\paragraph*{Usage}
The declipseSPECT system is a freehand SPECT system, which means that radioactive tracers are injected into the patient and the radiation is meassured with a gamma probe. The advantage of declipseSPECT is that it tracks the patient and the probe and can compute a 3D reconstruction of the radiation.
Freehand SPECT systems are mainly used for lymphatic mapping in sentinel lymph node biopsy, especially for breast cancer. Intra-operative 3D imaging has many clinical benefits: it allows for localization of SLN and minimally invasive access, less training efforts (the procedure is very complex without visualization), quality control, automated documentation. This results in less morbidity, a shortened operation length and therefore reduced procedure costs.

-When using the the declipseSPECT system, the surgeon needs to look at the screen to be able to see the radioactive hotspots. At the same time he needs to see the patient to properly navigate the probe. This could lead to difficulties because he either needs to continuously switch between looking at the patient and the screen or try to navigate the probe while looking at the screen which shows the scenery from the tracking cameras' point of view, which might lead to issues with hand-eye coordination.

This could lead to difficulties because he either needs to continuously switch between looking at the patient and the screen or try to navigate the probe while looking at the screen, which shows the scenery from the tracking cameras' point of view, which might lead to issues with hand-eye coordination. An example is shown in \refFigure{declipseSPECT-OR}.
In this paper we introduce an addition to the declipseSPECT system that tries to solve this problem.
\subsection{Approach}
-%Visualization of acquired radiation data directly on a display attached to the probe.
Our approach is to visualize the important data from the terminal screen on a screen attached to the probe, so that the data is always in the surgeon's field of view.
