Compression plate, mammography apparatus, and image capturing system

An image capturing system comprising:

• an ultrasonography apparatus including an ultrasound probe;
• and
• a mammography apparatus including a compression plate,
• wherein the compression plate includes:
• a body part having a box shape with an open top, and
• a guide member that is provided at the body part and that guides the ultrasound probe along a scanning direction of the ultrasound probe,
• wherein the guide member includes:
• a first guide part that guides the ultrasound probe along a first scanning path, and
• a second guide part that guides the ultrasound probe along a second scanning path, and
• wherein the first guide part and the second guide part are disposed such that effective image regions of the ultrasound probe partially overlap with each other in a case in which scanning using the ultrasound probe is performed along the first scanning path and the second scanning path.
