Abstract
A method of Fourier ptychography microscopy (FPM) that includes obtaining images of a sample using an FPM system is provided. The method includes storing the images in a memory, uploading the images to a graphics processing unit (GPU), and performing FPM reconstruction using the GPU to generate a reconstructed image. The FPM reconstruction includes performing portions of the FPM reconstruction in parallel on the GPU to reduce FPM reconstruction time.
Claims40
A method of Fourier ptychography microscopy (FPM), the method comprising:
- obtaining images of a sample using an FPM system;
- storing the images in a memory;
- uploading the images to a graphics processing unit (GPU);
- and
- performing FPM reconstruction using the GPU, such that a reconstructed image is generated, wherein the FPM reconstruction includes performing portions of the FPM reconstruction in parallel on the GPU, such that FPM reconstruction time is reduced.
2 more elements
A Fourier ptychographic imaging system comprising:
- a plurality of light sources configured to emit light onto a sample location;
- an optical system configured to image at least a portion of a sample positioned at the sample location;
- an image capture device configured to capture images of the sample through the optical system under different light conditions provided by the plurality of light sources;
- a processor;
- a graphics processing unit (GPU) in communication with the processor;
- and
- a memory coupled to the processor, the memory including computer executable instructions stored therein that, when executed by the processor, cause the processor to:
- obtain the images of the sample positioned at the sample location;
- store the images in the memory;
- upload the images to the GPU;
- and
- initiate Fourier ptychography microscopy (FPM) reconstruction using the GPU, such that a reconstructed image is generated,
- wherein the FPM reconstruction includes performance of portions of the FPM reconstruction in parallel on the GPU, such that FPM reconstruction time is reduced.
