Description of intervention(s) / exposure
This study is a continued innovation study for the development of additional software features for the emu™ Brain Scanner.

Participants who present to the hospital suspected of suffering from a suspected stroke or intracranial haemorrhage will receive an emu™ brain scan. emu™ device brain scans measure the dielectric properties of the brain using non-invasive, non-ionising, low-energy, electromagnetic pulses.

During an emu™ brain scan procedure, the emu™ is brought bedside to a participant lying supine on a hospital bed. A headset housing an array of antennae is placed on the head, where the headset membrane inflates with a coupling fluid to conform to the shape of the head during which the scans take place.

Participation in this study consists of a single visit taking place in the hospital and consists of a single brief scan procedure (typically under six minutes) conducted by a qualified nurse or physician. Study participation is considered complete upon positive radiological confirmation of the presenting condition, patient discharge, or 28 days, whichever is earliest. No procedures are required of the participant following the initial emu™ brain scan.

Nurses and physicians responsible for conducting scans will receive two hours of face-to-face training or refresher training with EMVision trainers approximately one week prior to enrolment of the first participant. All scan data is reviewed by EMVision engineers to verify scanning procedures are conducted to an appropriate standard.

Comparator / control treatment
Participants will act as their own control. The comparator radiological imaging (either CT or MR imaging) and its associated duration is at the determination of the participants’ physicians and is part of the standard of care stroke workflow, typically approximately 30 minutes. The emu™ brain scan will be conducted within 30 minutes to neurological imaging, either prior to or immediately after imaging with priority given to standard-of-care imaging. Follow-up standard-of-care imaging within 28 days of presentation may be used to confirm the diagnosis should initial imaging results be inconclusive. This study does not require any additional interventions to their standard-of-care medical imaging.
