The Raman spectra are derived from the laser light reflected back into the probe and captured by a charge coupled device (CCD) in the spectroscope. Computer software algorithms are used to deconvolute the CCD information into an interpretable Raman spectrum.'}], 'secondaryOutcomes': [{'measure': 'Wound temperature post-Transcutaneous Raman Spectroscope', 'timeFrame': 'Baseline then monthly for 3 months', 'description': 'Local temperature measurements of the wound will be collected before and immediately after the Raman measurements using a commercially available non-contact infrared thermometer which is also used to measure temperature in pediatric patients'}]}, 'oversightModule': {'oversightHasDmc': False}, 'conditionsModule': {'keywords': ['Foot ulcer, diabetic', 'Spectrum analysis, Raman'], 'conditions': ['Diabetic Foot Ulcer']}, 'descriptionModule': {'briefSummary': 'The primary translational research objective of the study is to demonstrate feasibility of using the Transcutaneous Raman Spectroscopy technology in a point-of-care environment. This study represents an initial evaluation of the device in a small cohort of human patients with diabetic foot ulcers.

The probe will never be in contact with the wound, but we will sterilize the probe head in advance in order to ease potential concerns regarding equipment sterility. A single point TRS measurement can be obtained in less than 60 seconds. At a minimum we will collect measurements at the geometric center of the wound as well as at the "6 and 12" and "3 and 9" ulcer coordinates. These coordinates are commonly used to estimate ulcer dimensions. It is anticipated that the PhAT probe will be used with a beam diameter of 7.5 mm. It is possible that the incident laser beam diameter will need to be adjusted (7.5 mm to 6.0 mm) to accommodate smaller wounds. If incident laser beam diameter adjustment is necessary we will also adjust the laser intensity to maintain the maximum permissible exposure of 0.3 W/cm2 per ANSI guidelines.', 'armGroupLabels': ['TRS']}]}, 'contactsLocationsModule': {'locations': [{'zip': '48109', 'city': 'Ann Arbor', 'state': 'Michigan', 'country': 'United States', 'facility': 'University of Michigan', 'geoPoint': {'lat': 42.27756, 'lon': -83.74088}}], 'overallOfficials': [{'name': 'Blake Roessler, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of Michigan'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Michigan', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Professor', 'investigatorFullName': 'Blake Roessler', 'investigatorAffiliation': 'University of Michigan'}}}}
