A recent article by Lee Dubay in BioOptics World looked at how spectral imaging is being used by researchers as they create and measure the effectiveness of noninvasive optical techniques to enhance the diagnosis of patients, and in this case, premature babies, using different wavelengths of light.
The principal researcher, Emilie Krite Svanberg of Lund University in Lund, Sweden, is an anesthesiologist seeking to measure the amount of oxygen in a baby’s lungs via near-infrared laser light. Currently, doctors use x-rays to measure the amount of oxygen, putting these small patients at a higher risk of developing cancer due to the radiation they are exposed to during an x-ray. The babies lungs struggle to get the amount of oxygen needed because they are underdeveloped.
“The basic principle of the method,” according to the BioOptics World piece, “is to send light of a certain wavelength into the body, and then measure how much of the light can be retrieved. Based on this, it is possible to calculate the oxygen supply.”
The near-infrared light wavelength used with the technique is exactly 760.445 nm, so the utmost in precision is required. These precise measurements help doctors determine what course of action is best for the babies, such as inflating a collapsed lung. As it turns out, the near-infrared light scanning technology could assist with this procedure as well.
“Today, the method requires one person to hold a measuring instrument against the baby’s chest, while another sits by the computer, registering the results. Our goal is to simplify this technology,” Krite Svanberg is quoted as saying in BioOptics World. “We hope that the measurements will be possible to perform automatically, by using small transmitters attached to the baby’s chest. This would enable measuring the lung function continuously, in a way that is completely safe and that doesn’t bother the child.”
Gooch & Housego is proud to make its own contributions to helping the medical community and its patients through innovations in spectral imaging. Gooch & Housego is applying its acousto-optic tunable AOTF filter-based HSi-440C spectral imaging system to imaging traditionally stained clinical pathology samples to which additional transmission stains labeling multiple specific biomarkers have been added. Because of this, the HSi-440C has now been implemented in cervical cancer detection and shown to provide the pathologist with significant additional information to aid in more accurate interpretation.
