DicomMetadata class

Represents the extracted medical metadata from a DICOM file header.

This struct contains critical parameters for clinical rendering, including spatial dimensions, windowing defaults, and patient identity.

Constructors

Properties

bitsAllocated → int
The number of bits allocated per pixel (typically 16).
final
bitsStored → int
The number of bits actually used to store the pixel data (typically 12 or 16).
final
hashCode → int
The hash code for this object.
no setteroverride
height → int
The number of pixel rows in the image.
final
highBit → int
The most significant bit of the pixel data (typically bits_stored - 1).
final
patientName → String
The name of the patient as recorded in the file header.
final
photometricInterpretation → String
The Photometric Interpretation (e.g., "MONOCHROME1", "MONOCHROME2"). Informs the renderer how to map pixel values to grayscale intensities.
final
pixelRepresentation → int
Specifies whether the pixel data is signed (1) or unsigned (0).
final
rescaleIntercept → double
The Rescale Intercept (Tag 0028,1052). Used for converting stored pixel values to Hounsfield Units (HU).
final
rescaleSlope → double
The Rescale Slope (Tag 0028,1053). Used for converting stored pixel values to Hounsfield Units (HU).
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
samplesPerPixel → int
The number of color components in this image (e.g., 1 for Grayscale).
final
width → int
The number of pixel columns in the image.
final
windowCenter → double
The default Window Center (Level) provided in the DICOM metadata. Maps to the average Hounsfield Unit of interest.
final
windowWidth → double
The default Window Width provided in the DICOM metadata. Determines the dynamic range around the center to be displayed.
final

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
