|
| ## Dataset Creation |
|
|
| ### Curation Rationale |
|
|
| This dataset was created with the motivation of developing markerless tracking systems for spine surgery. |

|
|
| ### Source Data |
|
|
| The source of the data is lumbar spine surgeries taking place at Humanitas Research Hospital. |
| #### Data Collection and Processing |
|
|
| <!-- This section describes the data collection and processing process such as data selection criteria, filtering and normalization methods, tools and libraries used, etc. --> |

|
|
| #### Who are the source data producers? |
|
|
| The dataset was produced from the caseload of several neuro-surgeons working at Humanitas Research Hopsital (Rozzano). The cases are lumbar surgeries. |
| The .pcd files were captured by an Azure Kinect camera. |
|
|
| ### Annotations [optional] |
|
|
| Further annotations are contained within the CT_DATA folder of the accompanying code repository. |
| #### Annotation process |
| |
| The annotations were created in a multi-step process, first coarsely by the operating surgeon. |
| This was used to roughly align a preoperative CT/MRI mesh with a reference frame for a particular sequence. |
| We then use the SpineAlign process, described in the paper, to iteratively deform and transform the mesh to better align with |
| the reference frame. Then points in the sequence are labelled positive (1) if within 50 mm of the registered mesh, otherwise negative (0). |
| Following the reference frame alignment, this is repeated for other frames, using ICP to keep the deformed mesh aligned. |
| |
| |
| #### Who are the annotators? |
| |
| The annotators are surgeons of Humanitas Research hospital in Milan, alongside researchers at the Hamlyn Centre, of Imperial College London. |
| |
| #### Personal and Sensitive Information |
| |
| No personal identifying information is contained in this dataset |
