A digital blood vessel projector using a blood vessel image device is provided to obtain projection images of blood vessels by using blood vessel and flow biosensors. In a digital blood vessel projector using a blood vessel image device, first gradient magnetic field applying units(18,19) apply a first gradient magnetic field in parallel to a two-dimensional projection image(32). Nuclear magnetic resonance spin exciting units(22) excite a nuclear magnetic resonance spin of a plane part of a subject perpendicularly to the two-dimensional projection image. A second gradient magnetic field applying unit(14) applies a second gradient magnetic field perpendicularly to the first gradient magnetic field when receiving a free induction decay signal. The two-dimensional projection image is completed by repeatedly exciting the nuclear magnetic resonance spins of the different plane parts of the subject.
