Sierra NMUS1™ Integrated Ultrasound

Sierra NMUS1™

Point‑of‑Care Neuromuscular & MSK Imaging—Seamlessly Embedded in Sierra Summit

The Sierra NMUS1 turns your Sierra Summit electro‑diagnostic cart into a full neuromuscular‑ultrasound workstation. One button swaps from EMG or NCS to real‑time B‑mode, colour flow or Doppler imaging; captured stills and video clips drop straight into the same report—so physicians hear, see and stimulate within a single protocol.

Key Features
  • Ultrasound & Electrodiagnostics in One Workflow: Instant modality switch from EMG/NCS to imaging—no cables to swap or software to relaunch. NMUS+™ protocol shares Sierra’s look‑and‑feel, auto‑labels structures, and quantifies tissue with Q‑Mode™ analysis. Unified reporting combines traces, numbers and ultrasound images in a single PDF or HL7 export.
  • High‑Performance Imaging Engine: Variable transmit frequencies 2 – 18 MHz; eight simultaneous beamformers for fluid B‑mode, four for colour flow. Advanced processing: Spatial Compounding, Edge & Speckle Reduction (basic + advanced), Harmonic Scanning, Trapezoid View, Algo8™ clarity. Zoom from 1:1 to 30:1 (live or frozen); 10‑second cine loop with frame‑by‑frame review.
Technical Specifications
L14‑4 Linear (standard) Frequency Range: 4 – 14 MHz (16 MHz max), Elements / Pitch: 192 / 0.20 mm, Footprint: 38.4 mm, Typical Use: General nerve & muscle imaging, injections
HL18‑4 Hockey‑Stick Frequency Range: 4 – 18 MHz (20 MHz max), Elements / Pitch: 128 / 0.20 mm, Footprint: 25.6 mm, Typical Use: Small nerves, digits, paediatric, intra‑operative
C5‑2 Curvilinear Frequency Range: 2 – 5 MHz (6 MHz max), Elements / Pitch: 160 / 0.38 mm, Footprint: 70° FOV, Typical Use: Deeper muscles, pelvis, abdomen
Integrated Controls & Needle Guidance Adjust depth, gain, Doppler, freeze, save and annotate from the Sierra Summit base unit or StimTroller Plus. Side‑by‑side trace + image view aids precise needle placement for chemodenervation or pain injections.
Why Choose Sierra NMUS1?
  • : One‑station efficiency – finish a full EMG / NCS / ultrasound exam without moving the patient or juggling software.
  • : High‑resolution imaging – up to 18 MHz with advanced clarity algorithms reveals fascicles, entrapments, muscle texture and needle tips.
  • : Versatile probe set – linear, hockey‑stick and curvilinear transducers cover superficial fingers to deep gluteal muscles.
  • : Smart analytics – Q‑Mode quantifies tissue brightness for objective follow-up of myopathies and neuropathies.
  • : Future‑proof platform – firmware updates arrive through Sierra software; add new probes or protocols as NMUS grows.

Sierra NMUS1 gives electro‑diagnostic clinicians the power of ultrasound exactly where they need it—inside the workflow they already know—delivering faster exams, richer data, and greater diagnostic confidence at the point of care.
