Texas Instruments Inc. (TI) has released support for its medical imaging software toolkit (STK), a collection of powerful imaging algorithms targeted for TI's TMS320C66x DSPs. The upgraded toolkit offers image processing kernels for applications such as diagnostic ultrasound and optical coherence tomography (OCT) where high computational performance at low power levels and clear image quality are essential.

"With our free STK 3.0, easy-to-program KeyStone multicore architecture and powerful C66x DSP core, we are enabling developers to much more easily design medical imaging products with a significantly shortened development time," stated Ramesh Kumar, business manager, TI.

Leveraging the sophisticated processing capabilities of C66x DSP and KeyStone multicore architecture, the STK 3.0 enables both B-mode and color-flow processing for ultrasound. It also allows key kernels such as real-to-complex fast Fourier transform (FFT) and cubic spline interpolation for OCT. Software programmability in TI's C66x DSPs can allow for code reuse across systems, from portable to high-end applications and easy adaptability across many clinical applications.

The STK 3.0 has software modules that allow medical imaging developers to get to market faster while improving coding efficiency, yielding higher performance systems at lower cost and power, claimed TI. It also has well-defined APIs that simplify development by abstracting modules and enabling easy integration into existing systems, added the company.

The toolkit's optimal implementation references allow for function customization and provide coding illustrations of computational optimization methods for TI's DSPs, which can be modeled in custom processing functions. It likewise conducts full test benches with test vectors that provide assurance of module functionality while aiding in evaluation and development using TI's Code Composer Studio integrated development environment.
