Operation instrument for examining object - copes with e.g. biopsy tube with detection by NMR process

Abstract

Abstract As an alternative the NMR active nuclei near the active part of an object under examination transmit NMR signals in conjunction with a NMR or magnetic resonance test reprodn. unit. The NMR active nuclei are arranged also in an interaction with a substance, namely, a relaxant which causes the activation of a NMR signal by means of dynamic nuclear polarisation (DNP), if the electron spin system of the above substances is saturated with external energy esp.saturation energy. The active part of the operation instrument contains a substance which has NMR active nuclei and a relaxant for the prodn. of a DNP phenomenon. USE/ADVANTAGE - Operation instrument for examination of object e.g human body animal body, food or tree trunks and simultaneous control. Controls absorption and penetration of radiation to prevent overheating and possible adverse effects.
