Leltek LK128L

The LK128L serves clinicians who examine tissue close to the skin and want a handheld scanner. Vascular and general outpatient clinics use the carotid and peripheral vessel presets, where colour and power Doppler show flow and the automatic IMT measure records the carotid wall thickness from a frozen sagittal view. The probe's 12.6 cm depth covers the neck and limb structures those exams reach, and the paired screen keeps the operator facing the person being scanned.

Thyroid and breast services work with the Thyroid and Breast presets. The 4.2 to 12.5 MHz range resolves fine detail in small organs, and the clinical measurement tools record the dimensions of what the operator finds. Musculoskeletal and physiotherapy rooms use the MSK preset for muscle, tendon and joint surfaces, and the optional subcutaneous fat measurement adds an automatic thickness reading for skin, fat and muscle layers.

Nerve imaging uses the Nerve preset, and the needle enhancement function supports needle work at the shallow depths where nerves and superficial targets lie. Because the probe weighs 223 g and has its own battery, it moves between rooms with the operator and needs only a paired screen, so a single probe can serve an entire outpatient floor.

Qualified physicians, sonographers and trained clinical staff operate the probe. The paired Android, iOS or Windows screen can be a phone, tablet or laptop that the clinic already uses, and optional DICOM 3.0 lets sites that archive studies send images to their imaging record. The IP68 body suits are suitable for rooms where gel, wipes and cleaning are routine.

One probe across the superficial exam list

Breast, Carotid, MSK, Nerve, Peripheral Vessels, Superficial and Thyroid presets sit on the same 4.2–12.5 MHz linear array. A clinic that scans several of these areas needs one probe, and training follows one routine.

Automatic IMT measurement in the standard configuration

Carotid preset, sagittal freeze and the IMT measure produce an automatic wall-thickness reading. The function needs no option, so every LK128L carries it from the first scan.

Optional subcutaneous fat measurement

For musculoskeletal and superficial work, the optional fat measure colours the fat layer yellow and the muscle layer red and automatically measures each thickness. It adds to the same probe when a clinic needs it.

Presets that start the exam

The operator selects the target area and scanning begins from matched settings. The preset list shortens the first minute of each study and keeps image quality consistent between operators.

Needle enhancement for needle work

The needle enhancement function is part of the standard configuration. It supports needle placement under ultrasound at shallow depths, where the 4.2 to 12.5 MHz range resolves the target.

A wireless link to the screen already in hand

Dual-band Wi-Fi sends the image to a phone, tablet, or laptop on Android, iOS, or Windows. Staff keep the probe in one hand, and a familiar screen in the other, and the exam moves with the operator.

Up to two hours of scanning per charge

The built-in lithium-ion battery supports up to 2 hours of working time. A full outpatient list fits inside one charge, and USB Type C charging at up to 15 W restores the probe between sessions.

An IP68 body for gel, wipes and clinic rooms

The manufacturer rates the probe IP68 for dust and water. The rating is for rooms where gel and frequent cleaning are routine, and the 223 g body stays comfortable through long lists.

FDA 510(k) clearance and declared safety standards

The LK128L holds FDA 510(k) clearance under K241161 as a Class II ultrasonic imaging system. The manufacturer declares conformity to ANSI/AAMI ES60601-1, IEC 60601-1-2, IEC 60601-2-37, IEC 62133-2 and IEC 62304, covering electrical safety, electromagnetic compatibility, ultrasound equipment, lithium battery safety and software life cycle.

128-element linear array

The array carries 128 supported elements at a pitch of 0.3 mm. The element count and pitch define the beam that forms the linear image across the probe face width.

4.2–12.5 MHz operating range

Frequencies from 4.2 to 12.5 MHz let the beam resolve fine detail in shallow tissue. The chosen preset applies the working frequency, so the examination decides the setting.

12.6 cm maximum depth

Imaging extends to 12.6 cm below the probe face. That depth covers the neck, breast and limb structures that superficial exams reach.

2 cm elevation focus

The elevation focus sits at 2 cm, which concentrates slice thickness in the shallow zone where thyroid, nerve and vessel targets are most often imaged.

Application presets

Breast, Carotid, MSK, Nerve, Peripheral Vessels, Superficial and Thyroid presets load settings for the chosen exam. Each one is a starting point that the operator adjusts as the study proceeds.

Automatic IMT measurement

Under the carotid preset, a frozen sagittal view and the IMT measure automatically calculate intima-media thickness. The function is part of the standard configuration.

Optional automatic subcutaneous fat measurement

Under the MSK preset, a frozen sagittal view of skin and muscle and the fat measure show the subcutaneous fat layer in yellow and the muscle layer in red. The thickness of each is measured automatically. It is available as an option.

Needle enhancement function

Needle enhancement is built into the standard configuration for ultrasound needle work. It works within the same app as the other imaging tools.

Clinical measurement tools

The app's measurement tools record distances and other values on a frozen image. They are part of the standard configuration alongside the automatic measurements.

B-mode and M-mode imaging

B-mode gives the two-dimensional grey-scale image used in every preset. M-mode traces movement along one scan line against time, which suits timing of moving structures.

Colour Doppler and power Doppler

Both Doppler modes are part of the standard configuration. Colour Doppler marks flow direction on the image, while power Doppler shows where flow exists with high sensitivity.

Optional pulsed-wave Doppler

Pulsed-wave Doppler is available as an option. The mode measures flow velocity at a chosen sample point and displays it as a spectrum on the same probe.

Optional DICOM 3.0

Sites that archive ultrasound studies can add DICOM 3.0 as an option. It brings standard-format image export to the existing workflow.

Dual-band Wi-Fi link

The probe joins the paired device over 802.11 a/b/g/n Wi-Fi on 2.4 and 5 GHz. Two bands give you a choice of channels when wireless traffic is heavy.

Lithium-ion battery and USB Type-C charging

The rechargeable battery supports up to 2 hours of working time. A USB Type-C port charges at up to 15 W through a connector most clinics already have.

IP68 body at 223 g

The sealed body is rated IP68 and weighs 223 g, with outer dimensions of 167 × 57 × 31 mm. The size suits one-handed use through long examination lists.

Real-time app and firmware upgrades

App and probe firmware upgrades arrive in real time. New features and refinements reach every LK128L in a clinic without anyone handling the hardware.

The LK128L suits clinics that scan superficial tissue across several areas and want one wireless probe to cover them. Its strongest case is breadth: seven application presets, automatic IMT measurement in the carotid routine, and an optional fat measure all run on a single 4.2–12.5 MHz array. With up to 2 hours per charge, an IP68 body, and support for Android, iOS, and Windows, it's practical in outpatient, vascular, thyroid, breast, and musculoskeletal rooms, while real-time upgrades keep software upkeep light. The probe weighs 223 g, measures 167 × 57 × 31 mm and holds FDA 510(k) clearance under K241161.
