Method and device for determining heme concentration of specified area in medical image

The invention provides a method and a device for determining the heme concentration of a specified area in a medical image. The method comprises the following steps: acquiring an area selection operation of a user in a to-be-processed medical image; determining a to-be-processed area image in the to-be-processed medical image; determining a gray average value Rma of an R component and a gray average value Gma of a G component of the to-be-processed region image; and determining the average heme concentration index IHbma of the to-be-processed area image according to the average heme concentration index IHbma. Compared with the prior art that the heme concentration index of a certain selected small area cannot be accurately determined due to the fact that only the heme concentration index of a large area can be obtained, the scheme can quickly and accurately calculate the heme concentration index of the area selected by the user according to the actual needs of the user, and the user experience is improved.
