specific Embodiment approach

[0048] The specific implementation method is as follows: the memory data is re-sampled by a calibration algorithm to obtain the sampled data, and the sampled data is calculated through a power spectrum to obtain the original power data. The raw power data is generated by a continuous frame calculation algorithm to obtain continuous image data. Then, the obtained blood flow imaging algorithm is used to calculate the blood flow characteristics of the continuous image data, and then the enface algorithm is further used to obtain the blood flow distribution characteristics. Such as Figure 5 is a projection map of a 3D microvascular image.

[0049] Step S152, such as Image 6 As shown, this figure is an embodiment of a quantitative analysis module used in a device and system applied to the detection and positioning of vascular skin diseases. These include: skin blood flow contrast imaging71, image preprocessing72, vessel contour extraction73, vessel diameter size74, complexity ...

Abstract

The invention discloses a vascular dermatosis detecting and positioning device. A sample arm comprises a probe outer shell, a handle, a collimator, a scanning galvanometer, a galvanometer support anda lens and is characterized in that the lens is mounted on a threaded lens holder in threaded connection with the probe outer shell; a light-permeable sheet is mounted on a support which is arranged on one side, with the lens, of the probe outer shell, and a light path passes through the lens and the light-permeable sheet. A system comprises the sample arm, a wide-angle camera, a reference arm, a10:90 coupler, a circulator, a spectrograph, a computer, an infrared broadband light source and a red light source. In OCT-A vascular dermatosis clinical detection, uniformity of scanning positions before and after surgeries is realized, high stability in detection is realized, and debugging time in detection is shortened. In addition, stability and convenience in a vascular dermatosis detecting process are greatly improved.

Description

technical field [0001] The invention relates to the field of detection and localization of vascular skin diseases, in particular to a device, system and working method for detection and localization of vascular skin diseases. Background technique [0002] Vascular dermatosis is one of the common clinical diseases of skin cosmetology. Most importantly, vascular skin lesions can cause severe psychological trauma to patients. Common vascular skin diseases mainly include: port wine stain, strawberry hemangioma, cavernous hemangioma, mixed hemangioma and telangiectasia. Treatment methods include surgical resection, electrocautery, freezing, injection of sclerotherapy, etc., but these methods are difficult to control extensive and deep vascular lesions and have many side effects. The photodynamic therapy (PDT) invented by Professor Gu Ying from the Department of Laser Medicine of PLA General Hospital can effectively eliminate lesions without leaving scars. It has good curative e...
