Medical FAQ

Any retinograph that allows acquiring images complying with the characteristics defined in the chapter "Image mode characteristics" should be compatible with quantusGL®.

It is important that the retinograph allows image storage either in an external memory or that it is connected to an external image storage system.

No, quantusGL is designed to work only with images in PNG or JPEG format.

To extract the image you will need that the retinograph is connected to an internal network, that the retinograph has USB output, or that it has CD/DVD output.

Since each retinograph is different, here are some generic steps to follow to extract the file in JPG or PNG format:

  • 1. If the copy cannot be made directly by the internal network, you must insert the storage device (USB or CD/DVD).
  • 2. Then you must select the images you want to export and click on the button or tab, to copy or export the images.
  • 3. Make sure that the format in which the images are saved is JPEG or PNG. Sometimes you may need to specify the destination drive (network/usb/cd/dvd).
  • 4. Once the images have been successfully copied you must remove the storage device.

If you have any doubts about extracting the images, we recommend that you contact your retinograph's technical service, who will be able to help you with this task.

Generally retinographs should have this option. However, in some cases they have it disabled, so you should contact the technical service as they are the only ones who can activate it.

Once you have extracted the images you will have them stored in a folder in the internal network, in a USB device or in a CD or DVD. What you have to do is:

  • 1. Connect the USB or insert the CD/DVD in the computer you are going to use. Remember that you must have Internet access from that computer.
  • 2. Log in to your quantusGL user account from the computer.
  • 3. Click on the Upload Image tab and the UPLOAD window will appear.
  • 4. In this window you must click on the +Add files button, and you will be shown another browser window from which you must locate the folder where you saved the images (folder of the internal network, the location of the USB device or the CD).
  • 5. Once you have located the folder where the images are located, you can select all of them and click on the Open button. Enter the patient data and click on the Continue button. The images will be loaded into the application so that you can continue with the sending process.

Don't worry, there are other means through which you can extract the images, such as CD/DVD, or the internal network in case you are connected to the hospital network.

For the correct functioning of the system, the image must meet the following requirements:

  • 45 degree field of view centered on macula and papilla.
  • The image must show the entire fundus of the eye adjusted. The retina must not be cut off.
  • The formation of a black frame around the retina should be avoided.
  • Avoid bright points of light on the image
  • Avoid shadows on the image
  • Avoid markers or measurements on the image.
  • The image should not be treated with any filter or processing of any kind.
  • It is recommended not to use an image resolution lower than 1Mpx.
  • The system accepts all image sizes, but will resize them to 1200x1200 px. Therefore, it is recommended to adjust to that size as much as possible.
