58
+ 1. Description of sources and methods used for collection/generation of data:
59
+ Dataset statistics
60
+ Overall, the CT scan dimensions are covering [487 : 512] × [441 : 512] × [241 : 829] voxels, and the trans-axial voxel size ranges [0.68 : 0.76] × [0.68 : 0.75] mm2 with a reconstructed slice thickness of [0.5 : 1.25] mm.
61
+
62
+ Annotation procedures
63
+ The annotation process for generating the ground truth was performed in three steps. First, the largest components (i.e., trachea and the first branches) were extracted based on a region growing, or a grow-cut method. Due to leakage, the region growing method did not yield satisfactory results in all cases. Therefore, for certain cases, the grow-cut method in 3D Slicer was used instead. In the second step, BronchiNet was employed to segment the smaller peripheral airways. In the third and final step, the segmentations were refined manually. Bronchial fragments and missed segments were connected, before false positives and fragments that could not be connected based on visual inspection were removed. All manual corrections were performed using the default segment editor in 3D Slicer. The manual correction was performed by a trained engineer, supervised by a pulmonologist. Finally, all annotations were verified on a case-by-case basis by a pulmonologist. The final annotations from the AeroPath segmentation included on average 128 ± 56 branches per CT scan.

15
+ Using Creative Commons Public Licenses
16
+
17
+ Creative Commons public licenses provide a standard set of terms and
18
+ conditions that creators and other rights holders may use to share
19
+ original works of authorship and other material subject to copyright
20
+ and certain other rights specified in the public license below. The
21
+ following considerations are for informational purposes only, are not
22
+ exhaustive, and do not form part of our licenses.
23
+
24
+ Considerations for licensors: Our public licenses are
25
+ intended for use by those authorized to give the public
26
+ permission to use material in ways otherwise restricted by
27
+ copyright and certain other rights. Our licenses are
28
+ irrevocable. Licensors should read and understand the terms
29
+ and conditions of the license they choose before applying it.
30
+ Licensors should also secure all rights necessary before
31
+ applying our licenses so that the public can reuse the
32
+ material as expected. Licensors should clearly mark any
33
+ material not subject to the license. This includes other CC-
34
+ licensed material, or material used under an exception or
35
+ limitation to copyright. More considerations for licensors:
36
+ wiki.creativecommons.org/Considerations_for_licensors
37
+
38
+ Considerations for the public: By using one of our public
39
+ licenses, a licensor grants the public permission to use the
40
+ licensed material under specified terms and conditions. If
41
+ the licensor's permission is not necessary for any reason--for
42
+ example, because of any applicable exception or limitation to
43
+ copyright--then that use is not regulated by the license. Our
44
+ licenses grant only permissions under copyright and certain
45
+ other rights that a licensor has authority to grant. Use of
46
+ the licensed material may still be restricted for other
47
+ reasons, including because others have copyright or other
48
+ rights in the material. A licensor may make special requests,
49
+ such as asking that all changes be marked or described.
50
+ Although not required by our licenses, you are encouraged to
51
+ respect those requests where reasonable. More considerations
52
+ for the public:

160
+ authority to forbid You from making technical modifications
161
+ necessary to exercise the Licensed Rights, including
162
+ technical modifications necessary to circumvent Effective
163
+ Technological Measures. For purposes of this Public License,
164

166
+
167
+ 5. Downstream recipients.

172
+ Licensed Rights under the terms and conditions of this
173
+ Public License.
174
+
175
+ b. No downstream restrictions. You may not offer or impose
176
+ any additional or different terms or conditions on, or
177
+ apply any Effective Technological Measures to, the
178
+ Licensed Material if doing so restricts exercise of the
179
+ Licensed Rights by any recipient of the Licensed
180
+ Material.
181
+
182
+ 6. No endorsement. Nothing in this Public License constitutes or
183
+ may be construed as permission to assert or imply that You
184
+ are, or that Your use of the Licensed Material is, connected
185
+ with, or sponsored, endorsed, or granted official status by,
186
+ the Licensor or others designated to receive attribution as
187
+ provided in Section 3(a)(1)(A)(i).
188
+
189
+ b. Other rights.
190
+
191
+ 1. Moral rights, such as the right of integrity, are not
192
+ licensed under this Public License, nor are publicity,
193
+ privacy, and/or other similar personality rights; however, to
194
+ the extent possible, the Licensor waives and/or agrees not to
195
+ assert any such rights held by the Licensor to the limited
196
+ extent necessary to allow You to exercise the Licensed
197
+ Rights, but not otherwise.
198
+
199
+ 2. Patent and trademark rights are not licensed under this
200
+ Public License.
201
+
202
+ 3. To the extent possible, the Licensor waives any right to
203
+ collect royalties from You for the exercise of the Licensed
204
+ Rights, whether directly or through a collecting society
205
+ under any voluntary or waivable statutory or compulsory
206
+ licensing scheme. In all other cases the Licensor expressly
207
+ reserves any right to collect such royalties.
208
+
209
+
210
+ Section 3 -- License Conditions.
211
+
212
+ Your exercise of the Licensed Rights is expressly made subject to the
213
+ following conditions.
214

246
+ 2. You may satisfy the conditions in Section 3(a)(1) in any
247

251
+ information.
252
+
253
+ 3. If requested by the Licensor, You must remove any of the
254
+ information required by Section 3(a)(1)(A) to the extent
255
+ reasonably practicable.
256
+
257
+ 4. If You Share Adapted Material You produce, the Adapter's
258
+ License You apply must not prevent recipients of the Adapted
259
+ Material from complying with this Public License.
260
+
261
+
262
+ Section 4 -- Sui Generis Database Rights.
263
+
264
+ Where the Licensed Rights include Sui Generis Database Rights that
265
+ apply to Your use of the Licensed Material:
266
+
267
+ a. for the avoidance of doubt, Section 2(a)(1) grants You the right
268
+ to extract, reuse, reproduce, and Share all or a substantial
269
+ portion of the contents of the database;
270
+
271
+ b. if You include all or a substantial portion of the database
272
+ contents in a database in which You have Sui Generis Database
273
+ Rights, then the database in which You have Sui Generis Database
274
+ Rights (but not its individual contents) is Adapted Material; and
275
+
276
+ c. You must comply with the conditions in Section 3(a) if You Share
277
+ all or a substantial portion of the contents of the database.
278
+
279
+ For the avoidance of doubt, this Section 4 supplements and does not
280
+ replace Your obligations under this Public License where the Licensed
281
+ Rights include other Copyright and Similar Rights.
282
+
283
+
284
+ Section 5 -- Disclaimer of Warranties and Limitation of Liability.
285
+
286
+ a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
287
+ EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
288
+ AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
289
+ ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
290
+ IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
291
+ WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
292
+ PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
293
+ ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
294
+ KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
295
+ ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
296
+
297
+ b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
298
+ TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
299
+ NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
300
+ INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
301
+ COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
302
+ USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
303
+ ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
304
+ DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
305
+ IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
306
+
307
+ c. The disclaimer of warranties and limitation of liability provided
308
+ above shall be interpreted in a manner that, to the extent
309
+ possible, most closely approximates an absolute disclaimer and
310
+ waiver of all liability.
311
+
312
+
313
+ Section 6 -- Term and Termination.
314
+
315
+ a. This Public License applies for the term of the Copyright and
316
+ Similar Rights licensed here. However, if You fail to comply with
317
+ this Public License, then Your rights under this Public License
318
+ terminate automatically.
319
+
320
+ b. Where Your right to use the Licensed Material has terminated under
321
+ Section 6(a), it reinstates:
322
+
323

324
+ it is cured within 30 days of Your discovery of the
325
+ violation; or
326
+
327
+ 2. upon express reinstatement by the Licensor.
328
+
329
+ For the avoidance of doubt, this Section 6(b) does not affect any
330
+ right the Licensor may have to seek remedies for Your violations
331
+ of this Public License.
332
+
333
+ c. For the avoidance of doubt, the Licensor may also offer the
334
+ Licensed Material under separate terms or conditions or stop
335
+ distributing the Licensed Material at any time; however, doing so
336
+ will not terminate this Public License.
337
