brief introduction:

This product is based onFPGAUsing the high-speed parallel characteristics of programmable logic devices, as well as its rich internal multipliers andRAMThe resource has completed the collection of venous images and the hardening of convolutional neural network algorithms, ultimately adoptingTIofDLPCompleted the design of a handheld venous projector and solved medical difficulties.

Text Introduction:

Intravenous sampling or drug injection is an essential means of treatment for doctors and patients. But for young and weak babies, the veins are very thin and difficult to find; Obese adults with thick sebum hinder the localization of veins, which not only troubles doctors and nurses, but also easily causes secondary harm to patients.

To address such medical challenges, we are based onFPGADesigned a handheld venous projector:VN-DP001. This device usesCylcone IV FPGAAs the main control device, under the projection of near-infrared lightCMOSSensors capture images; Continuing to utilizeFPGAWith the high-speed parallel feature, we use a large window multi-scale convolutional neural network to calculate the light intensity data partially absorbed by hemoglobin. Finally, through a series of image enhancement algorithms, weTIofDLPRe project onto the arm and overlay onto the veins that are not easily visible to the naked eye. The overall flowchart is as follows:

Thanks to thisFPGAWe use dedicated multipliers and abundant wiring resources40Frequency doubling, achieving equivalence9280The reuse of multiple multipliers ultimately achieves the high performance and cost-effectiveness of this product.

This product solves medical problems and brings good news to patients. As of now, this product has been cumulatively released both domestically and internationally4In the year, it sold in both domestic and international medical markets and continued to be favored by hospitals and related institutions.

along withFPGAWith the continuous improvement of computing power and the increasing demand for medical services, in the foreseeable future, handheld vein projectors with high resolution, high brush speed, and even precise depth detection will be the direction of development for such products. We will also continue to work hard and embraceintel FPGAContinue to deepen our cultivation in the medical field, committed to solving more problems and realizing the value of technology.
