Researchers at Virginia Tech are developing a method of moving small targets, such as cells and medicine, within a body in a noninvasive manner. The project can likely revolutionize robotic surgery.
One significant leap in this trajectory has been the integration of robotics into surgical interventions, revolutionizing the way operations are conducted and recoveries are managed. and noninvasive acoustics spearheaded by Assistant Professor Zhenhua Tian of Virginia Tech, who also earned a 2024 National Science Foundation Faculty Early Career Development Program award, is ready to change how doctors do surgeries.
This approach harnesses the power of acoustic energy emitters to create intricate 3D acoustic vortex fields, similar to invisible tweezers, capable of traversing biological barriers such as bone and tissue.), he explained that the emitters utilize a customized lens to alter the phase profile of transmitted acoustic waves, generating a 3D acoustic vortex field.
“For a focused ultrasound beam with a frequency in a range of 0.5 to 1 MHz, it can transmit through skull and has been used on commercial focused ultrasound systems. As our acoustic vortex beam is different version of focused ultrasound beam and have a 1 MHz frequency, it holds the potential to transmit through a skull,” he added.
