Product catalog summary
Introduction
The document introduces a new imaging technology with an 80 μm voxel resolution, providing high-quality images with low x-ray radiation exposure. This technology aims to deliver detailed imaging while minimizing patient dose.
Imaging Modes
The system offers four imaging modes to meet various diagnostic needs:
  • High Resolution Mode: Provides the highest spatial resolution, ideal for observing delicate bone structures.
  • High Fidelity Mode: Offers high data density for clearer images, suitable for zoom reconstructions.
  • High Speed Mode: Reduces motion artifacts, beneficial for patients who have difficulty remaining still.
  • Standard Mode: Suitable for both limited and broad fields of view.
Field of View and Resolution Levels
The system provides nine field of view sizes, ranging from 170 mm to 40 mm in diameter, to minimize x-ray dosage. Five resolution levels are available, allowing selection of voxel sizes from 80 μm to 250 μm, depending on diagnostic needs.
Zoom Reconstruction
Zoom reconstruction enables detailed examination of critical areas using voxel sizes as small as 80 μm, enhancing image resolution.
Technical Specifications
The compact design requires minimal space, with recommended room dimensions provided. The system is DICOM compatible and includes viewing software for manipulating 3D-CT image data.
Principle of Operation
The system operates by rotating an arm 360° around the exposure region, emitting a cone-shaped x-ray beam. The resulting projections are converted into digital signals, processed, and reconstructed into 3D CT images.
Low X-ray Dosage
The x-ray dosage for a standard 18-second exposure is significantly lower than that of conventional CT scans, enhancing patient safety.
Isotropic Cubic Voxel
The isotropic cubic voxel ensures high-resolution images with minimal artifacts, maintaining image quality across all dimensions.
Flat Panel Detector (FPD)
The FPD enhances image quality and reduces x-ray dosage. It is unaffected by magnetic fields and provides high sensitivity and resolution.
Image Processing Software
The i-Dixel software offers extensive image processing capabilities, including volume rendering, real-time re-slice, and curved MPR. It supports DICOM standards and facilitates image sharing across clinic networks.
Conclusion
This advanced imaging technology provides high-quality, detailed 3D-CT images with reduced radiation exposure, making it a valuable tool for diagnostic imaging.
Overview
The document provides technical specifications and operational procedures for the 3D Accuitomo 170, a high-resolution imaging device developed by J. Morita Mfg. Corp. It includes details on software compatibility, positioning systems, imaging capabilities, and technical specifications.
Software Compatibility
The 3D Accuitomo 170 can be integrated into external clinic networks using i-Dixel Viewer Software, One Data Viewer, and One Volume Viewer, allowing 3D-CT images to be viewed on PCs even without the device present.
Positioning System
The Scout Positioning System is highlighted for its simplicity and accuracy, utilizing a triple beam system for precise targeting. It allows for easy targeting of the region of interest with two-direction scout imaging, minimizing x-ray dosage by accurately determining the minimal region of interest.
Imaging Capabilities
The device offers various imaging area options with different diameters and heights, allowing for detailed examination of specific regions such as the paranasal sinuses and temporal bone. High-resolution zoom reconstruction is available with voxel sizes as small as 80 μm for detailed observation.
Technical Specifications
The 3D Accuitomo 170 operates with a tube voltage range of 60-90 kV and a tube current of 1-10 mA. It supports multiple exposure modes, including Standard, Hi-Fi, Hi-Res, and Hi-Speed, with varying exposure times. The field of view options range from ø 170 x 120 mm to ø 40 x 40 mm, with voxel sizes from 80 μm to 250 μm.
Device Dimensions and Requirements
The main unit dimensions are 1,620 mm x 1,250 mm x 2,080 mm, and it weighs approximately 400 kg. The control box dimensions are 96 mm x 40 mm x 115 mm. The device requires a power supply of 100/110/120VAC or 220/230/240VAC with a maximum power consumption of 2.0 kVA.
Manufacturer Information
The device is developed and manufactured by J. Morita Mfg. Corp., located in Kyoto, Japan. Technical assistance is provided by NubiC, and the device is a result of collaborative development with Nihon University.
