The Visionstar SJD-C14 is a battery-powered dental X-ray generator weighing 2.14 kg, measuring 180 × 140 × 140 mm. It operates at 60 kV and 1.2 mA from a 30 kHz generator rated at 60 VA, with exposure timing from 0.2 to 3.2 seconds. The battery is a DC 16.8 V, 2300 mAh pack.

The interface is what distinguishes this unit. A display carries adult and child mode selection alongside tooth-position selection, and the manufacturer prints an exposure time reference table covering eight tooth positions for both patient groups, with separate columns for film and for sensor. That structure puts a starting exposure value in front of the operator for the specific view being taken, which is a sensible way to organise a control face and a genuine aid to consistency across a team.

It needs one qualification. Manufacturer reference values are a starting point, not your protocol. Under IR(ME)R 2017 exposure factors are optimised for your equipment, your receptors and your patients, and the values that govern your practice are the local diagnostic reference levels agreed with your Medical Physics Expert. Use the printed table to inform that conversation rather than to replace it, and confirm at order whether the stored values behind each selection can be edited.

Focal spot to skin distance is published at 100 mm. UK dental guidance sets a minimum focus-to-skin distance that steps up above 60 kV, commonly expressed as 100 mm at 60 kV and below and 200 mm above it, so this figure is consistent with 60 kV operation and sits at the minimum for that band. The tube's own nominal operating voltage is stated as 70 kV, so confirm with the manufacturer that unit output is fixed at 60 kV and cannot be configured higher, since the longer distance requirement would then apply.

The tube uses a tungsten target at a 19° target surface angle, with a stated anode heat capacity of 70 kJ. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation and service cover for the SJD-C14 across the United Kingdom.

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-C14 is configured for that daily volume. It supports bitewing caries detection, periapical assessment of pathology, endodontic working-length and obturation verification, alveolar bone-level review, and root morphology assessment ahead of extraction.

Paediatric practice is served directly by the interface. Separating patient group from tooth position, and presenting a starting exposure value for each combination, makes reduced factors for smaller patients a deliberate selection. Community dental services carry much of that caseload, and paediatric exposure factors belong in the protocol set agreed with a Medical Physics Expert.

The separate film and sensor columns in the manufacturer's reference table suit practices running mixed receptor types across surgeries, or working through a phased change, since each is addressed distinctly.

Community and special care teams need equipment one clinician can carry. At 2.14 kg net, the unit travels, though the published operating range of 10 to 40 °C is worth noting for domiciliary work in unheated buildings, and off-site radiation protection arrangements need to be agreed with the RPA in advance.

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.

Exposure organised around the view

Patient group and tooth position are selected directly, with an associated exposure value presented for each combination. That is how protocols are written, so the interface matches the way the work is actually structured.

Consistency across a shared team

Where several operators use one unit, selection by view means everyone reaches the same setting for the same projection, which makes an image quality audit interpretable and points findings at the protocol rather than at individual habit.

Paediatric factors as a deliberate selection

Separating child from adult at the control face makes reduced exposure for smaller patients an explicit choice rather than a remembered adjustment, with the values themselves agreed with your Medical Physics Expert.

Film and sensor addressed separately.

The manufacturer's reference table gives distinct columns for film and for sensor, which suits practices running mixed receptor types or working through a phased change.

Focal spot to skin distance published.

A stated 100 mm figure lets your Radiation Protection Adviser assess the geometry before commissioning rather than measuring it afterwards.

Heat capacity stated for multi-view work.

A 70 kJ anode capacity gives practices running long sessions something definite to plan against, with duty cycle the follow-up question for the manufacturer.

Full tube parameters disclosed

Target material, target surface angle, filament parameters and heat capacity are all published, giving your RPA and service engineer an unusually complete picture of the tube at the specification stage.

Data sheet questions surfaced before order.

Two focal spot figures, filtration stated for the tube rather than the beam path, and a 220 V charger input all need clarifying. Medigear.uk can arrange for each to be put to the manufacturer with your quotation.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

They organise exposure selection around the view. The operator selects the patient group and tooth position, and the unit presents the associated exposure time, which the manufacturer sets out in a printed reference table covering eight positions for both groups with separate film and sensor columns. On a shared unit that supports consistency, since every operator reaches the same setting for the same view. Confirm at order whether the stored values can be edited.

As a starting point for a conversation with your Medical Physics Expert, not as your protocol. Manufacturer reference values cannot account for your receptor speed, collimation, total filtration or patient mix, and under IR(ME)R 2017 optimisation is done for your installation. Agree your values with your MPE, record them as local diagnostic reference levels, and audit image quality against them.

This needs resolving before order. The main table states a tube focus of 0.3 mm × 0.3 mm, while the tube parameter block gives a nominal focal spot value of 0.8. Those are materially different figures, and focal spot size governs geometric unsharpness at the receptor — it affects what fine detail the unit resolves and forms part of what your RPA and Medical Physics Expert assess. Ask which figure describes the unit as supplied, in writing. Medigear.uk can arrange for that clarification with your quotation.

Not as a total. The tube parameter block lists filtration of 1 mm aluminium, which reads as the tube's own contribution rather than the filtration of the complete beam path. Total filtration is the figure a Radiation Protection Adviser works from, and a minimum of 1.5 mm aluminium equivalent is commonly cited for intraoral sets operating up to 70 kV. Request the total filtration figure and the half-value layer data, and have your RPA review both before the unit is put into service.

For 60 kV operation, it matches the minimum commonly cited in UK guidance for sets at 60 kV and below. Two things follow. First, it sits at that minimum rather than above it, so there is no margin, and your RPA should be told the figure explicitly. Second, because the tube is rated at a nominal 70 kV, confirm that the unit output is fixed at 60 kV — if it can be configured higher, the longer minimum distance applies, and the supplied applicator would need to deliver it.

Ask before ordering. The data sheet gives a charger input of 220 V at 50 Hz rather than a wide 100–240 V range. UK mains is nominally 230 V with a tolerance band that runs higher still, so confirm with the manufacturer that the supplied charger is rated for UK supply voltage across its full range, and ask whether a wide-input adapter is available. This is a straightforward question that is much easier to answer before delivery.

It describes how much energy the anode can absorb, which governs how many exposures can be taken in close succession before a cooling interval is needed. A stated figure lets a practice running long multi-view sessions plan against something definite. The anode also cools continuously between exposures, so the working limit depends on duty cycle; ask the manufacturer for the cooling curve if your sessions routinely run long.

The Ionising Radiations Regulations 2017 require employers carrying out dental X-ray work to register with the Health and Safety Executive, appoint a Radiation Protection Adviser, nominate a Radiation Protection Supervisor and complete a radiation risk assessment. The Ionising Radiation (Medical Exposure) Regulations 2017 add the appointment of a Medical Physics Expert, justification and optimisation of each exposure, and documented training for referrers, practitioners and operators. A critical examination is required when the equipment is put into service.

Dental X-ray equipment is subject to routine quality assurance and periodic radiological testing under IRR17, alongside annual electro-mechanical inspection, with a critical examination required at installation. UK service providers commonly apply an annual radiological testing interval to hand-carried units. Warranty terms are set and issued by the seller or manufacturer, typically 12–24 months for this equipment class — confirm the term, the parts covered and the battery position at quotation.
