Medical Imaging Demo Application Starter (MIDAS)

Texas Instruments' Medical Imaging Demo Application Starter (MIDAS) illustrates the system-level integration of key medical imaging algorithm modules on Texas Instruments (TI) Multicore DSPs and System-on-Chips. MIDAS currently focuses on the Ultrasound and Optical Coherence Tomography (OCT) application domains. Source code for the algorithm modules themselves is made available as part of the Embedded Processor Software Toolkit for Medical Imaging.  

The latest version of the Ultrasound version of MIDAS available today is MIDAS Ultrasound v4.0.
The latest version of the OCT version of MIDAS available today is MIDAS OCT v1.0.

The table below summarizes MIDAS Ultrasound versions that are available for download. If this is your first time using MIDAS, we recommend using the latest version that is available. Weblinks to the relevant documentation wiki and source code are provided in the last column of the table.

MIDAS Ultrasound Versions

Version	Platforms	Algorithms Implemented	Output Resolution	User Interface	Other notable differences	Dataset	Release Date	Web Links	UseThisOverOtherVersionsWhen
Ultrasound 1.0	OMAP3530	Scan Conversion (SCU)	640x480	Rudimentary w/ push buttons. Functionality limited to Start, Stop, Mode Selection	1.Acquisition and Display frame rates NOT decoupled.	Sector scan of Heart	Nov. 6, 2009	1.Documentation:Click_here 2.Source Code: Click here 3.SD Card: Click here	Not recommended unless, 1. Interested only in SCU on C64x+ 2. Do not plan to build from source
Ultrasound 2.0	OMAP3530	1. B-mode Processing Unit (BPU) 2. Doppler Processing Unit (DPU) 3. Scan Conversion Unit (SCU)	640x480	Qt touch screen based user interface. Advanced User Interface w/ ability to switch modes and other configuration parameters on the fly.	1.Acquisition and Display frame rates NOT decoupled. 2. Relies on DVSDK 3.0 (longer setup process than newer DVSDK 4.0)	1.Sector Scan of Heart 2.Linear Scan Carotid Artery	July 7, 2010	1.Documentation:Click here 2.Source Code: Click here 3.SD Card: Click here	1. Would like to play with algorithm parameters on the fly during run time via advanced user interface 2. Has both sector heart and linear carotid datasets. Future versions include only carotid dataset (though you could use other datasets with necessary modifications)
Ultrasound 3.0	1.C6472 Multicore DSP 2.OMAP3530 SoC	1. B-mode Processing Unit (BPU) 2. Doppler Processing Unit (DPU) 3. Scan Conversion Unit (SCU)	640x480	Qt touch screen based user interface. Advanced User Interface w/ ability to switch modes and other configuration parameters on the fly.	1. Acquisition and Display frame rates decoupled to mimic real ultrasound system use-case 2. Can work in following modes: a.C6472+OMAP mode b.OMAP only mode, if C6472 is not connected 3. OMAP software based on DVSDK 4.0 (faster setup than previous DVSDKs) 4. 6472 software based on CCSv4.2.1	Linear Scan Carotid Artery	June 9, 2011	1.Documentation: Click here 2.Source Code: Click here	1. Want to use older C64x+ based multicore DSP (C6472) 2. Would like to leverage a touchscreen-based user interface 3. Want to use MIDAS on OMAP3530 only (also v4.0) 4. Don't mind lower output resolution (can be increased with source code and system level changes)
Ultrasound 4.0	1.C6678 Multicore DSP 2.OMAP3530 SoC	1. B-mode Processing Unit (BPU) 2. Doppler Processing Unit (DPU) 3. Scan Conversion Unit (SCU)	1280x720		1. Can work in following modes: a.C6678+OMAP mode b. OMAP only mode, if C6678 not connected 2. Higher resolution output via DVI	Linear Scan Carotid Artery	Dec. 5, 2011	1. Documentation: Click here 2. Source Code: Click here 3. SD Card: Click here	1. To leverage industry's highest performing multicore DSP, based on TI's latest floating-and-fixed-point C66x keystone architecture 2. Higher output resolution desired (720p) 3. Want to use MIDAS on OMAP3530 only (also v3.0)
