Visionstar SJD-C15D

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-C15D is configured for that daily volume. It supports bitewing caries detection, periapical assessment of apical pathology, endodontic working-length and obturation verification, periodontal bone-level review, and root morphology assessment ahead of extraction. Fixed 60 kV and 2 mA operation with variable exposure time maps cleanly onto region-by-region protocols agreed with a Medical Physics Expert and recorded in local diagnostic reference levels.

Implant dentistry draws on intraoral views for site review, healing assessment and abutment-level verification, and the manufacturer positions the unit for pre-treatment assessment of internal structure and root depth. UK practices work inside the justification framework of IR(ME)R 2017, selecting intraoral views where they answer the clinical question and requesting sectional imaging where bone volume, nerve position or three-dimensional anatomy is at issue.

Community dental services and special care dentistry teams operating under NHS commissioning need equipment that reaches the patient. People living with advanced dementia, profound learning disability, motor disorders or palliative care needs are frequently unable to transfer to a fixed dental chair, and assessment at the bedside or in a care home lounge is the practical route to diagnosis. Battery capacity of roughly five hundred exposures per charge suits that pattern of work, provided off-site radiation protection arrangements have been agreed with the practice's Radiation Protection Adviser in advance.

Orthodontic practices use periapicals for root resorption monitoring through active treatment. Paediatric dentistry benefits from short exposure values and from the ability to settle a child in position before the beam is aligned. Dental education, outreach programmes, prison dental services and expedition dentistry all depend on equipment that runs from a battery.

Guidance from the College of General Dentistry and UKHSA Dental X-ray Protection Services remains the reference point UK practices work to, alongside HSE enforcement of IRR17.

A display that stays legible where the work happens

High-contrast monochrome rendering holds up under an operating lamp and at oblique reading angles. Confirming the exposure value before the shot, without shading the panel or repositioning the head, is a small thing that pays back across every list.

One variable for the operator to set

Tube voltage and tube current are fixed at 60 kV and 2 mA by design. Exposure time is the only adjustable parameter. That shortens the training curve for newly qualified operators and returning staff, and narrows the scope for setting error under time pressure.

Consistent output from high-frequency drive

A 200 kHz DC inverter holds tube voltage close to constant potential across the exposure. Steady output produces steady receptor density, which cuts retakes caused by under- or over-exposure and keeps cumulative patient dose lower through a course of treatment.

A full working day between charges

Approximately five hundred exposures from a single charge covers a general practice list comfortably and supports a complete round of community visits. A rated life of around one thousand charge cycles makes the pack a long-interval consumable for budget planning.

Detail that supports root-level decisions

The 0.4 × 0.4 mm focal spot limits geometric unsharpness, which is what makes lamina dura, trabecular pattern and apical anatomy readable. Those structures are exactly what root depth assessment, endodontic length verification, and implant site review turn on.

Ready for a digital record

Designed to feed an intra-oral digital X-ray imaging system, the unit drops into an existing sensor and image-management workflow, with an exposure range reaching the short values direct sensors need.

Sealed, consolidated construction

Control electronics sit on a central PC board, and the tube assembly uses insulated vacuum construction inside sealed protective moulding. Fewer discrete assemblies means fewer service points and a shell that withstands daily surgery handling.

UK supply, commissioning and service through one route

Medigear.uk can arrange listing, supply, delivery, installation, commissioning, staff familiarisation, service cover, planned maintenance and quotations for the SJD-C15D across the United Kingdom, with site survey support where a practice wants the radiation protection conversation scoped before order.

Monochromatic display panel

A high-contrast monochrome screen presents the active exposure value and machine state, maintaining legibility under strong surgical lighting and at oblique viewing angles.

Shell-mounted manual buttons

Control buttons set into the housing surface give positive tactile feedback under gloves and present a wipeable control face for routine decontamination.

90 W rated power

The generator is rated at 90 W, sizing the supply to sustain fixed 60 kV / 2 mA output across the full exposure time range.

Fixed 60 kV tube voltage

Operation at a fixed 60 kV sits within the established kilovoltage range for intraoral dental radiography and supports adequate contrast for caries and periapical assessment.

Fixed 2 mA tube current

Holding tube current constant means the exposure product is governed entirely by time, which simplifies protocol design, audit and operator training.

200 kHz DC high-frequency inverter

High-frequency drive produces a near-constant potential waveform, delivering steadier output per exposure and a beam carrying proportionally fewer low-energy photons.

0.4 × 0.4 mm focal spot

A small square focal spot limits geometric unsharpness at the receptor, underpinning fine detail visibility on periapical views.

0.2–3.2 second exposure range

A sixteen-fold span of exposure time covers direct sensors at the short end and phosphor plate or film technique at the long end, across all intraoral regions.

Central PC board architecture

Control electronics are consolidated onto a single board, reducing internal interconnection and the number of discrete service points.

Insulated vacuum tube assembly with sealed moulding

The tube assembly uses insulated vacuum construction inside a sealed protective moulding, protecting the high-voltage section against moisture ingress and handling shock.

14.8 V 6600 mAh lithium battery with DC 16.8 V rail

A high-capacity lithium pack feeds a DC 16.8 V internal rail and holds voltage well through the discharge curve, supporting consistent output across a session.

Universal AC 100–240 V ±10% charging

The charger accepts a wide input range at 50/60 Hz, so the unit runs on UK mains directly and internationally with a plug adaptor.

Moulded hand strap

An integrated strap across the housing supports single-hand carrying and steadier beam alignment while the exposure is taken.

Specified environment: 5–40 °C, below 75% RH

Published ambient temperature and humidity limits define where the unit may be operated and stored, which matters for outreach and vehicle-based work.

The Visionstar SJD-C15D gives UK dental teams a battery-powered DC high-frequency X-ray generator with a high-contrast monochromatic display, shell-mounted manual controls, 90 W rated power, fixed 60 kV / 2 mA output, a 0.4 mm focal spot, 0.2–3.2 second exposure range and a 14.8 V 6600 mAh lithium pack rated for around five hundred exposures per charge. It fits general dental practice, implant and referral clinics, orthodontics, paediatric and special care dentistry, community dental services and outreach programmes.
