Rigid transformation estimation mine each voxel in the transformed image using the corresponding in- Rigid Transformation Estimation RTE is one of the simplest forms of tensity in the reference image.

GPU is commonly used in the medical image registration in the medical imaging. Medical image registration image registration process because of GPU hardware supports to the algorithm has a property of six degree of freedom in the transformation linear interpolation [33].

The similarity transformation is not included in the rigid boring pixel which is similar to the seed point based on some criteria. The transformation. Tamaki et al. Park et al. The proposed method performance 3. In the CUDA implementation, they refer information from Many segmentation methods are computationally expensive while neighboring voxels using eight threads due to limitation of available running on large amount of dataset produced by the medical modalities.

When the segmented-region size increased, the single and Segmentation of image data before or during the operation has to be fast quad-core CPU methods required considerably increasing computation and accurate in the clinical environment. Image segmentation in medical time, whereas the CUDA exhibited a constant computation time. The famous segmentation methods have used in the areas of medical images obtained from polarized light imaging PLI [41].

Due to thresholding, region growing, morphology and watershed. Thresholding analyzed. They choose region growing for segmentation and accelerated Thresholding is a process to segment each pixel or voxel using one or the algorithm by a factor of about 20 using CUDA. They achieved high more threshold values. Thresholding is a simplest technique to imple- accelerating gain while creating threads per block. The simplest binary threshold is given as: These oper- 0 Otherwise ations based on set theory with binary images introduced by Serra [43].

The fundamental morphological operations are dilation and erosion that where, support the expansion and shrinking properties of images respectively.

These operations use a small matrix mask called structuring element. These morphological operations fully S is output image, pixel based independent operations that support parallel processing x and y are coordinate positions.

GPU is capable to shown in Fig. Various works has been done on the implementation of create number of threads which is equal to number of pixels or voxels in the morphological operations using CUDA.

Olmedo et al. They have taken various sizes of images to their experi- done a comparison on thresholding technique with CUDA and OpenCV mental study. They concluded that the GPU implementation improved the performance when the image size is increased.

Koay et al. They achieved 70 times speed up with hori- zontal erosion operation and 20 time speed up with vertical erosion operation while compared with existing methods. Watershed The gray scale image can be viewed as a topographic surface and treated as three dimensional object in the watershed segmentation. Here the third dimension is an intensity value of the pixel [46].

In the gray Fig. Watershed algorithm is more useful for seg- imaging datasets given by the various modalities [49]. Creating 3D menting the objects that are touching one another.

GPU helps this medical diagnostic the noise with valley. Image visualization categorized into two using CUDA [47].

They used multi degree watershed segmentation on groups: Vitor et al. Surface rendering off-the-shelf GPUs [48]. These algorithms constructed with the hetero- Surface rendering constructs the polygonal surface from the given geneous implementation of both serial and parallel techniques and medical dataset and render the surfaces [50].

The surface rendered after the Medical image processing combined with visualization makes new shading and hidden surface removal. Standard computer graphics pro- way to diagnoses and to evaluate the effect of treatment given to the cess can be applied for object shading.

GPU accelerates the process of patient more accurate and reliable by using computers. In many medical geometric transformation and rendering processes. Discussion computer games.

These devices are now increasingly used to accelerate the numerical computations like texture mapping, rendering polygons We have presented a compendious survey of medical image analysis and coordinate transformation. In this table, four areas of medical imaging pipeline Cline for creating a 3D surface consisting of triangles from a volumetric on GPU are described. The algorithm uses a parameter, called the urations, materials and speedup gain of each method are discussed.

The dataset is divided into a grid such that a number of cubes are optimize the medical imaging algorithms and implementations on GPUs formed. The corner of each cube is represented by the data point in the to achieve additional gain. Smistad et al. The denoising algorithms GPU programming. OpenCL gives better performance than CUDA process each pixel independently and access the data from their small because the largest dataset makes memory exhaustion.

Every convolution mask with rank one is separable.

But this is greater if we are considering larger convolution help of 2D projection with the semi transparent volume. The major mask. Medical image denoising algorithms are required these separable application area of volume rendering is medical imaging. Ray Programmers need to carefully optimize their memory access patterns casting is not implemented to any geometric structure and solve the to achieve high GPU performance.

Shared memory latency is X lower limitations in the surface extraction. Ray casting solves a major limitation than the global memory latency. It needs a random search in three dimensional reduce the more registers and global memory access.

The implementation result shows the form of 2D to 4D. They realized CUDA 2. Therefore it is important that new dynamic heart to clinical ECG signals to calculate and compensate for libraries continue to be produced and that existing one is continuously latencies in the visualization pipeline using GPU [56]. They have improved. Modern CUDA can support deep learning for medical images [59]. Optimized CPU multithreading implementations are desirable application in medical imaging.
