Super-resolution imaging projectProject work: Monday, May 29, 13.00-17.00; Tuesday, May 30, 08.00-12.00 and 13.00-17.00; Wednesday, May 31, 13.00-17.00 in the group rooms Building 349, Ground floor Project presentation preparation is Thursday from 8:00-12:00, and the presentations are from 13:00-17:00. PurposeThe purpose of this project is to get familiar with nonlinear imaging. Data acquisition from a 3D printed micro-flow phantom with microbubbles, and making super-resolution images from the acquired data. The students will have to acquire the data for their own project, and then process the data using a simple super-resolution processing. Data and parametersData location in Dropbox: /CFU_summer_school_2023/assignments/SRI/ The variables stored in the env_bf.mat file has following descriptions: - env: envelope of beamformed data in uint8 format (0~255) - [Nz, Nx, Nt] = size(env); % Nz: number of pixels in z-dir, % Nx: number of pixels in x-dir, % Nt: number of frames - metadata - metadata.x_axis: x values of the beamforming grid (m) - [Nx, 1] vector - metadata.z_axis: z values of the beamforming grid (m) - [1, Nz] vector - metadata.frame_rate: frame rate of the imaging system (Hz) - metadata.f0: center frequency (MHz) - metadata.dynamic_range: actual dynamic range of env % If your system has a low memory try the batch compressed data % and load a fraction of frames Project descriptionPart I: Data generation:
Part II: Data processing:
Dissemination:Make a 10 minutes presentation of your project, which will be discussed on Thursday, June 1 from 13:00. There is 15 minutes available for each project group. |
