The Utilization dashboard contains various information panels. The types of panels differ depending on the medical IoT device category filter you select.

Trend – The Trend information panel displays graphs that help you spot trends in the way your devices are being used.

For medical imaging devices, the Trend panel shows two graphs. The line graph shows the number of images taken at intervals throughout the period set as the time filter. The bar graph shows the total case studies created during the same period. At a glance, you can see patterns of activity and any periods of lulls and spikes. Hovering your cursor over a data point shows the number of images and case studies at that point. If you only want to see one chart or the other, click Images or Case Studies in the upper right corner of the Trend panel to show or hide them. If you want to focus attention on one graph but not completely hide the other, hover your cursor over Images or Case Studies to cause the other one to fade.

For infusion systems, the Trend panel displays a line graph to track the number of systems in use and the number connected to the network (online) but not necessarily in use. If all connected infusion systems were both connected and in use, the two lines appear to be a single line because all their data points align. However, if you hover your cursor over Devices Used or Devices Online Only in the upper right corner of the Trend panel, you can show or hide one line or the other. Hover your cursor over a data point to see the number of devices that were used and those that were connected at that point.

The number that appears to the left of the chart is not an overall total. It shows how many infusion systems were used today, using the most recent time for which a total can be calculated.

Imaging Scan Analysis – This panel summarizes the sections of the human body that were scanned by imaging devices. It is shown for all DICOM devices except ultrasound equipment, which doesn’t identify scanned body parts in its traffic.

The panel is divided into two sections. On the left is a human figure consisting of four major anatomical regions:

The coloring of each body region represents the volume of scans performed on it. The darker a section is the more scans were done there.

On the right are five bar charts, one for each of the four major anatomical regions and a fifth for the Other grouping. Chunking the data in this way makes it easier to see how your imaging equipment is being used. The bars in each chart represent the number of scans for more specific body areas (for example, a bar for the more specific Mouth and Throat is within the bar chart for Head and Neck). The charts include bars for areas where the most scans were performed. To see a full list, hover your cursor over one of the main sections and a popup appears.

Devices – This information panel shows the total number of devices on the network in the past year and how many devices were connected to the network and used, connected but not used (online only), and disconnected (offline) during the filtered time range.

Click a section of the donut graph or a tab heading to switch lists. Click View all <number> devices to open the Devices page with a filter set to show only the devices in the active list. Click a specific device name to view device details for it.

When you click an entry in the Device Name column, the Device Details page for it opens. While viewing the Device Details page, click Utilization to see more detailed information.

The Utilization section on the Device Details page for any imaging device such as an ultrasound machine, X-ray machine, or CT scanner, shows when that device is and is not being used, how it's being used, and when it communicated with the device vendor. For example, with the time filter set to 1 Month at the top of the Device Details page, the Device Usage by Hours information panel shows the times when the device was in use during the past month.

The legend in the upper right explains how the colors indicate how much the device was used at each hour. The darker the green, the more it was used. You can also hover your cursor over a square to see a tooltip explaining how often the device was used at that time. For example, in the image shown above, the device was used three times on Wednesday during the 2:00 PM hour.

In Device Usage by Number, you can see the number of images the device took–or, by clicking Case, the number of cases for which the device took images. In Vendor Activities, you can see when the device communicated with its vendor, which for many devices is an automated means for obtaining software and security updates. You can see the traffic that the vendor initiated and total vendor traffic, which is a superset of all communication between the device and the vendor regardless of which one initiated it.

When viewing the Utilization section on the Device Details page for an infusion system, the IoT Security portal displays the following information.

The blue bars in the upper graph, show how long the device was in use. For 1 week, 1 day, or 2 hours, each blue bar indicates the number of minutes per hour (60 minutes maximum) that the device was in use over the past 168, 24, or 2 hours. For 1 month or 1 year, it shows the number of minutes per day (1440 minutes maximum) that the device was in use every day for the past 30 or 365 days.

The lower graph shows how this device compares with others in the same device category. You can see how long it was in use and the percent of time it was actively used in relation to the time range set. In the example above, it was used for 9.72 days divided by 30 days or 32.4% of the time. The line graph shows that out of 42 devices in the same category, this device was used more than 72% of the others (indicated to the left in green) and less than the remaining 28% (indicated to the right in white).

Used Devices by Site – These bar charts show how many medical IoT devices were used at each site within the filter parameters. The number of devices that were in use during the filtered time range is shown in relation to the total number of devices at each site over the past year.

If you filter the dashboard to show data for a single site, this panel shows not only the devices that were in use at this site but also other sites that had active devices to provide a reference for comparison.

Scanning Data by Site – When the medical IoT device category is for imaging devices, this information panel shows the number of scanned images and cases for each site with active devices. Click Cases or Images to toggle between them.

If you filter the dashboard to show data for a single site, this panel shows not only scanning data for this site but also other sites that have scanning data to provide a reference for comparison.

Average Usage by Site – When you set Infusion System as the medical IoT device category filter, this information panel shows the average device usage at each site. The average is calculated by dividing the total number of hours that devices at a site were in use during the time filter (1 week, 1 month, or 3 months) by the total number of devices in use at that site during the same time. Any devices that were not in use during that time are excluded from the calculation. In short, hours in use / devices in use = average usage.

If you filter the dashboard to show data for a single site, this panel shows not only the average usage of infusion systems for this site but also that of other sites with active infusion systems to provide a reference for comparison.
