Abstract
A system for describing the physical distribution of an agent that accumulates selectively in tissue of a patient in an excised surgical specimen. The system comprises an agent which selectively concentrates in a cancer or precancer or focus of infection or other pathological condition. The system comprises a detector sensitive to the agent which is present in the surgical specimen. The system also comprises an apparatus capable of forming an image based on the information gathered by the detector, and which image describes the physical distribution of the agent in the surgical specimen so that a surgeon can be guided by the image provided by the apparatus, said apparatus connected to said detector.
Claims10
A method for near real-time determination of the presence and distribution of cancerous, precancerous or abnormal cells in a tissue specimen of a subject comprising the steps of:
- administering an agent to the subject, the agent concentrating in the cancerous, precancerous or abnormal cells;
- excising a sample of the tissue from the subject;
- slicing the sample to prepare sections of the sample;
- arranging the sections on a specimen holder;
- sealing the specimen holder;
- and
- imaging the sections with a receptor sensitive to the agent, the receptor being in close proximity to the sections, to identify the presence and distribution of cancerous, precancerous or abnormal cells within the sections.
