Question: What is the sentiment of the following document towards the entity Roya Qader ?  Qader  acknowledges that interpreting mammograms is usually the task of radiologists  but  his  goal is not to replace human physicians   he  says  but to help them — particularly in areas  often in low-income countries like Afghanistan  where trained physicians can be scarce.  Qader  believes  his  technology can aid doctors by quickly pinpointing diagnoses to allow for earlier and better care. Although there are mammogram machines in Afghanistan there are not enough skilled doctors to read the results   he  says. "They have the hardware — it's only getting cheaper — but not the manpower."

Positive
