Imaging Combo Enhances Disease ID, Treatment

JUSTINE MURPHY, SENIOR EDITOR, justine.murphy@photonics.com

Early detection and diagnosis of cancer and other such ailments, including cardiovascular diseases, can make all the difference in treating them quickly and successfully. In some cases, it could actually mean life or death for a patient. Seeing into the body and visualizing samples can aid disease discovery and make subsequent treatment more effective.

Justine MurphyClinicians have historically had to rely on x-rays, MRIs, CT scans, PET scans, and other similar technologies for disease detection and possible treatment options. But times are changing. Fluorescence imaging and sensing, combined with ever-developing microscopy techniques, are emerging as effective tools for detecting and identifying disease, and showing promise for ultimately better treatment options.

In our cover story, Jasper Bosch, a development engineer at Lambert Instruments, examines the progress being made with fluorescence imaging and sensing techniques. They’re getting a boost from advancing microscopy methods, as well, by combining light sheet fluorescence microscopy with super-slow-motion imaging, for example. Processes such as this make possible the construction of a 3D representation of a sample. Researchers also can now study molecular interactions and physicochemical parameters, including oxygen concentration or pH, with enhanced resolution and reduced time intervals.
