The prostate tissue phantom is a polyvinyl alcohol cryogel (PVA-C) having undergone 3-5 freeze-thaw cycles and having 10-20% w/w PVA in a solvent (e.g. water), 4-8% w/w oil and an amount of acoustic scattering particles to ultrasonically distinguish the prostate-tissue phantom from its surroundings. The perineal tissue phantom is a PVA-C having undergone 1-2 freeze-thaw cycles and having 10-20% w/w PVA in a solvent, 4-8% w/w oil and an amount of acoustic scattering particles to ultrasonically distinguish the perineal tissue phantom from its surroundings. The skin tissue phantom is a PVA-C having undergone at least 6 freeze-thaw cycles and having 15-25% w/w PVA in a solvent. The phantom mimics the imaging and mechanical properties of the prostate and surrounding tissues, providing a realistic phantom for prostate cancer brachytherapy."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tissue-mimicking phantom for prostate cancer brachytherapy","description":"A phantom for prostate cancer brachytherapy has a prostate tissue phantom shaped like a real prostate gland, a perineal tissue phantom surrounding the prostate tissue phantom, a skin tissue phantom se","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8480407","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
