The requirements are for five ultra-high specification cardiac ultrasounds to provide advanced paediatric echocardiography to scan Neonatal, Paediatric and Adolescent patients. The system must be capable of custom configuration and incorporate the latest advancements in 2D, 3D, 4D imaging, probe technologies, and AI enabled functionality. It should be built on a modern scalable platform that supports future upgrades and represents the most current technologies available from manufacturers. These systems are essential to ensure efficient, safe and comfortable ultrasound imaging for paediatric patients. The system must support Neonatal, Paediatric and Adolescent studies on a single platform. Particular emphasis is on suitability for National Children’s Hospital(NCHI) requirements. Tenderers should note that the hospital is a paediatric facility with patients ranging from neonatate to adolescent (i.e adults), so the system must incorporate full adult imaging capabilities. NCHI serves as the national tertiary and quaternary referral centre for paediatric patients and also provides primary and secondary care for the greater Dublin area. State of the art equipment is required to meet the demands of a high-volume cardiology ultrasound imaging service. The system must be suitable for use across multiple clinical environments, including: Cardiac Outpatient Department Cardiac Intensive Care Unit Cardiac Catheterisation Theatres, Cardiac Hybrid Imaging Theatres Open Heart Surgery Theatres. Mobile bedside imaging should patients be unable to attend cardiac inpatient clinics. It is imperative that all equipment is highly reliable, supports efficient clinical workflows, and operates consistently to minimise risks to patients and staff The system must deliver high quality imaging that ensures heart structures are quickly and easily identified and provide precise quantitative data. It must also seamlessly integrate with PACS Systems ensuring that imaging data is efficiently transferred and readily accessible. This will support clinicians in determining optimal treatment pathways and monitor patient progress in a safe, efficient and child friendly environment. The appendices set out the requirements for the system and invites the market to respond with a suitable configuration to meet these needs.
