Blackstone HS-X201

Community dental clinics and hospital outpatient departments that run a dedicated X-ray room use the HS-X201 as the entire station. The patient takes the pneumatic seat, the operator raises it until the head sits level with the cone, and the arm brings the tubehead into position for a periapical or bitewing view. Remote exposure lets the operator step back before every radiograph.

Screening programmes in schools and workplaces set the unit up in a borrowed room for the day, with the base in mobile mode, because the station needs floor space and a 220 V supply. Dental schools use a fixed station for teaching radiography, where every student practises positioning on the same seat and arm.

General practices with a separate X-ray corner use it to keep radiography out of the surgeries, freeing the dental chairs for treatment while the next patient is imaged. Endodontic working-length checks and implant review images follow the same routine on the seat. Orthodontic and paediatric clinics use the pneumatic lift to bring smaller patients up towards the cone before each bitewing.

Dental nurses prepare the film or sensor and the holder, and the clinician chooses the exposure on the touch-key panel. Practices still processing film can keep doing so with daylight-developing film, and those using a digital sensor system connect it in the usual way. The 0.8 mm focal spot serves work that depends on fine detail, such as root canal files.

It is not the unit for radiographs in the dental chair, for home visits,s or for panoramic imaging, and its supply is rated at 220 V, 50 Hz.

A seat built into the station

The column carries a pneumatic patient seat beneath the arm, so radiography happens without a dental chair. Any room with floor space and a 220 V supply becomes an X-ray station.

Height set by pneumatic lift

The seat rises and lowers pneumatically to bring the patient's head level with the cone. The operator sets the height before each radiograph.

Distance for the operator

Remote exposure lets the operator leave the beam area before each radiograph. Stepping back is built into every exposure, since the trigger sits away from the tubehead.

Mobile or fixed

The base runs in mobile mode for moving between rooms and in fixed mode for a permanent station. One unit can serve a screening day and then return to its corner.

Two focal spot sizes

A 0.8 mm focal spot is offered alongside the 1.5 mm size. The finer spot suits detail work at the same 60 kV, 8 mA output.

Supply alarm and voltage protection

A low-voltage alarm warns of a weak supply, and high-voltage protection guards the generator. Both run under the same microcomputer control as the timer.

Leakage of 0.002 mGy/h at one metre

One metre from the housing, leakage reads 0.002 mGy/h at most, so people near the station receive very little stray radiation.

One press per exposure setting

Touch keys set the exposure in a single press, so staff move from one radiograph to the next without stepping through menus.

Film today, sensors tomorrow

Daylight-developing film and digital intraoral imaging systems both work with it. A practice can change its receptor without changing the X-ray.

Floor-standing column and arm

A floor-standing column carries the articulated arm and tubehead above the patient seat.

Pneumatic patient seat

The patient seat rises and lowers on a pneumatic lift.

Mobile and fixed base modes

The base runs in mobile mode or fixed mode.

60 kV tube voltage

The generator applies 60 kV across the tube.

8 mA tube current

The tube draws 8 mA during exposure.

1.5 mm or 0.8 mm focal spot

Focal spot size is 1.5 mm or 0.8 mm.

2.5 mm Al total filtration

The beam passes through 2.5 mm Al of total filtration.

Exposure time from 0.2 to 4 seconds

Exposure runs for any time between 0.2 and 4 seconds.

Touch-key microcomputer control

Touch keys on the control panel set each exposure in one press under microcomputer control.

Remote-controlled exposure

Exposure is triggered remotely, away from the tubehead.

Low-voltage alarm

An alarm warns when the supply voltage drops too low.

High-voltage protection

High-voltage protection guards the generator circuit.

Leakage radiation at one metre

Housing leakage is capped at 0.002 mGy/h, measured one metre away.

220 V, 50 Hz, 1 kVA supply

Mains input is 220 V ± 10% at 50 Hz, with a 1 kVA rating.

Film and digital imaging compatibility

Daylight-developing dental film and digital intraoral imaging systems both serve as receptors.

The HS-X201 suits a clinic that wants a self-contained intraoral X-ray station, whether in a dedicated room, a screening venue, or a teaching space. Its case is workflow: the patient sits on the unit's own pneumatic seat, the operator exposes remotely from a distance, and the base moves or stays fixed. Four limits matter most. No CE or UKCA position is evidenced for this model. Radiographs happen on its own seat, so imaging in the dental chair needs a different source. Power is 220 V, 50 Hz only. Film or a sensor system is still required, and the focal spot comes in 1.5 mm or 0.8 mm.
