“…This is a landmark-based statistical shape model technique that applies anatomical knowledge to form a set of training data in order to obtain a segmentation of determined structures, such as the nasal cavities, decreasing the manual intervention time required for the operation. 45 Huang et al elaborated on an automatic segmentation in order to obtain nasal models from CT for the analysis of CFD, showing high segmentation accuracy and an average distance error of 0.3 mm. 40…”

“…Second, a statistical shape model (SSM) computes the mean shape and the shape variations of the maxillary sinuses and nasal cavities. SSMs are widely used in medical image processing, such as image segmentation, 16 image registration 2 and image reconstruction. 10 SSMs allows to quantify geometrical variations and features from various shapes and anatomical structures.…”

“…Till date the studies on SSMs of paranasal sinuses essentially focused on automatic image segmentation. 16,25 There is up to now, to the best of the author's knowledge, no study that uses an SSM to guide the design procedure for steerable flexible surgical instruments. Third, design-oriented metrics are selected based on the SSM.…”

“…Figure 1 exemplifies the close proximity of the paranasal sinuses to the nasal cavity and highlights the connectivity between the two regions. The majority of existing nasal segmentation methods have either included nearby airway components as part of the segmentation [12][13][14][15][16][17][18], or require some form of manual intervention in order to derive results [17][18][19][20][21][22]. In the work of Bui et al [12], a multi-step level-set segmentation procedure was utilised to automatically segment the nasal cavity and the surrounding paranasal sinuses from cone-beam computed tomography (CBCT).…”

“…This is evident among studies that focused on segmenting just the nasal cavity itself, such as in the works of Kimura et al [20] and Alsufyani et al [22] where thresholding was used to segment the upper airway, and large amounts of manual delineation was required in order to separate the nasal cavity from the rest of the airway regions. Keustermans et al [21] made use of an active shape model (ASM) to semi-automatically segment the nasal cavity. An ASM is a landmark based statistical shape model (SSM) segmentation method which makes use of anatomical knowledge derived from a set of training data to segment a particular organ or structure [23,24].…”
