A system for detecting and destroying living tumor tissue within the body of a living being. The system is arranged to be used with a tumor localizing radiopharmaceutical. The system includes a percutaneously insertable radiation detecting probe, an associated analyzer, and a percutaneously insertable tumor removing instrument, e.g., a resectoscope. The radiation detecting probe includes a needle unit having a radiation sensor component therein and a handle to which the needle unit is releasably mounted. The needle is arranged to be inserted through a small percutaneous portal into the patient's body and is movable to various positions within the suspected tumor to detect the presence of radiation indicative of cancerous tissue. The probe can then be removed and the tumor removing instrument inserted through the portal to destroy and/or remove the cancerous tissue. The instrument not only destroys the tagged tissue, but also removes it from the body of the being so that it can be assayed for radiation to confirm that the removed tissue is cancerous and not healthy tissue. A collimator may be used with the probe to establish the probe's field of view.
A system for determining the three dimensional representation of living tumor tissue within the body of a living being, said system comprising a tumor localizing radiopharmaceutical and small diameter penetratable radiation detecting means, said tumor localizing radiopharmaceutical being attached to the living tumor tissue, whereupon said radiopharmaceutical produces tumor-localizing radiation from the living tumor tissue, said tumor-localizing radiation comprising photons of different energies produced by said radiopharmaceutical, said small diameter penetratable radiation detecting means being arranged to be inserted into the body of the being with minimal invasion of the being via a percutaneous incision or access port and being movable along a path within the tumor tissue for location at various positions within the tumor tissue for detecting said tumor localizing radiation from a plurality of directions therein to provide an indication of the three dimensional distribution of the living tumor tissue to which said radiopharmaceutical is attached and for providing a signal indicative thereof.
A system for detecting and destroying living tumor tissue within the body of a living being, said system comprising a tumor localizing radiopharmaceutical, a small diameter tissue-penetratable radiation detecting means, and tumor destroying means, said tumor localizing radiopharmaceutical being attached to the living tumor tissue, whereupon said radiopharmaceutical produces tumor-localizing radiation from the living tumor tissue, said small diameter tissue-penetratable radiation detecting means being arranged to be inserted into the body of the being with minimal invasion of the being via a percutaneous incision or access port into the tumor tissue and being movable along a path within the tumor tissue for location at various positions therein for detecting said tumor localizing radiation from a plurality of directions and for providing a signal indicative of the three dimensional distribution of the living tumor tissue to which said radiopharmaceutical is attached, said tumor destroying means being arranged to be inserted into the body of said being into said living tumor tissue for destroying said living tumor tissue from within it.
A probe for detecting radiation from living tumor tissue tagged with a radiopharmaceutical within the body of a living being, the radiopharmaceutical producing tumor-localizing radiation from the living tumor tissue, said probe being an elongated member comprising a radiation sensor and radiation detection enhancing means, said probe being arranged to be inserted into the body of the being adjacent the tumor tissue for detecting said tumor localizing radiation from a plurality of directions and for providing a signal indicative of the three dimensional distribution of the living tumor tissue to which said radiopharmaceutical is attached, said radiation detection enhancing means comprising a hollow member including barrier wall defining a hollow interior, said barrier wall being disposed adjacent said sensor for blocking radiation to said sensor from various directions, said barrier wall having an opening in communication with said hollow interior through which radiation may pass whereupon the radiation is reflected from said barrier wall to said sensor.
