    Stand unit that was improved so that users with long nails can observe their nailfold capillaries without damaging the long nails.

    Furthermore, improvements have been made so that users with long nails can observe their nailfold capillaries without damaging the long nails.

    The robustness of the stand is a very important factor during ultra-magnification observation.


    Extremely light and compact!

    The compact and portable camera unit of the GOKO Bscan-Z is only 150 g, which enables single-handed operation for long periods of time without stress.
    It also solves problems such as "capillaries at the observation site are pushed by the weight of the camera and blood flow stops."

    GOKO-VIP software for the measurement of the velocity of the capillaries

    Can be quantified with the velocity measurement software "GOKO-VIP" (Optional)

    With the software "GOKO-VIP (Velocity of Images and Pixels)", the velocity can be measured and saved as numerical values.

    • Data can be quantified. Numerical values can be used to express the velocity, which was conventionally intuitively judged as "fast" or "slow" by observing the capillaries.
    • Developed by GOKO in response to many requests for the best velocity measurement application for GOKO Bscan-Z.
    • The avi files shoot via the NTSC-USB2.0 converter are to be analyzed.

    We also accept requests for velocity analysis.

    We also accept image analysis requests. Contact us for details.

    We can also customize software.

    Utilizing the advantages of developing both the hardware and the software, we also accept requests for software customization.

    The GOKO-VIP is the software to measure the velocity, not the length or angles. The measurement of the length and angles can be easily performed with the free software attached to the recommended option, the NTSC-USB2.0 converter.

  • FAQ

    Q. It seems to be in focus immediately, is it auto focus?

    Manual focus. Because the depth position of the capillaries differs from one to another, it would be quite difficult for the auto-focus camera to focus well on the exact point you want to observe specially at ultra-high magnification. GOKO Bscan-Z enables quick and accurate focus on any visible skin capillaries. In addition, very clear capillary images can be obtained since the zooming is performed optically instead of digitally. These optical designs enable clear observation of leukocyte movement even at very high magnification.


    Q. Is all we can do with the GOKO Bscan-Z is to observe capillaries?

    No. By using the software "GOKO-VIP", you could quantify the velocity. By using the optional NTSC-USB 2.0 converter Set, you could save still images and uncompressed videos. The distance between two points can be measured using free measurement software attached to the converter set.


    Q. Can I observe only nailfolds?

    You could observe not only nailfolds, but also every body parts. By removing the camera from the stand, you could observe all parts of the whole-body surface such as the arm, the scalp, the legs, the tongue, the gums, and so on. In those cases, please use the optional Non-reflection cap set to obtain a clearer image without any reflection.


    Q. Is the camera heavy? I want to use the camera by hand.

    The camera weighs 140g, which is very light. The size of the camera is as small as 96mm, so there is no burden even if it is used for a long time.


    Q. Does the device require regular maintenance?

    No regular maintenance is required.


    Q. Do I need any consumables to observe capillaries?

    Oil and gel is essential for the observation. Contact us for details.


    Q. Are there any body parts where capillaries are easy to be observed? Are there any body parts where capillaries are hard to be observed?

    The body parts where the skin is relatively thin, such as fingertips, can be easily observed. On the other hand, the body part whose keratinous are thick, such as heels, might be difficult to be observed.


    Q. My fingers tremble easily. Isn't it difficult to observe the nailfold capillaries due to camera shake?

    The Anti-vibration cap and the stand unit are GOKO's anti-vibration design. They gently secure the fingers and greatly reduces the tremors of fingers without stopping the movement of capillaries. They are standard accessories.


    Q. What is a Non-reflection cap set?

    Non-reflection cap is an optional cap that enables capillary observation without any reflection in the capillary images. It was uniquely designed by GOKO. It is to be mounted in the tip of the camera body.


    Q. Do I need a special license to use the GOKO Bscan-Z?

    No. Since it is not a medical device, anyone can use it without qualifications.


    Q. Is it possible to see the capillaries on the scalp?

    Yes. You could observe any parts of the scalp: the frontal, parietal, and occipital parts. Clear and non-reflective movie can be obtained by using the optional Non-reflection cap set. If you observe a scalp with a lot of hair, use a smaller caliber cap (5φ) from the cap set.


    Q. Is it possible to observe the capillaries even in the oral cavity?

    Yes. By applying gel to the glass surface of the anti-reflective cap and covering it with a wrap film, capillaries of the anterior gingiva, mucous membrane, and tongue can be observed. We recommend using rubber bands to prevent wrinkling of the wrap.


    Q. Does the GOKO Bscan-Z focus at two magnification: lower and higher magnification?

    Yes. When using a stand unit, the low magnification is 145x and the high magnification is 590x. The magnification can be easily changed with the zoom ring.
    At lower magnification (145x), it is possible to grasp the shape and density of capillaries and it is easy to determine which point to be enlarged to 590x.
    At higher magnification(590x), it is possible to see how the white capsules move and to observe velocity easily and clearly.
    (Note) Magnification is converted on 20-inch monitors, so it is to be even larger on monitors larger than 20-inch.


    Q. What is the effect of oil?

    Oil or gel is essential for the observation of the capillaries just below the dermis of the skin. Contact us for further clarification.


    Q. What should I do when I found partial reflection in observing nailfold capillaries?

    When you use the camera with the stand unit, you can avoid partial reflections by bending the tip of your finger slightly downward. When you use the camera as a handheld camera, please use the optional Anti-reflection cap set.


    Q. Is it possible to observe skin texture?

    Yes. You can easily observe skin texture as well by using the attached focus cap without applying oil or gel. The GOKO Bscan-Z is also widely used for the research on the relation between skin texture and skin capillaries.


    Q. Is it possible to measure the size of capillaries?

    Yes. You could measure the size with the free software "IC Measure" included with the optional NTSC-USB2.0 converter set. It is possible to obtain accurate values by calibrating the chart first.


    Q. Which finger is commonly used to observe nailfold capillaries?

    Generally, the ring finger of the non-dominant hand is recommended to be observed. It is said that the nailfold skin of the ring finger of the non-dominant hand is the thinnest and thus the capillaries there are easy to be observed. However, choose another finger depending on individual conditions. In some protocols, it is recommended to observe eight fingers except the thumbs.


    Q. Is it possible to observe at another magnification that is different from the standard specification?

    Yes. We accept customization from one unit. Feel free to contact us if you have any special requests such as observing at higher magnification, changing the shape of the scope, or increasing numbers of pixels.
