an experimental protocol for assessing the performance of new ultrasound probes based on cmut technology in application to brain imaging

성능 이미징의 초기 및 반복 가능한 평가 수행할 가능성이 설계에 기본 이며 개발 과정 (미국) 새로운 초음파 프로브. 특히, 응용 프로그램별 이미징 목표 보다 현실적인 분석 응용 프로그램의 그들의 잠재적인 임상 분야에서 미국 프로브의 예상된 성능을 평가 하 매우 유용할 수 있습니다.
이 작품에서 제시 하는 실험 프로토콜 고의로 응용 프로그램별 평가 절차는 새로 개발 된 우리 제공 하도록 설계 되었습니다 관련 용량 성 휘트스톤 초음파 변환기 (CMUT) 기술을 기반으로 하는 프로토 타입 프로브 뇌 이미지입니다.
프로토콜은 리얼리즘과 설명된 절차 그리고 neuronavigation 기술 신경외과에서 빌린의 반복성을 보장 하는 이미징 대상으로 포 르 말린에 고정 하는 소 뇌를 사용 하 여를 결합 합니다. 미국 조사 사실 모션 추적 위치 데이터를 획득 하 고 미국 이미지 참조 뇌의 자기 공명 (MR) 이미지의 중첩을 가능 하 게 하는 시스템에 연결 됩니다. 이 성능 이미징 미국 탐사선의 시각 질적 평가 수행 하 고 인수 다른 프로브로 만든 비교 인간의 전문가 위한 수단을 제공 합니다. 또한, 프로토콜 초음파 플랫폼 오픈 고급 (울 라-OP) 스캐너 미국 이미지 수집, 즉 완전 하 고 개방 연구 및 개발 시스템의 사용에 의존합니다.
악기와 관련 프로토콜, 특히 교정, 이미지 수집 및 미국 및 미스터 이미지의 등록 절차는 원고는 자세하게에서 설명 합니다. 얻은 결과 전적으로 열 (의 한계 내에서 관련 된 계측), 반복, 그리고 미국 이미지 수집 및 처리 활동의 전체 집합을 포함, 전체 프로토콜의 효과 증명.

설명 된 프로토콜을 통해 달성 하는 주요 결과 2D에 대 한 효과적이 고 반복 가능한 평가 절차의 실험 유효성 검사 이며 우리 3D 이미징 기능 프로브 뇌에 미래의 응용 프로그램에서 CMUT 기술을 기반으로 하는 프로토 타입 이미지입니다. 모든 설명된 프로토콜 단계 구현 후 전문가 적용할 수의 시각적 내용을 비교 하 시각화 소프트웨어 기능 (예: 무료 방향 슬 라이 싱,...
