摘要： A brachytherapy applicator and method of use involve source guides that assume a desired curving, non-linear configuration. A flexible source catheter follows the shape of the source guides when inserted therein. Radiation dose received in various tissue areas can be better controlled using the invention, and the ratio of cavity surface dose to prescription depth dose can be lowered. With sequential manipulation of the source via movement of the catheter, the applicator can deliver radiotherapy to a treatment plan with local variation to prevent overdose, through either stepped or continuous movement of the source. Source guides can be fixed in position and arranged in bowed configuration around a generally central balloon axis, either attached to the balloon wall or not, and the series of off-center guides can be used to shape the dose delivered.

摘要： A brachytherapy applicator and method of use involve a source guide that assumes a desired curving, non-linear configuration when inserted into an inflated balloon of the applicator. A flexible source catheter follows the shape of the source guide when inserted into the balloon. Radiation dose received in various tissue areas can be better controlled using the invention, and the ratio of cavity surface dose to prescription depth dose can be lowered. With rotation of the curving source guide coupled with translation of the source via longitudinal movement of the catheter, the applicator can approximate a spherical source, through either stepped or continuous movement of the source and source guide.

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： A small tabletop stationary five-degree of freedom device such as a “robot” is used to define the treatment region by tracing the region under direct visualization and then to precisely deliver the treatment plan created by an automatic planning system by positioning a single low energy radiation source, or a plurality of low energy sources connected to each other in a predetermined parallel or similar geometry, each source equipped with blocking and attenuation mechanisms, at a plurality of positions in a planar fashion across or through a selected treatment field, thereby delivering a plurality of parallel overlapping beams indexed on a millimeter or submillimeter grid such that a concentration of dose is achieved at a variable depth in tissue relative to the dose where the radiation first enters the tissue and can be used to treat regions on or below the surface of tissue, in a cavity and underlying region created following a surgical resection, on or below the surface of an internal cavity, hollow viscus, or lumen, or deep in tissue adjacent to an inserted probe or conduit or catheter. By generating a plurality of overlapping beams indexed on a millimeter or submillimeter grid that converge on a target volume loaded with gold nanoparticles, a tumorcidal dose of radiation can be delivered in as little as a single session to tumor cells but not to normal cells within or outside the treatment volume. This approach also makes it possible to deliver serial radiosurgical treatments.
