Abstract

"ESPIRA RECEPTORA DE IMAGEM DE RESSON NCIA MAGNéTICA". A referida espira receptora (10) inclui um primeiro balão (12) tendo um eixo longitudinal. Uma superfície interna do primeiro balão (12) define uma câmara inflável interna. Um segundo balão (14) tem um eixo longitudinal. O segundo balão (14) é disposto em torno do primeiro balão (12). Múltiplos sulcos (16, 18, 20, 22) estendidos longitudinalmente são dispostos em uma superfície externa do primeiro balão (12) e a superfície interna do segundo balão (14). Um primeiro fio (28) é disposto em pelo menos um dos sulcos. Um segundo fio (30) é disposto em pelo menos um segundo sulco dentre os sulcos (16, 20, 22). O primeiro fio (28) e o segundo fio (30) são, cada um, adaptados para serem conectados eletricamente e um aparelho de MRI.
