Embodiment Construction

Actions and processes are to be represented as the manipulation and transformation of data as physical, electronic quantities within the registers and memory of a computer system as

other data similarly represented as computer system memory or registers or other such information storage

Store, transmit or display physical quantities within the device.

[0059] Note also that the software-implemented aspects of the example embodiments are typically encoded in some form of tangible (or recorded)

on the storage medium. Tangible storage media can be read only memory, random access memory, system memory, cache memory

storage, magnetic media (eg, floppy disks, hard drives, MRAM), optical media, flash memory, buffers, combinations of the foregoing, or for

Other magnetic devices (eg, floppy or hard drives) or other optical devices (eg, optical

disk read-only memory or "CD ROM"). Example embodiments are not limited in these respects by any given implementation.

Abstract

In an example embodiment, a method of visualization using a rendering technique in which voxels are sampled along rays traversing a volume is presented, the method comprising: obtaining voxel data, modifying a first portion of the voxel data, The first portion of voxel data is associated with a first segmentation mask. Modifying includes setting the first portion of the voxel data to at least one of a plurality of allowed voxel values. The method also includes applying a set of operators to the modified first portion of the voxel data and the remaining portion of the voxel data, and displaying the volume based on the applied set of operators.

Description

Method and system for segmentation volume rendering Background technique [0001] Volume rendering is a general method of synthesizing three-dimensional (3D) digital volume data into a two-dimensional (2D) image. due to not Different compromises are chosen in the same implementation, and the quality and appearance of the resulting image can be varied for different volume rendering engines. can vary greatly. [0002] For volume rendering, individual structures can be shaded from the volume data. This can be done by the user of the rendering system or by a pre- Define the structure to describe the mask. [0003] Examples of masks include stamping masks and display masks. The stamping mask has the following transfer function, which The numbers have an opacity of zero everywhere assigned to the mask, and have different transfer functions (i.e., not everywhere A mask of 0) may be referred to as a presentation mask. [0004] Stamping masks are used in volume rendering to av...
