Bardscan®II User’s Guide
Important Information Product Description The Bardscan®II Ultrasonic scanner is a battery operated, portable B-mode ultrasonic scanner, intended for the non-invasive measurement of urinary bladder volume. The scanner includes an 8.4” colour LCD screen to display cross sectional images of the bladder. A mechanical sector scanning transducer with a round crystal provides a symmetrical ultrasound beam, and gives high lateral and transverse resolution with high sensitivity and a low signal to noise ratio. The bladder volume is calculated automatically when the image is frozen, or it can be manually calculated by placing two or more points on the periphery of the bladder. The volume is then displayed on the screen. An inbuilt thermal printer can be used to print results.

Bardscan®II User’s Guide General scanning procedure Ensure that a liberal quantity of ultrasound gel is used in all examinations. The most accurate measurements will be obtained while the patient is resting quietly in a supine position. The blue button on the side of the probe toggles it from frozen to transverse scanning and back. It does not identify the orientation of the probe, instead that is indicated by the black dot on the probe, which corresponds to the dot on the screen.
Scanning Frequency For bladder scanning select the correct frequency for the patient to be examined: Patient
Bladder Depth
Frequency to be used
Adult
0-20cm
3.5 MHz
Child
0-12cm
5.0 MHz
Position the probe over the bladder, and gently press down and alter the angle of the probe to obtain the optimum image.

Figure 8 – Scanned Image
The Bardscan®II will automatically attempt to find the edge of the bladder, mark it, and calculate the volume from that, displaying it at the top right of the screen. A single transverse scan may be used to calculate the bladder volume, or for a more accurate bi-planar volume both a transverse scan and a sagittal scan may be used (see page 15).
Page 13 of 36
Bardscan®II User’s Guide Manual Bladder Volume Calculation If you wish to adjust the automatic volume then you can do so as follows: Place at least two bladder outline points on the periphery of the bladder image by tapping the screen in the appropriate locations. Volume & Delete buttons will appear once you have tapped the screen. The Delete button can be used to remove points you wish to alter, or they can be selected and dragged on-screen with the stylus.
Figure 9 – Manual Volume
Press the Volume button to re-calculate the volume. The volume will be displayed on the frozen image display in the top right corner of the image. If the bladder image is not clear enough for an accurate calculation an error message will be given instead. Please try again. If no bladder is visible then the bladder is nearly empty and the volume may be assumed to be <10ml. Bladders of less than 50 millilitres are not usually considered significant, but this may depend on the guidelines within your organisation. Check these before making a determination.
Page 14 of 36
Bardscan®II User’s Guide Transverse and Sagittal Scanning For a truly accurate bladder volume scan it is recommended that you perform both a Transverse scan and a Sagittal scan. Scan and freeze a transverse bladder image as indicated in the previous section. Place the bladder outline points and calculate the bladder volume as described in the previous section. Press Sagittal Scan and rotate the probe 90° from the previous transverse scan bladder image, so that the black orientation marker is pointed towards the head of the patient.
Figure 10 –Sagittal Scan
Adjust the location of the probe so that the largest possible cross section of the bladder is displayed. Place the outline points on the sagittal image. Press the Volume button to calculate the volume. The volume will be displayed on the frozen image display. This value will be calculated from the data from both transverse and the sagittal images. If you do not calculate a transverse volume before a sagittal one you will receive an error message. Repeat the process from the transverse scan.
