After subject enrollment the microwave measurement will be performed. The procedure will take approximately 15 minutes (the duration of the actual measurements is \\< 1 minute) and will not interfere with the patient's standard of care at the Stroke Unit.\n\nThe measurement data will be evaluated for the presence of signal artifacts. The diagnostic ability of the device will be evaluated using a leave-one-out cross validation method with the CT diagnosis as ground truth. Microwave signals are sensitive to the dielectric parameters of the investigated object. In biological matter this is often related to amount of water. Brain tissue has different dielectric properties from blood. The physiological changes inside the brain that occurs as a result of a stroke will change the dielectric parameters."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n(Group A)\n\n* Signed Informed Consent Form\n* Patient diagnosed (by CT) with ischemic stroke, within 24 hours of stroke onset\n* Patient should be ≥ 18 years of age\n\n(Group B)\n\n* Signed Informed Consent Form\n* Patient diagnosed (by CT) with hemorrhagic stroke, within 48 hours of stroke onset\n* Patient should be ≥ 18 years of age\n\n(Group C)\n\n* Signed Informed Consent Form\n* Subject should be ≥ 18 years of age\n\nExclusion Criteria:\n\n(Group A+B)\n\n* Pregnant or nursing woman\n* Woman of child bearing potential and not taking adequate contraceptive precautions\n* Patient that has already received thrombolytic treatment\n* Patient participating in any other clinical study that could interfere with the result in the present study\n* Patient diagnosed with a condition associated with risk of poor protocol compliance\n* Any other condition or symptoms preventing the patient from entering the study, according to the investigator´s judgment\n* Any patient that according to the Declaration of Helsinki is deemed unsuitable for study enrollment\n\n(Group C)\n\n* Pregnant or nursing woman\n* Woman of child bearing potential and not taking adequate contraceptive precautions\n* Subject participating in any other clinical study that could interfere with the result in the present study\n* Any other condition or symptoms preventing the subject from entering the study, according to the investigator´s judgment\n* Any subject that according to the Declaration of Helsinki is deemed unsuitable for study enrolment'}, 'identificationModule': {'nctId': 'NCT02266459', 'briefTitle': 'Study to Evaluate Performance, Usability, Safety of Microwave Technology When Collecting Data From Patients With Stroke', 'organization': {'class': 'INDUSTRY', 'fullName': 'Medfield Diagnostics'}, 'officialTitle': 'A Prospective, Open, Multicenter Study to Evaluate the Performance, Safety and Usability of the Microwave Technology Developed by Medfield Diagnostics When Collecting Measurement Data From Patients With Clinical Signs of Stroke.', 'orgStudyIdInfo': {'id': 'MF04'}}, 'armsInterventionsModule': {'interventions': [{'name': 'Microwave technology (Medfield Diagnostics)', 'type': 'DEVICE', 'description': "A microwave measurement will be performed.
