Leltek LU710C

The LU710C supports abdominal ultrasound in hospitals, outpatient departments and diagnostic clinics. Its convex array provides a wide field for assessing abdominal structures, with imaging depth adjustable up to 30 cm. Renal, Spleen, and Bladder Meas. presets provide dedicated starting settings for these examinations. Battery operation brings the scanner to the examination position, while the connected screen carries image controls and measurements.

In obstetric and gynaecological departments, the probe supports transabdominal imaging with OB Early, OB Mid Late and GYN presets. The app's distance and area measurements record dimensions of the structures under assessment. The app can include image annotations and selected frames in the examination report. With the probe in hand and the display positioned nearby, the clinician can acquire views and document findings within the same examination session.

Acute care departments can use the FAST preset for focused ultrasound assessment, and the manufacturer also identifies lung imaging among the probe's applications. Leltek also identifies cardiac imaging and vascular access among its uses. Its freeze control retains an image during an examination, while the cine buffer supports review of the most recent image sequence. B-mode provides the underlying anatomical image. Optional Doppler functions add flow assessment when the examination uses those configured capabilities, with runtime specified for each mode.

For departments conducting repeated examinations, the scanner's battery and cleaning process form part of its daily use. The 6000 mAh battery supports about 4.5 hours in B-mode or M-mode, and a compatible charging dock is available in the equipment area. Between intact-skin examinations, the probe undergoes cleaning and low-level surface disinfection using 70% isopropyl alcohol. Its saved records retain images, measurements and annotations for subsequent clinical review.

Battery capacity for a run of examinations

The internal battery gives the scanner an operating window measured in hours, with duration linked to the selected imaging mode. A sequence of greyscale examinations and a pulsed-wave Doppler session each have their own stated runtimes. That distinction makes the battery specification useful to a department organising repeated scans. Charge status remains visible on the probe, so its power state stays part of the equipment's everyday handling.

A scanning setup carried to the examination

A 340 g probe and a compatible display device form the working imaging setup. The scanner can move between examination rooms and bedside locations within a healthcare facility, with the image displayed on the paired screen. Clinicians can position the display beside the patient while holding the probe at the examination site. This arrangement suits clinicians whose ultrasound work takes place at several examination positions during a clinical session.

A curved field for abdominal and pelvic work

The 60° sector presents a widening field as imaging depth increases, with a maximum depth of 30 cm. Renal, bladder, abdominal and obstetric presets place these uses within the scanner's operating scope. The practical value lies in combining those examination types with one curved array. Each preset provides an appropriate starting configuration, while the image controls allow the operator to adjust the view for the current examination.

Image capture from the hand holding the probe

The physical freeze control lets the clinician pause the image at the probe while keeping it in place on the skin. Frozen images then support annotations and measurements in the app. This creates distinct acquisition and review stages within the same examination. The stored frame can carry the measurement and its location together, preserving the visual context when the study is reviewed later.

Records organised around the examination

Images and video clips sit within the patient study record, alongside the information entered for that examination. PDF export brings selected images, measurements, annotations, signature and date into a report. The benefit is a connected record of the scan and the observations recorded during it. You can review saved material in the app, with still-image and video export available in supported formats.

Flow imaging as a defined configuration choice

Colour Doppler, power Doppler and pulsed-wave Doppler are available as options. Each presents flow information in its own form: a colour map, a display of Doppler signal strength, or a velocity trace over time. These options combine structural imaging and flow assessment in the handheld system. The selected modes also determine the battery runtime associated with the examination.

A display matched to the working setting

Leltek specifies compatible Android, iOS and Windows devices for the ultrasound app. This gives the probe a choice of supported phone, tablet and computer displays within its system design. A handheld display can accompany the probe at the bedside, while a compatible computer provides another viewing arrangement in an examination room. The scanner retains its battery and transducer, while the paired device displays the image.

Reusable hardware with a defined care routine

The scanner's recurring use centres on charging its internal battery, applying compatible ultrasound coupling gel and caring for the probe surface. For intact-skin scanning, its reprocessing method combines cleaning with low-level disinfection using 70% isopropyl alcohol. The series includes a charging dock with an accessory charging position between sessions.

Electrical safety with a stated scope

The LU710C holds FDA 510(k) clearance K243226 as a Class II device. Leltek declares that the LU710C is certified to IEC 60601-1, IEC 60601-1-2 and IEC 60601-2-37. These standards cover basic electrical safety, electromagnetic compatibility, and specific requirements for diagnostic ultrasound equipment. The declared certification applies to the ultrasound system and its stated configuration.

128-element convex array

A curved array of 128 elements forms the scanning surface, with a 2.0–5.0 MHz bandwidth and a nominal frequency of 3.2 MHz. Its 60 mm radius of curvature defines the transducer geometry. The elements transmit and receive ultrasound signals across that curved face, producing the sector-shaped image used for abdominal and obstetric examinations.

30 cm imaging depth

The LU710C provides an imaging depth of up to 30 cm within a 60° field of view. Depth adjustment changes how much tissue appears on the screen. Combined with the curved transducer, this range supports views through the abdomen, while the displayed depth scale provides a reference for the position of structures within the image.

B-mode and M-mode imaging

B mode displays a two-dimensional greyscale image of tissue, providing the anatomical view used to position the probe and inspect structures. M mode records movement along a selected scan line over time. Its time-based display adds motion to the examination, with the scan line overlaid on the anatomical image.

Optional colour and power Doppler

Colour Doppler and power Doppler are available as optional imaging modes. Colour Doppler places flow information within the anatomical image, while power Doppler displays the strength of the detected Doppler signal. Both support examining blood flow in the selected region. Their controls include the region of interest and mode-specific image settings.

Optional pulsed-wave Doppler

The optional pulsed-wave Doppler mode samples flow at a selected position and displays its velocity waveform over time. An adjustable sample gate defines the sampled area. Angle correction, baseline position, and gain control the trace, allowing you to assess the waveform alongside the anatomical location from which the signal was collected.

Nine application presets

The model's application presets cover Abdomen, Abdomen Difficult, Renal, GYN, OB Mid Late, OB Early, Spleen, Bladder Meas. and FAST. These selections provide starting settings for the named examination. The app also stores custom presets, so an operator can save a chosen combination of image parameters as a reusable starting point for the same scan type.

Wireless and micro-B connections

Wireless connection lets the display sit independently of the hand holding the transducer against the examination site. Image data travels over Wi-Fi, with IEEE 802.11 a/b/g/n communication supported on 2.4 and 5 GHz bands. The scanner also has a USB micro-B connection for cable data transfer and battery charging.

Android, iOS and Windows display

Leltek supports compatible Android, iOS and Windows devices through its LeSONO ultrasound app. A connected phone, tablet or computer displays the live image and provides the examination controls. The display device also holds the patient study and presents saved images for review, with report creation available within the same app.

6000 mAh rechargeable battery

An internal 6000 mAh lithium-ion battery powers the scanner during an examination. Approximate continuous operating times are 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 battery supports repeated charging, with a listed life of 300 discharge cycles and visible charging status on the probe.

Probe controls and status lights

The probe's freeze button pauses the live ultrasound image and resumes scanning. A separate power button controls the scanner itself. Status lights indicate power, wireless connection, battery charging and low charge. These controls keep image capture and device status at hand, alongside the examination functions available through the app.

Depth, gain and harmonic controls

Adjustable depth and gain control the displayed scan extent and image brightness. Time gain compensation adjusts brightness at different depths, while dynamic range and greyscale mapping shape tonal presentation. Tissue harmonic imaging provides an additional signal-processing mode. Persistence, line density and frame-rate settings give the operator further control over how the moving image appears during scanning.

Measurements on frozen images

Measurement tools operate on the frozen ultrasound image, letting you place dimensions directly against the visible anatomy. Distance measurement records the separation between selected points, and an ellipse tool calculates area and perimeter. Arrows, text notes and body marks add context to the saved view. The app also includes automatic obstetric measurement tools. Together, these tools preserve both the measured value and its location within the examination.

200-frame cine review

Freezing the scan makes the latest 200 frames available for cine review, allowing you to inspect the examination sequence frame by frame. Selected views can be saved as still images or video. Image export supports JPEG, PNG and BMP, while video export uses MP4. A clip can be created from the buffered frames, with a default duration of three seconds.

Patient records and PDF reports

Saved images and videos sit within the patient's study record in the app. The report function brings patient information, selected images, measurements, annotations, a signature and a date into a PDF. Review and export tools work with the stored examination, keeping the recorded views associated with the information that identifies the study and explains its findings.

Optional DICOM 3.0 connectivity

Optional DICOM 3.0 functionality connects the examination with compatible imaging systems through image export and transfer to a configured server. Worklist handling brings patient study details into the app. Server configuration and connection testing sit alongside those functions, providing the settings for a link between the scan and its imaging archive.

Surface cleaning and daily upkeep

The transducer uses ultrasound coupling gel to carry sound between its face and the skin. Its reprocessing method for intact-skin use combines surface cleaning with low-level disinfection using 70% isopropyl alcohol. This wipe-based routine is part of the probe's repeated use between examinations, along with battery charging and inspection of the scanning face and housing.

The LU710C suits clinicians whose regular work combines abdominal, renal, bladder and transabdominal obstetric imaging with movement between examination rooms. Its value comes from combining a curved array, battery power, and image recording in a compact scanning setup. For departments performing repeated examinations, the key operating choice is the imaging configuration: B and M modes provide structural and motion views, while optional Doppler modes add flow information, each with its own battery runtime. Daily use centres on charging, compatible coupling gel and surface care of the reusable probe. The paired app keeps images and measurements within the examination record, and optional DICOM connects that record to a compatible imaging system. The probe weighs 340 g with its battery.
