The Visionstar SJD-C12 is a battery-powered dental X-ray generator operating at 60 kV and 2 mA from a 30 kHz generator rated at 60 VA, with exposure timing from 0.1 to 2.0 seconds. The tube focus is 0.4 mm × 0.4 mm, the published distance from skin to cone is 130 mm, and power comes from a DC 14.8 V, 2200 mAh lithium pack charged from an AC 100–240 V ±10% supply.

Two of those figures do most of the work in determining what the images look like. Focal spot size governs the penumbra at the edge of every structure recorded — a finite source casts a soft edge rather than a hard one, and the softer that edge, the harder it becomes to resolve a fine fracture line, an early carious lesion or the margin of a restoration. A 0.4 mm square source is the specification behind the detail this unit can deliver.

Cone distance governs magnification. The tooth sits between the focal spot and the receptor, so every intraoral image is enlarged to some degree, with the enlargement depending on how far the source sits from the object relative to the receptor. A 130 mm skin-to-cone figure exceeds the 100 mm minimum commonly cited in UK guidance for equipment operating at 60 kV and below, which is a useful position rather than a bare one.

Neither figure works without technique. Both magnification and penumbra shrink as the receptor comes closer to and more nearly parallel with the tooth, which is what a paralleling holder with a beam-aiming device achieves. The machine sets the ceiling; the holder and the operator determine how much of it is realised.

Total filtration is not published on this data sheet, nor are unit dimensions or weight. Medigear.uk can arrange for those figures to be requested from the manufacturer, along with supply, delivery, commissioning, staff familiarisation and service cover for the SJD-C12 across the United Kingdom.

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-C12 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.

The geometry of the image shapes what each of those tasks can achieve. Bitewings depend on the beam meeting the line of the contact points squarely, because superimposed proximal surfaces conceal the interproximal areas the view exists to examine. Endodontic working-length films are measured, so the inevitable enlargement between tooth and receptor has to be accounted for through a reference of known length rather than read off the image. Periapical assessment of early bone change depends on edge definition, which is where focal spot size and receptor proximity come together.

Occlusal projections widen the range usefully. They are the standard means of locating an unerupted or ectopic canine in the palate, of demonstrating a salivary calculus in the submandibular duct, and of showing the extent of a cyst or a fracture across an arch. Because occlusal receptors are larger than periapical ones, confirm the X-ray field dimensions with the manufacturer before committing to that work — the field size is not published here.

Paediatric, special care and domiciliary work all benefit from a carried unit reaching the patient, though weight is not published on this data sheet and should be requested before single-person handling is assumed. Off-site radiation protection arrangements need to be agreed with the Radiation Protection Adviser 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.

A 0.4 mm source for edge definition

Focal spot size sets the ceiling on how sharply a boundary can be recorded, and a small square source is what allows a fine fracture line, an early lesion or a restoration margin to be resolved.

Cone distance with margin

A published 130 mm skin-to-cone figure exceeds the 100 mm minimum commonly cited for equipment operating at 60 kV and below, so the geometry starts from a position with room in it.

Magnification kept understood, not ignored.

Every intraoral image enlarges to some degree. Knowing that, and using a reference of known length when a measurement matters, is what keeps endodontic working-length films reliable.

Exposure control from 0.1 seconds

A twenty-fold timing span reaches the short values direct sensors call for and extends to two seconds for slower receptors, with the specific values set by your Medical Physics Expert.

Wide-input charging

The charger accepts AC 100–240 V ±10%, so the unit runs on UK mains directly and internationally with a plug adaptor.

Published environmental limits

Operation between 5 and 40 °C at under 75% relative humidity, which is worth checking against domiciliary settings in unheated buildings.

Icon-led control face

A colour panel with region and patient icons presents the selection directly, with plus and minus keys either side for adjusting the exposure value.

Missing figures identified before order

Total filtration, X-ray field size, weight and dimensions are all absent from the data sheet. Medigear.uk can arrange for each to be requested from the manufacturer with your quotation, so your Radiation Protection Adviser sees them before commissioning.

The Visionstar SJD-C12 gives UK dental teams a battery-powered X-ray generator built around a 0.4 mm × 0.4 mm tube focus and a published 130 mm skin-to-cone distance, running 60 kV / 2 mA from a 30 kHz generator with a 0.1–2.0 second exposure range and a DC 14.8 V 2200 mAh battery charged from a wide-input supply. It fits NHS and private general practice, bitewing and periapical work where image geometry decides the diagnosis, endodontics, occlusal projections subject to field size confirmation, paediatric and special care dentistry, and community services. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation, service cover and planned maintenance across the United Kingdom, and can arrange for the manufacturer's total filtration, half-value layer, X-ray field size, weight and dimension figures to accompany your quotation for your Radiation Protection Adviser's review.

FAQ

Frequently Asked Questions

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

Some magnification is unavoidable because the tooth lies between the focal spot and the receptor. The degree depends on the ratio between the focus-to-receptor distance and the focus-to-object distance, so it shrinks as the receptor is brought closer to the tooth. It matters most whenever a measurement is taken from the image — endodontic working length being the common example — which is why a file of known length or another reference object is used rather than measuring the radiograph directly. For qualitative assessment, it rarely changes the diagnosis.

The 0.4 mm focal spot sets the limit, and technique determines how close you get to it. A source of finite size casts a soft edge at every boundary, and that softness grows as the receptor moves away from the tooth and shrinks as it moves closer. Paralleling technique with a beam-aiming holder keeps the receptor close and correctly oriented, which is why the same machine produces noticeably different detail in different hands.

Overlap comes from horizontal angulation: if the beam is not directed perpendicular to the line of the contact points, adjacent surfaces superimpose and hide exactly the interproximal areas a bitewing is taken to examine. No exposure setting corrects it. The remedy is beam direction, supported by a holder with a bite block and aiming ring, and by taking a second view at an adjusted horizontal angle where the first is unreadable.

Occlusal projections are within the range of what an intraoral generator produces, and they earn their place for unerupted or ectopic teeth, palatal canine position, salivary calculi in the submandibular duct, and the extent of a cyst or fracture. One practical check applies: occlusal receptors are larger than periapical ones, and this data sheet does not publish the X-ray field size. Confirm the field dimensions with the manufacturer and satisfy yourself that they cover the receptor you intend to use before committing to occlusal work.

For 60 kV operation, it exceeds the 100 mm minimum commonly cited in UK guidance for sets at 60 kV and below, so it sits with margin rather than at the threshold. Give the figure to your Radiation Protection Adviser explicitly, since it feeds into the geometry they assess at critical examination, and confirm that unit output is fixed at 60 kV so the shorter minimum is the applicable one.

No. Neither inherent nor total filtration appears on the data sheet. Total filtration is the figure a Radiation Protection Adviser assesses beam quality 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 before order, and have your RPA review both ahead of commissioning.

Not published on this data sheet. Both matter for practical reasons — weight determines whether one clinician can carry the unit through a full list or a domiciliary round, and dimensions determine whether it stows in a lockable drawer, which is how most practices discharge the physical security duty IRR17 places on them. Request both figures at quotation.

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.
