  6. 6. The Hessing Foundation - implementing an integratedsuccess story QA solution for diagnostic, monitoring and reporting Implementing an Implementing an integrated QA integrated QA solution solution for diagnostic, monitoring for diagnostic, monitoring and reporting and reporting The role that a reliable screen representation plays in diagnosis and reporting is clear to every radiologist. In practice, however, quality control and proper monitor set-up are often neglected. Not by the Hessing Foundation. The renowned healthcare provider relies on an integrated system from NEC Display Solutions. The Hessing oundation belongs to the leading orthopaedic clinics in Germany. Over past decades various specialised clinics and specialist centres have developed from the former orthopaedic sanatorium in Augsburg-Göggingen. Due to the broad service that the Hessing foundation combines under one roof today, patients receive the best all round care. The challenge Of course the accuracy of the diagnosis plays a central role in the clinic. The hospital management knows what significance the correct DICOM-compliant depiction of the CT and the X-Ray images has on the diagnostic monitors. An inaccurate representation can have fatal consequences in this area. Therefore a complete integrated solution was sought where the calibration of the monitors runs largely automatically. After an extensive evaluation of diagnostic screens from various manufacturers, the Hessing Foundation chose NEC. 06_Wedgwood AV Ltd - 01754 769967

The answers given are logged in the process, and when collected can also be handed over on request to the medical authorities. The result The implementation of the complete system was concluded in November 2010 and also included the prescribed acceptance testing of the monitors, with entry of the data and reference values for the consistency checks into the QAXRAY system. “Meanwhile we have operated QAXRAY for six months and performed consistency testing. In addition to halving the test time per screen compared to the previous method, the central archiving of the test reports is a critical advantage.

  10. 10. IP54 rated touchscreensTOUCHSCREENS for healthcare iiyama have a range of touchscreens for use in teaching classrooms, digital signage applications, and IP54 rated models with edge to edge glass front for easy cleaning, for use on the wards and in public areas. Their range includes touchscreens from 15” to 32” diagonal, perfectly suited for a variety of medical applications. iiyama range of touchscreens include models with capacitive touch technology which means a sensor-grid of micro-fine wires are integrated into the glass that covers the screen. Touch is detected because electrical characteristics of the sensor grid change when a human finger is placed on the glass. Other models such as the T2451MTS, use optical sensing technology which uses cameras, ideal for drag and drop applications. Touchscreens with IP54 rating make it dust and water resistant. iiyama ProLite T2234MC with IP54 rating, use landscape or portrait The iiyama ProLite T2234MC uses capacitive touch technology, built into a bezel with edge-to-edge glass. Featuring IPS LCD screen technology, it has wide viewing angels, making it ideal for digital signage. This model is IP54 rated, making it dust and water resistant. The glass overlay is highly durable and the touch function remains unaffected even if the glass is scratched. It works with human finger touch whether gloved or not. The multi-touch functionality is supported under Windows® 7/8 only. The iiyama ProLite T3234MSC 32-inch screen is full HD (high definition) with 1920x1080p resolution which means you can accommodate more information on the screen, e.g. 60% more in comparison to a 1280x1024 monitor. This model is not IP54 rated, and can be used for interactive digital signage, for example, in university teaching hospitals. 10_Wedgwood AV Ltd - 01754 769967
  11. 11. LS2S have developed a kiosk for use in healthcare applications for capturing patient feedback. The kiosk features three iiyama screens (T2451MTS - 24” widescreen TOUCHSCREENS multitouch LCD using optical sensing technology). This solution is being used in A&E at Hinchingbrooke Hospital. On a tiered system of three screens (top - signage, middle for standing access, bottom for wheelchair access), the public are able to book themselves in and add details etc. on their reasons for the visit. It is designed so that both the middle and bottom touchscreens can be used for the same questionnaire, and the user can chose which screen suits them best, depending on their height and whether they need to be seated (e g wheelchair users). The top screen is used to display static or dynamic branding and / or information about the survey. The kiosk meets accessibility guidlines for wheelchair users. The angles of the two lower input screens are carefully set to maximise patient privacy. The kiosk is fully compliant with NHS information governance and Connecting for Health requirements. Patient surveys are quickly and easily configured using L2S2’s kiosk framework and the results displayed using L2S2’s visualisation framework that includes dashboards. The kiosk has been developed to meet NHS requirements for connection to the internal (N3) NHS network.If you’d like to have a demonstrationof the iiyama range of screensincluding the IP54 rated screens, atyour hospital or medical practice inthe UK, then please contact us.Tel: 01754 769967sales@wedgwood-group.com• 01754 769967• sales@wedgwood-group.com• www.wedgwood-group.com www.teachingtechnology.co.uk_11

  20. 20. MOUNTS FOR MEDICAL ErgoMounts Professional grade medical mounting solutions ErgoMounts, Medical division focuses on manufacturing and distributing high quality mounting solutions for LCD monitors, CPUs and keyboards. ErgoMounts medical portfolio is widely used in both medical and non medical environments. The high quality finish of all solutions allow alcohol wipes to be used to clean all surface areas without causing surface deterioration. ErgoMounts have been suppliers to a number of NHS trusts and also offer ongoing maintenance using the Planned Preventative Maintenance Programme (PPM). The New Frome community hospital was built to replace the old Frome Victoria hospital. Patients are admitted from district general hospitals and from home and receive their medical care from their GP practice. The new Frome hospital required full installation of Patient TV equipment to the newly refurbished wards. From the outset clinical staff wanted to minimise wall mounted items and therefore identified ceiling mounts as the solution. The T2 Elite series of ceiling mounted hospital LCD TV/monitor mounting solutions is designed for ease of use by both patients and clinicians alike. Each T2 Elite ceiling mount provides 360° of screen swivel and 90° downward tilt. This enables patients to view TV whilst sitting or lying in the bed and also whilst seated in an adjacent chair. As a fully cable managed monitor mounting solution, the arm is ideal in hospital and dental environments. Designed to meet modern healthcare infection control standards and to be cleaned with hospital grade / chlorine based cleaning solutions, making them ideal for use in clinical areas including operating theatres, recovery, dental and wards. ErgoMounts worked closely with the architect and main contractor and carried out a full site survey and assessment of the new wards and it was agreed that the T2 Elite series would both benefit and exceed all the criteria. ErgoMounts professional installation service was untilised to ensure full installation of the 28 solutions and an ongoing maintenance contract was agreed. 20_Wedgwood AV Ltd - 01754 769967
