Supporting radio-guided surgery through intraoperative 3D imaging and navigation
declipse®SPECT is designed for seamless integration into the surgical workflow. It is based upon existing gamma probes and thus does not interfering with their current usage. It provides images at the time of surgery and thus precise localization of the structures that need to be resected.
The system is positioned next to the operating room table and its portable cart allows flexible positioning without interference of other instruments. The intuitive user interface that is controlled by a large image viewing touch screen monitor enables direct mapping, easy access and resection control during SLNB in breast, melanoma and head & neck as well as in the ROLL and RSL technique with a seamless integration in the clinical workflow.












declipse®SPECT is a SPECT imaging device based on a handheld gamma probe reported as freehandSPECT imaging in the literature [Wendler2010]. In contrast to traditional SPECT imaging solutions, declipse®SPECT does not rely on a gantry mounted gamma camera rotating around the patient, but a handheld gamma probe extended by a 3-D tracking system. A scan of 1-2min around the patient from anterior-posterior and lateral directions enables a 3-D reconstruction of the radioactive distribution in the target region with a spare set of projection data.
declipse®SPECT currently supports all low energy radionuclides. Tc99m, which is currently the most commonly used radionuclide for SLN imaging, is generating full 3-D images with a resolution of 5mm in all three dimensions as deep as 7cm from the surface.
An integrated video camera provides a direct correlation of the 3-D images projected onto the image plane. This provides gamma camera images from different viewpoints with direct anatomical correlation through overlay onto the optical image. This innovative technology of augmented reality enables direct referencing and visualization of the activity onto the real-time video of the patient. The advantage over standard monitor based image viewing is the direct overlay and anatomical correlation for intuitive orientation, localization and resection of radioactively marked structures. Thus any standard surgical instrument is guided to the region of interest without any modification.
