IN-SITU DATA COLLECTION ARCHITECTURE FOR COMPUTER-AIDED DIAGNOSIS
First Claim
1. A method for collecting medical data, comprising the following acts:
- (a) capturing, at a client site, an image of a lesion of a medical subject at the client site (S220);
(b) deriving, from the captured image, at least one feature of the lesion (S350); and
(c) transmitting, by the client site to a server disposed externally to the client site, one or more features derived in act (b) and ground truth that the lesion is either malignant or benign (S360, S370).

Abstract
Automated diagnostic decision support (104) in the imaging of potentially malignant lesions is distributed and streamlined to protect patient confidentiality and to lower bandwidth and transaction costs. At a client hospital site (108a, 108b), a software agent (132) monitors a database and responsively accesses an image of a lesion and ground truth that the lesion is malignant/benign (S310-S330). After computing at least one feature of the lesion based on the image (S340, S350), the software agent transmits the feature(s) and ground truth externally from the hospital, to a central diagnostic decision support server (S360, S370). When a client hospital site needs automatic diagnostic support, the lesion feature(s) of the new patient are likewise extracted and transmitted to the external server in a query message (S440). The classifier located on the server will return a diagnosis (benign/malignant) and a confidence level (S450, S460).

8. A data collecting device (116) located at a client site and configured for:
-
receiving ground truth that a lesion of a medical subject is either malignant or benign (S260); pairing the received ground truth with at least one feature characteristic of the lesion computed from an image of the lesion (S350, S360); and transmitting the pair to a server disposed externally to the client site (S370). - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A server (104) comprising:
-
a receiver for receiving, from any of the plural client sites, a respective pair comprising (a) ground truth that a lesion is either malignant or benign; and
(b) at least one feature of a lesion derived from an image of the lesion (144); anda diagnostic support processor for incrementally training (S430), based on the received pair, said sites being located externally from each other and from the server (148). - View Dependent Claims (20, 21)

22. A computer software product for collecting medical data (132), said product being located at a client site and embedded within a medium (128) readable by a processor, said product comprising instructions executable to perform acts comprising:
-
monitoring a database at the client site (S310); responsive to said monitoring, accessing, from the database, an image of a lesion of a medical subject and ground truth that the lesion is either malignant or benign (S320, S330); and outputting, for transmission to a server disposed externally to the client site, the accessed ground truth and at least one feature of the lesion derived from the accessed image (S360, S370). - View Dependent Claims (23)
