ABSTRACT:
The present invention relates to a method of detecting an abnormality of cell growth in an organ or tissue of a body and various optical assemblies for accomplishing the same. The present invention has discovered that diagnosis of incipient abnormal tissue growth such as cancer can be accomplished in vivo by exerting a predetermined pressure on the suspected tissue or organ and by subsequently comparing the relative effect on reflection from or light absorption of the tissue or organ. An optical probe can be utilized for scanning the suspected tissue or organ and recording an initial reflecting characteristic. Subsequently the tissue or organ is placed under a predetermined pressure to provide a second reflection characteristic. A comparison of the two signals will permit a diagnosis of the condition of the tissue or organ. As can be appreciated, a fiber optic bundle can be used for the optical probe and a data processor can automatically compute either the difference or the ratio of the two signals with a corresponding display or printing of the information. Alternative embodiments are disclosed herein.
