    摘要: A system and method for optical lymph node mapping. The system is useful for guiding sentinel lymph node biopsy surgeries. A contrast agent that includes a fluorescent dye is injected near the site of a malignancy. The contrast agent drains into the lymphatic system, collecting in a sentinel node or nodes. The system utilizes one or more low-power continuous-wave lasers or light-emitting diodes modulated with a digital code sequence to probe the tissue suspected of containing the sentinel node. When the light is incident near the sentinel node, it will excite fluorescence from the dye. A portion of the scattered fluorescent light is captured with one or more photo-detectors. A correlation of the photo-detector signal and the digital code sequence is calculated to produce an estimate of the distribution of flight times for photons traveling from a given source to a given detector. The flight time distributions are used along with the measured amplitudes to reconstruct a map of contrast agent location within the tissue.

    摘要: Methods and systems for monitoring contact between a medical probe and tissue are provided. A medical probe is introduced into a patient adjacent the tissue. An electrical parameter, e.g., electrical admittance, is measuring between a first electrode located on the medical probe and a second electrode remote from the first electrode. The electrical parameter is amplitude modulated in response to a physiological cycle of the patient. Contact between the medical probe and the tissue is detected based on the amplitude modulation of the measured electrical parameter.

    摘要: Tools and methods are provided for dissecting and/or removing biological units, such as hair follicles, from the body surface based on the images both above and below a body surface to reduce potential damage to the removed biological unit. The invention may be used in fully automated systems and also in a hand-held devices and systems. A system may produce a series of three-dimensional images of the body surface indicating follicular unit size, shape, position, and orientation both above and below the skin surface. The images may be utilized by an automated follicular unit harvesting tool, or maybe stored for later use. Imaging techniques include devices that sense light in the visible or infrared spectrums, optical coherence tomography, and ultrahigh frequency ultrasound.
