A gamma camera count rate saturation correction method for whole-body planar imaging.

Whole-body (WB) planar imaging has long been one of the staple methods of dosimetry, and its quantification has been formalized by the MIRD Committee in pamphlet no 16. One of the issues not specifically addressed in the formalism occurs when the count rates reaching the detector are sufficiently high to result in camera count saturation. Camera dead-time effects have been extensively studied, but all of the developed correction methods assume static acquisitions. However, during WB planar (sweep) imaging, a variable amount of imaged activity exists in the detector's field of view as a function of time and therefore the camera saturation is time dependent. A new time-dependent algorithm was developed to correct for dead-time effects during WB planar acquisitions that accounts for relative motion between detector heads and imaged object. Static camera dead-time parameters were acquired by imaging decaying activity in a phantom and obtaining a saturation curve. Using these parameters, an iterative algorithm akin to Newton's method was developed, which takes into account the variable count rate seen by the detector as a function of time. The algorithm was tested on simulated data as well as on a whole-body scan of high activity Samarium-153 in an ellipsoid phantom. A complete set of parameters from unsaturated phantom data necessary for count rate to activity conversion was also obtained, including build-up and attenuation coefficients, in order to convert corrected count rate values to activity. The algorithm proved successful in accounting for motion- and time-dependent saturation effects in both the simulated and measured data and converged to any desired degree of precision. The clearance half-life calculated from the ellipsoid phantom data was calculated to be 45.1 h after dead-time correction and 51.4 h with no correction; the physical decay half-life of Samarium-153 is 46.3 h. Accurate WB planar dosimetry of high activities relies on successfully compensating for camera saturation which takes into account the variable activity in the field of view, i.e. time-dependent dead-time effects. The algorithm presented here accomplishes this task.

The Nursing and Midwifery Resource - Towards Workforce Planning

The Nursing and Midwifery Resource – Towards Workforce Planning The past five years have seen a dramatic change in the composition and organisation of the nursing and midwifery workforce in Ireland. For many years we had a constant supply of newly qualified nurses and midwives, with strong competition for every available post. Click here to download PDF 1.5mb

Planning Health and Social Care Services for the Elderly

The Department of Health’s strategy, Shaping a Healthier Future – A Strategy for Effective Healthcare in the 1990s stated that “to provide the firmest possible basis for the planning of services in the longer-term, the Department of Health will commission a study on the implications for the health services of the projected increase in the elderly population over the next ten years Download the Report here

Planning for Dementia Care in Ireland: Conference Proceedings

The Conference, which took place on 4th June 1999 in the Royal Marine Hotel, Dun Laoghaire, marked the publication of the Councilâ?Ts latest report â?" An Action Plan for Dementia.  The Action Plan takes as its guiding principle the recognition of the individuality of the person with dementia and of his or her needs. It outlines an approach to developing available, accessible and high quality services in the context of existing resources and public expenditure constraints. Its aim is to describe a best practice model of dementia care in Ireland â?" a model which may inform and guide policy makers and others involved in planning service provision, and which may give support and assistance to those who endeavour to provide flexible services at the local level.

Comparison of fundus autofluorescence images acquired by the confocal scanning laser ophthalmoscope (488 nm excitation) and the modified Topcon fundus camera (580 nm excitation).

To compare autofluorescence (AF) images obtained with the confocal scanning laser ophthalmoscope (using the Heidelberg retina angiograph; HRA) and the modified Topcon fundus camera, in a routine clinical setting. A prospective comparative study conducted at the Jules-Gonin Eye Hospital. Fifty-six patients from the medical retina clinic. All patients had complete ophthalmic slit-lamp and fundus examinations, colour and red-free fundus photography, AF imaging with both instruments, and fluorescein angiography. Cataract and fixation were graded clinically. AF patterns were analyzed for healthy and pathological features. Differences of image noise were analyzed by cataract grading and fixation. A total of 105 eyes were included. AF patterns discovered by the retina angiograph and the fundus camera images, respectively, were a dark optic disc in 72 % versus 15 %, a dark fovea in 92 % versus 4 %, sub- and intraretinal fluid visible as hyperautofluorescence on HRA images only, lipid exudates visible as hypoautofluorescence on HRA images only. The same autofluorescent pattern was found on both images for geographic atrophy, retinal pigment changes, drusen and haemorrhage. Image noise was significantly associated with the degree of cataract and/or poor fixation, favouring the fundus camera. Images acquired by the fundus camera before and after fluorescein angiography were identical. Fundus AF images differ according to the technical differences of the instruments used. Knowledge of these differences is important not only for correctly interpreting images, but also for selecting the most appropriate instrument for the clinical situation.

Planning Practice Guidance

The Department for Communities and Local Government has published National Planning Practice Guidance which recognises the importance of local infrastructure planning in the development of healthy communities. The guidance supports the National Planning Policy Framework and now includes a section on health and wellbeing. This guidance sets out the government’s planning policies for England and how these are expected to be applied by local authorities. A significant development in the guidance is the recognition of the important role the planning system can play in facilitating social interaction and creating healthy, inclusive communities. Local planning authorities should ensure that health and wellbeing, and health infrastructure are considered in local and neighbourhood plans and in planning decision making.

An Integrated Work Force Planning Strategy For The Health Services 2009 - 2012

Workforce planning identifies the composition of the workforce required to deliver health service goals. It encompasses a range of human resource activities aimed at the short, medium and long-term. Workforce planning that is integrated with service and financial planning offers the best opportunity for linking human resource decisions to the strategic goals for the health services. Systems and structures are required to support and develop workforce planning activities
