We present here a new database that we are building to archive and distribute ultrasound images of an abdominal phantom acquired at different image acquisition parameters. With the aim of providing the research community a valuable US database that aids in the development of US image registration algorithms and 3D volume reconstruction algorithms, we have developed an ultrasound database of meta files that not only include image acquisition parameters, but also location of the US probe for each slice of the recorded US image.

We believe a publicly available database like this one will provide a valuable resource for the research community and it will be instrumental in developing a collaborative scientific community needed to advance the field.

<b>Data</b>

To generate the database, we used a TeleMed Ultrasound System and multi-modality abdominal phantom

<b>Telemed Ultrasound System</b>

Telemed Ultrasound systems based on LogicScan series ultrasound scanners are color Doppler scanners that are highly portable PC controlled ultrasound systems used to acquire and display real time high resolution ultrasound data in various modes, such as B-mode, M-mode, B+B mode among others. We use C3.5/60/128Z curvilinear probe which has frequency range of 2.0 – 5.0 MHz and 65 degree/mm field of view.

<b>Multi-modality abdominal phantom</b>

The multi-modality interventional 3D abdominal phantom Model 057 [CIRS, Norfolk, VA] provides a representation of an adult abdomen, designed to address various needs associated with liver biopsy (Figure 2). It simulates the abdomen from approximately the thorax vertebra T9/T10 to the lumbar vertebra L2/L3 using simplified anthropomorphic geometry.

A custom designed Visual Basic application, and PLUS (Public software Library for UltraSound) were used to build the database. The Visual Basic application communicates with the Telemed US scanner, and is capable of controlling B-mode controls of the scanner (Figure 3). The following acquisition parameters can be controlled: Depth, Gain, Frequency, Time Averaging, Dynamic Range, Power, and Time Gain Compensation (TGC) at 5 different depths. The acquisition parameters can be saved to a .txt file using the ‘Save B mode control values’ button. The GUI also provides functionality to save single US image or multiple images to file. PLUS, an open source toolkit for developing ultrasound guided image intervention was used for temporal and spatial calibration of the US and tracker systems, and to capture the metaIO images in a format that records both the US image and the transducer position and orientation data. Transducer tracking was performed using Micron Tracker, Claron Technology Inc [MicronTracker].
