最近刚刚按照 PS3 分了类，构造了每种modality的class。
现在的问题是对于每种 modality 应该进行何种操作，我不清楚，比如说下面的属性，我都不知道是用来干吗的，请大家帮帮忙。
谢谢！
下面列出的是 CR 的特有属性（这些属性都是标准中规定的）
KVP
(Peak kilo voltage output of the x-ray generator used)
Plate ID
(The ID or serial number of the sensing plate upon which the image was acquired)
Distance Source to Detector
(Distance in mm from source to detector center)
Distance Source to Patient
(Distance in mm from source to isocenter(center of field of view))
Exposure Time
(Time of x-ray exposure in msec)
X-ray Tube Current
(X-ray Tube Current in mA.)
Exposure
(The exposure expressed in mAs, for example calculated from Exposure Time and X-ray Tube Current.)
Exposure in µAs
(The exposure expressed in µAs, for example calculated from Exposure Time and X-ray Tube Current.)
Imager Pixel Spacing
Generator Power
(Power in kW to the x-ray generator.)
Acquisition Device Processing Description
(Describes device-specific processing associated with the image (e.g. Organ Description))
Acquisition Device Processing Code
(Code representing the device-specific processing associated with the image (e.g. CR Organ Filtering code))
Cassette Orientation
(Orientation of cassette, used to properly position the image for display.
Enumerated Values: LANDSCAPE ,PORTRAIT)
Cassette Size
Exposures on Plate
(Total number of x-ray exposures that have been made on the plate identified in Plate ID (0018,1004))
Relative X-ray Exposure
(Relative x-ray exposure on the plate. Meaning of values is implementation
specific. May be used to adjust the dynamic range of the plate digitizer (scanner).)
Sensitivity
(Read out sensitivity.)
这些属性的意义和用法，书上或多或少也有写，但不是看的很明白。如果说哪位有操作过、或写过相关的东东，或者是相应的好的网站，都请赐教。
请问医师，如果你要进行 CR 影像的浏览和处理，这些属性是不是光显示出来就可以了,还是说需要通过这里的某些属性对影像做一些后处理，看起来才更方便。
临床经验少啊 |
