  • Patent number: 9588099
    Abstract: Apparatus and methods are provided for the imaging of structures in deep tissue within biological specimens, using spectral imaging to provide highly sensitive detection. By acquiring data that provides a plurality of images of the sample with different spectral weightings, and subsequent spectral analysis, light emission from a target compound is separated from autofluorescence in the sample. With the autofluorescence reduced or eliminated, an improved measurement of the target compound is obtained.

  • Patent number: 9572529
    Abstract: Surgical devices and methods for utilizing optical coherence tomography (OCT) to monitor and control tissue sealing are disclosed. The surgical device includes an end effector assembly that includes first and second jaw members that are movable between a first, spaced-apart position and a second proximate position. An OCT system, at least a portion of which is incorporated into the end effector assembly, is configured to sense properties of the tissue, e.g., the structural density of the tissue, disposed between the first and second jaw members. A tissue-sealing energy source may be disposed within at least one of the jaw members and may provide tissue-sealing energy to tissue disposed between the jaw members. A controller, which is coupled to the OCT system and the tissue-sealing energy source, controls the tissue-sealing energy generated by the tissue-sealing energy source based on the properties of the tissue sensed by the OCT system.

  • Patent number: 9575148
    Abstract: In a method for guiding brachytherapy radiation treatment the patient is supported on a table and an MR magnet is brought into the treatment bunker through doors for imaging while the after-loader for the radiation source delivery is stored away in a storage location outside the RF shield. A safety system controls movement of the after-loader and the magnet. Images of the patient obtained while the patient is on the table are used to locate the applicator with respect to the lesion and organs-at-risk. The MR and X-ray compatible patient support table with MR coil integration includes a removable end-extension, which provides pelvic access for applicator insertion.

  • Patent number: 9566455
    Abstract: A system and method for fluid control in a thermal therapy system is disclosed. A fluid circuit permits passage of a fluid through a fluid circuit, including into and out of a treatment zone so as to cool or heat or maintain a temperature in said treatment zone at or near a desired temperature. The temperature is sensed at a point in the circuit between a discharge of a fluid pump and the treatment zone. MRI based thermometry of tissue in the treatment zone is accomplished in some aspects. Furthermore, a desired temperature may be programmably set to a given value or within a band of values using a processor and a temperature controller. In some aspects, leakage of fluid from a patient or from the fluid control system is captured by a leak-proof member to protect imaging and treatment equipment from damage.

  • Patent number: 9571166
    Abstract: Methods and systems for determining one or more parameters of a tuned circuit forming part of a wireless energy transmission system in an implanted (or implantable) medical device are described. The method involves energizing the tuned circuit then receiving a signal back from it. This signal is then analyzed to determine a property of the circuit such as its quality factor (Q) or resonant frequency. Also described herein is a method and system for determining the implantation depth of a component of an implanted medical device. The method involves determining the position of a magnetic element which is mounted in a fixed physical relationship with the component of the medical device. The methods can be performed on an implanted medical device without the need to explant the device.

  • Patent number: 9561017
    Abstract: The present disclosure provides for a system that is adapted to simultaneously display photoacoustic and ultrasound images of the same object. An image combiner can perform spatial and temporal interpolation of the two images before generating a combined image. The combined image is then displayed on a display such as an LCD or CRT. The system is able to use motion estimates obtained from the ultrasound data to enhance the photoacoustic image thereby increasing its apparent frame rate, registering consecutive frames in order to reduce artifacts. The system is capable of generating combined ultrasound and photoacoustic images which are registered spatially and temporally.
