It wasn't until the invention of the MR and really the integration of MR with focused ultrasound that we could get the feedback -- both the anatomical and the physiological in order to have a completely noninvasive, closed-loop surgical procedure.
Abia după inventarea rezonanţei magnetice mai exact integrarea RMN-ului cu ultrasunete focalizate am putut obține feedbackul necesar -- anatomic și fiziologic, ca să închidem bucla unui procedeu chirurgical non-invaziv.
