26. When low kilovoltage peak settings are used (65 to 70kVp) , a film with __ will result. a. High contrast b. Low contrast c. Many shades of gray d. Both a S c A B D 27. The quantity of the x-rays produced is controlled by: a. Voltage b. Kilovoltage c. Kilovoltage peak d. Milliamperage A B C D 28. __ is the overall darkness or blackness of a film. a. Contrast b. Quality c. Density A B

26. **A**. High contrast. Lower kVp settings result in a higher contrast image (more black and white, fewer shades of gray).<br /><br />27. **D**. Milliamperage. Milliamperage controls the quantity or number of x-rays produced. Kilovoltage peak (kVp) controls the quality or energy/penetrating power of the x-rays.<br /><br />28. **C**. Density. Density refers to the overall darkness or blackness of a film.<br />
