About This Project

We hypothesize that information obtained with a handheld skin scanner device can be analyzed to detect skin cancer with at least 90% accuracy and less that 5% false positives. To test this we will build a device that illuminates the skin with light wavelengths specifically attuned to various types of subdermal tissues. Light returning from the skin to photodetectors will provide information that will allow lesion detection by novel tomographic reconstruction and machine learning techniques.

What is the context of this research?

Melanoma is a dangerous form of the skin cancer responsible for thousands of deaths every year. Early detection of melanoma is often done through visual inspection of pigmented lesions over the skin. However, visual inspection alone has limited and variable accuracy that can result in a patient undergoing a series of biopsies. Ongoing research aims to improve diagnosis using instruments that probe below the skin surface and analysis techniques that can discern more than the human eye.

We believe that there are opportunities for improving the state of the art of skin cancer detection. Our team brings wide expertise in image reconstruction, tomography, and machine learning that we believe can make significant and novel contributions.

What is the significance of this project?

The World Health Organization (WHO) reports a rapid increase of skin cancer cases.

In cases where early detection of skin cancer melanoma is achieved, the cost of treatment, usually a simple excision of the affected skin, is low and a five year survival rate of 95% is reported. The treatment of advance cases of melanoma is much more expensive and the five year survival rate is only 13%. Early detection of skin cancer melanoma is therefore crucially important.

We predict that our economical and convenient device will provide a
reliable early warning and greatly reduce the rate of serious outcomes
of this disease. We believe that our device will provide the early
warning that leads to more numerous favorable outcomes.

What are the goals of the project?

We will build a handheld device consisting of arrays of LEDs that emit
light into the skin at wavelengths attuned to the optical properties of
various types of skin tissues. Complementary photodetectors will register light photons emerging from the skin. These light patterns will be the raw data for the tomography and machine learning algorithms.

To test the device on live data, a medical facility will be brought into the picture. For example, a similar project conducted a pilot study at a clinic involving the cooperation of the medical staff and patients. Standard statistical methods will be used to validate the device. A detection accuracy of more than 90% with less than 5% false positives are the success criteria.

Budget

We need to sub-contract the device construction as we do not have the resources to do this ourselves. Once we have a working device, we can continue to test its performance. We anticipate that most of the complexity will be in the algorithms that process the output of the device.

The device is actually fairly simple, consisting of a set of light sources of various wavelengths and intensities and complementary light detectors. These are all standard components that can be commercially purchased for less than $1000 US, judging from similar devices.

We expect that bulk of the expense will be labor costs for the device fabrication, which is difficult to estimate. We have identified possible fabrication sources.

It is also difficult to estimate costs associated with medical facilities in order to test the device. However, the literature would seem to indicate that this will not be a significant financial obstacle.

Endorsed by

I was introduced to Tom Portegys through a mutual friend due to his innovation in skin cancer detection. I have lost a loved one to skin cancer and can attest to the difficulty that exists in detecting it early on black skin. Much of this is due to the lack of training on how to visually recognize early-stage melanoma on black people. Being equipped with a device like this would revolutionize health outcomes for this demographic. I am excited to endorse to project!

Flag iconProject Timeline

There are two main milestones: (1) Obtain datasets of skin scans from third parties to analyze using algorithms that we invent or adapt. This will establish both the the feasibility of the device and the specifications for its construction. (2) Build the device, using it to obtain additional data and refine the algorithms.

Team Bio

Once we have working hardware, we are confident our team has the expertise in tomography and machine learning to make a significant contribution to the diagnosis of skin cancer.

Tom Portegys

I'm happy to be coordinating this project, which has been a long-time goal of Dick Gordon. I think the team has the skills to make a real difference in improving skin cancer diagnostics. I work in machine learning, artificial neural networks and data science. I'm a senior contributor to the OpenWorm project (openworm.org) on a variety of projects related to computational biology.

Vitaly Vlasov

I have an M.Sc. in Applied Mathematics, and work on image reconstruction and pattern recognition. I've developed a number of effective reconstruction algorithms for artifact preventive few-view computed tomography, which use state-of-the-art processing technologies such as compressed sensing and deep learning.

Richard Gorrdon

I woke up one morning in the early 1980s, realizing that I could look into my skin with a microscope to see the 3D structure of a beauty spot (nevus). I tried it on myself, and it worked. About one in 100,000 nevi turn into a cancer called melanoma. Thus the first 3D nevoscope was prototyped. Nowadays, with faster computers and advanced digital cameras that replace microscopes, my dream of detecting melanoma before it spreads (metastasizes) is possible. With my excellent collaborators, we hope to make home skin scanning a reality.

I was a professor at the University of Manitoba in Winnipeg, Canada from 1978-2011. I’m now “retired”, collaborating with mostly younger scientists around the world, volunteer as a scientist for the Gulf Specimen Marine Laboratory in Panacea, Florida, and hold an adjunct position in the Department of Obstetrics & Gynecology at Wayne State University. I wrote the first paper on diatom nanotechnology founding that field and started adaptive image processing. I’ve published on algal biofuels, computed tomography algorithms, AIDS prevention, neural tube defects, embryo physics, astrobiology and research and social ethics. I’m also Book Series Editor of: Diatoms: Biology & Applications and Astrobiology Perspectives on Life of the Universe (Wiley-Scrivener), and an Associate Editor of the science journal BioSystems.
