St. Louis-based radiation treatment planning software firm CMS Inc. has signed an agreement to acquire iKnowMed, which markets electronic medical records systems to oncology specialists.

CMS would continue to operate iKnowMed from facilities in Berkeley, Calif., under the direction of current iKnowMed CEO Donald Simborg, MD.

CMS says the combined technologies would allow access to patient information as a patient's treatment plan would include dates, body locations and dosages where radiation was administered, as well as results of radiation therapy and medical images.

Terms of the proposed transaction were not disclosed.
