Leltek LU710PA

In cardiology departments, the LU710PA uses a 90° sector and imaging depth up to 30 cm to present adult cardiac views. Its 1.3–3.7 MHz phased array forms the scan, while the Cardiac preset supplies initial image settings. B mode displays anatomical structure, and M mode records motion along a chosen line. Cardiology auto-measurement and image callipers help document the selected view.

Paediatric cardiac assessment uses the handheld probe with settings adjusted to the examination. The image appears on a supported phone, tablet or computer positioned for the clinician's view. At 350 g, the battery-powered unit can be held at the examination site while the app presents the scan nearby. Optional colour, power and pulsed wave Doppler extend the configured system to flow assessment, including a velocity waveform from the selected sample. Frozen frames accept measurements, while retained clips preserve a sequence of movement for later review.

Hospital emergency departments can use the probe for FAST/EFAST and pulmonary examinations within its stated scope. It also supports general abdominal and fetal imaging, with an Abdomen preset for abdominal views. Depth and gain controls adjust the image around the structures under assessment. The physical freeze button pauses the live picture, and the cine buffer retains recent frames for selection during the examination.

Nerve and broader paediatric examinations extend the scanner's role in clinical facilities. Across these assessments, images and measurements remain associated with the patient study, with selected material available in a PDF examination report. Optional DICOM transfers record views to a compatible archive. Battery charging and cleaning, followed by low-level disinfection, are part of the routine upkeep for intact-skin examinations.

A cardiac sector with adjustable depth

The 90° field spreads from the phased array into the selected scan plane, and depth adjustment extends the displayed region to 30 cm. This gives cardiac assessment a defined imaging envelope. The clinician can position the probe around the acoustic window and set the image depth around the structures under examination. Frequency and gain controls then shape the appearance of returning echoes within that view.

Motion displayed along a chosen line

Moving heart structures can be examined spatially in B mode and across time in M mode. The M-mode line identifies where the motion trace originates within the anatomical picture. This relationship gives the recorded movement a visible location in the scan. A saved motion view can therefore represent both the selected tissue line and its movement during acquisition.

Cardiology tools beside the acquired view

Automatic cardiology measurements place dedicated tools within the same app used to acquire the ultrasound image. The cardiac preset supplies an initial imaging configuration, while the operator retains control of depth, gain and the selected view. Measurements and retained frames stay within the examination workflow. This connects the recorded cardiac anatomy with the dimensional information used during assessment and review.

A record that carries image context

Text, arrows and body marks give saved ultrasound views a written or visual reference to their location. Distance and ellipse tools add measurements directly to the chosen image. The resulting examination record can contain both the observed anatomy and the operator's markings. PDF reports bring selected findings together, while Leltek specifies optional DICOM export for transfer to a compatible imaging archive.

Display placement around the scanning position

Leltek specifies operation with compatible Android, iOS and Windows devices over Wi-Fi. The viewing screen can be positioned separately from the handheld probe, so its location can be arranged around the examination couch. The scanner weighs 350 g, including the battery. Power and freeze buttons on the housing let the operator control those functions while holding the imaging component.

Flow options with defined sampling

Colour Doppler adds flow information over a chosen image region, while power Doppler represents the strength of the detected Doppler signal. Both are optional. Optional pulsed wave Doppler samples a selected location and displays velocity over time. These modes add additional flow views to cardiac or abdominal examinations, with the sampling region and display controls set within the app.

A role in abdominal and acute assessment

The Abdomen preset places abdominal scanning alongside the cardiac configuration. In addition to its indicated uses, the probe also supports pulmonary imaging and FAST/EFAST, the focused ultrasound assessment used during trauma evaluation. Clinicians can acquire the relevant views and save images or clips within the patient study. This gives hospital teams a handheld imaging format for several defined assessment tasks.

Rechargeable power with a stated operating cycle

Battery endurance varies with imaging mode, from approximately 2.5 to 4.5 hours per charge. The specified operating cycle pairs up to 30 minutes of use with 10 minutes of rest. These figures separate charge endurance from each scanning period. USB charging restores the integrated battery, and a manufacturer-compatible charging dock is available as an option.

Surface care after intact-skin examinations

For examinations on intact skin, the phased array probe supports cleaning followed by low-level disinfection using 70% isopropyl alcohol. That process prepares its contact surfaces for subsequent use. The rechargeable scanner stays part of the reusable equipment in the examination room, with ultrasound gel providing acoustic contact during scanning. Surface care and battery charging form its routine between-use requirements.

Phased-array sector imaging

The LU710PA uses a 64-element phased array to steer ultrasound electronically. Its 90° sector spreads outward from the contact area, creating a widening view of deeper structures. This geometry underpins its cardiac and FAST applications. A 1.3–3.7 MHz frequency band and 30 cm maximum imaging depth give the operator a defined range for selecting the displayed field during adult and paediatric cardiac examinations.

Anatomy and motion in B-mode and M-mode

B-mode forms a two-dimensional greyscale view of the scanned anatomy. M-mode records changes along a selected ultrasound line over time, making movement visible as a trace. Both modes form part of the standard imaging configuration. During cardiac assessment, the anatomical image shows the selected line's position, while the motion trace shows how structures along that line move over successive moments.

Cardiac and abdominal presets

The two named examination presets are Cardiac and Abdomen. Each provides a starting set of imaging parameters for its application, and user-defined presets retain a chosen configuration for subsequent examinations. Depth, gain and other image controls remain adjustable within the scanning workflow. This combination lets a cardiac examination begin with an appropriate preset and continue with settings tailored to the view being acquired.

Optional Doppler modes

Colour Doppler, power Doppler and pulsed wave Doppler are optional imaging modes. Colour Doppler places flow information over the anatomical image, while power Doppler displays the strength of the Doppler signal. Pulsed wave Doppler samples velocity at a selected location. Adjustable sampling position, gate size and angle correction give the flow examination its own controls alongside the B-mode view and the available spectral display.

Measurements within the cardiac study

Cardiology automatic measurement tools sit alongside the app's general measuring functions. You can add distances, ellipse areas, and ellipse perimeters to frozen images, with text and arrows identifying the measured structure. Selected views and measurements can then appear together in a PDF report. Patient study records retain the associated images and videos, keeping the numerical assessment connected to the captured anatomy.

Depth and brightness adjustment

Imaging depth is adjustable up to 30 cm, allowing the displayed field to match the region under examination. Overall gain changes image brightness, and time gain compensation adjusts brightness through different depths. Frequency selection provides another control within the 1.3–3.7 MHz band. These settings let the operator balance visible anatomy and its presentation as probe position or the acoustic window changes.

Harmonic imaging and image presentation

Tissue harmonic imaging uses echoes at a multiple of the transmitted frequency to form the image. B-mode supports 256 grey shades, with dynamic range and grey-map settings determining how echo intensity appears on screen. Persistence averages successive frames, and line density changes the number of scan lines. Energy-saving, normal, and high-performance settings provide three frame-rate modes, so you can adjust image presentation to the examination and operating conditions.

Wireless connection to a compatible display

A compatible smartphone, tablet or computer provides the display and app controls. The manufacturer specifies Android, iOS, and Windows support, and the current iOS app requires iOS 15 or later. The probe communicates over IEEE 802.11a/b/g/n Wi-Fi at 2.4 GHz or 5 GHz. USB also supports a cable data connection, giving the scanner an additional connection method within its display-based workflow.

Handheld controls and status indication

At 194 × 74 × 40 mm and 350 g including its battery, the probe places power and freeze controls on the housing. A freeze press holds the image or returns it to live scanning. Coloured indicators show power, Wi-Fi connection, charging, and low-battery status. Fan-assisted cooling dissipates heat during operation, while the app presents the imaging controls on the paired display.

Cine review and clip selection

Freezing an examination retains the latest 200 frames for review. The operator can move through this sequence to select a view, add measurements or save an image. A selected portion can also become a video clip, with an adjustable duration and a three-second default. This keeps recent movement available after image acquisition has paused, supporting review of the sequence around a chosen cardiac frame.

Images, video and PDF reports

Saved images and videos belong to individual patient study records in the app. Still-image export supports JPG, PNG and BMP, and video export uses MP4. A PDF report can combine patient information, selected images, measurements, annotations, a signature and the date. These output formats preserve different parts of the examination: individual views, motion sequences and the written record associated with the captured study.

Optional DICOM exchange

The optional DICOM 3.0 interface adds medical-image export and transfer to a DICOM server. Worklist retrieval brings examination information into the app, while saved DICOM images carry image-related information alongside the scan. This supports a structured route between the handheld examination and a compatible imaging system. DICOM remains a distinct software option within the LU710PA configuration, alongside the app's standard image, video and PDF exports.

Battery capacity and operating cycle

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

USB charging and an optional dock

USB charging accepts 5 V DC at up to 3 A, with a maximum charging power of 15 W. An optional compatible charging dock provides a place for the probe between examinations. Its input accepts 100–240 V AC at 50/60 Hz, and its output is 5 V DC at 2 A. The charging indicator lights blue and turns off when the battery is fully charged.

Coupling and intact-skin reprocessing

Compatible ultrasound gel couples sound between the transducer and the patient's skin. For intact-skin examinations, reprocessing includes cleaning, followed by low-level disinfection with 70% isopropyl alcohol. Wiping removes coupling gel and visible material before disinfection. The LU710PA's patient-contact component is classified as a Type BF applied part, describing its electrical protection during patient contact. Reprocessing takes place between patient examinations.

Operating conditions in clinical rooms

The probe operates at 0–35°C, 15–95% non-condensing humidity and 700–1060 hPa. Its storage temperature range is −20 to 50°C. These limits describe the scanner, while compatible display devices have their own operating requirements. The LU710PA is intended for professional healthcare environments, where trained ultrasound users perform examinations and manage image capture, measurements, and patient study records.

The LU710PA suits clinicians whose handheld ultrasound workload centres on cardiac assessment and includes abdominal or acute bedside examinations. Its phased array provides a defined sector for examining anatomy and motion, with depth set around the target structures. A compatible viewing device and the app complete the scanning setup. Departments planning to use it can account for the rechargeable battery, the stated operating cycle, and surface reprocessing after intact-skin contact. Optional flow modes extend the information available within that workflow. The probe's cardiac role is supported by its dedicated preset and cardiology measurement tools. Maximum imaging depth is 30 cm.
