The Visionstar SJD-131 is a battery-powered dental X-ray generator for intraoral radiography at the point of care. The generator runs at 30 kHz, with tube voltage selectable at 60 or 70 kV, tube current selectable across 1.5, 2.0, 2.5 and 3.0 mA, and exposure timing from 0.1 to 2 seconds. Tube focus is specified at order as 0.4 mm or 0.8 mm.

The control face carries a 2.4 inch dot matrix display. A dot matrix panel forms characters from an illuminated cell grid, which allows generous character height across a screen of that size and holds legibility at working distance and at the oblique angles an operator reads from while the head is held in position. Where the operator is already managing patient positioning, receptor placement and beam alignment, a readout that can be confirmed at a glance removes one thing from the sequence.

Exposure timing spans 0.1 to 2 seconds — a twenty-fold range. That envelope, combined with two kilovoltage settings and four milliamp steps, gives a Medical Physics Expert genuine scope when writing protocols that vary properly by region, patient build and receptor speed, as the optimisation duty under IR(ME)R 2017 expects. Agree the values with your MPE and record them as local diagnostic reference levels.

Published distance from skin to cone is 130 mm. Raise that figure with your Radiation Protection Adviser during specification, since UK dental guidance sets minimum focus-to-skin distances that differ for equipment operating above 60 kV, and this unit offers a 70 kV setting.

Power comes from a DC 14.8 V 1600 mAh lithium pack, charged from AC 100–240 V with a DC 16.8 V output, rated at 100–300 VA. The unit measures 110 × 140 × 165 mm and weighs 1.7 kg, with a moulded hand strap for single-hand carrying. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation and service cover for the SJD-131 across the United Kingdom.

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-131 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.

Dental trauma is a distinctive fit. Avulsion, intrusion, luxation and root fracture present urgently, often out of hours, frequently in children, and commonly in a patient who is distressed and unwilling to move. Assessment usually needs more than one view of the same tooth at differing angles before a fracture line can be resolved or excluded. Equipment carried to a patient already settled in position, with a readout confirmed at a glance while the operator's hands are occupied, suits that work. Each view still needs individual justification under IR(ME)R 2017.

Restorative dentistry uses bitewing and periapical views for margin assessment, overhang detection, secondary caries at restoration margins and the relationship between a restoration and the pulp chamber. The higher kilovoltage setting produces the longer greyscale that dense restorative material and surrounding tooth structure both require in one image.

Endodontic practice makes heavy use of periapical views, with a single root canal treatment often needing a diagnostic film, a working-length film, a master cone check and a post-obturation view. Paediatric dentistry benefits from the lower milliamp steps and the 0.1 second timing floor.

Community dental services and special care teams need equipment one clinician can carry. At 1.7 kg, the unit travels easily, though the modest published battery capacity makes spare pack availability worth settling before a domiciliary round or an out-of-hours rota, with off-site radiation protection arrangements 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.

A readout confirmed without leaning in

Dot matrix character formation across a 2.4-inch panel gives figures readable at working distance and at oblique angles. During positioning, when one hand is on the tube head and attention is on the receptor, that removes a step from the sequence.

A twenty-fold timing range

Exposure timing from 0.1 to 2 seconds reaches fast direct sensors at one end and phosphor plate or film technique at the other, which lets one protocol set serve mixed receptor types across surgeries.

Suited to urgent trauma assessment

Trauma work needs several angulations of the same tooth and a patient who often cannot or will not reposition. A carried unit with a legible readout fits that sequence, whether the presentation arrives mid-list or on an out-of-hours rota.

Greyscale range for restorative review

The higher kilovoltage setting yields a longer greyscale, which is what reading dense restorative material and surrounding tooth structure from a single image requires — the routine task in margin and secondary caries assessment.

An exposure envelope that spans the view set

Two kilovoltage settings and four milliamp steps let a protocol reach from paediatric anterior views up to molar bitewings on a large adult, with values agreed by your MPE and recorded as local diagnostic reference levels.

Tube focus specified at order.

Focus is offered at 0.4 mm or 0.8 mm, chosen at order alongside working distance and receptor type. Where resolving a fine fracture line is the diagnostic task, that choice is worth making deliberately with your Medical Physics Expert.

Carried by one clinician

At 1.7 kg and 110 × 140 × 165 mm, the unit sits comfortably within single-person handling for a full list, a community round or an out-of-hours call, alongside whatever else has to travel.

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-131 across the United Kingdom, including requesting the manufacturer's focus-to-skin, cone and filtration documentation with your quotation.

2.4-inch dot matrix display

Characters are formed from an illuminated cell grid across a 2.4-inch panel, giving generous character height on the control face.

Selectable tube voltage at 60 or 70 kV

Two kilovoltage settings support protocols that vary by region, patient build and the greyscale range a view requires.

Selectable tube current across four steps

Tube current is offered at 1.5, 2.0, 2.5 and 3.0 mA, giving a second exposure variable alongside kilovoltage and time.

0.1–2-second exposure timing

A twenty-fold span reaches direct digital sensors at the short end and phosphor plate or film technique at the upper limit.

Tube focus at 0.4 mm or 0.8 mm

Focus size is specified at order, one of the figures governing geometric sharpness at the receptor alongside working distance and receptor type.

30 kHz generator

High-frequency drive produces a steady output waveform through the exposure, supporting repeatable receptor density from one radiograph to the next.

130 mm published skin-to-cone distance

The manufacturer publishes a skin-to-cone figure; confirm with the manufacturer whether this is the focus-to-skin distance and which kilovoltage settings the supplied cone supports, and have your RPA review it.

FAQ

Frequently Asked Questions

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

Character height. A dot matrix panel builds characters from a cell grid, so a 2.4-inch screen carries figures large enough to read at working distance without the operator bringing their eye closer to the unit. That matters during positioning, when one hand is on the tube head and attention is on the receptor and the patient. Confirming the setting at a glance keeps the sequence moving.

Timing runs from 0.1 to 2 seconds, a twenty-fold span. The short end reaches the values fast direct digital sensors call for, and the upper end covers phosphor storage plates and intraoral film. Between those limits, the range covers anterior through molar regions across adult and paediatric protocols, with the specific values set by your Medical Physics Expert and recorded in your local diagnostic reference levels.

Periapical radiography is the standard intraoral means of assessing traumatic injury — root fracture, luxation, displacement and the position of an avulsed or intruded tooth. Trauma presentations often need several views of the same tooth at different angulations to resolve a fracture line, so a unit carried to a patient who is distressed and reluctant to reposition is genuinely useful. Exposure factors for each view still need to be justified individually under IR(ME)R 2017.

Bitewing and periapical views are the routine means of checking restoration margins, overhangs, secondary caries at the margin and the relationship of a restoration to the pulp. The higher kilovoltage setting produces a longer greyscale, which helps where dense restorative material and surrounding tooth structure have to be read from the same image. Agree on the setting for that view type with your Medical Physics Expert.

Raise this before ordering. UK dental guidance sets minimum focus-to-skin distances for intraoral equipment, and the required figure steps up for sets operating above 60 kV — commonly expressed as 100 mm at 60 kV and below, and 200 mm above 60 kV. This unit offers a 70 kV setting and publishes a 130 mm skin-to-cone figure. Ask the manufacturer to confirm whether that is the focus-to-skin distance or a cone measurement, whether a longer cone is available, and which kilovoltage settings the supplied cone supports. Have your Radiation Protection Adviser resolve it before the unit goes into service.

Focus is specified at order as 0.4 mm or 0.8 mm. Focus size governs geometric unsharpness at the receptor, so the choice interacts with your working distance, receptor type and the detail level clinicians need for endodontic and trauma work, where resolving a fine fracture line is the diagnostic task. Discuss it with your Medical Physics Expert and confirm the selection in writing on the order.

The pack is a DC 14.8 V 1600 mAh lithium unit, charged from AC 100–240 V with a DC 16.8 V output, so it runs on UK mains directly. The manufacturer does not publish an exposures-per-charge figure. Request it at quotation along with spare pack availability and pricing, particularly if the unit is intended for domiciliary rounds or for out-of-hours trauma cover.

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. These duties sit with the employer.

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, and your Radiation Protection Adviser sets the schedule. Warranty terms are set and issued by the seller or manufacturer, typically 12–24 months, with battery packs often warranted on a shorter cycle — confirm at quotation. Medigear.uk can arrange service cover and planned maintenance alongside supply.
