Seracam (hybrid gamma optical camera) is for investigational use only and has not been cleared or approved by the FDA or UK and European regulatory authorities.
A hybrid gamma optical camera
Like all gamma cameras, Seracam is used to form images revealing the distribution of a radiopharmaceutical that has been administered to a patient in order to help in the diagnosis or monitoring of disease. Seracam uses a microcolumnar CsI(Tl) crystal scintillator to convert gamma photons to optical photons that are detected by a semi-conductor. Incoming gamma rays are collimated by a pinhole collimator in order to preserve image resolution, and Seracam includes four different pinholes that can be automatically selected to optimise the balance of image resolution and speed of image acquisition for the case at hand. An in-built optical detector with the same field of view, independent of imaging distance or angle, means that optical and gamma images can be overlaid with no parallax and with real-time image streaming to the control PC.
All this is packaged into a self-shielded camera head of 6 inch / 15cm diameter weighing less than 5kg (about 10 pounds), mounted on a fully articulated arm for easy positioning and a wheel base that allows a single operator to transfer the system along corridors, through doorways and in elevators to any location within a hospital. A single cable connection enables plug-and-play operation for rapid installation and set up.
Seracam is suitable for use with all commonly used isotopes for gamma imaging such as 99mTc, 123I, 111In (energy range 50-250 keV).
