Simple Graphical User Interface (GUI)

Dolphin 3D includes powerful yet intuitive tools for you to process multi-dimensional datasets. There are no complicated commands or scripting languages to learn. Processing and analyzing three-dimensional data has never been easier.

Easy Data Segmentation and Visualization

You prepare the 3D object by grouping intensity levels in pre-set ranges for soft tissue and hard tissue. After this simple procedure, you can easily review the object’s solid or translucent skeletal surface; solid, translucent, or photo of soft tissue surface; or both simultaneously. Views can be combined, such as translucent skeletal structures with translucent soft tissue 3D photo facial texture map.

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 adjust the factor of translucency and intensity to reveal the structure you desire. Color tools help to further clarify anatomy and their spacial relationships.

Clipping tools allow you to quickly visualize hidden structures, or simply eliminate portions of the contents that are not relevant.

To maximize the consistency of analysis 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.



After a scan has been oriented, take advantage of the pre-set views: 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

You can also adjust Window Level (traverse through 12-bit, 14-bit or 16-bit levels of intensity), zoom, pan, rotate, etc.

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 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).

Analyze the airway by drawing a border around your selected portion of the volumetric scan; the program will automatically fill in and display all the airway space within that border, then report back telling you the volume of airway space in cubic millimeters. It will also locate, display and measure, in square millimeters, the most constricted spot of that airway.

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

Digitized landmarks can be saved in Dolphin Imaging and exported to a Microsoft Excel spreadsheet or other numerical analysis programs.

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

Back to top

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

Back to top

Cross Section View

• Choose a path
• Choose desired slice thickness, width, number and direction (linear or patient-pending circular)
• View key cross sections along the chosen path
• Examine groups of slices

Dual Volume Superimposition

Superimpose volume scans from different time points to visually track and accurately measure treatment changes in bones and in airways.

2D Facial Photo Wrap

Easily create a texture map on the facial surface of any CBCT, CT or MRI scan. Simply import the 2D frontal photo, and Dolphin 3D guides you through a quick and simple step-by-step process to add the photo to the 3D volume. No additional devices or add-ons are needed to create this wonderful visual identity for any patient’s 3D volume.

Automatically create animated movies by collecting “key frames” from your 3D volume or slice views. By altering the volume’s position, zoom factor, translucency, segmentation, clipping and timing attributes, create a movie script which may be reused for volumes of other patients.

Dolphin 3D then creates a smooth animated movie from your script. Spin, fly-by and see-through your volumetric object. Distribute movie files, add them to your Microsoft PowerPoint presentation, or play them on your iPod or other portable media player. You control the movie’s speed, resolution, quality and file size with selectable video settings.

You can also export the script’s key frames as individual images. Create a composite set of image layouts of your 3D volume for later viewing or for transfer to referring clinicians.

Reports

Create diagnostic reports from your volumetric dataset. You build a workup report specific to a patient’s indication and the specialty of the referral. Build your own library of templates for implant sites, TMJ, impaction studies, tissue pathology, sinus and airway evaluation, and more; a library of existing templates is provided. The template is easily populated on the fly with desired images and cross sections from the volume. Reports can be exported to a document file or hardcopy printout.
