Advanced Imaging Technology

NewTom VGi CBCT technology works by capturing in a single 18-second scan a series of 360 images and storing them as information in a digital database on a computer hard drive. NewTom's software then reconstructs 3D images, including primary reconstruction images in multiple planes, from the captured data, providing the highest quality images possible for use in diagnosis and treatment planning.

The 150x150mm field of view, coupled with the very small 0.3mm or 0.15mm focal spot of the NewTom VGi means that the highest quality images can be acquired and reconstructed with great accuracy. The volume of image data captured is also kept to a minimum. This translates into very short image reconstruction times, generally averaging about 90 seconds, and economical disk drive usage, since after the scan and reconstruction are complete, the raw data is no longer necessary and is automatically deleted from the hard drive, saving valuable disk space.

The NewTom VGi utilizes a flat panel x-ray detector, meaning extremely crisp and sharp images. And while bone and tooth structure remain the most important components for diagnosis and treatment planning, the NewTom VGi also provides excellent soft tissue imaging.

NewTom Safe Beam Technology

The NewTom VGi employs Safe Beam technology, which means that it automatically adjusts the radiation dosage according to the patient's age and size. This technology utilizes intermittent bursts of radiation only milliseconds in duration during image acquisition, and not the constant radiation stream typical of many other CBCT imaging products, patients exposure to radiation is in most cases significantly less than that of competing systems. Children, for example, receive up to 40% less radiation than adults during a typical scan. NewTom's Safe Beam image acquisition is the proven safe technology available today, for both patients and the dental team.

Multiple Scan Modes

The NewTom VGi has five selectable fields of view.

• Large F.o.V = 150x150mm. Ideal for Orthodontics.
• Zoom F.o.V = 120x75mm. Perfect for implant and high res imaging.

Faster image reconstruction for the NewTom VGi time means less wasted time for patients and staff

Smaller Footprint, Easier Patient Access

Because the NewTom VGi is an upright scanning system with no fixed seating, it provides unparalleled patient accessibility. Even those confined to wheelchairs can be positioned very easily for scanning. And the system's seating flexibility means that adults and children can be readily accommodated. In addition, since it looks very much like a panoramic unit, the NewTom VGi provides an important level of comfort and familiarity for patients.

A Practical, Space-Saving Option

The NewTom VGi has a footprint of about 113 cm x152 cm, making it a practical option even for practices where office space is at a premium. The complete NewTom VGi system includes scanner, cabinet with electronic circuitry (conveniently locatable up to 2.5m from the scanner), computer workstation, and all required software. A complete training program is also included with purchase or lease. The NewTom VGi's image quality, patient safety features, and flexibility make it the best value CBCT system on the market today.

Mobile 3D Scanning. The NewTom Van.

The NewTom VGi is also available in a shortened version for use in mobile scanning vans. The system has been highly successful in both North America and Europe allowing rural and remote dentists access to 3D volumetric scanning.

"I have been using the NewTom for a number of years now. It is a wonderful diagnostic tool and support is excellent. I am now also using the images produced by the NewTom in combination with the NobelGuide™ software with great results." Dr. Paulo Malo

Simple Graphical User Interface (GUI) with Dolphin Software

The NewTom VGi Cone Beam systems are delivered standard with Dolphin 3D imaging software. All scans are initiated from within the Dolphin software and the image data set will appear automatically once the reconstruction has been completed. This software includes powerful yet intuitive tools for you to process multidimensional datasets. There are no complicated commands or scripting language to learn. Processing and analyzing three-dimensional data has never been easier.

Object Orientation

To maximize the consistency of measurements of a 3D volume, it is crucial to establish a default orientation. Dolphin 3D provides comprehensive tools for defining the mid-sagittal, axial and coronal planes. You can also adjust the object's default yaw, pitch and roll. These operations can be performed on the CT soft tissue surface, CT hard tissue surface or 3D photo surface.

Take advantage of the pre-set positions on an object that has been oriented: front, back, right, left, top, bottom, oblique and isometric views.

Multiple Planar Views and Layouts

Choose a layout that is best suited to your task:

• 3D volume (just the 3D volume view)
• Volume+3 planes (3D volume and 3 cross section planes on the side)
• 4-views (3D volume and the cross section planes in equal sized windows)
• Individual orthogonal projected slices: sagittal, coronal and axial planes

Instant Ceph/Pan

Create two-dimensional radiographic images from 3D volume dataset in the lateral, panoramic (OPG), frontal and SMV views. Reconstruct radiographs in:

1:1 projection (no distortion, no magnification)
Simple orthogonal/magnification projection (input % of magnification desired)

Complex traditional x-ray perspective projection (input detailed x-ray machine geometry; most accurately simulates traditional x-ray)

Image filters to help emphasize different structures of interest: including MIP (maximum intensity projection), Ray-sum (academic standard) and a collection of Dolphin proprietary filters.

Radiographic images can be saved in the Dolphin Imaging database for report generation and two-dimensional cephalometric tracing (Dolphin Ceph Tracing software required for 2D tracing).

Digitizing/Measuring

Dolphin 3D makes harvesting data from 3D volume simple, and is an excellent tool for research and data collection.

You can measure distances and angles in 3D; design your own analysis in 3D or in 2D (Dolphin Ceph Tracing software required for 2D analysis).

Landmarks can be used in a 3D analysis or translated into identified 2D lateral or frontal cephalometric analyses, such as Roth-Jarak, McNamara, etc. Further, the 2D points can include x-ray magnification to be compatible with existing norm values.

3D Nerve Marking

Patent-pending interactive tool to locate and isolate the nerve canal on a panoramic projection
Clearly draw the visible nerve canals with your choice of width, color
View/edit corresponding cross sections of nerve positions
View the marked nerve canal within 3D rendering of the skull volume

TMJ View

Choose an area of interest; set center point and axis direction, designed specifically for analyzing the temporomandibular joint
Choose desired slice thickness, width, number and direction (coronal, sagittal, or patent-pending circular)
View key cross-sections at the chosen axes

Cross Section View

Choose an area of interest; set center point and direction
Choose desired slice thickness, width, number, and direction (coronal, sagittal, or patent-pending circular)
View cross-sections at the chosen axes
Examine a nearly infinite number of groups of slices

3D Visualization

Dolphin gives you the power to freely visualize the volume in 3D. In addition to switching from hard tissue and soft tissue views, you can also activate the See-thru hard tissue renderings. Adjust the factor of translucency and intensity to reveal the structure you desire.

Clipping tools are also very useful for quickly visualizing hidden structures, or to simply eliminate portions of the contents that are not relevant.

Movie/Image Layout Scripts

You can create a script by collecting key frames (or, snap shots) of your 3D volume; by altering its position, zoom factor, translucency, segmentation and timing attributes.

Dolphin 3D can then create a smooth animated movie from your script. Spin, fly-by, exploit and see-through your volumetric object. Email movie files or add them to your Microsoft PowerPoint presentation. You control the movie speed, resolution, quality and file size with selectable video drivers (codec). Output to a variety of standard formats: AVI, Quick Time, MPEG, etc.

Automatically export the script keyframes as individual Dolphin images. Create a composite set of image layouts of your 3D volume for later viewing or for transfer to referrals.
