  * Yifeng and Prof Qin answered questions about MRI data preprocessing
  * Discussed the possibility of using multi-task learning for joint MRI image segmentation and hand functionality prediction.

==Meeting on Jan 6, 2020==
  * Discuss with Dr. Heng Liu on understanding MRI images for PVL diagnosis.
  * Dr.Heng Liu introduced how to distinguish the lesion of white matter.(by color and edge)

{{ medical_data:7.png?190 | The shcematic MRI image(the healthy region)}}
The red arrow and white arrow points to the lesion regions while the blue arrow points to the healthy region.
  * Yifeng and Dr.Heng Liu introduced how to know the specification of each image.(by pydicom)
{{ medical_data:5.png?300 | The information of the MRI image }}
  * Dr.Heng Liu set forth the aims of speculating on the possibility of cerebral palsy.


==Meeting on Jan 10, 2020==
  * Attendee: Yang Li, Jingyun Yang (R)
  * Jingyun Yang gave a presentation about the research of small white matter lesions{{ :medical_data:white_matter_lesion.pdf |}}

  * Meeting notes:{{:medical_data:meetingnotes01.pdf|}}

==Meeting on Oct 15,2020==
  *Attendee : Yang Li, Heng Liu, Jingyun Yang, Yicong Li
  *Data update:
  - more MRI images of patients with PVL
  - new classification of hand function in 5 classes
  *More symptoms of PVL: 
  - A->B->C:The volum of white matter decreases while lateral ventricle and sylvian cistern become larger 
{{ medical_data:sym2.png?400 | Another symptoms of PVL }}
  - A->B:The lateral wall of the lateral ventricle becomes irregular & B->C: Extensive cystic degeneration of the white matter around the lateral ventricle appears.
{{ medical_data:sym1.png?400 | Another symptoms of PVL }}
  *Standards for grading disease severity：
  - Hand function
  - Visible lesions in MRI images
  *Task Updata:
  - Lesions segmentation of MRI images
  - Classification of hand function
  - Counting of lesions
  - To be explored:changes of lateral ventricle
