In a preferred embodiment the object is a foot and the device is useful in determining the presence of osteoporosis. Ultrasonic transmitter (34) is resiliently mounted in a first container (30) slidably received in the main body (10). The transmitter (34) is urged towards the object (14) but its movement is restricted. A piezoelectric ultrasonic receiver (48) spaced from the transmitter (34) also projects towards the body (14). The ultrasonic receiver (48) is resiliently mounted in a second hollow container (52) slidably received in the main body (10). The object (14) is subjected to a first frequency obtained by resonating the transmitter (34) in the thickness mode and a second lower frequency obtained by resonance in the radial mode.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the complete Patent AT-E401826-T1: [Translated] ULTRASONIC SCANNING DEVICE on the official website.", "downloadURL": "https://pubchem.ncbi.nlm.nih.gov/patent/AT-E401826-T1", "mediaType": "text/html", "title": "Official Data Source"}], "identifier": "https://healthdata.gov/api/views/a4dq-7kt9", "issued": "2025-09-05", "keyword": ["chemistry", "innovation", "patent", "pubchem", "research"], "landingPage": "https://healthdata.gov/d/a4dq-7kt9", "modified": "2025-09-06", "programCode": ["009:066"], "publisher": {"@type": "org:Organization", "name": "National Center for Biotechnology Information (NCBI)"}, "theme": ["NIH"], "title": "Patent AT-E401826-T1: [Translated] ULTRASONIC SCANNING DEVICE"}
