Digital pathology is now rapidly developing around the world. As part of the wave, Hamamatsu's digital pathology slicer, NanoZoomer, has also traveled around the world as an important task in the process.
One of the NanoZoomer 2.0-HT in the Department of Pathology of the Affiliated Hospital of Akita University of Japan is one of them. This equipment has been used here for several years, and what kind of changes has it brought to the hospital? Dr. Nanjo Bo, who accompanied him on the eve of the day, told us about the “story†that NanoZoomer and the hospital had to say.

Q: I heard that when you are considering the introduction of digital pathology slice scanning equipment, you are expecting it to be connected to the Electronic Medical Record System (PIS). What do you think after you officially start using it?
Almost all previous expectations have been realized. The digital pathology image provided by NanoZoomer is as clear and detailed as that observed under the microscope, which fully meets our needs. Whether in the hospital or outside, as long as the digital section is called up in the electronic medical record system, not only the doctor, but also the patient himself can clearly see the pathological image and realize the sharing of pathological information. I think this is very important for grasping the disease and choosing the treatment method. It is beneficial, but it also strengthens the patient's trust in our diagnosis.
In addition, at the clinical multidisciplinary conference, using the mobile terminal, the image information of the imaging department can be viewed before surgery, and then the surgeon can provide the surgical observation and finally make a pathological diagnosis. This is all driven by the integration of electronic medical record systems and digital pathology slices, which is very helpful.
Q: How many computers can NanoZoomer connect to?
Digitally sliced ​​images can be seen in the electronic medical record terminals of more than 100 computers in our hospital. The image quality is still relatively good, and everyone's evaluation is also very high.
Q: Is the digital pathology image actually visible to the patient?
I have received a call from the clinician to confirm some problems with the reading. It seems that I should compare and explain the diagnosis book with the patient while looking at my diagnosis. For the patient, it is easier to understand than the language only, plus the description of the image. As long as there is a terminal, you can view digital pathological slice images anywhere.
Q: What are the benefits of using digital pathology to slice products?
Digital slicing makes sharing easier. With a simple computer and projector, the reading will be done. It can play a role in meetings, lectures, pathologists and cell diagnostics training, as well as external research sessions and societies. When reading a film, the same digital pathology image can be presented simultaneously in the view of everyone, so that everyone can view and discuss together. On the other hand, because all people can see it, there is some pressure on the pathologist (laughs). In terms of biopsy, diagnosis can be done almost by digital sectioning. Although it is not through digital pathology that all problems can be solved, but often hear the clinician say: "I really want digital slices."
Q: Have you encountered any difficulties in implementing the electronic medical record system connection?
(Hospital aspect) It is actually very difficult to suddenly propose to establish an interconnected electronic medical record system. A very important point in the process is to get the understanding and assistance of the doctors in the medical information department. This time, through the upgrade of the electronic medical record version, the interconnection was finally realized. Although the NanoZoomer digital pathology device has been introduced for several years, the previous clinical pathology conference only put digital slice images on the computer for reporting, and the clinical doctor will ask "when can you let us see?" Digital slice image?", this expectation is also a big motivation. Now, even without your own PC, or even with anything else, as long as you connect to the projector through the terminal of the electronic medical record in each department, you can clearly see the pathological section.
Q: How did you apply it?
When asked by the technician to perform a sweep, they are required to perform a semi-automatic operation in order to avoid scanning the useless portion of the slice. After the sweep is completed, the image is automatically saved into the electronic medical record system, which can then be viewed through the terminal. Also, it reads the QR code of the digital pathology slice together, and the information is automatically linked to the electronic medical record before the patient information.
Q: What expectations do you have for Hamamatsu's NanoZoomer in the future?
I hope that it is easier to cut out the desired part from the overall digital slice taken. Because each patient's electronic medical record file capacity is limited, if the image file becomes smaller, the file management server can be used more effectively.
Hamamatsu NanoZoomer digital pathology slice scanning device:
The Hamamatsu NanoZoomer series (NDP for short) is a high-speed, high-resolution digital slice scanner that enables networked data transmission. Traditional glass sections can be converted to high quality digital sections by rapid scanning.
Use the browser software NDP .view2 to view the digital slice image on the display. With the image browsing technology Navigation map (US patent RE42, 220E), you can view the slice as a microscope and watch it at any multiple. Whole slice or partial detail.
