    摘要: The invention relates to a medical imaging apparatus for providing information about an object. The invention further relates to a method for providing information about an object. In order to improve the preparation and the visual reception of information relating to an object during medical interventions, a medical imaging apparatus for providing information about an object is provided that comprises an image acquisition device an interventional device, a processing device and a display device. The image acquisition device detects object data from at least one region of interest of an object and provides the object data to the processing device. The interventional device detects physiological parameters of the object depending on the position of a predetermined area of the interventional device in relation to the object and provides the physiological parameters to the processing device. Further, the processing device transforms at least a part of the object data into image data and converts the physiological parameters into physiological data. The processing device then modifies at least one image parameter of the image data depending on the physiological data and thereby transforms the image data into modified live image data which is provided to the display device displaying a modified live image.

    摘要: The present invention relates to an optical probe (1) suitable for miniature applications. An example application is a fibre-based confocal miniaturized microscope. The optical probe comprises a coil-based actuation system (9, 10) comprising drive coils (9) capable of displacing the distal end (3) of an optical guide (2) housed (4) by the optical probe. The probe makes use of a feedback loop which alternate between driving the displacement of the optical guide by driving a current through the drive coils and switching off the current through the drive coils, and while the drive current being switched off, measure the speed of the distal end of the optical guide. The measured speed is compared to the set-point speed, and if a difference is detected, the drive current is adjusted to eliminate, or at least bring down, this difference.

    摘要: The present invention relates to an optical probe (1) with an optical guide (2), e.g. an optical fibre, and a lens system (6) rigidly coupled to an end portion (2a) of the optical guide. The probe has a housing (3) with a cavity for the optical guide, the housing having at its distal end a transparent window (4), the window having an insignificant optical power as compared to the optical power of the said lens system (6). Actuation means (8) displaces the 5 lens system so as to enable optical scanning of a region of interest (ROI). The invention is particularly suited for miniature applications e.g. for in-vivo medical application. By attaching the lens system (6) to the optical guide (2) via the mount (7), the field of view (FOV) of the optical probe (1) may be determined directly by the transverse stroke of the optical fibre (2). Hence only a relatively small stroke is required. The field of view is thus 10 effectively no longer limited by the transverse stroke. The optical probe is especially advantageous for non-linear optical imaging where the optical guide may be an optical fibre with a relatively low exit numerical aperture.
