Inspectra CXR is an AI-based software designed to analyze adult frontal chest X-rays for signs of eight abnormality conditions, including Tuberculosis. The software assists doctors in prioritizing and triaging chest X-ray images. In addition to offering top-tier accuracy, Inspectra CXR provides flexible installation solutions, full integration with PACS systems, or a standalone AI server, all meeting world-class security standards.
Currently, Inspectra CXR identifies features suggestive of the following eight abnormality conditions:
1. Tuberculosis
2. Pleural effusion
3. Lung opacity
4. Pulmonary edema
5. Mass
6. Nodule
7. Cardiomegaly
8. Atelectasis
The system delivers AI results as a secondary capture on DICOM for PACS integration or as JPEGs for the Inspectra application. Both formats display the lesion locations in a heatmap, a list of AI findings, and abnormality scores corresponding to each finding.
Certification
1. Thai FDA Notification Certificate (Approved)
2. HSA Singapore Authorization (Approved)
Development Stage
On the Market
Deployment
Online & Offline
Intended Age Group
Adult chest radiographs, starting from 15 years old.
Target Setting
Primary health centers
General hospitals (above primary level)
Teleradiology companies
Government/public sector, e.g., national TB programs
Private sector
Current Market
Thailand
Input
Can be used to read images from any make and model of chest X-ray machine
Chest X-ray image format: DICOM, JPG
Chest X-ray type: Posterior-anterior chest X-ray, Anterior-posterior chest X-ray
Output
Output includes:
Heatmap
Dichotomous output indicating whether TB is likely present or absent
Dichotomous output indicating whether each abnormality is likely present or absent
Probability score for TB
Probability score for each abnormality
Location of each abnormality
The default threshold probability score is set at the optimal value for each abnormality condition, with 44% for Tuberculosis. This threshold cannot be adjusted by users but can be customized upon request.
Results are given in a structured report that presents the probability of abnormal findings as percentages and consists of three subsections:
1. Overall Abnormality Score: The score for the case across eight possible findings.
2. Tuberculosis Abnormality Score: The probability of signs of Tuberculosis.
3. Abnormality Scores for Other Findings: The probabilities for the remaining seven findings.
Lung abnormalities included in the TB Score: Calcification, Cavity, Consolidation, Fibrosis, Interstitial markings, Opacity
Additional findings reported by the product: Atelectasis, Blunted costophrenic angle, Lung opacity (includes consolidation, fibrosis, and interstitial markings), Pulmonary edema, Cardiomegaly, Mass, Nodule, Pleural effusion

On-premises customers can sign up for maintenance services and software updates. Please contact us for details.
Price
Inspectra CXR offers a volume-based annual subscription plan, which includes license costs and all maintenance services. For installation, there is a one-time upfront fee that depends on the solution selected by the client. Please contact info@perceptra.tech for more information.
Product Development Method
The most recent version of Inspectra CXR was developed using supervised deep learning, specifically convolutional neural networks (CNNs).
Training
1.5 million CXR images from a global population.
Reference Standard
Inspectra CXR uses certified radiologist reports as the ground truth/reference standards. For TB cases, Inspectra CXR incorporates certified radiologist reports, sputum tests, culture tests, and CT scans as ground truth/reference standards.
