摘要:
The present invention relates to tissue imaging. In order to provide a further improved hyperspectral imaging, a hyperspectral imaging system (10) for medical application is provided that comprises a hyperspectral camera (12), a first illumination arrangement (14), a second illumination arrangement (16), a target arrangement space (18), and a processing unit (20). The target arrangement space is provided to arrange tissue of interest (22) therein for hyperspectral imaging of the tissue. The hyperspectral camera is arranged on a first side of the target arrangement space. The first illumination arrangement is configured to provide top illumination (24) from the first side to a tissue provided in the target arrangement space; and the second illumination arrangement is configured to provide back illumination (26) from a second side to the tissue, wherein in relation to the target arrangement space the second side is opposite to the first side, and wherein the second illumination arrangement is provided as an insertable light source. The hyperspectral camera is configured to provide first hyperspectral image data based on the top illumination and second hyperspectral image data based on the back illumination. Further, the processing unit is configured to combine the first hyperspectral image data and the second hyperspectral image data to generate combined hyperspectral image data of the tissue of interest.
摘要:
A probe and connected system provide ultrasound imaging and optical tomographic imaging of the prostate. A transrectal component carries ultrasound and optical sources and detectors movably connected to a reference element called a probe carrier that provide a reference frame to coregister anatomical and optical tomographic image data.
摘要:
A beam-shaping optical system includes a sheath defining a central cavity having an inner wall, an optical fiber positioned within the cavity and engaged with the inner wall of the sheath, and a beam-shaping insert positioned within the sheath and engaged with the inner wall of the sheath. The beam-shaping insert includes a beam-shaping element with a reflective element aligned with an optical axis of the optical fiber. The optical fiber is configured to emit an electromagnetic beam toward the beam-shaping element and the beam-shaping element is configured to reflect the electromagnetic beam externally to the beam-shaping insert.
摘要:
Tip confirmation systems and related methods are disclosed. A method of determining one or more properties of a catheter (200) in a patient comprises advancing a catheter in vasculature of a patient, the catheter coupled to at least one radiation source and at least one detector, transmitting source electromagnetic radiation from the at least one radiation source out of the catheter proximate a distal tip thereof, measuring an intensity of backscattered electromagnetic radiation from the at least one radiation source with the at least one detector, and providing a signal indicative of a location of the distal tip within the vasculature based, at least in part, on the measured intensity of the backscattered electromagnetic radiation. Related systems and methods are also disclosed.
