The Visionstar SJD-C10L is a mobile dental X-ray unit on a wheeled base, running at 70 kV ±10% at 7 mA ±20% from a Canon tube with a 0.7 mm focal spot and 19° anode angle. Exposure timing runs from 0.06 to 2.0 seconds under microprocessor control, with a published duty cycle of 1 in 60, inherent filtration of 2.1 mm aluminium or more, a half-value layer of 1.6 mm aluminium at 70 kV and leakage radiation of 0.007 mGy/h or less at one metre. Supply is AC 220 V at 900 VA behind a 6.3 A fuse.

Mobility changes the regulatory work rather than reducing it. Under IRR17, the controlled area is designated by the employer's radiation risk assessment, so a unit serving more than one surgery means every location it will be used in must be assessed and named in local rules. Wall construction, adjacent occupancy, operator position and the door line differ between rooms, so a unit compliant in one surgery is not automatically compliant next door. Settle that list with your Radiation Protection Adviser before the unit arrives.

The practical side follows the same logic. A tube head on an extending arm shifts the centre of gravity as the arm moves, so castor locking and guidance on extension during transit both matter. Each room needs a suitable socket in a sensible position, since a trailing mains lead across a surgery floor is a hazard in itself.

The manufacturer describes the unit as tolerant of supply variation without a voltage regulator, which matters where the unit meets a different circuit in every room. 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 a mobile unit puts that capability into more than one surgery without duplicating equipment. The SJD-C10L 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 configuration suits practices with radiographic demand spread across several rooms but not concentrated enough in any one to justify a unit per surgery — a two- or three-surgery practice taking a moderate number of radiographs daily is the natural case.

Operation at 70 kV produces a longer greyscale, useful where crestal bone, root surface and restorative material must be read from one image. An exposure floor of 0.06 seconds sits within the range direct digital sensors call for.

Session planning asks for realism. The cooling interval and the time taken to move the unit both consume clinical time, and they stack rather than overlap when one person does both. Practices running full-mouth series across more than one surgery should test the arithmetic against an actual session.

The regulatory work scales with the number of rooms rather than units. Every surgery on the permitted list needs assessing and naming in local rules, and that list is worth keeping short and definite.

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.

One unit serving several assessed rooms

Radiographic capability reaches more than one surgery without a unit for each, provided every room is assessed and named in local rules.

Supply tolerance that suits changing circuits

The manufacturer describes the unit as unaffected by supply variation and not requiring a voltage regulator, which matters more where the unit meets a different circuit in every room.

A published duty cycle to plan against

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

Half value layer published

HVL is the figure a Radiation Protection Adviser measures at critical examination, so a manufacturer's figure to check against shortens the commissioning conversation.

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.

An exposure floor of 0.06 seconds

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

Timing resolved to a hundredth of a second

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

UK supply, installation and service through one route

Medigear.uk can arrange listing, supply, delivery, installation, commissioning, staff familiarisation, service cover, planned maintenance and quotations across the United Kingdom.

Wheeled base for use across rooms

The unit moves between surgeries on castors — confirm locking, stability with the arm extended, and threshold and floor covering limits.

70 kV ±10% tube voltage

Fixed kilovoltage above the 60 kV threshold, determining which minimum focus-to-skin distance applies.

7 mA ±20% anode current

Published anode current with its stated tolerance band.

0.7 mm focal spot

Published focal spot size, one of the figures governing geometric sharpness at the receptor.

19° anode angle

Published anode angle, influencing the effective focal spot at the receptor and the intensity distribution across the field.

Duty cycle 1 in 60

Published cooling requirement — sixty seconds of rest for each second of exposure.

Half-value layer: 1.6 mm Al at 70 kV

Published HVL — reads low against the stated inherent filtration; ask the manufacturer to reconcile both.

Inherent filtration ≥2.1 mm Al

Published inherent filtration, above the minimum commonly cited for intraoral equipment to 70 kV; total filtration is not stated separately.

Exposure range 0.06–2.0 seconds

A wide span reaching direct sensors at the short end, timed to a stated hundredth of a second.

Leakage 0.007 mGy/h or less at one metre

Published housing leakage figure, used by the RPA in assessing controlled areas.

Canon tube

A Canon insert — the model number is not stated for this variant; request written confirmation and the datasheet.

900 VA supply behind a 6.3 A fuse

Published power rating and fuse size; drawing around 4 A — confirm each permitted room has a suitable socket.

Supply variation tolerance

Described as not requiring a voltage regulator, which suits a unit plugged into a different circuit in each room.

Published dimensions 1060 × 400 × 370 mm at 50 kg

Confirm whether these are unit or packed figures, and request standing height, base footprint, arm reach and net weight separately.

The Visionstar SJD-C10L gives UK dental practices a mobile X-ray unit on a wheeled base, running 70 kV and 7 mA from a Canon tube with a 0.7 mm focal spot, 19° anode angle, exposures from 0.06 to 2.0 seconds, a published duty cycle of 1 in 60, 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. Its defining requirement is regulatory rather than mechanical: every room the unit is used in must be assessed and named in local rules. Four further points need written answers before order — the cone specification and focus-to-skin distance, since 70 kV places the unit in the longer-distance band; the half-value layer and inherent filtration reconciliation; the tube model; and whether the published dimensions describe the unit or the crate. Medigear.uk can arrange supply, delivery, installation, commissioning, staff familiarisation, service cover and planned maintenance across the United Kingdom.

FAQ

Frequently Asked Questions

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

That every room is part of the assessment, not just the unit. The controlled area is designated through the employer's radiation risk assessment, and where equipment moves, that assessment must cover each location it will be used in — wall construction, what lies beyond, occupancy of adjacent spaces, operator position and door security. Local rules then name the permitted rooms. A practice expecting to use a mobile unit wherever convenient has misread the format: what it buys is one unit across a defined, assessed set of rooms.

Ask, because the figures are not published. A wheeled base carrying a column and an extending arm shifts its centre of gravity as the arm moves out, and stability depends on footprint, mass distribution and whether the castors are locked. Request the stability envelope, confirmation that the castors lock, and guidance on whether the arm should be retracted before moving. Ask about threshold and floor covering limits too, since a 50 kg unit crossing a door strip behaves differently from one on vinyl.

Worth clarifying before planning around them. The data sheet gives 1060 × 400 × 370 mm alongside a gross weight, and gross weight normally describes a packed item — so these may be shipping figures. Request standing height, base footprint, arm reach at full extension and net weight separately. All four bear on which rooms the unit can serve and how it is stored.

The minimum focus-to-skin distance. UK dental guidance sets that minimum higher above 60 kV — commonly 100 mm at 60 kV and below, 200 mm above — and this unit is specified at 70 kV. No focus-to-skin distance, cone length or field size appears on the data sheet. Request the cone specification and resulting distance in writing for your Radiation Protection Adviser.

Well documented, with one query. Inherent filtration at 2.1 mm aluminium or more exceeds the 1.5 mm equivalent minimum commonly cited for intraoral equipment to 70 kV, and a published half-value layer is useful since that 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; your RPA's measurement governs.

The tube is listed as Canon without a model number, so request written confirmation and its datasheet — your RPA and service engineer work from the tube model. On supply, the unit draws around 4 A at 900 VA behind a 6.3 A fuse from a stated 220 V. UK mains is nominally 230 V with tolerance extending higher, so confirm the unit is rated across the full UK range, and check each permitted room has a socket positioned so the lead does not cross a working area.

It adds to the time the unit is unavailable rather than overlapping with it. A duty cycle of 1 in 60 means sixty seconds of cooling for each second of exposure, so a half-second exposure carries a thirty-second wait. Moving the unit to the next surgery takes its own time on top, and the two do not cancel out if one operator does both. Work the arithmetic against a realistic session rather than a best case.

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 controlled areas in local rules — covering every room a mobile unit will be used in. 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 at installation. A wheeled unit adds its own checks — castor condition and locking, base and column integrity, arm balance and drift, and a frequently handled mains lead. Warranty terms are set by the seller or manufacturer, typically 12–24 months — confirm the term and whether the tube is covered.
