The DICOM-RT Structure Set is an IOD specific to radiotherapy applications. In DICOM, the CT files hold the image data that would be expected from each 2D slice of a CT scan and define the Hounsfield unit (HU) values at each image pixel. The RT Dose was introduced in 1996 with Supplement 11 together with RT Image, RT Structure Set and RT Plan as the first RT-specific DICOM objects. DVHA-MLCA is a stand-alone command-line script to batch analyze DICOM-RT Plans using the MLC Analyzer code from DVHA. CT images had a slice thickness of 2 mm with an in-plane resolution of 0. . Name Name. Modifying the dataset by adding, changing and deleting elements. Thank you. After the radiotherapy plan is exported from the planning system as a DICOM-RT file, it contains the ideal “planned” machine parameters at each control point, which are extracted using a Python script containing log analyzer module in Pylinac [10]. This tool can be used to simulate radiotherapy treatment delivery and may be useful for studies evaluating plan robustness and dosimetric uncertainties from treatment delivery. When the user selects a patient in the DICOM management module interface, the import mechanism allows name: name of the DICOM RT file or patient archive XML file; path: path to the DICOM RT file or patient archive XML file; leftTrim: the channel in the exit detector data that corresponds to the first channel in the channelCalibration array; channelCal: array containing the relative response of each detector channel in an open field given KEEP RT Dose.
