    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."


    Wasting time changing magnification and adjusting focus?
    With GOKO, the adjustment takes only 1 second!

    Having trouble changing magnification or adjust focus?
    Difficult to find the observation point?
    With GOKO, you can switch between "whole image" and "super magnification" in only one second.
    It contributes to the fixed point of observation because you can first look at the whole image and then super-enlarge it.

    you can switch between 'whole image' and 'super magnification' in only one second.

    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.

    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.


    Advanced image-analysis is available by the software "GOKO Measure Plus"

    The optional software "GOKO Measure Plus" greatly expands the applicability of clear images captured by the GOKO Bscan-Z.

    It provides advaned image processing and analysis in addition to various two-dimensional measurement functions, such as capillary image tiling (panorama composition), superposition display / alignment, and background subtraction setting.

  • 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?

    GOKO Bscan-Z is mainly designed to be projected on a dedicated 9.7" monitor for easy observation. However, still images and uncompressed movies can be saved by using the optional NTSC-USB2.0 converter set.
    Using the 2D measurement software included with the converter, you can measure the distance between two points and the length of a curve using multiline.We also have "GOKO-VIP" software that can quantify the flow velocity using moving images of capillaries.
    We also offer "GOKO Measure Plus", a high performance image processing software.


    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.
    Optional Autoclavable non-reflex cap is available for use in clean fields.


    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.
    With the optional Camera handgrip, you can get a very stable image when observing capillaries.


    Q. Does the device require regular maintenance?

    No periodic maintenance is required. The camera uses LEDs as its light source, and in principle, there is no need to replace the lighting.


    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. Frontal, parietal, and occipital areas can all be observed. Clear and non-reflective movie can be obtained by using the optional Non-reflex cap set and Camera handgrip. The non-reflex cap has a small diameter that is also suitable for observing the scalp between the hairs.


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

    Yes. Use the Autoclavable non-reflex cap. Apply transparent toothpaste to the glass surface of the non-reflection cap to observe capillaries in the anterior gingiva, mucosa, and tongue. If you use regular Non-reflex cap, not autoclavable one, use a food-grade plastic wrap film to cover the cap after applying transparent toothpaste to the glass to keep cleaness. We recommend the use of rubber bands to prevent wrinkles in the plastic 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?

    You can use the free software "IC Measure" which is included in the optional NTSC-USB2.0 Converter Set, or the optional measurement software "GOKO Measure Plus". Accurate values can be obtained by calibrating with 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.


    Q. What are the merits of the GOKO Bscan-Z?

    1. Amaingly clear images with GOKO's unique non-reflection observation.
    2. GOKO, with 70 years of experience in optics, is responsible for the entire process from development, manufacturing, customization, and sales.
    3. Various software: We offer three kinds of software: free software and two kinds of paid software. The free software offers 9 measurement functions, scale display, text display, and Excel transfer. Optional "GOKO-VIP" can measure the flow velocity. Another optional "GOKO Measure Plus" realizes various processes such as panorama connection and superimposition in addition to 23 kinds of measurement functions.
    4. Magnification: When using a 20-inch monitor, the magnification is 145 and 590x without changing the lenses.
    5. Standard accessory stand: Adjustable in both XYZ directions, with anti-shake function, and even suitable for people with long nails.
    6. Body weight: 140g (when used as a handheld, only the camera part is used)

    Q. Tell me about the facilities and applications where it is being used.

    In the medical field, our device is widely known by the terms "capillaroscopy" and "Nailfold Video Capillaroscopy (NVC)," and is used in a wide range of fields, including internal medicine, plastic surgery, orthopedics, dermatology, emergency centers, and rehabilitation departments at university medical schools, affiliated hospitals, and public and private hospitals, as well as pharmacy departments and pharmaceutical companies.
    In the field of health, it is widely used in acupuncture and moxibustion clinics, fitness clubs, health food manufacturers, health appliances, functional water, hydrogen, etc. to confirm the effects of treatments and equipment.
    In the beauty field, the system is used to visualize the effects of cosmetics manufacturers, esthetic salons, and beauty clinics.


    Q. What is the meaning of the term "microcirculation"?

    It refers to the blood circulation in microvasculature, i.e., micro-arteries, capillaries, micro-veins, and arteriovenous anastomoses. Although not all the microcirculation can be observed, the GOKO Bscan series enables us to estimate the body functions and health conditions by observing the microcirculation in every part of the skin surface.


    Q. I would like to observe skin blemishes on my face in addition to the nailfold area.

    Yes. Use the optional Non-reflex cap and Camera handgrip. Apply gel or oil to the glass surface for observation, and you can obtain clear, non-reflective video of blemishes and skin capillaries. Both skin spots, melanin and capillaries can be observed clearly.

    See: https://youtu.be/UVhmB-wBYKg and https://youtu.be/9YUYvgBwkCM

    The mechanism of skin blemishes (an example of senile pigmentation) is due to an imbalance in the production and discharge of melanin in the skin caused by a disturbance in the skin turnover, which is a cyclical function in which new cells produced in the lower part of the epidermis reach the stratum corneum at the top surface and are peeled off as plaque, resulting in an abnormal accumulation of melanin in the epidermis. This is due to the abnormal accumulation of melanin in the epidermis. It is said that where there are many capillaries, factors that stimulate the production of melanin are produced, which activates the spots.
