The TI Embedded Processor Software Toolkit for Medical Imaging (STK-MED) is a collection of several standard ultrasound algorithms optimized for TI’s C64x+™ architecture. The algorithms showcase how medical imaging functions can leverage the C64x+ architecture for efficient performance and power consumption. The goal of the STK-MED is to shorten customer development time of medical imaging systems by providing optimized implementations of commonly used processing blocks. The source code contained in the STK-MED can easily be extended or modified to develop customized and differentiated modules.
The STK-MED contains optimized C64x+ DSP software for processing blocks commonly found in a medical imaging system. The STK-MED contains a detailed algorithm description, API documentation, benchmarks and test bench for each software module.
The software and test benches can either be run on a CCS device simulator or on a target device. (The C6455 DSK for Medical Imaging is a recommended platform for developing with the STK-MED.)
The STK-MED includes the following modules:
- Optimized kernel implementations for B-Mode processing
- Optimized kernel implementations for Doppler Processing functions for 1D Color Flow, 2D Color Flow, Wall Filter and Power Estimator
- Optimized kernel implementations of RF demodulation and decimation
- Optimized kernel implementations of Delay And Sum (DAS) receive beamforming
- Optimized system implementation of Scan Conversion on C64x+ DSP cores of the DM6437, C6455, DM6446 and OMAP3530 SoC
- Optimized math utilities
- 3-D rendering
- Real-time image processing for Optical Coherence Tomography (OCT)
These modules are offered in source code. The table below summarizes the deliverable form of each software module.
