Abstract: A pre-operative device includes at least one elongated probe (1) integrating at least one element for detecting radioactive radiation (3) emitted by tissues (4) marked by radioactive isotopes or radioactive colloids, generating a first representative electrical signal (5), at least one element (6) for emitting luminous radiation toward the tissues (4) and at least one element (7) for receiving and transmitting reflected luminous radiation (8) reflected by the tissues (4) marked by vital colorants or magnetic markers, toward at least one element (9) for converting the reflected luminous radiation (8) into a second representative electrical signal (10), electrical connection elements for conveying the first and second electrical signals (5, 10) and, at least one electronic means (11) for processing electronic signals.

Abstract: The present invention relates to a process and installation for simultaneously measuring the flux of ionizing radiation, of an energy greater than several kVe and the dose of radiation received by a body exposed to this radiation.

Abstract: The present invention has for its object a pre-operative device particularly for the location of tumors and a detection process using said device.
