Leltek LU700L

The LU700L serves professional healthcare settings where clinicians examine superficial anatomy or use live imaging to guide freehand needle and catheter placement. Its 5–10 MHz linear array provides imaging depth up to 6 cm. Ultrasound-trained physicians and other qualified healthcare professionals can use that window to view the tissue of interest alongside nearby vessels, nerves and soft structures.

In musculoskeletal clinics, the scanner supports conventional and superficial examinations of muscles, tendons and other soft tissues. The MSK and Superficial presets provide starting configurations for these views. Nerve imaging has its own preset, supporting examinations where the relationship between a nerve and surrounding tissue is part of the assessment.

Vascular work includes peripheral vessels and carotid imaging. Optional colour and power Doppler add blood-flow displays, while optional pulsed wave Doppler provides a velocity trace from the selected sample region. Together, these features extend the information available from a B-mode view during a vascular study.

Small-organ applications include the thyroid, breast, prostate and scrotum within the probe's imaging range. Dedicated Thyroid and Breast presets support two of those examination groups. The indicated scope also includes paediatric, neonatal cephalic, pulmonary and general abdominal imaging where the target anatomy lies within the available 6 cm depth.

The handheld probe can move between examination rooms, procedure rooms, and hospital wards, and it has a manufacturer-compatible display. Saved images, measurements, and annotations retain examination details, while the 200-frame cine buffer supports review of recent scans. Cleaning followed by low-level disinfection forms part of its routine use between intact-skin examinations.

Live anatomy during freehand guidance

The LU700L supports freehand needle and catheter guidance through its live linear image. It covers peripheral vessels, nerves, and superficial musculoskeletal structures. The clinician positions the probe to obtain the view used during the procedure, with the companion app displaying the image. Depth and gain remain adjustable while the examination is in progress.

Imaging settings matched to the target

Across the 5.0–10.0 MHz band, frequency selection works alongside depth and gain to shape the displayed anatomy. Time gain compensation adjusts brightness at different depths. This gives the clinician separate controls for the overall view and the appearance of structures within it. The scan can be adjusted around a superficial target within the 6 cm imaging range.

Presets for vessels, nerves and small organs

Peripheral Vessels, Nerves, MSK, Thyroid and Breast presets provide starting settings for their respective examinations. Carotid and Superficial selections are also available. After selecting a preset, the app lets you change individual parameters, and custom presets can retain your chosen configuration.

Anatomical context for optional flow assessment

Optional colour Doppler places flow information within a selected region of the anatomical view. Power Doppler is another optional display that represents the strength of the detected flow signal. For velocity tracing, optional pulsed wave Doppler samples from a chosen position. The B-mode image remains the anatomical reference.

Measurement on a retained image

After acquisition is frozen, the cine sequence provides frames you can select for measurement. The distance and ellipse tools work on the displayed anatomy, and the app retains the calculated values in the study. The app includes an automatic measurement tool. You can also add arrows, text, and body marks to the selected frame to identify the location of the recorded finding.

Images and notes associated with the study

Patient study records hold the examination's selected stills and clips. A PDF report can combine those views with measurements, annotations, a signature and date. Optional DICOM functions also support image export, server upload and retrieval of examination entries through a worklist.

Display position separate from probe handling

Leltek specifies compatible Android and iOS mobile devices and Windows computers for viewing and controlling the scan. The direct Wi-Fi link carries image data between the probe and that device. The display can therefore be placed for viewing while the clinician handles the transducer at the patient. A physical freeze button remains accessible on the handpiece.

Rechargeable power with a stated charging period

The scanner's integrated lithium-ion battery has a 6000 mAh capacity. Full charging takes approximately 3–4 hours with a 5 V, 2 A supply. Mode-dependent endurance includes up to 30 minutes of use and 10 minutes of rest per operating cycle.

Surface care for repeated skin-contact use

Routine intact-skin examinations use compatible coupling gel, followed by cleaning and low-level disinfection. Leltek specifies 70% isopropyl alcohol for the probe, and cleaning also occurs before use. The housing and scanning surface remain part of this care process.

Linear Array for Superficial Anatomy

A 128-element linear array forms the LU700L's imaging surface. Its 5.0–10.0 MHz bandwidth and 6 cm maximum depth define the field available for superficial tissue assessment and procedural guidance. Frequency and depth are adjustable within that range. This combination gives the examination a focused scale for viewing vessels, nerves, tendons and other structures close to the skin.

Standard B and M Imaging

B-mode supplies a two-dimensional view of tissue using 256 shades of grey. M-mode records movement along a selected line over time, adding a temporal trace to the anatomical view. Both modes are part of the standard configuration. You can freeze the live image for examination, with full-screen viewing available during scanning, image review, and inspection of stored records.

Presets for Defined Examination Areas

Leltek provides Peripheral Vessels, Thyroid, Breast, Superficial, MSK, Carotid and Nerves presets for the LU700L. Each preset supplies an application-specific starting point for imaging. Adjustable parameters remain available during the examination, and custom presets preserve a user's selected settings. This gives repeated examinations a consistent starting configuration while retaining control over the image presented to each patient.

Control of Image Brightness and Detail

During live imaging, gain controls overall brightness, and time gain compensation adjusts brightness at different depths. Dynamic range and grey maps shape echo display, while persistence smooths changes between successive frames. Tissue harmonic imaging, enhancement and line density provide further image controls. Energy saving, normal, and high performance settings let you select the frame-rate operating profile.

Optional Blood Flow Modes

Optional colour Doppler places directional flow information over the B-mode image within an adjustable region. Power Doppler displays flow signal strength, and pulsed wave Doppler samples velocity at a selected location. Controls include colour gain, pulse repetition frequency and the sampling parameters used with pulsed wave imaging.

Direct Wireless Display Connection

The probe connects directly to a manufacturer-compatible smartphone, tablet or computer running the companion ultrasound app. Android, iOS and Windows platforms are supported, with iOS 15 or later required for the current iOS app. Communication uses IEEE 802.11a/b/g/n across 2.4 GHz and 5 GHz bands. WPA2 authentication permits one connected display at a time for the examination.

USB Charging and Dock Option

USB supports recharging and a cable data link. A full charge takes about 3–4 hours with a 5 V, 2 A charger, and the charging input supports DC 5 V at up to 3 A. An optional compatible dock provides DC 5 V, 2 A output from an AC 100–240 V, 50/60 Hz supply.

Probe Controls Within a Compact Body

At 357 g including its battery, the LU700L measures 178 × 74 × 40 mm. The power and freeze buttons sit on the probe, putting those functions within reach of the scanning hand. A fan outlet dissipates heat. Status lights indicate power, Wi-Fi connection, charging, and low battery, and the charging light turns off when the battery reaches full charge.

Battery Capacity and Operating Cycle

A 6000 mAh rechargeable lithium-ion battery powers the scanner. Approximate endurance per charge is 4.5 hours in B-mode or M-mode, 3.5 hours with optional colour or power Doppler, and 2.5 hours with optional pulsed wave Doppler. Operation follows a cycle of up to 30 minutes of use followed by 10 minutes of rest. Battery life is specified at 300 discharge cycles.

Measurement Tools on Frozen Images

On a frozen image, distance tools measure a selected length and ellipse tools calculate area and perimeter. An automatic measurement tool is also included. Measurements can accompany images in the patient record and the exported report, preserving their relationship to the examined anatomy. Arrows and position marks identify the location associated with an observation or recorded measurement.

Review of the Latest 200 Frames

Freezing the scan makes the latest 200 frames available for review. The operator can return to an image within that sequence, annotate it and retain it as a still. A video can also be formed from the saved frames. Clip duration is adjustable and defaults to 3 seconds, providing a short record of the acquired sequence.

Patient Records and Image Annotation

Examination records associate still images and video clips with patient information in the app. Text notes and body marks add context to the stored view, while movable annotations keep the observation beside the relevant structure. Saved studies remain available through the review function. Batch management lets you select multiple stored items for export as you prepare the record.

Still Images, Video and PDF Reports

JPG, PNG, and BMP formats are available for still-image export, and MP4 is used for video clips. PDF reports collect patient information, selected images, measurements, annotations, a signature and a date in one document. This preserves both the visual finding and its recorded context. Image and video files can also be exported individually to local storage from the app.

Optional DICOM Study Exchange

With optional DICOM 3.0 enabled, the LU700L supports exporting and uploading images to a configured server. Worklist retrieval brings patient information into the examination workflow through the app's server settings. The same study can therefore move from patient selection to acquisition and DICOM transfer. Local image review and report generation remain available within the companion software.

Reusable Needle Guide Option

When a procedure calls for a supported needle path, a manufacturer-compatible reusable guide is available. The guide attaches to the probe and provides mechanical support for needle placement during tissue biopsy. Medical-grade, corrosion-resistant stainless steel forms the accessory. Its attachment combines that physical support with the LU700L's live linear image during the guided procedure.

Routine Care Between Examinations

Intact-skin use requires cleaning and low-level disinfection before and immediately after scanning. Leltek specifies 70% isopropyl alcohol for probe disinfection. Spray the agent onto the probe head, repeat the application 2 or 3 times, then wipe with a clean paper towel.

The LU700L suits professional teams that need live views of superficial structures during examination and freehand needle or catheter guidance. Its 6 cm depth defines a focused role in vascular, nerve, small-organ and musculoskeletal work. A separate compatible display lets you arrange the screen position around the procedure.

That role fits departments able to plan around a 3–4 hour charging period with a 5 V, 2 A supply and the stated cycle of use and rest. Cleaning followed by low-level disinfection is part of routine turnover after intact-skin examinations. Where flow assessment is part of the service, the available Doppler options extend the selected configuration. The handpiece weighs 357 g, including its battery.
