Wireless Ultrasound for Vascular Access
See the vein.See the needle.
IVScanner™ brings wireless ultrasound and ASUS Needle Enhance technology to the bedside, helping trained clinicians visualize the target vessel and advancing needle during ultrasound-guided vascular access.

The Complete Solution
Not just a probe.A focused access workflow.
IVScanner brings together the elements needed to evaluate and implement ultrasound-guided peripheral IV access: technology, clinical workflow, and a plan for training.
Wireless Imaging Technology
ASUS LU800L linear ultrasound supports peripheral-vessel imaging and freehand needle/catheter interventional guidance, without a traditional tethered probe.
Enhanced Needle Visualization
ASUS Needle Enhance includes adjustable Needle Angle and Needle Gain controls to support needle visualization during ultrasound-guided procedures.
Focused Implementation
An approach to role definition, hands-on learning, and competency-based adoption that can be aligned with each organization’s policies and clinical resources.
The Distinguishing Feature
Find the vessel.Follow the needle.
Finding a vein is only part of the procedure. During ultrasound-guided access, clinicians also need to distinguish the advancing needle from the surrounding anatomy.
- Needle Enhance helps identify the needle and continually removes anatomical reflection artifacts.
- Needle Angle sets the beam perpendicular to the needle’s path.
- Voice control switches Needle Enhance on hands-free.
Needle Gain
How It Works
A clear path from difficult access to guided placement.
IVScanner is designed around a simple, clinician-directed workflow. Procedures are performed by appropriately trained staff within institutional protocols and scope of practice.
- 1
Assess
Identify patients who may benefit from ultrasound-guided peripheral IV access.
- 2
Visualize
Use the linear probe to evaluate candidate vessels and surrounding anatomy.
- 3
Guide
Use real-time ultrasound and appropriate settings to guide needle advancement.
- 4
Complete
Confirm and document access according to facility policy and standard clinical practice.
Where It Can Fit
Put vascular access imaging where the patient is.
IVScanner starts with the workflow challenge of patients whose veins are difficult to access using traditional palpation or visualization alone.
Whether a team is building ultrasound-guided peripheral IV capability or expanding access beyond a specialized team, the goal is practical bedside readiness, not another general-purpose ultrasound system to figure out.
Focus the technology on one repeatable procedure, then build the clinical competency around it.
Discuss Your SettingThe Published Evidence
Why ultrasound guidance matters.
Independent research supports ultrasound-guided peripheral IV cannulation for patients with difficult intravenous access. These findings support the technique; they are not IVScanner-specific performance claims.
Systematic Review and Meta-AnalysisUltrasound-Guided Peripheral IV Cannulation vs the Landmark TechniqueAnderssen et al. · The Journal of Vascular Access · Online 2025.Read the study ↗︎
8 RCTs
1,477 emergency-department patients
Included in the systematic review. The first-attempt success meta-analysis used 940 of those patients.
24 RCTs
8,014 participants, 11 interventions
A 2026 network meta-analysis found ultrasound guidance improved first-attempt and overall success in adults with difficult IV access compared with standard practice.
Important distinction: These studies evaluate ultrasound-guided access in general, not ASUS Needle Enhance or IVScanner. Benefits depend on patient selection, training, and technique.

↗︎Frequently Asked Questions
A Focused POCUS Solution.Practical answers.
For clinical leaders considering an ultrasound-guided IV access workflow.
Is IVScanner a vein finder or an ultrasound system?
IVScanner is a focused vascular-access solution based on ASUS wireless ultrasound. Unlike infrared vein visualization, ultrasound displays subsurface anatomy and supports real-time guidance during the procedure.
What is ASUS Needle Enhance?
ASUS lists Needle Enhance as an imaging function with Needle Angle and Needle Gain controls. It is intended to support needle visualization; it should not be confused with automated needle-tip tracking or a guarantee of successful cannulation.
Who can perform ultrasound-guided IV placement?
Appropriately trained, credentialed, or authorized healthcare professionals operating within their scope of practice and organizational policies. Training and competencies should be established before clinical use.
Does the IVScanner probe support more than peripheral IV access?
Yes. The ASUS LU800L's FDA-cleared uses are general abdominal imaging, pediatric, small organ (thyroid, prostate, scrotum, breast), neonatal cephalic, musculoskeletal (conventional), musculoskeletal (superficial), peripheral vessel, carotid, pulmonary, and interventional guidance (free-hand needle/catheter). IVScanner focuses the probe on ultrasound-guided peripheral IV access.
Does Needle Enhance improve first-attempt success rates?
Clinical literature supports ultrasound guidance for difficult peripheral IV access, but we have not identified device-specific trials measuring the added effect of the ASUS Needle Enhance function. We do not make a quantified success claim for this feature.

Intended for healthcare professionals. Ultrasound imaging and guided procedures must be performed by qualified and trained clinicians using aseptic technique, device labeling, and institutional protocols. The ASUS LU800 series FDA 510(k) clearance (K250791) is for the ASUS ultrasound device; this page does not claim a separate FDA clearance for IVScanner.
Scientific findings cited are for ultrasound-guided intravenous access generally, not clinical validation of IVScanner or the ASUS Needle Enhance feature.
