New research conducted at the California Institute of Technology has resulted in a significant improvement in photoacoustic imaging technology, originally known as PATER, which has now been evolved into PACTER. The upgraded version reduces the complexity of the technology by requiring fewer sensors, allows for three-dimensional imaging, and eliminates the need for calibration before use, making it more efficient in medical imaging applications. The research and development of PACTER was conducted by Lihong Wang and Yide Zhang at the lab of the California Institute of Technology. PACTER, an improved photoacoustic imaging technology, simplifies procedures, enables 3D imaging, reduces operational complexity, and represents a significant advancement in medical imaging. This technique, known as PATER, was originally announced in 2020 and was developed by Lihong Wang and Yide Zhang, who have streamlined and improved the imaging technology. By using a device called an ergodic relay, the number of transducers needed has been reduced, making it a more practical and efficient tool for medical imaging. Also, PACTER can generate 3D images and does not require calibration before each use, unlike the previous version. These developments represent a significant progress in the field of photoacoustic imaging.
