  		Figure 3. Average mean glandular dose per film (main oblique (OB) and caudocranial (CC) only) as a function of compressed breast thickness. The error bars show 95% confidence limits; for some data points the errors are too small to be seen.

  		Figure 4. Average mean glandular dose (MGD) per film (main oblique (OB) only) as a function of compressed breast thickness for manual and automatic beam quality selection. The error bars show 95% confidence limits; for some data points the errors are too small to be seen.

  		Figure 5. Average mean glandular dose (MGD) per film (main oblique (OB) only) as a function of compressed breast thickness for different models of X-ray set. The Lorad Mark IV is shown for "old" and "new" automatic exposure control software versions. The error bars show 95% confidence limits; for some data points the errors are too small to be seen.

  		Figure 6. Histogram of the average mean glandular dose (MGD) for main oblique (OB) films for 50–60 mm thick breasts. (Including only those systems where the sample had at least 20 films.)

  		Figure 7. The average mean glandular dose (MGD) for main oblique (OB) films of 50–60 mm thick breasts plotted against the MGD to the standard breast for each unit (using 28 kV and a Mo/Mo target filter combination). Only those systems where the sample had at least 20 films are included. A linear correlation fitted to pass through the origin is shown.

  		Figure 8. The average mean glandular dose (MGD) for oblique (OB) films and 1.57 times the average MGD to the standard breast at 28 kV Mo/Mo for different film–screen combinations. (Errors represent 95% confidence limits.)
