The Visionstar SJD-211 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 housing is shaped to be held in the palm. A rounded body carries the control face on its flat rear panel and tapers to a conical nose, with the 220 mm depth placing the beam axis well forward of the operator's hand. A moulded strap runs across the rear for single-hand carrying. The practical effect is that the mass sits close to the wrist while the emitting end stands away from it, which is the arrangement that lets an operator hold a position steadily through the exposure.

The control face carries a monochromatic readout. Character formation in high contrast against a plain background holds legibility under the direct beam of an operating lamp and at the oblique angles an operator reads from while the unit is positioned, so the active setting is confirmed without shading the panel or repositioning the head.

Two kilovoltage settings, four milliamp steps and a twenty-fold timing range give a Medical Physics Expert scope when writing protocols under the optimisation duty in IR(ME)R 2017. 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. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation and service cover for the SJD-211 across the United Kingdom.

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-211 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.

Emergency and unscheduled care is a natural fit. A patient presenting in pain with facial swelling needs a diagnosis in a short appointment, and a periapical view is usually what settles it — periapical radiolucency, loss of lamina dura and widened periodontal ligament space point to an apical source, while tracing a gutta-percha point placed in a sinus tract identifies which tooth is responsible. Distinguishing an apical abscess from a periodontal one changes the treatment plan completely, and the radiograph is frequently the deciding evidence.

Practices running phosphor storage plates are well served by the timing range. Plates suit surgeries that want a flexible, cable-free receptor and can accommodate a scanning step, and they are widely used in UK community and domiciliary settings where a rigid sensor and its cable are awkward.

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.

Mass at the wrist, beam well forward.

A rounded palm-held body with a 220 mm depth keeps the weight close to the wrist while the emitting end stands away from it. That distribution is what lets an operator hold an alignment steadily through the exposure across a full list.

A readout confirmed without repositioning

High-contrast character rendering holds legibility under an operating lamp and at oblique angles, so the setting is checked before triggering with the unit already in position and one hand occupied.

Suited to the emergency appointment

A carried unit that reaches a patient in pain, combined with periapical views that identify an apical source and trace a sinus tract, fits the short unscheduled appointment where a diagnosis has to be reached quickly.

Timing range that covers plate technique

The 0.1 to 2 second span reaches phosphor storage plate exposures at the longer end and direct sensor values at the short end, so one unit serves a surgery running either receptor.

Exposure factors that actually vary

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 lamina dura and early periapical change is the diagnostic task, that choice is worth making deliberately.

Carried by one clinician

At 1.7 kg, 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-211 across the United Kingdom, including requesting the manufacturer's focus-to-skin, cone and filtration documentation with your quotation.

Monochromatic readout

A high-contrast character display presents the active exposure settings and machine state on a plain background.

Palm-held rounded housing

The body is shaped to sit in the palm, with the control face on the flat rear panel and a tapered nose forward of the hand.

220 mm housing depth

Published depth places the emitting end well forward of the operator's hand while the mass stays close to the wrist.

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 storage 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.

Membrane control keypad

A sealed key array gives positive tactile feedback under glove and presents a flat, wipeable control face for routine decontamination.

Ready and exposure indicators

Illuminated status markers signal machine state through the exposure cycle, giving visual confirmation at each stage.

Side-mounted exposure release

The exposure control sits on the side of the housing, within reach of the carrying hand while the head is held in position.

DC 14.8 V 1600 mAh lithium battery

An integrated lithium pack powers the unit away from a fixed power position, charged from AC 100–240 V with a DC 16.8 V output and a 100–300 VA rating.

Moulded hand strap

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

FAQ

Frequently Asked Questions

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

High-contrast character rendering against a plain background, which holds legibility under an operating lamp and at the oblique viewing angles an operator reads from while the unit is held in position. The active setting is confirmed before the exposure without shading the panel by hand or bringing the unit closer to the eye. On a machine where kilovoltage, current and time are each operator-selected, reading all three at a glance is worth having.

The body is rounded to sit in the palm, with the control face on the flat rear panel and a tapered nose forward. At 220 mm deep, the emitting end stands well away from the hand while the mass stays close to the wrist. That distribution is what allows an operator to hold an alignment steadily through the exposure, and it matters most for staff taking twenty or thirty radiographs across a working day.

Yes. The 0.1 to 2 second timing range comfortably covers phosphor plate technique at the longer end, and the two kilovoltage settings allow the exposure to be matched to plate speed. Phosphor plates suit practices that want a flexible, cable-free receptor and are willing to accept a scanning step between exposure and image. Plate sizes, the scanner and its software are separate purchases — confirm the pairing at order so exposure protocols can be set at commissioning.

Periapical radiography is the standard intraoral means of assessing an apical abscess. A periapical radiolucency, loss of lamina dura and widening of the periodontal ligament space are the findings clinicians look for, and a gutta-percha point placed in a sinus tract can be traced radiographically to its source. Distinguishing an apical abscess from a periodontal one changes the treatment entirely, so the view is often what settles the diagnosis in an emergency appointment. Each exposure still requires justification under IR(ME)R 2017.

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 — resolving lamina dura and early periapical change rewards geometric sharpness. 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 emergency cover outside normal hours.

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.
