Leltek LU700C

Abdominal examinations use the LU700C's curved array to display a 60° field at depths reaching 18 cm. Renal, Spleen, and Bladder Meas. presets store common examination settings in the companion app. The same interface holds the live image, measurement tools and patient study, bringing acquisition and recording into one software workspace. Its integrated battery and imaging electronics support the handheld arrangement during these examinations.

In obstetric and gynaecological services, GYN, OB Early and OB Mid Late presets organise the examination around the selected application. Automatic obstetric measurement is included, and image annotations can identify the structures captured. A clinician can review the cine sequence, select a frame and retain measurements with the study. The report then combines those findings with chosen images and the examination's patient information.

Hospital emergency departments can use the LU700C for FAST and extended FAST examinations. The FAST preset provides a starting configuration in the app, with B mode showing anatomy and M mode displaying motion over time. It also supports peripheral vessel, nerve, and musculoskeletal imaging. For interventional work, real-time imaging supports trained professionals using freehand needle or catheter guidance.

The system suits departments that use a compatible display alongside the examination couch and keep their imaging records in the companion software. Wireless transmission connects the probe to the display, while study controls manage saved images, clips, and reports. Coupling gel supports acoustic contact during scanning. Clean and perform low-level disinfection after intact-skin use, and rechargeable power supports a 30-minute use and 10-minute rest cycle.

Acquisition hardware within the handpiece

The probe contains the transducer array, beamforming electronics, battery, and wireless components needed to acquire and transmit ultrasound images. The app presents that image and its examination controls on a compatible device. Power and freeze buttons remain on the probe for use during acquisition.

Presets organised around abdominal examinations

Renal, Spleen and Bladder Meas. presets sit alongside Abdomen and Abdomen Difficult settings. Each provides an examination-specific starting point within the app, while gain, depth and other controls remain adjustable. A clinician can retain preferred settings as a custom preset for later use. The same interface therefore carries both named examination choices and the adjustments used to shape a particular view.

Anatomy and movement in the standard configuration

B mode and M mode are part of the standard imaging configuration. An anatomical view establishes the position of a selected line, and M mode then shows movement along that line over time. Optional colour and power Doppler add flow information, while optional pulsed wave Doppler presents a velocity trace from a selected sample position. The companion app controls the imaging functions.

Obstetric measurement within the examination

The automatic obstetric measurement tool operates alongside the early and mid-to-late obstetric presets. It brings calculated measurements into the same software environment as the scan, where the professional can review the displayed anatomy and resulting values. Saved images and PDF reports can retain measurements as part of the examination record. This connects image acquisition, measurement, and documentation as parts of the product's obstetric workflow.

Frames available after acquisition pauses

Freezing the image opens access to the latest 200 frames in the cine buffer. The clinician can move through that sequence to select a frame for measurement or storage. This is useful when an anatomical boundary is most clearly represented at a particular point in the sequence. Image review remains within the app, with annotations and measurement tools available alongside the captured view.

Study records with several output formats

Retain still images, video clips, and reports with patient study information. JPG, PNG and BMP support image output, MP4 preserves clips, and PDF brings selected images and examination details into a report. Optional DICOM 3.0 adds server upload and worklist functions.

Routine care for skin-contact examinations

For examinations involving intact skin, the probe's reuse process consists of cleaning followed by low-level disinfection. Leltek specifies 70% isopropyl alcohol for the device, with visible gel and soil removed during cleaning. Probe care takes place before and immediately after use. The repeat-use arrangement includes a rechargeable handpiece, compatible coupling gel and a surface-care process that accompanies each examination.

Battery power carried with the probe

The integrated 6000 mAh lithium-ion battery supplies the scanner during wireless examinations. Approximate per-charge operation is 4.5 hours in B or M mode, 3.5 hours with colour or power Doppler, and 2.5 hours with pulsed wave Doppler. The operating cycle allows up to 30 minutes of use before a 10-minute rest.

Choice of compatible examination display

Leltek specifies compatibility with Android, iOS, and Windows devices, including compatible smartphones, tablets, and computers. The separate display carries the controls, patient information and saved images while the handpiece remains at the scanning site. This gives the examination setup support for multiple screen formats. The current iOS app requires iOS 15 or later and supports USB data communication.

Convex array with an 18 cm depth range

128 elements transmit and receive ultrasound across a curved scanning face. The LU700C operates at 2.0–5.0 MHz and displays a 60° field, with imaging depth extending to 18 cm. A 60 mm curvature radius defines the contact geometry. Adjustable depth sets how much anatomy is shown beneath the scanning surface during abdominal or obstetric assessment.

Two standard imaging displays

An anatomical view appears in B mode as a two-dimensional greyscale image. Switching to M mode plots motion through time along a selected line in the scan. Both displays are standard LU700C functions. The line position remains tied to the anatomical view, allowing the operator to relate the changing trace to the tissue crossed by the line.

Examination presets and saved settings

Abdomen, Abdomen Difficult, Renal, GYN, OB Mid Late, OB Early, Spleen, Bladder Meas. and FAST provide named starting configurations. A selected preset brings its imaging parameters to the examination screen, where you can still adjust individual settings. The app can store a custom combination for later selection. This keeps the starting configuration and subsequent image adjustments within the same scan controls.

Obstetric tools and image callipers

The LU700C app includes automatic obstetric measurement. On a frozen image, point-to-point distance and ellipse tools also measure length, area and perimeter. Measurements appear against the retained anatomy and can accompany selected images in the report. Leltek specifies full-screen B-mode maximum measurement errors of 1.81% vertically, 1.67% horizontally and 1.81% for circular area.

Gain adjustment across the displayed depth

You can adjust brightness for the whole image with gain, or for specific depths with time gain compensation. The latter adjusts the amplification applied to echoes returning from different tissue depths. Frequency selection works within the 2.0–5.0 MHz band. These controls sit beside the live image, so the displayed anatomy and its current settings remain part of one examination interface.

Harmonic imaging and greyscale processing

Tissue harmonic imaging forms a view using harmonic components in the returning ultrasound signal. The B-mode display represents echoes through 256 shades of grey, with dynamic range and grey-map settings controlling their tonal appearance. Persistence averages successive frames, while line density adjusts the number of scan lines. Image enhancement and three frame-rate settings provide further control over the displayed sequence.

Optional colour and power flow displays

Optional colour Doppler can add flow information to the anatomical image. Its adjustable region of interest defines where the flow overlay appears. Optional power Doppler represents the strength of the received Doppler signal within the selected region. Both options retain the surrounding tissue view, placing flow information in its anatomical setting during peripheral-vessel or other indicated examinations.

Optional pulsed wave velocity trace

With the pulsed wave Doppler option enabled, a selected sampling position supplies a flow-velocity waveform. Gate size, angle correction, baseline and gain are adjustable. The waveform records velocity changes over time while the anatomical image identifies the sampled location. For the LU700C, Leltek specifies a maximum velocity-measurement error of 3.00% across the full-screen range in this mode.

Direct Wi-Fi to the viewing app

Inside the probe, the battery, beamformer and Wi-Fi electronics support image acquisition and communication with the display. The direct wireless link uses 2.4 GHz or 5 GHz through IEEE 802.11a/b/g/n. Leltek specifies compatibility with Android and iOS mobile devices and Windows computers running its ultrasound app. The current iOS version requires iOS 15 or later, with examination controls presented on the connected device.

Handheld controls and visible operating states

The 388 g unit includes its battery within a 187 × 74 × 40 mm housing. Two physical buttons handle power and image freezing. Pressing freeze holds the scan or restarts live acquisition, while the app carries the remaining imaging controls. Indicator colours distinguish connection, power, charging and low-battery states, and an internal fan moves heat through the housing outlet.

Cine selection from 200 retained frames

Once scanning is frozen, the latest 200 frames are available as a review sequence. Moving through these frames lets you select a view for measurement, annotation, or saving. A section of the sequence can also be recorded as video. The clip length is adjustable, beginning with a three-second default, so the saved recording contains the selected interval.

Study records with image and report exports

Patient details organise the saved views and video clips into examination records. Text, arrows and body marks add context to individual images. Export stills in JPG, PNG, or BMP format, and videos in MP4. The PDF report combines selected views with patient information, measurements, annotations, a signature and the examination date, keeping the recorded findings associated with the study.

Optional DICOM archive connection

DICOM 3.0 adds an optional format for transferring medical images and their associated study information. The LU700C app can export DICOM images, upload them to a configured server and retrieve examination details through a worklist. These functions connect the saved scan with a compatible imaging archive. Server settings and worklist controls are held within the app used for the examination.

Rechargeable battery and defined working periods

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

USB charging with an optional dock

USB provides a data connection and a 5 V DC charging supply of up to 3 A. Between examinations, the integrated battery can also be replenished through a manufacturer-compatible optional dock. It accepts 100–240 V AC at 50/60 Hz and outputs 5 V DC at 2 A. The probe's blue charging indicator goes out when charging is complete.

Coupling gel and surface care

During intact-skin imaging, compatible ultrasound gel carries sound across the transducer face-to-skin interface. Reprocessing combines cleaning with subsequent low-level disinfection using 70% isopropyl alcohol. This surface routine supports repeated use of the probe between examinations. Leltek rates the LU700C IPX1, and the patient-contact transducer is a Type BF applied part for electrical protection.

The LU700C suits departments that want abdominal and obstetric ultrasound centred on a handheld probe and a compatible app display. Its main value is how acquisition, examination presets, measurements, and study records work together in that setup. Renal and bladder views, pregnancy examinations and FAST assessment fit its convex imaging format and named presets.

Routine operation includes battery charging, compatible coupling gel and cleaning followed by low-level disinfection for intact-skin use. Mode-dependent runtime and the 30-minute use cycle shape how it serves successive examinations. Optional Doppler and DICOM functions extend flow assessment and study transfer. Its scanning head provides a 60° field of view.
