California Doctor's Medical-Imaging Research Will Help Physicians Better Detect Cancer, Brain Disease


Akash Singh says the need for safe medical imaging is increasing as patients look to avoid costly hospital visits and instead receive treatment at smaller, less expensive health clinics.

The skyrocketing costs of health care are driving the need for more noninvasive, safe medical imaging as patients look to forego expensive hospital visits for less costly treatment at local health clinics. Dr. Akash Singh, a resident of Sacramento, Calif., said his recent contributions to the field of medical imaging will make it possible for any physician to detect cancer and brain diseases more quickly and efficiently in patients who may not know they have the deadly ailments.

Research being performed by scientists like Singh is giving hope to those who suffer from Parkinson's disease, Alzheimer's disease and other fatal illnesses that they will have access to affordable health care that could extend their lives for many years into the future.

“This critical imaging can now be applied in small medical clinics, which could save patients thousands of dollars as those doctors perform the life-saving procedures themselves, without the need for a trip to the hospital,” Singh said.

According to Singh, “the impetus for these intense research activities derives from a need for imaging methods that are safe, noninvasive and capable of monitoring body structure and chemistry in vivo and in real time.”

The fields of magnetic and optical imaging of biomedical tissue are attracting researchers from diverse disciplines, explained Singh, who is an expert in the field of medical optics imaging science.

Hamid R. Arabnia, a professor of computer science at the University of Georgia, agreed.

“The major advantage of a magnetic resonance and optical imaging method is its potential for simultaneous diagnosis of disease,” Arabnia said. “Dr. Singh has made significant contributions to magnetic resonance imaging and optical coherence tomography, which is a rapidly developing technique.”

According to Arabnia, who is editor in chief for The Journal of Supercomputing, Singh's most well known work was done in the field of high-resolution cellular imaging, which holds great potential for early cancer diagnosis.

Singh developed an instrument to investigate the development of tumors in the human body.

“My work will make it possible to investigate cancer development at the cellular level. This achievement will benefit medical research extensively, impacting fields such as cell biology, cancer research, early disease diagnosis and drug medicine science,” Singh said. “It will eventually improve the health of human beings.”

Singh has also researched the detection of brain structure using magnetic and optical imaging.

“In neurology and cancer studies, the precise detection of pathology is very important because it can be used to diagnose brain diseases such as epilepsy, seizures and Parkinson's disease,” Singh explained. “Compared to ultrasound, optical coherence tomography imaging can supply a much higher resolution.”

High-resolution imaging is especially important for detecting brain tumors, he added.

“I was one of the first to use a light source at 1.0 micrometer to do high-resolution brain imaging, not only accurately obtaining linear distances but also curvilinear surfaces, interfaces and enclosed areas. This wavelength is close to the zero dispersion wavelength of water,” Singh said. “Therefore, as a result of my work, it was possible to eliminate the influence of the depth-dependent dispersion from water.”

Arabnia said Singh's research is influential. Singh's findings have been published in the IEEE Journal of Computer Science and Engineering.

“Dr. Singh's research in this area will help the development of novel medical imaging techniques and instruments for brain disease diagnosis and treatment of Alzheimer's and Parkinson's disease,” Arabnia explained.
