AI-powered microscope in Cancer Diagnosis Breakthrough
December 25, 2020



  • DeepDOF, a new microscope, uses artificial intelligence to quickly and cheaply image all the cells in a large section of tissue with minimal preparation at high resolution (left), eliminating the expensive and time-consuming process of installing a thin tissue slice on a slide (right).

    For a typical microscope, there is a trade-off between spatial resolution and depth of field, which means that only objects at the same distance from the lens can focus clearly. Even a few millionths of a meter near or far from the objective of a microscope, the features will be blurred. As a result, lab microscope samples are usually thin and mounted between slides.

    At present, the section is used to examine the margins of the tumor, and it is not easy to prepare. The removed tissue is usually sent to a hospital laboratory, where experts either freeze it or prepare it with chemicals, then make extremely thin sections and attach them to slides. This process is time-consuming and requires specialized equipment and trained workers. Hospitals rarely can examine slides at the edge of tumors during surgery, and relevant health institutions in many parts of the world lack the necessary equipment and expertise.

    DeepDOF uses a deep learning neural network and an expert system, which can study a large number of data to make decisions similar to human. The researchers showed it 1200 images from a database of tissue slices. From this, DeepDOF learned how to choose the best phase mask to image a specific sample, and how to remove blur from the image captured from the sample to focus cells of different depths.

    Richards-Kortum, Rice’s Malcolm Gillis University Professor, professor of bioengineering and director of the Rice 360° Institute for Global Health said, “A clinical study is needed to find out whether DeepDOF can be used as proposed for margin assessment during surgery. We hope to begin clinical validation in the coming year.”

FAQ

  • Q1: Can COVID-19 nucleic acid test swab be replaced with cotton swabs?

  • A: You bought your own kit for testing the new crown. You dare not use his throat swab and want to use cotton swabs instead. In this case, it is not possible, because the thing he gives has a mesh on it that is easy to store and cotton swabs are not convenient. So you'd better be equipped, and you'd better go to the hospital and ask the doctor to test you.
  • Q1: What payment methods do you accept?

  • A: We accept payment by T/T in advance, Western Union, L/C. 
  • Q1: How long is your production delivery time?

  • A: For the delivery time, 7-10days for samples, 30days for mass production.
