    摘要： Apparatus, catheter and method for obtaining information regarding a tissue structure (e.g., a blood vessel) can be provided. For example, it is possible to utilize a transceiving arrangement which includes at least one section adapted to be provided in a proximity of at least one portion of the tissue structure and in a bodily fluid, and which is adapted to transmit and receive electromagnetic radiation. The bodily fluid may be blood, pus, necrotic debris, mucus, urine and/or fecal matter.

    摘要： A system, process and software arrangement are provided to determining data associated with at least one structural change of tissue. In particular, a first optical coherence tomography (“OCT”) signal which contains first information regarding the tissue at a first stress level, and a second OCT signal which contains second information regarding the tissue at a second stress level are received. The first and second information are compared to produce comparison information. The data associated with the at least one structural change is determined as a function of the comparison information and further information associated with (i) at least one known characteristics of the tissue and/or (ii) characteristics of an OCT system. Further, at least one optical coherence tomography (“OCT”) signal which contains information regarding the tissue can be received, and the modulus of the tissue may be determined as a function of the received at least one OCT signal.

    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.
