible solution to this limitation. This work presents a general method to normalize medical images and thoroughly investigates its effectiveness for chest radiography (CXR). The method starts with an energy decomposition of the image in different bands. Next, each band's localized energy is scaled to a reference value and the image is reconstructed. We investigate iterative and local application of this technique. The normal...

Providence Medical touts 2-year cervical fusion data, $2.9m funding round
Cervical spine-focused Providence Medical last week released 2-year radiographic and clinical outcomes from a study of its DTrax system of instruments and implants and announced a $2.8 million round of equity financing.
Results from the single-arm, multi-center study were presented at the Spine Week 2016 conference in Singapore last week, the Walnut Creek, Calif.-based company said.
“The 2-year results of this study are promising and suggest DTrax technology is a valuable addition to the armamentarium of options for surgeons treating patients with cervical radiculopathy,” Dr. Kris Siemionow of Chicago’s...

Development of a universal medical X-ray imaging phantom prototype.
Abstract
Diagnostic X-ray imaging depends on the maintenance of image quality that allows for proper diagnosis of medical conditions. Maintenance of image quality requires quality assurance programs on the various X-ray modalities, which consist of pro-jection radiography (including mobile X-ray units), fluoroscopy, mammography, and computed tomography (CT) scanning. Currently a variety of modality-specific phantoms are used to perform quality assurance (QA) tests. These phantoms are not only expensive, but suitably trained personnel are needed to successfully use them and interpret the results. The question arose...

Effective doses and standardised risk factors from paediatric diagnostic medical radiation exposures: Information for radiation risk communication
ConclusionStandardised risk factors for different radiological and nuclear medicine examinations and an overview of the deleterious effects of ionising radiation and the difficulties encountered in communicating the risks should facilitate risk communication to the patient/carer.

Improved Identification of Venous Thromboembolism From Electronic Medical Records Using a Novel Information Extraction Software Platform
Introduction:
The United States federally mandated reporting of venous thromboembolism (VTE), defined by Agency for Healthcare Research & Quality Patient Safety Indicator 12 (AHRQ PSI-12), is based on administrative data, the accuracy of which has not been consistently demonstrated. We used IDEAL-X, a novel information extraction software system, to identify VTE from electronic medical records and evaluated its accuracy.
Methods:
Medical records for 13,248 patients admitted to an orthopedic specialty hospital from 2009 to 2014 were reviewed. Patient encounters were defined as a hospital admission where both surgery (o...

Medical physics 3.0 versus 1.0: A case study in digital radiography quality control.
CONCLUSIONS: MP1.0 tests failed to detect substandard system performance, but MP3.0 methods determined the root cause of the problem. MP3.0 exploits the wealth of data with more sensitive performance indicators. Data analytics are powerful tools whose proper application could facilitate early intervention in degraded system performance.

Strategies for Inclusive Medical Imaging Environments for Sexual and Gender Minority Patients and Radiographers: An Integrative Literature Review
Sexual and gender minority patients, and radiographers, experience several challenges that hinder realisation of their rights to equality and to a standard of living which is adequate for their well-being and health, in clinical environments. To this extent, a person-centred care approach is advocated for the medical radiation science professions so that a more inclusive medical imaging environment for patients and radiographers is provided. There is no summation of the body of knowledge available to promote all-encompassing environments for sexual and gender minority groups in medical imaging.

Burnout in the disciplines of medical radiation science: A systematic review
Burnout is seen as an occupational phenomenon related to workplace stress. Professional groups within medical imaging and radiation science have been reported to suffer from burnout in the past, however research into the profession has been limited. This systematic review aims to evaluate literature measuring levels and prevalence of burnout in the professional groups within medical imaging and radiation science (MIRS). These being radiographers (radiological technologists), sonographers, radiation therapists (therapeutic radiographers) and nuclear medicine technologists.

The Application Artificial Intelligence (AI) in Radiation Protection and Medical Imaging: How prepared are Radiographers?
The medical imaging world is currently changing with the introduction of advanced modalities to help with diagnosis and therapeutic procedures. AI is increasingly being integrated in radiation medicine. As new AI tools are developed it is essential that robust validation is undertaken in compliance with evidence based medical imaging. There is then the need for the application of Artificial Intelligence (AI) in areas such as radiation protection in medicine to improve the safety of patient's personnel and the public.

5 Diagnostic radiography and reach back capability in the remotely deployed environment; a summary from op newcombe rotation 3
Diagnostics remains to be an important and vital capability of any deployed field hospital or surgical team, particularly for teams that find themselves deployed in the most remote locations, such as Mali. The DRGo gives the British military a portable radiography solution. Completely digital, it provides an instantaneous X-ray for clinicians to review. A 6-month period between Dec 21 and Jun 22 saw 29 full X-ray examinations completed with a 50% split between those patients being referred for imaging in the firm base and those referred whilst out on patrol. With no deployed radiologists on the ground, the ability to obtai...
