WESTMINSTER -- Flagship Biosciences announced the United States Patent and Trademark Office has issued the company a new patent, No. 10,839,512, entitled “Method of dot detection within images of tissue samples.”flagship-logo 

The patent, one of several recent patents issued to Flagship, discloses a method to identify CISH (chromogenic in situ hybridization) and FISH (fluorescence in situ hybridization) dots on a tissue slide, as well as very small stained particles such as bacteria.

The patented method improves over previous state-of-the-art machine learning approaches and classical image processing methods to produce better results, provide easier adjustment for different applications, and potentially reduce costs.

“We are pleased to announce this new patent for CISH and FISH dot detection,” said Trevor Johnson, Flagship’s CEO.

“Our internal experiments show that our new method can identify and separate dots, especially if they are very close together, better than any previous method.

“Flagship’s new dot detection method is also much less sensitive to chromatic aberrations. Combined with sensitivity and noise robustness, this method should produce fewer false detections and fewer missed dot pairs. The method can also reduce the need for more sophisticated optical equipment.

“We’re excited to share the benefits of the method with our clients.”

Flagship said only three parameters are needed to tune the method, whereas state-of-the-art classical dot detection methods have many more parameters to tune through trial and error, leading to higher variations of performance.

Flagship said its patent is written to cover the use of the new dot detection method exclusively in images of tissue sections. Flagship explicitly allows its use in other applications such as cell cultures, radiology, and even astronomy, all of which can benefit from a better dot detection algorithm.
