IGS - Integral Geometry Science

IGS is a Deep Tech company dedicated to solving human challenges by making the invisible visible through innovative technology.

Invisible to Visible through advanced mathematics 
capable of seeing through objects.

IGS technology leverages the breakthrough solution to the 'inverse problem of wave scattering' by Dr. Kenjiro Kimura and Dr. Noriaki Kimura, historically deemed an unsolvable issue in applied mathematics. Derived from this is the scattering field theory. IGS focuses on the research, development, and commercialization of technologies that reveal an object’s internal structure and condition by observing and analyzing the electromagnetic waves scattered within and on its surface.

The world's first technology for non-destructive rebar fracture and corrosion inspection, preserving the integrity of the structure.

Infrastructure

Rebar Deterioration Inspection System

Maintenance and management of many concrete structures in Japan’s infrastructure is becoming a serious problem because of their deterioration. The “Rebar deterioration inspection system” developed by IGS measures the distribution of spatial electromagnetic fields on the structure’s surface, and it accurately diagnoses the state of corrosion by visualizing the inside of the structure.​

Technology

Proprietary Calculation Theory for Visualizing Rebar Rupture and Corrosion

The rebar deterioration inspection system developed by IGS employs a groundbreaking ultra-sensitive sensing device, the first of its kind globally, based on imaging theory and quantum mechanical principles. This advanced technology measures the distribution of the electromagnetic field emitted by the rebar within the concrete at surface points, enabling nondestructive diagnosis of rebar rupture and corrosion conditions.

Inspection Method

The rebar deterioration inspection system can be mounted onto a moving vehicle, allowing for efficient diagnosis of underground rebars while in transit

Notably, this system has been successfully tested and implemented nationwide, including in beams at actual sites.

Nondestructive Rechargeable Battery Inspection Systems

While the demand for lithium-ion storage batteries is on a rise because of their material properties, defects in such batteries can cause heat generation and ignition. The “Storage Battery Nondestructive Imaging Diagnostic System” developed by IGS can measure the electric current-density distribution inside storage batteries, thus enabling nondestructive failure analysis and quality control.​

The walk-through security system is designed for use in various locations such as schools, shopping malls, public transportation hubs, and event venues. Traditional methods make it challenging to conduct antiterrorism and anti-robbery searches in these areas. However, the IGS system enables real-time weapon detection and risk analysis without disrupting the flow of people.

The world's first technology for precise and painless cancer detection, effective even in dense breast tissue.

Mammography

Microwave Mammography

Conventional breast cancer diagnoses are extremely painful because of the pressure applied, and the cancer detection rate is also low.​

“Microwave mammography,” as developed by IGS, employs a new method to solve these conventional problems by inversely analyzing cancer using microwave waveforms.​

The world’s first technology for detecting ​
cancer painlessly and with ultra-high accuracy

World’s first technology for accurate and pain-free detection of cancer, even in high density breasts​

The problem with conventional breast cancer screening​

World’s first computational theory created by IGS to inversely analyze cancer via microwave waveforms​

The microwave mammography developed by IGS uses the strong reflection of microwaves off cancerous tissue in breasts. Breast cancer has a higher amount of water molecules compared with normal tissues, resulting in higher relative permittivity. Microwaves emitted to the breast reflect at the border of breast cancer, where the relative permittivity is high, so it becomes possible to detect breast cancer by measuring the reflection.​

Microwaves penetrate to the greatest depths in the breast and are often reflected by breast cancer. Conventional techniques have failed to determine where the microwaves hit the cancer cells and identify the true nature of the same. However, with Professor Kenjiro Kimura elucidating the previously unsolved “inverse problem of wave scattering” in applied mathematics, it has become possible to inversely analyze cancer using waveforms.​

The examination is painless and takes approximately 10 to 15 minutes​

Microwave mammography involves tracing a probe containing an antenna along the breast surface. This probe transmits and receives microwaves, scanning the entire breast area and outputting the results to a computer. 

Unlike traditional mammography, this method does not require compressing the breast, ensuring a comfortable experience. The straightforward procedure of tracing the breast surface guarantees consistent imaging results, regardless of the operator, making the process highly convenient.

Precise positional identification using 3D images

Microwave mammography leverages scattered microwave data to generate 3D images, accurately displaying the position and size of cancerous tissue within the breast. This technique produces images with exceptionally high contrast, significantly enhancing the detection rate of breast cancer.

IGS microwave mammography utilizes scattered microwave data to create 3D images, accurately pinpointing the location and size of cancerous tissue within the breast. The images produced have an exceptionally high contrast ratio, ensuring a high cancer detection rate. Additionally, this method does not require breast compression, making the examination painless and eliminating the need for radiation exposure. A clinical trial is currently underway at IGS to further evaluate the efficacy and safety of our microwave mammography technology.
