# dicom2jpg
Converts DICOM to `JPG/PNG/BMP/TIFF` and `numpy.ndarray`
# Installation
```
pip install dicom2jpg
```
# Introdunction
```
import dicom2jpg
dicom_img_01 = "/Users/user/Desktop/img01.dcm"
dicom_dir = "/Users/user/Desktop/Patient_01"
export_location = "/Users/user/Desktop/BMP_files"
# convert single DICOM file to jpg format
dicom2jpg.dicom2jpg(dicom_img_01)
# convert all DICOM files in dicom_dir folder to png format
dicom2jpg.dicom2png(dicom_dir)
# convert all DICOM files in dicom_dir folder to bmp, to a specified location
dicom2jpg.dicom2bmp(dicom_dir, target_root=export_location)
# convert single DICOM file to numpy.ndarray for further use
img_data = dicom2jpg.dicom2img(dicom_img_01)
# convert DICOM ByteIO to numpy.ndarray
img_data = dicom2jpg.io2img(dicomIO)
```
**dicom2jpg**
converts DICOM images to `JPG/PNG/BMP/TIFF` formats and to `numpy.ndarray`.
It piplines the lookup transformations by applying Modality LUT, VOI LUT, and Presentation LUT to the images,
which makes output files looks like what we see on standard DICOM viewers.
`dicom2jpg.dicom2jpg(origin, target_root=None, anonymous=False, multiprocessing=True)`
`dicom2jpg.dicom2png(origin, target_root=None, anonymous=False, multiprocessing=True)`
`dicom2jpg.dicom2bmp(origin, target_root=None, anonymous=False, multiprocessing=True)`
`dicom2jpg.dicom2tiff(origin, target_root=None, anonymous=False, multiprocessing=True)`
- origin can be a single DICOM file, a folder, or a list/tuple of file/folder
- target_root would be the root folder of the first file/folder if not specified
- exported files paths would be
> *target_root / Today / PatientID_Filetype / StudyDate_StudyTime_Modality_AccNum / Ser_Img.Filetype*
- anonymous files paths would be
> *target_root / Today / Patient_SerialNum / ModalitySerialNum_Modality / Ser_Img.Filetype*
`dicom2jpg.dicom2img(origin)`
`dicom2jpg.io2img(dicomIO)`
- converting dicom files or ByteIO to ndarray
- ndarray is in 8 bit; RGB format if it's a color image
