The proposed concept developed within the DICOM's patient-based reference coordinate system allows to synchronize all image data of two different studies/examinations based on a single registration. The most suitable DICOM series for registration could be set as default per protocol. Necessary basics ...
This means that the dicom world (or patient) coordinate system isLPS: X is Right to Left (RL) Y is Anterior to Posterior (AP) Z is Inferior to Superior (IS) Dataset with Axial scans? If we want to look at theAxialaxis in world space, it means that we need to face towards theSup...
Coordinate transformations to the coordinate systems of commonly used Monte Carlo (MC) codes (BEAMnrc/DOSXYZnrc and VMC++) have been derived and published in the literature. However, these coordinate transformations disregard patient orientation during the computed tomography (CT) scan, and assume ...
DICOM differsfrom some, but not all, data formats in that it groups information intodata sets.That means that a file of a chest X-Ray image, for example, actually containsthe patient ID within the file, so that the image can never be separated fromthis information by mistake. This is si...
As you want to build volume from a series of images, it would be better to understand this patient-based coordinate system. It will help you to build the volume in correct order, even if the patient is scanned in different orientation. gofaladded question on May 20, 2021 MartinOrtiz comm...

The derivation of polar angle and azimuthal angle is similar to the existing studies by applying a series of rotations to a vector in DICOM patient c.s. The derivation of beam rotation col for DOSXYZnrc, however, is different. It is obtained by a direct combination of the actual collimator...
A DICOM dataset often contains multiple series, each of which belongs to a study. The dataset may also contain multiple studies, each belonging to a particular patient. Each DICOM file has metadata in the form of tags. Tags store data about the patient, the procedure, the device that capture...
