Navigator Probes
Probe Design and Applications
RMD probes are designed for excellence in the detection of the gamma signal. Before
their placement in the probe tip, the detectors in RMD's probes are selected for energy
resolution and sensitivity to gamma photons. Shielding inside the probe tip eliminates
the detection of gamma rays proceeding from outside the probe's field of view.
Collimation sealed inside the tip defines the probe's field of view. RMD's probe size and shape are refined for specific applications.
Each of the above gamma probes is compatible with the Navigator™ control unit manufactured by RMD. Navigator™ is a trade name used in the United States by RMD Instruments Corp of Watertown, MA. An RMD-manufactured control unit may be identified by a serial number tag with the manufacturer's name "RMD" of "Watertown, MA". RMD manufacturers and sells a re-usable probe cable specific to the Navigator™ GPS control unit. The above probes are designed, manufactured, sold, and serviced by RMD Instruments, of Watertown, MA.
Navigator™ Gamma-PET probe detects the 511 keV photons that proceed from tissue tagged with PET pharmaceuticals such as 18F-FDG.
The Navigator Gamma-PET probe is shown below with the new Navigator GPS control unit that shows the selected isotope.

Navigator™ Gamma-PET probe system consists of the probe, cable and module.
The Navigator gamma-PET probe system is RMD order code SP-3045-00. The module connects directly to the Navigator™ GPS control unit.

The NEW 12mm SMX Probe uses Scintillation Crystal Photomultiplier technology for improved performance and
double the sensitivity of Cadmium Telluride probes. This increased sensitivity is particularly important for
procedures involving patients with greater tissue density, previous surgery, atrophied lymphatic pathways from age,
or lower doses of Tc99. The 12mm SMX Probe has a narrower probe tip, which allows for a smaller incision,
while also providing superior specificity, to more accurately delineate tumor margin.
Like the Gamma-PET Probe, the 12mm SMX Probe assembly consists of the probe, cable, and Gain Module.

The Daniel probe may be used by thoracic surgeons in a video-assisted biopsy of sub-centimeter lung nodules labeled
with tc-99m and previously identified by standard methodologies.
The Daniel probe is shown here with the New Navigator GPS Control unit and is used with the standard Navigator GPS probe cable.
The cable is RMD order code GP-4001-00. The Daniel Probe is RMD order code SP-2S10-31D.
