The Visionstar SJD-PX02 is a battery-powered dental X-ray generator built around a Canon tube insert, in a pistol-grip body weighing 1.8 kg. The generator is DC high-frequency, running an inverter circuit at 100 kHz, with tube voltage fixed at 60 kV and tube current fixed at 2 mA. Focal spot size is 0.7 mm, and the target angle is 16°.

Two published figures set this data sheet apart, and both belong in the specification conversation. Total filtration is stated at 1.5 mm aluminium — the figure a Radiation Protection Adviser actually works from, and one commonly given as the minimum for intraoral sets operating up to 70 kV. It is worth noting that this is the minimum rather than a margin above it, so the half-value layer measurement at critical examination remains the confirming step.

The X-ray field is stated at 50 mm, round. UK dental guidance caps the beam diameter at the patient's skin, commonly expressed as 60 mm for a round field, so 50 mm sits inside that limit. The same guidance recommends rectangular collimation for intraoral radiography, because shaping the beam to the receptor cuts the volume of tissue irradiated substantially. Ask the manufacturer whether a rectangular collimator is available for this unit and whether it works with your receptor holders, and take your Medical Physics Expert's view on it as part of your optimisation work.

Exposure timing runs from 0.05 to 1.35 seconds in 0.01-second increments. That granularity is unusual and genuinely useful: it gives an MPE fine control when setting values by region, patient build and receptor speed, instead of jumping between coarse steps.

The unit carries a large LCD, a boot self-check that reports faults automatically at power-up, and a stated compatibility with digital sensors. The manufacturer publishes a two-year warranty. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation and service cover for the SJD-PX02 across the United Kingdom.

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-PX02 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.

What distinguishes this unit clinically is how much of its beam specification is published. Optimisation under IR(ME)R 2017 is the duty to keep doses as low as reasonably practicable while producing images adequate for the diagnostic task, and it runs on figures — total filtration, field size, exposure factors, receptor speed. A data sheet that states total filtration and field dimensions lets a Medical Physics Expert engage with the equipment before it arrives rather than after commissioning.

The 0.01 second exposure step is the practical expression of that. Roughly 130 discrete settings between 0.05 and 1.35 seconds means a protocol can be tuned closely by region, patient build and receptor speed, and optimised downwards in small increments after an image quality audit rather than in coarse jumps.

Collimation is the one specification that deserves scrutiny before purchase. A 50 mm round field sits within the beam diameter limit UK guidance sets at the skin, but rectangular collimation is what the same guidance recommends, because shaping the beam to the receptor removes a substantial share of irradiated tissue. Practices committed to dose optimisation, and services answerable for paediatric exposures in particular, should settle the collimator question at specification.

Community dental services and special care teams need equipment one clinician can carry. At 1.8 kg, the unit travels, 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 that UK practices work to, alongside HSE enforcement of IRR17.

Total filtration on the data sheet

Beam quality assessment works from total filtration, and this unit publishes 1.5 mm aluminium. Your Radiation Protection Adviser starts commissioning from a known position, with the half-value layer measurement as confirmation.

Field size stated, not left to enquiry.

A published 50 mm round field lets the collimation conversation happen at specification, which is when a rectangular collimator can still be specified and matched to your receptor holders.

Exposure control in hundredths of a second

Around 130 discrete settings between 0.05 and 1.35 seconds give a Medical Physics Expert fine control when setting local diagnostic reference levels and when optimising downwards after an audit.

A tube insert your RPA can look up

The Canon insert is a named component with published characteristics, giving service engineers and radiation protection advisers a definite reference for beam quality data and parts.

A published two-year term

The manufacturer states a two-year warranty openly. Confirm at quotation what sits inside it — particularly the battery and LCD assembly — and the UK parts and labour arrangements.

Daily status at switch-on

A boot self-check reports faults automatically at power-up, giving a status indication that sits alongside the documented quality assurance programme IRR17 requires.

Pistol grip at 1.8 kg

A vertical grip carries weight through the palm and forearm with the beam axis forward of the hand, supporting a steady hold across a full list.

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-PX02 across the United Kingdom, including requesting collimator options and tube documentation with your quotation.

1.5 mm Al total filtration

Total filtration is published rather than inherent filtration alone, giving the Radiation Protection Adviser the figure beam quality assessment works from.

50 mm round X-ray field

Published field diameter at the working distance; confirm rectangular collimator availability and receptor holder compatibility at order.

0.05–1.35 second exposure range in 0.01 s steps

Roughly 130 discrete settings allow close tuning of exposure by region, patient build and receptor speed.

Canon tube insert

The tube assembly is supplied by an established manufacturer with published characteristics, giving a definite reference for servicing and part replacement.

0.7 mm focal spot

Published focal spot size, one of the figures governing geometric sharpness at the receptor alongside working distance and receptor position.

16° target angle

Published anode target angle, relevant to field coverage and to the intensity distribution across the beam.

60 kV fixed tube voltage

Operation at a fixed 60 kV sits within the established kilovoltage range for intraoral dental radiography.

2 mA fixed tube current

Holding tube current constant means the exposure product is governed entirely by time, which simplifies protocol design and audit.

DC high-frequency generator at 100 kHz

Inverter operation produces a near-constant potential waveform, delivering steadier output per exposure and a beam carrying proportionally fewer low-energy photons.

Large LCD display

A high-contrast panel presents the active exposure value and machine state on the rear control face.

Boot self-check with automatic fault reporting

A self-diagnostic routine runs at power-up and reports detected faults, giving a daily equipment status indication at switch-on.

16.8 V lithium battery

A lithium pack powers the unit away from a fixed power position; capacity in milliamp hours is not published, so request it and the exposures-per-charge figure at quotation.

Pistol-grip body at 1.8 kg

A vertical handgrip places the beam axis forward of the hand while the mass sits close to the wrist, supporting a steady hold through the exposure.

Two-year manufacturer warranty

A published term for this equipment class; confirm the parts covered, the battery and LCD position, and UK service arrangements at quotation.

FAQ

Frequently Asked Questions

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

It means your Radiation Protection Adviser starts from a known figure rather than an inherent value that needs to be added to. Total filtration describes the whole beam path and is what beam quality assessment works from; the commonly cited minimum for intraoral sets operating up to 70 kV is 1.5 mm aluminium equivalent. This unit states exactly that, which is compliant with the minimum rather than comfortably above it. Your RPA will still measure the half-value layer at critical examination, and that measurement is the one that counts.

Yes, and this is the most useful question to raise before ordering. UK guidance caps the beam at the patient's skin — commonly stated as 60 mm diameter for a round field — so 50 mm is within the limit. But the same guidance recommends rectangular collimation, because matching the beam shape to the receptor removes a substantial portion of the irradiated tissue and reduces patient dose accordingly. Ask whether a rectangular collimator is available for this unit, whether it fits your receptor holders, and what it does to the working field. Then take your Medical Physics Expert's view. Medigear.uk can arrange for those answers to be requested with your quotation.

Fine control. A range of 0.05 to 1.35 seconds in hundredth-of-a-second increments gives roughly 130 discrete settings, so exposure values can be tuned closely to region, patient build and receptor speed rather than rounded to the nearest coarse step. That is directly useful when your Medical Physics Expert sets local diagnostic reference levels and when you optimise downwards after an image quality audit.

The manufacturer publishes a two-year term. Warranty terms are still set and issued by the seller or manufacturer, so confirm at quotation what falls inside it — specifically whether the battery and the LCD assembly are covered for the full two years or on a shorter cycle, and what the arrangements are for parts and labour in the UK.

As manufacturer marketing positioning, not a UK regulatory statement. Every dental X-ray generator emits ionising radiation by design. What actually determines dose in your surgery is the combination of exposure factors, receptor speed, collimation, total filtration, operator position and shielding — and collimation is the lever this data sheet invites you to examine. Have your Radiation Protection Adviser and Medical Physics Expert measure and record the real figures for your installation.

A named, identifiable component. Beam quality data, half-value layer figures, expected radiological test results and replacement part sourcing are all key off the tube model, so a tube from an established manufacturer gives your RPA and service engineer a definite reference point. Ask for the tube datasheet with your quotation.

The manufacturer states compatibility with digital sensors generally, and the 0.05 second lower limit reaches the short exposures that fast direct sensors require. Sensor hardware, sizing and imaging software remain separate purchases. Confirm the specific sensor and software pairing at order so exposure protocols can be set and checked at commissioning, and so any rectangular collimator selected suits the receptor size you actually use.

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. The boot self-check gives a daily status indication at switch-on but supplements that programme rather than forming part of it. Medigear.uk can arrange service cover and planned maintenance alongside supply.
