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.

Standard Lymphatic Mapping Probe

Tip Diameter: 14 mm
Shaft Length: 67 mm
Tip Angle: 35°
Shielding: High-energy Tungsten
Collimation: Internal, retrograde
Energy Range: Up to 364 keV

RMD's most popular probe for lymphatic mapping of malignant melanoma and breast cancer.

Straight Lymphatic Mapping Probe

Tip Diameter: 14 mm
Shaft Length: 67 mm
Tip Angle: 0°
Shielding: High-energy Tungsten
Collimation: Internal, retrograde
Energy Range: Up to 364 keV

Same high specificity as angled 14 mm probe, for those who prefer a straight tip probe.

Superficial Head and Neck Probe

Tip Diameter: 11 mm
Shaft Length: 53 mm
Tip Angle: 0°
Shielding: High-energy Tungsten
Collimation: Internal, forward
Energy Range: Up to 364 keV

Has been applied to hyper-parathyroid localization.

Thoracic Probe

Tip Diameter: 10 mm
Shaft Length: 190 mm
Tip Angle: 0°
Shielding: High-energy Tungsten
Collimation: Internal, forward
Energy Range: Up to 364 keV

Intermediate shaft length.

Abdominal Probe

Tip Diameter: 10 mm
Shaft Length: 310 mm
Tip Angle: 0°
Shielding: High-energy Tungsten
Collimation: Internal, forward
Energy Range: Up to 364 keV

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.

Daniel Probe                                                                                                                              NEW!

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 E097015. The Daniel Probe is RMD order code E097620.
