What is Exposure Time? Benefits of Long and Short Exposure in Medical Imaging

Medical imaging has empowered healthcare professionals to visualize the internal structures of the human body and diagnose various conditions. Fluorescent imaging, a specialized subset, allows researchers to study cellular processes with precision. One key aspect that significantly influences the image quality is the exposure time. Controlling the exposure times/setting the right exposure time can yield valuable insights, whether in medical diagnostics or fluorescent microscopy.

In this blog, we’ll explore how long and short exposure times can benefit medical and fluorescent imaging. We will also delve into the dynamic capabilities offered by Sony Pregius IMX264 CMOS sensor-based camera.

What is Exposure Time?

The exposure time refers to the duration each pixel is exposed to light or photons. In medical imaging, exposure time directly impacts the quality of the captured images, Signal-to-Noise Ratio (SNR) and dynamic range.

Relationship between SNR and Exposure Time

Before exploring the advantages of long and short exposure times, it’s essential to grasp SNR and its connection to exposure time. The SNR, a vital metric in imaging, quantifies the quality of an image by comparing the signal strength to the level of effective noise. The formula for calculating the SNR is: Read More...
