1Computed tomography and patient risk:Facts,perceptions and uncertainties显示文摘Since its introduction in the 1970s, computed tomography(CT) has revolutionized diagnostic decision-making. One of the major concerns associated with the widespread use of CT is the associated increased radiation exposure incurred by patients. The link between ionizing radiation and the subsequent development of neoplasia has been largely based on extrapolating data from studies of survivors of the atomic bombs dropped in Japan in 1945 and on assessments of the increased relative risk of neoplasia in those occupationally exposed to radiation within the nuclear industry. However, the association between exposure to low-dose radiation from diagnostic imaging examinations and oncogenesis remains unclear. With improved technology, significant advances have already been achieved with regards to radiation dose reduction. There are several dose optimization strategies available that may be readily employed including omitting unnecessary images at the ends of acquired series, minimizing the number of phases acquired, and the use of automated exposure control as opposed to fixed tube current techniques. In addition, new image reconstruction techniques that reduce radiation dose have been developed in recent years with promising results. These techniques use iterative reconstruction algorithms to attain diagnostic quality images with reduced image noise at lower radiation doses.Stephen P Power Fiachra Moloney Maria Twomey Karl James Owen J O'Connor Michael M Maher 2016World Journal of Radiology2016,8,12:7

15User-centered development and performance assessment of a modular full-body exoskeleton (AXO-SUIT)显示文摘This paper presents the design and preliminary performance assessment of a full-body assistive exoskeleton(AXO-SUIT)for older adults.AXO-SUIT is a system that consists of separate lower-body and upper-body modular exoskeletons,which can be combined to form a full-body system to provide flexible physical assistance as needed.The full-body exoskeleton comprises 27 degrees of freedom(dof),of which 17 are passive and 10 active.It can assist people in walking,standing,carrying and handling tasks.A user-centered design approach was adopted throughout the development of the exoskeleton.This paper describes the design process of AXOSUIT,involving a review of user needs,a kinematic and kinetic motion study,and innovative system design.Tests with the developed systems were conducted on selected end-user subjects,covering both performance evaluations at different levels and useability testing.End-user testing results show the effectiveness of the exoskeleton in providing flexible physical assistance.Shaoping Bai M.R.Islam Valerie Power Leonard OŚullivan 2022Biomimetic Intelligence & Robotics2022,2,2:1
