Radiation safety in pediatric interventional radiology: Step Lightly.
ABSTRACT The "Step Lightly" campaign, launched in 2009, is the next phase of the "Image Gently" social marketing campaign, and focuses on improving radiation safety during pediatric interventional radiology procedures. Downloadable content available on the Image Gently website includes parent-friendly information about radiation dose, protocol suggestions and procedure checklists for providers, and information for referring physicians, radiologic technologists and physicists. There are also links to additional reading material and to other relevant organizations.

ABSTRACT: An ultra-low-power-consumption high-gain low-noise amplifier for wireless applications operating in the 2.45 GHz industrial-scientific-medical (ISM) band has been developed. Under low dc power bias of 1.0 V and 0.96 mA, the amplifier demonstrated the state-of-the-art performance with a gain of 30.1 dB, NF of 4.31 dB, input and output return loss of less than -14 dB and the corresponding -1 dB compression point of -19.47 dBm at 2.45 GHz, achieving a gain/P<sub>dc</sub> figure of merit of 31.35 dB/mW and a gain/NF.P<sub>dc</sub> ratio of 7.27/mW, which are the highest ever reported at S-band.Microwave and Millimeter Wave Technology, 2002.

ABSTRACT: a b s t r a c t Purpose: Children are major users of imaging services but little is known about the provision made for them. The objectives of this survey were to: determine the extent to which children are imaged in primarily adult departments and the nature of procedures performed; establish the availability of child friendly environments and investigate the extent to which children are involved in service development. Methods: An 18 item questionnaire was sent to all hospitals with imaging facilities in the UK. Two versions were produced, one for adult departments and another for children's hospitals. Quantitative data were entered into SPSS-PC. Results: Three hundred and fifty two questionnaires were returned including 17 from the 20 children's hospitals, representing a 70% response rate. Children were imaged in 84% of adult hospitals from which responses were obtained and estimates provided by respondents indicated that more children were imaged in adult than children's hospitals. In 89% of adult hospitals responses indicated that infants were imaged and in two thirds of English hospitals advanced procedures, such as MRI, were available for children. In 47%, 32% and 30% of adult hospitals in England, Wales and Scotland children's requirements were said to be considered when purchasing equipment. In 34%, 11% and 8% of English, Welsh and Scottish adult hospitals some separate provision for children (for example waiting rooms or toilets) was indicated. Overall 32% of adult hospitals (92 of the 95 were in England) reported having a lead radiog-rapher, who specialised in a paediatric imaging. Responses indicated that in 60% of adult hospitals staff attended paediatric training courses. Children's views on hospital services were seldom sought in either the adult or children's hospitals. Conclusions: The survey indicates that the recommendations of the Children's National Service Frame-work and the Health Care Commission have not been implemented fully in many imaging departments.Radiography 02/2011; 17(1).
