In the specific case of free hand delivered catheters, the insertion point may be directly selected by the human expert. Using monitoring of the catheter position by additional imaging modalities such as magnetic resonance imaging or ultrasound imaging, the method enables real-time orientation guidance and adaptive dose correction in the course of treatment delivery."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Positioning assistance device for focal radiation therapy","description":"An efficient direct parameter optimization (DPO) approach is provided, in which a dosimetry gradient-based iterative greedy technique is applied to determine positioning assistance information for cat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11291863","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.
