Finding why an MRI suite loses exams
A digital twin demo for a hospital MRI suite: the day's exams against the schedule, the scanner's cooling water and the hospital's chilled water, with an advisor that follows a lost exam back to its cause. The suite, the schedule and the data are simulated.
What's on the screen
- The 3D suite. The scan room (the scanner and its table), the control room, the equipment room (cabinets, the cooling cabinet, the helium compressor) and the hospital's chilled-water plant. The cooling view colours the water in every pipe by its temperature and shows the scanner's gradient coil.
- Today's exams. 24 appointments and how long each exam actually took; the exam on the table, the delay, the afternoon's average exam length and the end-of-day forecast.
- MRI cooling. The scanner's cooling water, its gradient coil, the building's chilled water, the chiller's load and the helium compressor's water, each against its limit.
- The advisor. It matches the longer exams with the data that changed in the same period. Here, on a hot afternoon, the hospital's chillers run at full load; the chilled water arrives at around 14 °C instead of 7 °C, the scanner's cooling water goes over its 22 °C limit, and before each heavy sequence the scanner waits for its gradient coils to cool. Exams run long, the schedule slips and the day ends 2 exams short. The advisor gives the cause, the risk and what to do, together.
How to try it
- Use the camera buttons to move from the whole suite to the scan room, the equipment room and the chiller, or drag to orbit.
- Scrub through the day in the bar below. In the morning exams run on schedule; in the afternoon the cooling waits begin and the schedule slips. The advisor gives its finding at 14:45.
- "Cooling view" colours the pipes by water temperature. "Show in the suite" on the advisor card follows the chilled water from the chiller to the scanner.
- "Watch the film" plays the same scene full screen as a 26-second walkthrough.
In a real installation
This page is a demo: the suite, the schedule and the data are simulated and representative; it does not show a system installed in a hospital. In a real installation, exam times come from the RIS or the scanner's logs, cooling-water and compressor data from the scanner's service interface or added sensors, and chilled-water and chiller data from the building management system. The advisor's rules are set up for that suite's and that building's limits.
