Leltek LU710LH

Thyroid and breast examinations suit the LU710LH's focus on superficial anatomy. Its 4.0–17.0 MHz linear array performs the scan, with dedicated presets setting the initial imaging parameters for these organs. B-mode presents tissue structure, and depth and gain controls shape the displayed field. Callipers and annotations add dimensions and examination context to selected frames, creating images you can revisit in the saved patient study.

In musculoskeletal work, the probe supports imaging of conventional and superficial structures, as well as nerve examinations. A live view follows the area beneath the transducer as you move it. The scanner also supports freehand needle and catheter guidance. Freezing a frame creates a measurement point, while cine review retains the surrounding sequence and helps document observations made during the scan.

Peripheral vessel and carotid assessment draw on anatomical imaging and optional Doppler functions. Colour Doppler maps flow within a selected area; power Doppler displays flow signals, and pulsed wave Doppler supports velocity assessment. These views can be recorded alongside the greyscale examination. The app stores images and clips under the patient study, with optional DICOM functions supporting transfer to a compatible clinical archive.

The Aesthetic preset addresses superficial imaging in aesthetic practice, and a dedicated Ocular preset supports ophthalmic examinations. Qualified healthcare professionals use these functions within clinical facilities. Weighing 345 g, the scanner has its own battery and communicates with a compatible phone, tablet, or computer at the examination location. Its diagnostic applications also include paediatric, neonatal cephalic, pulmonary and general abdominal imaging, with recorded frames available for measurement and reporting.

A defined role in superficial examinations

The array's frequency bandwidth reaches 17.0 MHz, supporting the LU710LH's focus on superficial anatomy. Breast, thyroid, peripheral vessel and musculoskeletal examinations fall within that role. Frequency selection works with the depth and brightness controls to set the view around the tissue under examination. The same imaging head supports both anatomical views and measurements on a retained frame.

A preset for aesthetic tissue imaging

The Aesthetic preset provides a starting configuration for superficial tissue imaging in aesthetic practice. It sits alongside breast, thyroid, vascular and musculoskeletal applications in the app. The operator can adjust the displayed field and image parameters within the selected examination. Saved views, annotations and measurements then record the anatomy examined, giving the preset a defined diagnostic imaging function.

Depth adjusted around the anatomical target

An imaging depth of up to 12.6 cm allows the displayed field to include a selected structure and surrounding tissue. The depth scale provides a spatial reference, while frequency selection changes the transmitted ultrasound settings. These controls support examinations centred on small organs or superficial soft tissue, where the location and extent of the recorded view both matter.

Brightness control throughout the image

Overall gain changes the brightness of the ultrasound picture, and time gain compensation adjusts brightness at selected depths. Dynamic range determines how the system represents returning echo strengths as shades of grey. Together, these controls let the operator set the appearance of the tissue image during scanning. Their effects remain visible on the paired display as the probe position changes.

Dimensional information attached to tissue views

Distance callipers measure the distance between chosen points on a frozen image. Ellipse tools add area and perimeter values for an outlined structure. The app retains measurement information with selected views for examination reporting. This joins the observed anatomy to the dimensions recorded by the operator, with annotations providing the location and descriptive context of the measured image.

Optional flow assessment within the anatomical field

Colour, power and pulsed wave Doppler are available as optional imaging functions. Colour and power modes place flow information in a selected part of the tissue view, while pulsed wave Doppler produces a velocity trace from a sample region. The operator can therefore examine anatomy and flow in a single study. Gain, sampling and display controls shape the recorded flow information.

A handheld probe with a separate viewing screen

Weighing 345 g including its battery, the imaging component fits in the operator's hand. Its Wi-Fi link sends the scan to a compatible display running the ultrasound app. Leltek specifies Android, iOS and Windows compatibility. This arrangement lets the probe contact the examination site while the screen sits in a comfortable viewing position beside the couch or bed.

Recorded views available for detailed review

The app stores still images and clips within an examination, preserving the selected views after live scanning has finished. Cine review also provides access to a 200-frame sequence for frame selection. Reports can combine images, measurements, annotations and patient details. Optional DICOM adds file exchange and server transfer when the examination is recorded in a compatible imaging archive.

Reusable equipment with defined routine care

The probe combines a rechargeable battery with a surface reprocessing method for intact-skin examinations. Cleaning is followed by low-level disinfection using 70% isopropyl alcohol. USB micro-B charging restores the battery between sessions, and an optional compatible dock provides a charging position. These upkeep tasks support the scanner's repeated use within a professional healthcare department.

4.0–17.0 MHz linear imaging

The LU710LH uses a linear array with 128 elements and an operating band from 4.0 to 17.0 MHz. That upper frequency supports imaging of fine superficial anatomy. The maximum imaging depth is 12.6 cm, and the app lets you select frequency and depth. These controls place superficial and small-organ examinations within the probe's defined acoustic range.

Presets for superficial and small-organ examinations

Application presets include Aesthetic, Thyroid, Breast, Superficial, MSK, Peripheral Vessels, Carotid, Ocular and Nerves. MSK denotes musculoskeletal imaging, including examination of muscles and tendons. The Aesthetic setting provides a starting configuration for ultrasound assessment in aesthetic practice. Settings can then be adjusted for the examination. Custom presets store selected parameters, providing a saved starting point for recurring scans.

Greyscale anatomy and motion recording

Brightness mode, or B mode, displays anatomy through the intensity of returning echoes. The greyscale image establishes the view used to locate structures and place measurements. Motion mode, or M mode, tracks echo movement along a selected line and displays changes over time. Both are standard functions, with the line position linked to the anatomical image during motion assessment.

Depth and brightness adjustment

The depth control selects the tissue depth displayed, while gain sets overall brightness. Time gain compensation adjusts brightness through successive depths, accounting for changes in echo strength along the image. Dynamic range and greyscale mapping govern how those signals appear as tones. The B-mode display uses 256 shades of grey, with image settings available during the live examination.

Harmonic imaging and frame processing

Tissue harmonic imaging builds its picture from echoes at multiples of the transmitted frequency. Persistence averages consecutive frames to control how movement and image variation appear. Scan-line density adjusts the number of lines forming each image. Frame-rate settings control how many images the app displays each second, with energy-saving, normal, and high-performance selections.

Optional colour and power flow imaging

Colour Doppler is an optional function that overlays blood flow information on the tissue view. The display represents flow direction and velocity inside an adjustable region. Optional power Doppler depicts the strength of the received flow signal. Each mode shows flow relative to the surrounding anatomy, supporting assessment of vessels and vascularity within the soft tissues being examined.

Optional pulsed wave sampling

Optional pulsed wave mode measures flow velocity at a selected site and displays a waveform over time. An adjustable sample gate defines the sampled region's location and extent. Angle correction, baseline and gain controls support trace adjustment. The anatomical image locates the sampling site, while the waveform records the changing flow velocity through that region.

Callipers and automatic measurement tools

Distance callipers mark two points on a frozen view and calculate the separation between them. An ellipse measures an outlined area and its perimeter. The app also includes automatic measurement tools. You can include measurement values in the examination report with selected images, keeping a clear link between the recorded dimension and the structure used to obtain it.

Handheld housing with physical controls

The probe measures 187 × 74 × 40 mm and weighs 345 g with its battery. The power and freeze buttons sit on the housing, putting operation and image freezing within the scanning hand. Status lights indicate power and wireless connection. A fan outlet dissipates heat, while the compatible display shows the live ultrasound view and the remaining examination controls.

Wireless connection to the LeSONO app

A compatible phone, tablet or computer runs the LeSONO app as the scanner's display and control interface. Leltek supports Android, iOS and Windows platforms. Image communication uses IEEE 802.11 a/b/g/n Wi-Fi across 2.4 and 5 GHz bands. The probe and viewing device form the examination setup, with the app displaying incoming images and organising the views saved during each examination.

Cine review of 200 captured frames

A frozen scan retains the preceding 200 frames for cine review, allowing you to move through the captured sequence. A selected frame can become a saved image. Video creation uses the same buffered sequence, with three seconds as the default clip length. The duration control selects how much of that sequence is recorded, preserving a chosen interval from the examination.

Annotated records and image export

Text notes, arrows and body marks add location and observation details to captured images. The app groups these views and videos under the patient study. Stills export as JPEG, PNG or BMP files, and video uses MP4. A PDF report brings together patient information, selected images, measurement details, annotations, a signature, and a date, creating an examination record.

Optional DICOM study exchange

The DICOM 3.0 option adds medical image export and transfer between the app and a configured image server. DICOM files retain study information with the image. Worklist support brings examination details into the scanning application, and server settings define the receiving connection. These functions support moving captured views from the probe's app to a compatible imaging archive.

Battery operation and micro-B charging

A rechargeable 6000 mAh lithium-ion battery powers the transducer. Approximate continuous use reaches 4.5 hours in B or M mode, 3.5 hours in colour or power Doppler, and 2.5 hours in pulsed wave Doppler. The micro-B USB connection handles charging at up to 15 W and cable data transfer. Its battery rating covers 300 discharge cycles.

Surface reprocessing for repeated examinations

The acoustic window works with ultrasound gel to maintain sound transmission at the skin. After intact-skin examinations, the probe undergoes cleaning and low-level disinfection with 70% isopropyl alcohol. The housing and scanning face are part of this surface-care routine. The transducer can then return to repeated clinical use, with its battery recharged between scanning periods.

App updates and warranty options

Leltek provides the LU710LH with app updates and a one-year manufacturer warranty. Optional extended warranty coverage is available. The app update function maintains the software used to control scanning and manage saved examinations.

The LU710LH suits clinical teams whose work centres on superficial anatomy and small-organ examinations. Breast and thyroid imaging, musculoskeletal assessment and superficial tissue imaging in aesthetic practice give its high-frequency linear array a defined purpose. Its controls let you adjust the displayed field and tissue brightness around the selected anatomy, while retaining measurements on saved views. Optional Doppler extends that role to flow assessment, while optional DICOM connects the recorded examination with compatible imaging archives. The daily setup pairs the scanner with a supported display and includes battery charging and intact-skin reprocessing. The probe weighs 345 g with its integrated battery.
