Intraoperative probe for detection of tumour residues<\/h1>\n

By making it easier to identify any residues, the use of the device contributes to the better success of surgical procedures for removing tumour masses.[\/vc_column_text][vc_empty_space][vc_single_image image=”4349″ img_size=”full” qode_css_animation=””][vc_empty_space][vc_column_text]<\/p>\n

How does it work?<\/span><\/h3>\n

[\/vc_column_text][vc_empty_space][vc_column_text]Beta-emitting radionuclides, when passing through biological tissue, release their energy in 2-10 mm. This feature of low penetration (short range) allows the detection of tumour residues exclusively in the immediate vicinity of the tumours themselves. In order to detect any residues at a greater distance, it is also of interest to detect the secondary radiation of bremsstrahlung, emitted by beta particles, which is able to penetrate for several centimetres although it is not very intense. <\/p>\n

The intraoperative probe that is the subject-matter of the invention detects radiopharmaceuticals based on beta-emitting radionuclides, and thus the tumour residues to which they are bound, and consists of two selective sensors one for bremsstrahlung radiation (X-rays, 10-100 keV) for spatial detection per centimetre (1-10 cm), the other for subsequent point detection, sensitive to primary (beta) radiation.[\/vc_column_text][vc_empty_space][vc_column_text]<\/p>\n
