摘要:
Accordingly, exemplary embodiments of an apparatus probe catheter and method can be provided for irradiating a structure. In particular, an interferometer may forward forwarding an electromagnetic radiation. In addition, a sample arm may receive the electromagnetic radiation, and can include an arrangement which facilitates a production of at least two radiations from the electromagnetic radiation so as to irradiate the structure. Such exemplary arrangement can be configured to delay a first radiation of the at least two radiations with respect to a second radiation of the at least two radiations.

Exemplary method, apparatus and arrangement can be provided for obtaining information associated with a sample such as a portion of an anatomical structure. The information can be generated using first data, which can be based on a signal obtained from a location on the sample, and second data, where the second data can be obtained by combining a second signal received from the sample with a third reference signal. An image of a portion of the sample can also be generated based on the information. For example, the first data can be associated with spectral encoding microscopy data, and the second data can be associated with optical coherence tomography data.

Exemplary embodiments of apparatus, source arrangement and method for, e.g., providing high-speed wavelength tuning can be provided. According to one exemplary embodiment, at least one arrangement can be provided which is configured to emit an electromagnetic radiation that (i) has a spectrum whose mean frequency changes at an absolute rate that is greater than about 6000 (or 2000) terahertz per millisecond, (ii) whose mean frequency changes over a range that is greater than about 10 terahertz, and/or (iii) has an instantaneous line width that is less than about 15 gigahertz. According to another exemplary embodiment, at least one arrangement can be provided configured to, periodically and as a function of time, select at least one first electro-magnetic radiation based on a mean frequency of the at least one first electro-magnetic radiation, with the periodic selection being performed at a first characteristic period. The mean frequency can vary linearly over time, wherein the apparatus can emit at least one second electromagnetic radiation that has a spectrum whose mean frequency changes periodically as a function of time with a second characteristic period. Further, the first characteristic period can be greater than the second characteristic period.
摘要:
An apparatus for needle biopsy with real time tissue differentiation using one dimensional interferometric ranging imaging, comprising a biopsy device having a barrel and a needle, an optical fiber inserted in the needle, and a fiber optic imaging system connected to the optical fiber. The imaging system obtains images and compares the optical properties and patterns to a database of normalized tissue sample images to determine different tissue types. The physician performing the biopsy obtains feedback via a feedback unit associated with the biopsy device and which is connected to the imaging system. The feedback unit can provide visual, audible or vibratory feedback as to tissue type encountered when the needle is inserted toward the target tissue. The feedback unit can be programmed for different biopsy procedures so that the user can actuate a button to select a display or other feedback mechanism for the desired procedure and anticipated tissue to be encountered.

A confocal microscope lens arrangement is provided. The confocal microscope lens arrangement includes a lens assembly housing which has a lens assembly, and an exterior housing including a distal end and a proximal end. The exterior housing is configured to allow the lens assembly housing to be placed therein, and translated between the proximal end and the distal end of the exterior housing to focus the lens assembly. The exterior housing has an aperture formed through a distal end thereof. The arrangement also includes an immersion media filling the volume of area between the exterior housing and the lens assembly housing.
摘要:
Exemplary apparatus and method for obtaining information associated with at least one image of at least one portion of a sample can be provided. For example, at least one first electro-magnetic radiation can be provided from the at least one portion (e.g., using a first electro-magnetic radiation guiding arrangement which is configured to provide). A plurality of spatial frequency bands of the image associated with the first electro-magnetic radiation can be generated. Further, at least one second electro-magnetic radiation which is associated with the spatial frequency bands of the image can be received (e.g., using a second arrangement), and the image can be reconstructed based on the spatial frequency bands.
摘要:
A scanning confocal microscopy system and apparatus, especially useful for endoscopy with a flexible probe which is connected to the end of an optical fiber (9). The probe has a grating (12) and a lens (14) which delivers a beam of multi-spectral light having spectral components which extend in one dimension across a region of an object and which is moved to scan in another dimension. The reflected confocal spectrum is measured to provide an image of the region.
