Visionstar SJD-C19

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-C19 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.

Multi-view sessions are where the published heat capacity becomes relevant. Endodontic treatment generating four or more views in one appointment, a full-mouth periapical survey, a trauma presentation needing several angulations of the same tooth, or a prosthodontic workup covering multiple abutments all take exposures in close succession. A stated anode heat capacity gives a practice something definite to plan against, and the manufacturer's duty cycle guidance is the natural follow-up question for services that routinely run those sessions.

Dose optimisation is served by the filtration position and the exposure granularity together. A published 1.6 mm aluminium total, broken into inherent and fixed added components, sits above the minimum commonly cited for setups up to 70 kV and gives the Radiation Protection Adviser a clear starting point. Timing in hundredth-of-a-second steps from 0.01 seconds, then lets the Medical Physics Expert set values closely by region, patient build and receptor speed, and optimise downwards in fine increments after an image quality audit.

Operator protection needs its own arrangement regardless of the internal shielding. Leakage from the housing and backscatter from the patient are separate exposures, and the second is what the operator's position and an external shield address. That belongs in the RPA's assessment before the unit enters service.

Community dental services and special care teams need equipment one clinician can carry, and at 2.0 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.

Filtration documented in full.

Total filtration is published at 1.6 mm aluminium and broken into 0.8 mm inherent plus 0.8 mm fixed added. That level of detail is what a Radiation Protection Adviser needs, and the total sits above the minimum commonly cited for setups up to 70 kV.

Added filtration described as fixed

Fixed added filtration is not a component that can be omitted or mislaid at service, which removes one variable from the beam quality picture over the life of the unit.

Heat capacity you can plan against

A stated 4300 joule anode capacity gives practices running long multi-view sessions something definite to work with, and a specific question to put to the manufacturer about duty cycle.

Exposure control in hundredths of a second

Timing from 0.01 to 1.6 seconds in hundredth-of-a-second increments gives a Medical Physics Expert fine control when setting local diagnostic reference levels and when optimising after an audit.

Pre-programmed values for chairside speed

Programmed exposure times make routine selection quick at the chair while leaving the underlying granularity available. Confirm at order whether the programmed values can be edited to your agreed protocols.

Microprocessor-regulated exposure

Exposure is controlled electronically rather than by mechanical timing, which supports consistency between one exposure and the next across a session.

Leakage addressed inside the housing

An internal lead shield reduces dispersed radiation escaping the tube housing. Treat it as one part of the protection picture, alongside the external shielding and operator position your RPA specifies.

UK supply, commissioning and service through one route

Medigear.uk can arrange listing, supply, delivery, installation, commissioning, staff familiarisation, service cover, planned maintenance, shielding accessories and quotations for the SJD-C19 across the United Kingdom.

D-045 stationary anode tube

A named fixed-anode insert, giving your Radiation Protection Adviser and service engineer a definite reference for beam quality data and parts.

4300 J anode heat capacity

Published heat capacity, the figure that governs how many exposures can be taken in close succession before a cooling interval.

1.6 mm Al total filtration

Published as 0.8 mm inherent plus 0.8 mm fixed added, sitting above the minimum commonly cited for intraoral sets operating up to 70 kV.

Internal lead shield

Housing shielding intended to reduce dispersed radiation; external backscatter protection remains a separate matter for your RPA.

0.4 mm focal size

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

12.5° target angle

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

0.01–1.6 second exposure range in 0.01 s steps

Hundredth-of-a-second increments across the full range, adjusted through up and down arrows on the control face.

Pre-programmed exposure values

Stored settings speed routine selection at the chair; confirm editability at order so agreed protocols can be loaded.

Microprocessor exposure control

Exposure is regulated electronically, supporting consistency between successive exposures across a session.

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 inverter generator

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

Built-in DC 24 V lithium-ion battery

An integrated pack charged from AC 100–240 V; capacity and the replacement procedure are not published, so request both at quotation.

180 × 147 × 138 mm at 2.0 kg

Published dimensions and weight are the figures that determine storage arrangements and single-person handling across a list.

The Visionstar SJD-C19 gives UK dental teams a 2.0 kg battery-powered X-ray generator built around a D-045 stationary anode tube with 4300 joule heat capacity, a 0.4 mm focal size and 12.5° target angle, 60 kV / 2 mA fixed output from a microprocessor-controlled high-frequency inverter, published total filtration of 1.6 mm aluminium broken into inherent and fixed added components, and exposure timing from 0.01 to 1.6 seconds in hundredth-of-a-second steps with pre-programmed values. It fits NHS and private general practice, endodontics and prosthodontics running multi-view sessions, paediatric and special care dentistry, community dental services and outreach programmes. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation, service cover, planned maintenance and shielding accessories across the United Kingdom, and can arrange for the manufacturer's tube datasheet, duty cycle guidance, half-value layer data and battery documentation to accompany your quotation for your Radiation Protection Adviser's review.
