Ultrasound imaging is a ubiquitous diagnostic technique, but does not fit the requirements of the telemedicine approach, because it relies on the real-time manipulation and image recognition skills of a trained expert, called sonographer. Sonographers are only available in hospitals and clinics, negating or at least delaying access to ultrasound scans in many locales-rural areas, developing countries-as well as in medical rescue operations. Telesonography would require an advanced imager that supports three-dimensional (3-D) acquisition; this would allow untrained operators to acquire broad scans and upload them remotely for diagnosis.

Article Synopsis
- Ultrasound imaging is an effective and cost-efficient diagnostic technique, but advanced 3-D systems face challenges due to the need for extensive calculations of acoustic propagation delays.
- The paper presents two designs for generating delay functions implemented on FPGA, assessing their hardware cost and performance for various ultrasound applications.
- The first design supports high-throughput 3-D imaging with significant memory access requirements, while the second offers an exact method that eliminates external memory needs, demonstrating the scalability for low-power and high-speed 2-D and 3-D imaging.
