Abstract
Systems, methods and devices are provided for performing diagnostic or therapeutic transcranial procedures using a patient-specific transcranial headset. The patient-specific headset may include a patient-specific frame that is fabricated, according to volumetric image data, to conform to an anatomical curvature of a portion of a patient's head. The patient-specific frame is configured to support a plurality of transducers in pre-selected positions and orientations, which may be spatially registered to the volumetric image data. This spatial registration may be employed to control at least a portion of the transducers to focus energy at a pre-selected tissue region.

1-51. (canceled)
A system for performing diagnostic or therapeutic transcranial procedures, the system comprising:
- a patient-specific frame customized to specifically fit a head of a patient, such that when the patient-specific frame is placed on the head of the patient, the patient specific frame conforms to an anatomical contour of at least a portion of the head of the patient;
- the patient-specific frame comprising a plurality of ultrasound transducer attachment interfaces such that, when each ultrasound transducer attachment interface has a respective ultrasound transducer attached thereto and the patient-specific frame is worn by the patient, the plurality of ultrasound transducers respectively attached to the plurality of ultrasound transducer attachment interfaces reside in predetermined positions and orientations relative to the head of the patient as prescribed by transducer registration data spatially registering the plurality of ultrasound transducers with a frame of reference of volumetric image data associated with the patient;
- the system further comprising a data storage medium storing the transducer registration data.
A method of fabricating a patient-specific frame for diagnostic or therapeutic procedures, the method comprising:
- obtaining surface data characterizing an anatomical curvature of at least a portion of a head of a patient;
- employing the surface data to generate a digital model of a patient-specific frame that conforms to the anatomical curvature of the head of the patient, the digital model of the patient-specific frame being generated such that the patient-specific frame comprises a plurality of ultrasound transducer attachment interfaces, each ultrasound transducer attachment interface being configured to support attachment of a respective ultrasound transducer of a plurality of ultrasound transducers;
- generating transducer registration data that spatially registers the plurality of ultrasound transducers, when the plurality of ultrasound transducers are attached to the plurality of ultrasound transducer attachment interfaces, with a frame of reference of volumetric image data associated with the patient;
- and
- fabricating the patient-specific frame according to the digital model.
