NIRS is a portable, cost-effective, and high-resolution imaging method that is similar to electroencephalography, magnetic resonance imaging, and positron emission tomography. Its portable and inexpensive design makes it an ideal choice for a variety of clinical applications. Unlike invasive lasers, NIRS uses an incoherent light source and allows for considerable motion in the patient. It is an excellent choice for breast cancer screening and has several advantages over alternative methods.
In one embodiment, the digital Near Infrared Medical Imaging system includes a multichannel near-infrared laser radiating circuit and a foreign body positioning apparatus. The apparatus includes a signal acquiring board and a scan control plate for capturing images of physiological tissue. A microprocessor stores the corresponding software program. Among other features, the system uses a multichannel near-infrared laser to provide high-resolution images.
NIRS imaging is low-cost and handheld. The method is classically safe and noninvasive, which means it does not interfere with other imaging modalities. Moreover, NIR is used together with other imaging methods such as MRI. It allows doctors to see tumors in more detail, enabling better resection. A similar approach has been tested in several studies and has shown that a conventional endoscope can be retrofitted with a fluorescence filter.
Another form of Near Infrared Medical Imaging is called fluorescence imaging. This technology allows doctors to visualize various tissues of the body at the microscopic level. It is especially useful in the diagnosis of retinal diseases and is also used for the imaging of epithelial and skin tissues. This technology has an innovative feature called agile focus control. The system uses membrane mirrors to adjust the focus of the OCT instrument.
The technology uses light waves with wavelengths in the near-infrared range, or nm, to measure the blood oxygenation and hemoglobin levels in tissues. This technology provides a non-invasive method of imaging the body, and its specific absorption of natural chromophores enables a physician to access important functional information. There are many advantages of near infrared medical imaging over conventional radio-imaging methods.
The wavelength used for near Near Infrared Medical Imaging is mainly determined by the amount of tissue that can be imaged. The smallest detectable intensity corresponds to a few millimeters of soft tissue, such as breast tissue. The technique is also a good choice for breast imaging. However, the resolution and specificity of images are low. Further research is needed to improve the accuracy of near infrared imaging. The wavelength of near-infrared light, around 650-950 nm, is ideal for imaging tissue. Near-infrared light waves can be used to measure hemoglobin levels and oxygenation of tissues. Compared to conventional radio-imaging techniques, near-infrared diagnostic imaging is noninvasive. In addition, the specific absorption of natural chromophores allows doctors to obtain functional information.
A variety of clinical applications for Near Infrared Medical Imaging have been established in recent years. One example of this is breast cancer screening. Researchers have found that this technique has superior resolution and is less invasive than other medical imaging methods. In addition to improving breast cancer screening, it also helps detect Alzheimer's disease and schizophrenia. The technology is highly portable and cost-effective compared to other imaging methods. Furthermore, it allows considerable motion of the patient during the imaging process.
