Abstract
A medical imaging system is provided. Imaging detector columns are installed in a gantry to receive imaging information about a subject. Imaging detector columns can extend and retract radially as well as be rotated orbitally around the gantry. The system can automatically adjust setup configuration and an imaging operation based on subject shape estimation information.
Claims14
A detector system comprising:
- a nuclear medicine imaging detector;
- and
- at least one processor operably coupled to the nuclear medicine imaging detector, the at least one processor configured to:
- operate the nuclear medicine imaging detector to perform a preliminary imaging with the nuclear medicine imaging detector at least partially retracted,
- identify direct radiation acquired with the nuclear medicine imaging detector using a first energy window for the preliminary imaging,
- identify scattered radiation acquired with the nuclear medicine imaging detector using a second energy window for the preliminary imaging,
- determine a patient border using at least the scattered radiation for the preliminary imaging;
- and
- operate the nuclear medicine imaging detector to perform a subsequent imaging with the nuclear medicine imaging detector extended more closely to the patient than during the preliminary imaging, wherein the nuclear medicine imaging detector is positioned to perform the subsequent imaging based on the determined patient border.
6 more elements
A method comprising:
- performing a preliminary imaging with a nuclear medicine imaging detector with the nuclear medicine imaging detector at least partially retracted;
- acquiring radiation including both direct radiation and scattered radiation from an object with the nuclear medicine imaging detector for the preliminary imaging;
- identifying the direct radiation acquired with the nuclear medicine imaging detector using a first energy window for the preliminary imaging,
- identifying the scattered radiation acquired with the nuclear medicine imaging detector using a second energy window for the preliminary imaging,
- determining a patient border using at least the scattered radiation for the preliminary imaging;
- and
- operating the nuclear medicine imaging detector to perform a subsequent imaging with the nuclear medicine imaging detector extended more closely to the patient than during the preliminary imaging, wherein the nuclear medicine imaging detector is positioned to perform the subsequent imaging based on the determined patient border.

A non-transitory computer readable storage medium having stored thereon a computer program comprising instructions, which, when executed by a computer, cause the computer to:
- perform a preliminary imaging with a nuclear medicine imaging detector with the nuclear medicine imaging detector at least partially retracted,
- acquire radiation including both direct radiation and scattered radiation from an object with the nuclear medicine imaging detector for the preliminary imaging,
- identify the direct radiation acquired with the nuclear medicine imaging detector using a first energy window for the preliminary imaging,
- identify the scattered radiation acquired with the nuclear medicine imaging detector using a second energy window for the preliminary imaging,
- determine a patient border using at least the scattered radiation for the preliminary imaging;
- and
- operate the nuclear medicine imaging detector to perform a subsequent imaging with the nuclear medicine imaging detector extended more closely to the patient than during the preliminary imaging, wherein the nuclear medicine imaging detector is positioned to perform the subsequent imaging based on the determined patient border.
