Filed:

Jul 1, 2022
Appl. No.:

17/856559
Inventors:

- Foster City CA, US
Zhiping Mu - Foster City CA, US
International Classification:

A61B 6/00
A61B 6/06
Abstract:

A medical imaging system includes a collimator having a plurality of collimator parts configured to filter radiation emitted from a target object; a detector base; and a detector having a plurality of detector tiles, configured to acquire an image of the target object by detecting radiation that has passed through the plurality of collimator parts, wherein at least one of the plurality of detector tiles is tilted with respect to the detector base.

Appl. No.:

17/826575
Inventors:

Zhiping Mu - Foster City CA, US
International Classification:

G06T 11/00
G06T 5/00
G06T 7/00
A61B 6/03
A61B 6/00
A61B 6/06
Abstract:

A method includes providing a target object and acquiring measured images of the target object. Each of the measured images is acquired by filtering radiation from the target object by a mask having multiple holes and detecting filtered radiation by a detector. The method further includes providing an estimated image of the target object and calculating an updating factor for each of the measured images. The calculating of the updating factor includes partitioning a mathematical representation of the mask into multiple first regions; for each of the first regions, deriving a separate forward projection from the estimated image of the target object and the respective first region; and comparing the respective measured image of the target object with the forward projections. The method further includes updating the estimated image of the target object based on the updating factors.

G06T 5/00
G06T 7/00
A61B 6/03
A61B 6/00
A61B 6/06
Abstract:

A method of imaging reconstruction includes providing a detector and a collimator, operating the detector to acquire a measured image of a target object from photons passing through the collimator, partitioning the collimator such that the collimator can be represented by a first matrix, providing an initial estimated image of the target object, and calculating an estimated image of the target object based on the measured image and the first matrix. The calculating of the estimated image includes an iteration using the initial estimated image as a starting point. The method also includes partitioning the collimator such that the collimator can be represented by a second matrix larger than the first matrix, and calculating a refined estimated image of the target object based on the measured image and the second matrix. The calculating of the refined estimated image includes an iteration using the estimated image as a starting point.
