The Visionstar SJD-C10 platform is a dental X-ray system built on a Canon tube, offered in three mounting forms sharing the same electrical specifications. Tube voltage is 70 kV ±10%, anode current 7 mA ±20%, focal spot 0.7 mm and anode angle 19°, with exposure timing from 0.06 to 2.0 seconds under microprocessor control at a stated precision of one hundredth of a second. Leakage radiation is published at 0.007 mGy/h or less at one metre.

The duty cycle is the specification most worth understanding, and it is rarely published at all. A figure of 1 in 60 means that for every second of exposure the tube needs sixty seconds to cool before the next. A half-second exposure therefore carries a thirty-second wait; a two-second exposure carries two minutes. For single radiographs, that is invisible. For a full-mouth series of fourteen or more films it becomes the governor on how quickly the appointment moves, and it is worth planning around rather than discovering at the chair.

Beam quality is unusually well documented here too. Inherent filtration is stated at 2.1 mm aluminium or more, and half-value layer is published at 1.6 mm aluminium at 70 kV. HVL is the figure a Radiation Protection Adviser actually measures at critical examination, so seeing it on a data sheet is genuinely useful. It is worth noting that an HVL of 1.6 mm reads low against a stated inherent filtration of 2.1 mm or more — those two figures are worth reconciling with the manufacturer, though your RPA's own measurement is what governs.

The kilovoltage carries the usual consequence: at 70 kV the longer minimum focus-to-skin distance applies, and no cone length or distance is published. Medigear.uk can arrange supply, delivery, installation, commissioning and service cover across the United Kingdom.

Intraoral radiography carries the diagnostic load in UK general dentistry, and this platform covers it across three installation types. 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.

Operation at 70 kV produces a longer greyscale, which suits views where crestal bone, root surface and restorative material must be read from one image, and reaches a given receptor density in a shorter exposure. An exposure floor of 0.06 seconds sits comfortably within the range direct digital sensors call for.

Throughput is where the duty cycle enters clinical planning. A practice taking occasional single radiographs will never notice it; one running full-mouth series or endodontic sequences will find it sets the pace of the appointment. Building the cooling interval into appointment lengths avoids an operator waiting at the chair with a patient in position.

Beam quality documentation supports commissioning. A published half-value layer gives the Radiation Protection Adviser a figure to check against rather than establish from scratch, which shortens the conversation at critical examination even though their own measurement governs.

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 duty cycle you can plan against

Publishing a duty cycle at all is uncommon, and a stated figure lets a practice calculate its maximum exposure rate for long appointments rather than discovering the limit mid-series.

Half value layer published

HVL is the figure a Radiation Protection Adviser measures at critical examination, and having a manufacturer's figure to check against shortens that process.

Inherent filtration with margin

Inherent filtration stated at 2.1 mm aluminium or more comfortably exceeds the minimum commonly cited for intraoral equipment operating up to 70 kV.

A named tube on the floor-standing model

The Canon D-045 is identified by model on that variant, giving your RPA and service engineer a definite reference for beam quality data and replacement parts.

Timing resolved to a hundredth of a second

Microprocessor control at a stated hundredth-of-a-second precision supports fine optimisation of exposure values once your Medical Physics Expert has set them.

An exposure floor of 0.06 seconds

A very short minimum exposure sits within the range direct digital sensors need, keeping the moment a receptor must be tolerated brief.

Three mountings on one platform

Floor, trolley and wall forms share the same tube and electrical specification, so the installation type can follow the room without changing the imaging.

The Visionstar SJD-C10 platform gives UK dental practices a 70 kV X-ray system on a Canon tube with a 0.7 mm focal spot, 19° anode angle, 7 mA anode current, exposures from 0.06 to 2.0 seconds timed to a hundredth of a second, inherent filtration of 2.1 mm aluminium or more, a published half value layer and leakage of 0.007 mGy/h or less at one metre — in floor-standing, mobile trolley and wall-mounted forms. Four points need written answers before order: the cone specification and focus-to-skin distance, since 70 kV places the platform in the longer-distance band; the half value layer and inherent filtration reconciliation; the electrical specification for the wall variant; and the tube model on the trolley and wall forms. Check the 1 in 60 duty cycle against your longest appointments.

FAQ

Frequently Asked Questions

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

It sets your maximum exposure rate. For every second the tube is energised, it needs sixty seconds to shed the heat, so a half-second exposure carries a thirty-second wait and a two-second exposure carries two minutes. A single bitewing pair is unaffected; a full-mouth series or an endodontic sequence runs into it directly. Work the arithmetic against your longest appointment type before ordering, and ask what the unit does if an exposure is attempted inside the cooling period.

The focus-to-skin distance requirement. UK dental guidance applies a minimum distance from the focal spot to the patient's skin that steps up above 60 kV — commonly expressed as 100 mm at 60 kV and below, and 200 mm above it. This platform is specified at 70 kV, so the longer figure applies, and the data sheet publishes no focus-to-skin distance, cone length or field size. Request the cone specification and the resulting distance in writing, and give them to your Radiation Protection Adviser before commissioning.

Well documented, with one point to query. Inherent filtration at 2.1 mm aluminium or more comfortably exceeds the 1.5 mm equivalent minimum commonly cited for intraoral equipment to 70 kV, and publishing a half-value layer at all is welcome, since HVL is what a Radiation Protection Adviser measures rather than infers. The query is that 1.6 mm at 70 kV reads low for a beam already passing through 2.1 mm or more of aluminium. Ask the manufacturer to confirm both figures and their measurement conditions, and treat your RPA's measurement as deciding.

It follows the room, since all three share the same tube and electrical platform. The floor-standing form stands 1800 mm tall on a small footprint and suits a dedicated position. The mobile trolley moves between rooms — factor in door widths and turning space. The wall-mounted form is the lightest at 31 kg and keeps the floor clear, but fixes the installation and needs a structurally adequate wall. Check arm reach against a scale plan.

Its electrical rows. The floor and trolley versions publish power voltage, frequency, maximum power, current and fuse rating; the wall-mounted table gives none. Whether the figures are identical or simply were not repeated is not something to assume when equipment is being wired into a surgery. Request the full electrical specification in writing before an electrician quotes.

Named for one variant and not the others. The floor-standing model specifies a Canon D-045, while the trolley and wall forms list only Canon without a model number. The tube model is what your Radiation Protection Adviser and service engineer key beam quality data, expected test results and replacement parts off, so ask for written confirmation of the insert fitted to whichever variant you order, and request its datasheet.

Confirm before ordering. Supply is stated as AC 220 V without a tolerance band, drawing around 4 A behind a 6.3 A fuse. UK mains is nominally 230 V, and its tolerance extends higher still, so ask the manufacturer to confirm the unit is rated across the full UK supply range. The manufacturer describes the unit as tolerant of supply variation and not requiring a voltage regulator, which is a reasonable claim to test rather than assume. Have a qualified electrician specify the circuit.

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, complete a radiation risk assessment and designate the controlled area in local rules. 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. Each mounting form adds its own mechanical checks — column stability and balance, trolley castors and braking, or wall fixing integrity and arm drift. Warranty terms are set and issued by the seller or manufacturer, typically 12–24 months for this equipment class — confirm the term and the parts covered, including the tube, at quotation.
