Advantages of Laser Speckle Imaging

Large field of view (adjustable for many centimeters in length and width) allows for a very large area of blood vessel interrogation. This is particularly useful for studying the progress of large area PDT treatments.

Can be useful to evaluating the extent and efficiency of invasive and non-invasive melanoma treatments.

Can be easily integrated with SFDI to conduct multi-modal measurements with one machine.

Applications of Laser Speckle Imaging

Cerebral blood flow testing: Cerebral blood flow monitoring is widely used in the research of cerebrovascular diseases such as cerebral ischemia, cerebral hemorrhage, cerebral infarction, brain injury, and vascular dementia.

Skin burn examination: Accurate assessment of burn depth early in the burn injury is critical to help clinically select the right treatment to avoid unnecessary surgery or hypertrophic scarring. The microcirculatory flow imaging system is recognized as an effective tool for accurate assessment of burn depth, which can improve the accuracy of clinical assessment of burn depth.

Intestinal and gastric blood flow: The mesenteric circulation is one of the largest vascular beds in the body and is closely related to the systemic circulation. The regulatory mechanism of mesenteric circulation has an impact not only on the local organs, but also on the systemic circulation.

Animal anesthesia process.

Hand-foot blood flow obstruction process.

Flap transplantation In microsurgery, more reliable methods of postoperative monitoring are needed, particularly in tissue-threatening obstructions, supplying arteries and draining veins, using microcirculatory flow imaging to assess the likelihood of detecting local and total venous outflow occlusion and total arterial occlusion in porcine skin flap models.

FAQ

Q: What is the principle of laser speckle imaging?

A: LSCI is based on the principle that the backscattered light from a tissue that is illuminated with coherent laser light forms a random interference pattern at the detector, the so-called speckle pattern.

Q: What is the difference between laser speckle and laser Doppler?

A: Laser Doppler perfusion imaging (LDI) is an established technique for early assessment of burn depth to help determine a course of treatment. Laser speckle perfusion imaging (LSPI) is an alternative laser based, non-invasive perfusion monitoring technique that offers rapid and high resolution images of tissue.

Q: What wavelength is laser speckle contrast imaging?

A: The system was developed to obtain laser speckle contrast and multi-spectral images simultaneously over a spectral range from 770 to 821 nm. The repetition rate is 5 Hz, which corresponds to the sweep frequency of the wavelength-swept laser.

Q: What are the applications of laser speckle contrast imaging technology in dermatology?

A: LSI is effective for evaluating vascular anomalies, cutaneous neoplasms, inflammatory dermatoses, autoimmune conditions, and dermal and subcutaneous growths through the detection of perfusion differences between lesional and perilesional skin.

Q: What does laser speckle look like?

A: High Contrast: Laser speckle patterns exhibit a high degree of contrast, with dark and bright spots sharply defined against one another. The contrast is a result of the interference between the scattered waves, with constructive interference producing bright spots and destructive interference leading to dark spots.

Q: How do you reduce speckle artifacts?

A: A number of averaging techniques have been used to reduce speckle. These methods include temporal averaging, spatial compounding and frequency compounding. These methods all average multiple decorrelated frames.
