To identify and monitor scoliosis, it is crucial to identify relevant parameters on the spine and conduct several measurements, such as the Cobb angle and the coronal balance. Manual analysis of these parameters is tedious, time-consuming and holds a high risk for inter- and intra-reader inconsistencies due to variations in clinical experience.
An integration of an automated AI based software could significantly maximize the reliability and accuracy. In addition, this should allow for a large amount of data to be handled in an automated way. AI can ultimately improve the effectiveness of pre- and postoperative evaluation and maintain a more patient-centered healthcare.
saves time and leads to higher inter-reader agreement
Patients with scoliosis are exposed to high levels of radiation due to the frequency of examinations. Improvements in standardization and consistency in measurements can potentially decrease the frequency of radiographic examinations and the associated radiation exposure.
Assists in detecting risk factors for treatment outcome
Pediatric scoliosis patients receive up to 42 x-ray examinations over the course of treatment
The mean Cobb angle is 5° higher in the afternoon compared to measurements taken in the morning
AI can reduce reading time of scoliosis x-rays by up to ~90%!
IB Lab SQUIRREL is a fully automated, radiological image processing software that aims to support physicians in the assessment of spinal morphology and scoliosis evaluation using frontal radiographs of the spine, particularly for the purpose of scoliosis assessment and disease progression. The algorithm is triggered automatically by a scoliosis study and returns relevant scoliosis parameters like the patient’s Cobb angle and the Coronal Balance. All findings are summarized in a visual output report, attached to the original x-ray image and saved automatically in the PACS system.
IB Lab SQUIRREL facilitates objective scoliosis assessment as well as monitoring disease progression.

IB Lab SQUIRREL is a radiological fully-automated image processing software device intended to aid medical professionals in the assessment and quantification of scoliosis by automating the measurement of Cobb’s angle and coronal balance on standing full-length spine AP/PA radiographs.
IB Lab SQUIRREL is intended to be used on patients of 10+ years with suspicion or diagnosis of Adolescent Idiopathic Scoliosis.
