Evaluation: Interson ViewBladder 10 Bladder Scanner

February 20, 2019 | Evaluations & Guidance


  • The primary purpose of the ViewBladder 10 is to calculate an estimate of urinary bladder volume. There are no contraindications for use of the device.
  • Major device components and software features include: a) User interface
    • A tablet computer with proprietary ViewBladder 10 software is the user interface of the device and is used to display a B-mode ultrasound image, patient data, imaging parameters, and bladder volume estimation, and has a battery status icon. Bladder volume estimations can be obtained using the Bladder Volume Auto, Bladder Volume 2D (two-dimensional), or Bladder Volume 3D (three-dimensional) mode.
      • The Bladder Volume Auto mode can be configured by the vendor based on user preference; the bladder volume estimation can be displayed and updated in real time on the B-mode image as the user sweeps the ultrasound beam through the bladder, or the scanner can be configured so that the bladder volume estimation is only displayed after the user freezes the B-mode image.
      • The Bladder Volume 2D mode prompts the user to manually measure the height and width of the bladder by placing calipers on the acquired B-mode image; then the device calculates the volume estimation based on those measurements.
      • Bladder Volume 3D mode prompts the user to obtain the 2-D measurements, then the user must obtain a new B-mode image perpendicular to the initial image, and measure the third dimension of the bladder. The scanner then uses the three measurements to calculate a volume estimate.
    • The tablet is a 25.4 cm (10 in) Hewlett Packard Pavilion X2 using a Windows 8.1 Home operating system.
