Analysis of selected sperm samples by a computer‐assisted system with high frame rate: A prospective study [PDF]
Health Science Reports, 2023 Background and Aims Due to the rapid motility of the selected sperm, sperm parameters cannot be accurately determined by the manual method. So, the application of a computer‐assisted sperm analysis system with a high frame rate (HFR‐CASA, 85 Hz) in sperm

High-Frame-Rate Speckle-Tracking Echocardiography [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2018 Conventional echocardiography is the leading modality for noninvasive cardiac imaging. It has been recently illustrated that high-frame-rate echocardiography using diverging waves could improve cardiac assessment. The spatial resolution and contrast associated with this method are commonly improved by coherent compounding of steered beams.

The Theoretical Highest Frame Rate of Silicon Image Sensors
Sensors, 2017 The frame rate of the digital high-speed video camera was 2000 frames per second (fps) in 1989, and has been exponentially increasing. A simulation study showed that a silicon image sensor made with a 130 nm process technology can achieve about 1010 fps.
