ATL Ultrasound last month received a patent for its tissue harmonic imaging technology from the U.S. Patent Office. The Bothell, WA, companys technology reduces artifacts in ultrasound imaging that are caused by the interaction of low-frequency sound waves with certain tissue types.
The technology is based on proprietary signal processing technologies ATL uses in its HDI 3000 and HDI 5000 systems, according to CTO and senior vice president of product generation Jacques Soquet. Tissue harmonic imaging measures nonlinear high-frequency signals created when tissue interacts with ultrasound energy.
The technology is particularly suited for cardiology applications, in which up to 40% of patients are difficult to image with ultrasound due to physical characteristics such as obesity, pulmonary disease, or prior chest surgery, all factors that can create artifacts. ATL introduced tissue harmonic imaging technology in its HDI 3000 system in 1997 at the American College of Cardiology meeting and at the RSNA (SCAN 11/26/97).
Mammography Study Compares False Positives Between AI and Radiologists in DBT Screening
May 8th 2025For DBT breast cancer screening, 47 percent of radiologist-only flagged false positives involved mass presentations whereas 40 percent of AI-only flagged false positive cases involved benign calcifications, according to research presented at the recent American Roentgen Ray Society (ARRS) conference.
Study Shows No Impact of Hormone Therapy on PET/CT with 18F-Piflufolastat in PCa Imaging
May 7th 2025For patients with recurrent or metastatic prostate cancer, new research findings showed no significant difference in the sensitivity of 18F-piflufolastat PET/CT between patients on concurrent hormone therapy and those without hormone therapy.
