It starts with a mosquito bite and can end in severe sickness and even death. Malaria claims the lives of more than one million people worldwide each year.
Spotting the disease is the first step toward treating it, but the current way to detect malaria is costly, time consuming and not very accurate.
“The people [who] were examining samples for malaria were having such a hard time getting the right answer. They were only right about half the time,” said Brian Grimberg, a biologist at Case Western Reserve University in Cleveland, Ohio.
The pictures on the left above show a patient with a benign bone tumor called an osteoid osteoma. The images on the right show the patient after doctors treated the tumor with focused ultrasound, a therapy that delivers high frequency sound waves inside the body without surgery.
Advocates for the technology say it is proving to be a useful and cost-effective treatment for a number of afflictions, from various cancers to neurological diseases.
“Focused ultrasound is increasingly being considered a game-changing technology,” said Kim Butts Pauly, a Stanford University professor of radiology.
