摘要： Systems, methods, and related computer program products for non-invasive NIR spectrophotometric (NIRS) monitoring of total blood hemoglobin levels and/or other blood constituent levels based on a hybrid combination of phase modulation spectrophotometry (PMS) and continuous wave spectrophotometry (CWS) are described. PMS-based measurements including both amplitude and phase information used in the determination of a non-pulsatile component of an absorption property for each of at least three distinct wavelengths are processed to compute PMS-derived intermediate information at least partially representative of a scattering characteristic. CWS-based measurements including amplitude information is processed in conjunction with the PMS-derived intermediate information to compute a pulsatile component of the absorption property. A metric representative of at least one chromophore level, such as the total blood hemoglobin level, is computed from the pulsatile component of the absorption property at the at least three wavelengths and displayed on an output display.

摘要： A combined ultrasonic and endoscopy system (100) includes a cannula (240) with a distal tip (250) configured for insertion into an internal organ or other internal body structure. The distal tip (250) is configured to include both an ultrasound probe head (252) and a camera module (320). The ultrasonic and direct vision endoscopy images (154, 156) can be simultaneously displayed to a user on a display monitor (150, 152). The ultrasound probe head (252) can be rotated and steered to scan any location in the human organ cavity. The ultrasound probe (410) can be re-usable or single use. The system (100) can be configured with a handheld portion (110) that includes a re-usable handle portion (130) and a single use portion (120) that is configured to be disposed of following a single use. The system (100) can also be configured using a conventional re-usable endoscope with working channels (920, 1020) and an endoscopy processing tower system (112, 116, 118).

摘要： A method and system comprising a full-filed breast ultrasound (FFBU) scanner (102), a viewing workstation (104), and an archive (106) are described for obtaining, processing, and/or and archiving (FFBU) data, in a manner that promotes ready integration with current x-ray mammogram-based breast cancer screening methodologies, and which can alternatively be used to support a full-field-only environment. Two-dimensional thick-slice images computed from a three-dimensional data volume are used to facilitate efficient archiving for a breast imaging session, the two-dimensional thick-slice images corresponding to slab-like subvolumes of the breast. Clinician data overload problems that can arise from the existence of large amounts of three-dimensional full-field breast image data are reduced. Archive space is also preserved while still providing sufficient information data for future reference purposes. Related adjunctive full-field workflow methods are also described. The described embodiments are applicable to FFBU imaging and other full-field breast imaging modalities such as MRI, CT, PET, and others.

摘要： An apparatus and related methods for scanning a breast are described, the apparatus comprising a frame defining an orifice shaped to allow the breast to be received therein, a compressive member secured to the frame across the orifice that compresses the received breast toward the patient's chest wall, and a transducer positioned in acoustic communication with the compressive member for imaging the breast therethrough. The frame holds a reservoir of acoustically conductive fluid that maintains the transducer in acoustic communication with the compressive member. In different preferred embodiments having different advantages, the compressive member comprises a flexible elastic membrane, a flexible inelastic membrane, or a rigid sonolucent plastic preformed into the shape of a chestwardly-compressed breast. Where the transducer comprises one or more linear array probes, various probe orientations and trajectories are described for generating a three-dimensional volumetric representation of the breast having reduced nipple shadow effects.

摘要： A full-field breast ultrasound (FFBU) scanning apparatus and related methods are described for compressing and ultrasonically scanning a breast. A first surface of an at least partially conformable, substantially taut membrane or film sheet compresses one side of the breast, and the other side of the breast is compressed by a compression assembly comprising a rigid compression plate and an inflatable air bladder. A transducer translation mechanism holds a transducer surface against a second surface of the film sheet while translating the transducer thereacross to scan the breast. An irrigation system automatically maintains a continuous supply of coupling agent at an interface between the transducer surface and the film sheet as the transducer is translated. A recycling system collects used coupling agent for re-use by the irrigation system. The transducer is housed in a substantially closed environment to prevent evaporative acoustic couplant loss and to allow scanning at many different angles without couplant loss. A variety of other usability, patient comfort, and safety features are also described.
