METHODS AND SYSTEMS FOR DETECTING SUB-TISSUE ANOMALIES

摘要

A diagnostic imaging device includes a probe that uses both an ultrasound transducer and frequency-domain diffuse optical imaging (FD-DOI) to assist with locating and diagnosing sub-tissue anomalies. According to one aspect, the diagnostic imaging device relates to a clip-on cap that can be utilized with existing ultrasound transducers. The diagnostic imaging device described herein can be utilized for image-guided needle biopsy to regions where prostate tissues are highly suspicious for high-grade cancer, as well as for image guided interventions, such as cryotherapy, photodynamic therapy, and brachytherapy for early-stage or localized prostate cancer.

主权项

1. An ultrasound transducer cap (10), comprising:
a hollow body (12) with an internal cavity that compliments an ultrasound transducer (22), the hollow body (12) comprising:
an ultrasound transducer cutout (18) disposed along a length of the hollow body (12) that provides an unblocked line of sight between an ultrasound transducer (22) within the hollow body (12) and a rectal wall (62);a first light emitter (14) disposed along a first edge (26) of the ultrasound transducer cutout (18); anda first light detector (16) disposed along a second edge (28) of the ultrasound transducer cutout (18).
