gpu

GPU-accelerated computation functions for dose calculation.

matRad_getCtFromGPU(ct, precision)

matRad_getCtFromGPU transfers ct cube data from GPU to host.: Gathers ct.cubeHU and ct.cube cell arrays from GPU memory back to host memory. Optionally casts the data to the requested numeric precision after gathering.

call

ct = matRad_getCtFromGPU(ct) ct = matRad_getCtFromGPU(ct, precision)

Input:

ct matRad ct struct with GPU arrays in cubeHU and/or cube
precision (optional) – ‘single’ or ‘double’. If empty or omitted, no cast is performed.

Output:

ct matRad ct struct with host arrays in cubeHU and/or cube

matRad_moveCtToGPU(ct, precision)

matRad_moveCtToGPU transfers ct cube data to the GPU.: Moves ct.cubeHU and ct.cube cell arrays to GPU memory. Optionally casts the data to the requested numeric precision before uploading.

call

ct = matRad_moveCtToGPU(ct) ct = matRad_moveCtToGPU(ct, precision)

Input:

ct matRad ct struct with host arrays in cubeHU and/or cube
precision (optional) – ‘single’ or ‘double’. If empty or omitted, no cast is performed.

Output:

ct matRad ct struct with GPU arrays in cubeHU and/or cube

matRad_moveDijToGPU(dij, precision)

matRad_moveDijToGPU transfers dij dose influence matrix data to the GPU.: Moves the dose influence quantities (physicalDose, mAlphaDose, mSqrtBetaDose, mLETDose) to GPU memory. Optionally casts the data to the requested numeric precision before uploading.

call

dij = matRad_moveDijToGPU(dij) dij = matRad_moveDijToGPU(dij, precision)

Input:

dij matRad dij struct with host arrays in dose influence fields
precision (optional) – ‘single’ or ‘double’. If empty or omitted, no cast is performed.

Output:

dij matRad dij struct with GPU arrays in dose influence fields

matRad_getCstFromGPU(cst, indexType)

matRad_getCstFromGPU transfers cst dose influence data from GPU to host.: Gathers all cell arrays stored in column 4 of the cst (dose influence data) from GPU memory back to host memory. Optionally casts the data to the requested numeric precision after gathering.

call

cst = matRad_getCstFromGPU(cst) cst = matRad_getCstFromGPU(cst, precision)

Input:

cst matRad cst cell array with GPU arrays in column 4
indexType (optional) – ‘int32’ or ‘uint64’. If empty or omitted, it will be cast to Matlab’s standard double.

Output:

cst matRad cst cell array with host arrays in column 4
