The only integrated system for radio-guided surgery with gamma imaging and optical fusion in real time.

Sentinella is an innovative system for sentinel lymph node detection in the operating room, fusing the gamma image with an optical image in real time. This fusion between gamma image and optical vision allows very intuitively positioning the gamma camera in the area of interest for the detection and subsequent excision of the sentinel node, evaluating, in addition, possible extensions to the lymph nodes, even if they are outside the conventional lymph node chain.

Sentinella is 100% portable. It includes an ergonomic arm with a positioning laser that allows the camera to be placed in hard-to-reach areas. The camera’s high resolution is ideal for minimally invasive surgeries. Also, its dedicated Sentinella Software Suite offers multiple applications to obtain more information and benefit from the images: virtual lead, ROIs, dual tracer, radioactive pointer marker (as I125 seeds), dynamic and sequential images. Sentinella Horus is also compatible with Worklist and PACS systems, being integrated in the software Suite by uploading all the information in compatible and DICOM formats.


Allows for more intuitive system operation and faster camera positioning, facilitating safe and accurate sentinel node detection and removal.

Able to identify nodes not detected with other radioguided surgery techniques, thus avoiding re-interventions or new procedures. 

Suitable for any clinical application where the sentinel node technique is performed.

The gamma camera, with exclusive technology developed by Oncovision, generates high-resolution images that, when fused with the optical image, allows to visualize with great clarity even the most difficult to locate nodes.

A “clean field” acquisition ensures the removal of radiotracer-labeled nodes. Sentinella also has a series of software tools capable of taking the practice of radioguided surgery to a new level. It is easy to use, even in the sterile field, and provides high quality images, as well as comparative imaging and quantification of activity before and after sentinel node removal. 


Sentinel Lymph Node Biopsy is the most important prognostic factor in defining the treatment and clinical evolution of patients, so detecting it safely has a great impact on patient prognosis. Sentinella has been used in thousands of surgeries and has been extensively tested with evidence of high clinical reliability in applications such as breast cancer, melanoma, head and neck tumors (especially thyroid and parathyroid pathologies), and as a complementary technique to other detection techniques in urological and gynecological cancers as well as in techniques such as ROLL, SNOLL and lesion localization with LDRS.
