Method, system and computer readable medium for an intelligent search workstation for computer assisted interpretation of medical images

A method, system and computer readable medium for an intelligent search display into which an automated computerized image analysis has been incorporated. Upon viewing an unknown mammographic case, the display shows both the computer classification output as well as images of lesions with known diagnoses (e.g., malignant vs. benign) and similar computer-extracted features. The similarity index used in the search can be chosen by the radiologist to be based on a single feature, multiple features, or on the computer estimate of the likelihood of malignancy. Specifically the system includes the calculation of features of images in a known database, calculation of features of an unknown case, calculation of a similarity index, display of the known cases along the probability distribution curves at which the unknown case exists. Techniques include novel developments and implementations of computer-extracted features for similarity calculation and novel methods for the display of the unknown case amongst known cases with and without the computer-determined diagnoses.

Multi-sensor breast tumor detection

X-ray mammography has been the standard for breast cancer screening for three decades, but offers poor statistical reliability; it also requires a radiologist for interpretation, employs ionizing radiation, and is expensive. The combination of multiple independent tests, performed effectively at the same time and co-registered, can produce substantially more reliable detection performance than that of the individual tests. The multi-sensor approach offers greatly improved reliability for detection of early breast tumors, with few false positives, and also can be designed to support machine decision, thus enabling screening by general practitioners and clinicians; it avoids ionizing radiation, and can ultimately be relatively inexpensive.

Method for detection and diagnosis of lung and pancreatic cancers from imaging scans

A method of detecting and diagnosing cancers characterized by the presence of at least one nodule / neoplasm from an imaging scan is presented. To detect nodules in an imaging scan, a 3D CNN using a single feed forward pass of a single network is used. After detection, risk stratification is performed using a supervised or an unsupervised deep learning method to assist in characterizing the detected nodule / neoplasm as benign or malignant. The supervised learning method relies on a 3D CNN used with transfer learning and a graph regularized sparse MTL to determine malignancy. The unsupervised learning method uses clustering to generate labels after which label proportions are used with a novel algorithm to classify malignancy. The method assists radiologists in improving detection rates of lung nodules to facilitate early detection and minimizing errors in diagnosis.

Method and system for detecting and identifying patients who did not obtain the relevant recommended diagnostic test or therapeutic intervention, based on processing information that is present within radiology reports or other electronic health records

Occasionally relevant findings and important recommendations made within medical or radiology reports fail to elicit the appropriate follow-up due to multiple factors. The clinician may miss the recommendation or lose track of it while addressing a more acute illness, the recommendation may have not been conveyed to the patient, or the patient may fail to schedule or show-up for the subsequent exam. Prior literature indicates that a significant percentage of scheduled appointments result in no-shows or cancellations by patients, and a small but significant percentage of indicated follow-up studies are thus not obtained. Such omissions occasionally result in adverse consequences suffered by the patients, and increase the risk of legal liabilities to the clinicians or radiologists. A method and system is presented that identifies patients who did not obtain such recommended diagnostic tests or therapeutic interventions, and which sorts and filters the detected patients according to relevance of the recommendation, optionally discarding recommendations of low relevance, and facilitates the management of the detected patients.
