Cardiac interventional procedures are often performed under fluoroscopic guidance, exposing both the patient and operators to ionizing radiation. To reduce this risk of radiation exposure, we are exploring the use of photoacoustic imaging paired with

The successful integration of computer vision, robotic actuation, and photoacoustic imaging to find and follow targets of interest during surgical and interventional procedures requires accurate photoacoustic target detectability. This detectability

Channel signal-to-noise ratio (SNR) is a metric to assess photoacoustic image quality based on the raw photoacoustic channel data. Current methods for measuring channel SNR require access to raw data or delay data prior to summation (e.g., prior to D

Multiple image quality metrics are currently available to assess target detectability in photoacoustic images. Common metrics include contrast, contrast-to-noise ratio (CNR), and signal-to-noise ratio (SNR). The generalized contrast-to-noise ratio (g

Target detectability in photoacoustic imaging applications is traditionally analyzed using image quality metrics, such as signal-to-noise ratio, contrast, and contrast-to-noise ratio. These metrics are difficult to interpret in the context of target

Many cardiac interventional procedures (e.g., radiofrequency ablation) require fluoroscopy to navigate catheters in veins toward the heart. However, this image guidance method lacks depth information and increases the risks of radiation exposure for

Visual servoing is a promising technique for surgical tool tip tracking and automated visualization of photoacoustic targets during interventional procedures. However, visual servoing in photoacoustic imaging is challenged by the trade-off between la

The generalized contrast-to-noise ratio (gCNR) is a relatively new image quality metric designed to assess the probability of lesion detectability in ultrasound images. Although gCNR was initially demonstrated with ultrasound images, the metric is th
