The number in a CT scanner's name usually describes what the detector acquires. On this platform the acquisition and the reconstruction are described separately, and both are worth understanding.

Acquisition runs across sixteen detector rows. Each row carries 720 elements for a total of 11,520 across a detector width of 12.8 mm, and the data acquisition rate reaches 1,320 views per rotation. Collimation is offered at 2 × 0.8 mm, 12 × 0.8 mm and 16 × 0.8 mm, giving a sub-millimetre element pitch through the acquisition. Where the thirty-two-slice option is present, helical reconstruction returns up to thirty-two reconstructed slices from those sixteen acquired rows, which affects the density of the reformatted dataset available for review.

The gantry is built compactly. The aperture measures 65 cm, focus to isocentre is 511 mm and focus to detector 900 mm, and the scan field of view spans 450 mm with reconstruction available from 50 to 450 mm. Rotation times run at 0.75, 1, 1.5 and 2 seconds for a full rotation, and pitch is selectable from 0.5 to 1.5. Tilt is digital, and the gantry runs on a low-voltage slip ring.

The tube assembly stores 3.5 MHU of anode heat with oil cooling, dissipating up to 3 kW continuously, and offers two focal spots at 0.4 × 0.7 mm and 0.6 × 1.3 mm. The anode turns at 3,000 rpm on a 50 Hz supply or 3,600 rpm at 60 Hz, and maximum focal spot power reaches 28 kW.

Image quality figures follow from that geometry. Spatial resolution reaches up to 15 line pairs per centimetre at zero percent MTF, and low contrast resolution is stated as 3.0 mm at 0.3 percent measured on a 20 cm Catphan phantom with a central CTDI no greater than 40 mGy.

Reconstruction runs at up to 10 images per second into a 512, 768 or 1024 matrix, with a 1024 by 1024 display matrix and layouts of one, four, nine or sixteen images. The console holds 8 GB of memory with storage for more than 750,000 images.

Patient handling and positioning are supported by sagittal and transverse localisers able to perform posteroanterior and lateral scans, laser positioning lamps, and gantry control panels carrying couch movement, fast couch movement, emergency stop and laser controls. The couch is supplied fixed or vertically moveable, with scannable range of at least 1,200 mm on the fixed couch and at least 1,380 mm on the vertically moveable version. Multilingual AutoVoice delivers a standard set of patient instructions before, during and after scanning.

Diagnostic interpretation remains with the reporting radiologist, and exposure decisions with the operator and the employer's dose framework. The tube condition and slice count, the software version, the reconstruction and couch options, the regulatory documentation and the service history are provided by the seller at quotation, with CE marking documentation and the declaration of conformity issued by the manufacturer or held by the seller.

Routine head computed tomography is served by sub-millimetre collimation at 16 × 0.8 mm and a 450 mm scan field, with reconstruction available from 50 mm for a tightly framed study.

Chest and abdominal imaging runs across the full sixteen rows, with pitch selectable from 0.5 to 1.5 according to the coverage and dose the study calls for.

Musculoskeletal and spine work benefits from the 0.4 × 0.7 mm fine focal spot and spatial resolution reaching 15 line pairs per centimetre at zero percent MTF.

Emergency department imaging is supported by localisers performing posteroanterior and lateral scans and by gantry-side couch controls for quick positioning.

Reformatted review is supported where the thirty-two-slice helical reconstruction option is present, since a denser reconstructed dataset carries more detail into multiplanar review.

Departments with constrained rooms are served by a compact gantry at a 65 cm aperture and a fixed-height couch option, which reduces what a room has to accommodate.

Services scanning patients who need consistent instruction are supported by multilingual AutoVoice, which delivers the same guidance before, during and after every scan.

Sixteen Rows Across 11,520 Elements

The detector carries 720 elements in each of sixteen rows over a 12.8 mm width, sampling at up to 1,320 views per rotation.

Denser Reconstruction Where the Option Is Present

Helical reconstruction returns up to thirty-two slices from the sixteen acquired rows, which carries more detail into reformatted review.

Sub-Millimetre Collimation

Collimation at 2 × 0.8 mm, 12 × 0.8 mm and 16 × 0.8 mm gives a sub-millimetre element pitch through the acquisition.

A Fine Focal Spot for Detail

Focal spots of 0.4 × 0.7 mm and 0.6 × 1.3 mm support spatial resolution reaching 15 line pairs per centimetre at zero percent MTF.

Oil Cooling Through the List

The tube stores 3.5 MHU of anode heat with oil cooling and dissipates up to 3 kW continuously.

A Compact Gantry Footprint

A 65 cm aperture with focus to isocentre at 511 mm keeps the gantry compact for the room it occupies.

Pitch Set to the Study

Selectable pitch from 0.5 to 1.5 lets coverage and sampling density be set to the examination.

Localisers in Two Planes

Sagittal and transverse localisers perform posteroanterior and lateral scans before the acquisition begins.

Instructions Delivered the Same Way Every Time

Multilingual AutoVoice gives a standard set of patient commands before, during and after scanning.

Positioning Controlled at the Gantry

Couch movement, fast movement, laser and emergency stop controls sit on the gantry panels alongside the console controls.

Documentation Established Before Order

Tube condition, slice count, fitted options and the regulatory documentation are provided by the seller at quotation, so what a buyer receives is established in writing.
