"Euclid" 3D Image Viewer

"Euclid" 3D Image Viewer: Enabling 3D Image Display of Information Inside the Skin As Measured by the Hadatomo™ Series

The Euclid can display 3D images by superimposing data on melanin in the skin, the vascular network, and the skin structure, as measured by a Hadatomo™ tool, and can also easily create tomographic images. In addition, image display conditions can be imported as a configuration file, enabling easy comparisons of measurement data. The user-friendly 3D image viewer is an ideal tool for dermatological research in the fields of beauty and healthcare.
Furthermore, the numerical analysis function added in R2.00 enables automatic extraction of features from images of skin structures such as melanin, the vascular network, and pores, outputting them as numerical information. This supports numerical analysis of the amount of change in a group of measured images, contributing to research on skin (click here for details of the (numerical analysis function).

Euclid R2.00 is available as a free software with the same functions as R1.00. The functions added in R2.00 may be used by purchasing a separate license.

3D Image Display

The Euclid 3D image viewer can display measurement data acquired by the Hadatomo™ series three-dimensionally. Images can be rotated and displayed from any angle. Users can also easily switch to a top or side view.

Superimpose 2+ Types of Image Data

Users can freely combine and display skin structure data related to melanin, the vascular network, and ultrasound imagery.

Create Tomographic Images of Regions of Interest

Images can be clipped horizontally or tomographically to isolate any region of interest on the XYZ axes of the superimposed images.

Diverse Image Display Options

In addition to black and white images, you can also select any color map and display color images. The Euclid viewer also has a coloring function which can assign colors according to depth and oxygen saturation.

Example of a color map

Compare Data Under the Same Display Conditions

Users can save settings, such as image quality information including color map settings and brightness, and 3D display conditions, to configuration files. Import these configuration files to easily display and compare multiple datasets under the same conditions.

Features can be automatically extracted from each image of skin structures including melanin, vascular network, and pores, which are output as numerical information. These numerical information from image data can then be applied to statistical analysis.

Numerical Output of Features in Images of Vascular Networks

This function automatically extracts blood vessels from blood vessel images displayed by Euclid and outputs the branching points, length, and number of blood vessels as numerical values.

The following histograms can be created from the output numerical data.

Numerical Output of Features from Ultrasound Image

This function automatically extracts the area, diameter, and perimeter length of skin structures including pores from ultrasound images displayed by Euclid, and outputs them as numerical values.

Numerical Output of Features from Melanin Image

This function outputs melanin distribution as numerical values from melanin images displayed by Euclid.

Example of Numerical Analysis of a Blood Vessel Image

These are the results of measuring the forearm. (A) is the measured image before massage and (B) is the measured image after massage, respectively.

(A1) 3D image of the forearm
(B1) 3D image of the forearm (after massage)

The same measurement site is selected from both images. In the example on the right, we have selected a location where the same blood vessels are visible at 6x6 mm.
The number of blood vessels after the massage in (B2) seems to be greater than before the massage in (A2), but quantitative analysis is difficult under these conditions.

(A2) Extracted 3D image of blood vessel at 6x6 mm
(B2) Extracted 3D image of blood vessel at 6x6 mm

The following are the results of feature extraction of vascular networks for the images displayed by Euclid. Euclid automatically extracts branch points in vascular networks and blood vessels leveraging its function that only vascular networks are displayed in images. Numerical information can be output from these automatically extracted results.

(A3) Results of automatic vascular network extraction
(B3) Results of automatic vascular network extraction

This graph shows the numerical results obtained from Euclid. It shows the number of vascular networks extracted from the image and the density of photoacoustic signals in the image, both of which resulted in greater values after massage. It may be thought that the massage may have stimulated blood circulation, resulting in an overall increase in the photoacoustic signal.

Statistical analysis of the experimental results will also be possible by conducting similar experiments with an increased number of N.
