COMPONENT DETAILS:

Aquilion 16 is a whole-body Computed Tomography (CT) scanner that provides uncompromised image quality and outstanding clinical performance. Its flexibility and performance are changing the way radiology triages patients through the Emergency Department.
Its Quantum detector provides true isotropic resolution in the small field of view with 0.5 mm the industry’s thinnest slice width. This enables the user to scan in one plane, reducing radiation while selecting the desired thickness for viewing. Aquilion’s Quantum detector is the only detector to provide three slice-width combinations — 16x0.5, 16*1 and 16x2 mm, and it achieves the industry’s best low-contrast resolution at 0.5-second scan speed.
The combination of a high-speed scanner and an extremely powerful, high- voltage generator meets every diagnostic requirement Solid-slate, multi-row detectors and optimal reconstruction techniques ensure high-quality images. A high-performance CPU, large color monitors, hybrid keyboard and refined Graphic User Interface (GUI) make the operating environment highly efficient.

SOFTWARE DESCRIPTION

ASPIRE CI: Continuous Imaging
Continuous Imaging provides the ability to view a helical scan at 8 frames per second (512 x 512 matrix) or 12 frames per second (256 x 256 matrix). This immediate image feedback allows the operator to more rapidly assess if a scan is proceeding as planned and covering the area of interest. This can reduce unnecessary radiation dose to the patient while increasing CT scanner throughput and productivity.

ASPIRE CI: SureStart Contrast Monitoring
SureStart provides the ability to monitor contrast media at a selected target and to automatically delay the start of a Helical scan until a pre-set concentration threshold is achieved.
Alternatively, the operator may manually begin the helical run after the contrast is seen to have arrived at the target. This capability allows the operator to optimize vessel and organ opacification, and potentially to reduce the volume of contrast material used without compromising image quality.
During Continuous Imaging, SureStart updates the image display at a rate of 8 frames per second.

Patient Management
Individual patient information can be entered at the time of examination, or in advance into an on-line patient appointment file to make actual patient scanning proceed as quickly as possible.

Scanogram
The Aquilion 16 performs a Scanogram, a digital projection radiograph, for planning the axial and helical scans in the shortest time possible. The Scanogram can be up to 139cm in continuous coverage which is useful for planning multiple helical exams and for trauma patients.

Scanograms can be acquired with thc xray tube at default positions of 0°, 90°, 180° or 270°, or at any arbitrary angle in 5° increments for optimum scanning flexibility. Scan planning is carried out with on-screen graphic overlays of the Scanogram which are used interactively to select and adjust scan slices, helical coverage area(s), voice command insertion time(s), gantry tilt, reference position, plan number, image number, and fields-of-view references

Image Management
Images can be stored on hard disk, magnetic optical disks, or transferred via an Ethernet connection to other storage devices or image networks. Image order can be sorted by a number of options, including image number, table position, gantry tilt, scan time, for the most useful presentation of stored information.

Image Display
• Display in multiple formats ranging from 1 to 16
• Overlay an inset scanogram for quick reference marking
• Add, subtract rotate or filter images
• Adjust window width and level non-linearly, accommodating up to six built-in curves and six user-defined curves.

Image Quality Enhancement
Automatic, 2-Pass, Beam-Hardening Correction (BHC): Compensates for the non-uniform, beam-hardening effect of bone for more accurate reconstruction. Reduction of streak artifacts in the posterior fossa and elimination of cupping artifact in the mid-brain.

Raster Artifact Suppression Protocol (RASP): Reduces artifacts caused by non-uniform attenuation such as in the shoulders and pelvis, and may be applied prospectively or retrospectively.
Automatic Patient Motion Correction (APMC): Reduces streak artifacts caused by movement of high-contrast interfaces such as air, contrast or metal during scanning. APMC is especially useful for scanning trauma, sedated, or uncooperative patients.
Reconstruction Algorithms: Grouped by anatomical application, more than 20 algorithms are provided for customized image reconstruction according to the diagnostic information needed or physician preference.

·      POWER CONIIONER / DISTIUBUTOR 125 KVA UNIVERSAL
The PCDU- CT is engineered to address the vast majority of common power problems found in the hospital environment, thus providing clean power and goad grounding for optimal reliability and performance of CT systems. This device provides most of the electrical site preparation requirements of Toshiba CT systems, including:

o    Power Conditioning
The PCDU contains a combination of a shielded, ultra-low Impedance Isolation transformer with matched L-R-C low-pass filters and surge suppressors. The quality of power to the Toshiba system is improved in many ways:
The isolation transformer re-references the power line to the local ground point (with connection to local building steel), isolating the system from upstream, ground-quality problems.
The transformer shield helps protect against ground impulses and noise (common mode disturbances).
The sine wave tracking filter protects against both high-frequency noise and fast-voltage impulses (normal mode disturbances), clamping spikes and filling-in notches.
The surge suppressors protect against slower voltage impulses that have frequency below the filter cutoff.

o    Voltage Conversion
Wiring costs are significantly reduced since the PCDU accepts a single, 480V delta input with code minimum ground, supplying 120/2O8Vwye to the generator and the various other parts of the system.

o    Distribution
The PCDU comes prepackaged with the distribution breakers needed for each system feed. Having all system breakers in one location also makes it easier for service personnel to remove power.

o    Control
The PCDU includes a circuit breaker on the input (primary) and a 24 VAC control signal for remote, emergency off control of the circuit breaker.

o    Impedance Control
The ultra-low impedance design of the isolation transformer helps ensure the power feed meets the low impedance requirement of today’s CT labs as spelled out In the Toshiba Optimal Power Specifications (TOPS) manuals.
